PRP injections do work for knee pain, and the clinical evidence supporting them has grown substantially. A 2025 meta-analysis published in the American Journal of Sports Medicine (Bensa et al.) analyzed randomized controlled trials comparing PRP to placebo and found that PRP provides clinically relevant functional improvement at 1, 3, 6, and 12 months and significant pain relief at 3 and 6 months. A separate 2024 meta-analysis from the Mayo Clinic and Hospital for Special Surgery (Oeding et al.) analyzed outcomes from 1,993 patients and found that PRP demonstrated a significantly higher rate of successful outcomes compared to hyaluronic acid (odds ratio 2.19, p = .002), as well as higher rates of symptom relief, lower reintervention rates, and more frequent achievement of the minimal clinically important difference for pain improvement. A 2025 ScienceDirect meta-analysis of 15 double-blind randomized controlled trials (1,632 patients) confirmed PRP superiority over hyaluronic acid in WOMAC pain scores and total scores at 12 months. A 2025 Frontiers in Physiology overview reviewed 29 systematic reviews and meta-analyses of PRP for knee osteoarthritis and found consistent evidence of benefit. Clinical success rates range from 60 to 85% in patients with mild to moderate knee osteoarthritis (Kellgren-Lawrence grades I through III), with benefits typically lasting 6 to 12 months and sometimes up to 24 months. In Tigard, Oregon, Active Pain Relief & Wellness offers PRP therapy guided by this clinical evidence.
How Successful Is PRP for Knees?
PRP injections for knee osteoarthritis have success rates between 60 and 85% in published clinical research, depending on how success is defined and the severity of the patient’s condition. Patients with mild to moderate osteoarthritis (Kellgren-Lawrence grades I through III) consistently achieve the best outcomes. A 2025 AJSM meta-analysis of placebo-controlled randomized trials found clinically significant improvement in both WOMAC function scores and VAS pain scores at every time point measured from 1 through 12 months. The improvement exceeded the minimal clinically important difference (MCID) — meaning patients noticed a real, meaningful change in their daily lives, not just a statistical number on paper.
A July 2024 consensus statement from the European Society of Sports Traumatology, Knee Surgery, and Arthroscopy (ESSKA) and the International Cartilage Regeneration and Joint Preservation Society (ICRS) established clinical guidelines confirming that PRP injections are considered appropriate for patients under 80 years old with Kellgren-Lawrence grade 0 through III knee osteoarthritis who have not responded to conservative treatments. A December 2025 research review in the Open Access Journal of Sports Medicine confirmed that PRP works across all Kellgren-Lawrence grades, with the most significant benefits in early to moderate cases, and that three-injection protocols appear more effective than single injections.
Higher platelet concentrations produce better results. The 2025 AJSM meta-analysis found that high-platelet PRP (approximately 1,000,000 platelets per microliter) provided superior pain relief and more durable functional improvement compared to low-platelet preparations. This is why the quality of PRP preparation matters — not all PRP is created equal. Patients in Tigard, Oregon receive high-concentration PRP preparation at Active Pain Relief & Wellness.
What Is the Downside of PRP Injections?
PRP injections are considered very safe because they use your own blood, eliminating the risk of allergic reaction or disease transmission. However, there are some downsides to be aware of. The most common side effect is temporary pain, swelling, or stiffness at the injection site, which occurs in approximately 10 to 15% of patients and typically resolves within a few days. Some patients experience a brief inflammatory flare in the knee lasting 24 to 72 hours after injection, which is actually part of the healing response.
The main practical downsides are cost and insurance coverage. Most insurance plans, including Medicare, do not cover PRP injections because they are classified as investigational. The average cost per injection is approximately $500 to $900, and most protocols call for 1 to 3 injections. A Cleveland Clinic cost-effectiveness analysis published in the Journal of Bone and Joint Surgery found that the total healthcare cost of PRP injections was approximately $26,619 over time, compared to $26,235 for total knee arthroplasty — making PRP comparable in total cost while being far less invasive. PRP is also not a permanent cure. Benefits typically last 6 to 12 months and may require repeat treatments. The 2025 Frontiers in Physiology overview noted that heterogeneity in PRP preparation methods remains a limitation across studies, meaning results can vary depending on the clinic’s preparation protocol. Patients in Tigard, Oregon receive a transparent cost discussion at their initial consultation.
How Long Does It Take for PRP To Work on the Knees?
Most patients begin noticing improvement 2 to 6 weeks after a PRP injection. Unlike cortisone, which provides near-immediate but short-lived relief, PRP works gradually by stimulating your body’s natural healing processes. Growth factors released by the concentrated platelets reduce inflammation, promote cell repair, and stimulate the production of hyaluronic acid and collagen within the joint over weeks to months.
The timeline typically follows this pattern. During weeks 1 through 2, some patients experience a brief increase in pain or swelling as the inflammatory healing response begins. During weeks 2 through 6, inflammation subsides and new tissue repair begins, with most patients reporting noticeable pain reduction. During months 2 through 6, improvement continues to build as tissue remodeling progresses, and this is typically when patients report the most significant gains. From months 6 through 12, benefits plateau and remain stable, with some studies showing continued improvement up to 24 months. A PMC prospective study of 33 patients with grade 2 and 3 knee osteoarthritis (Egyptian Journal of Radiology and Nuclear Medicine, 2024) showed VAS pain scores dropping from 7.0 at baseline to 2.76 at 12 months after three PRP injections — a 61% reduction in pain. Patients in Tigard, Oregon receive follow-up monitoring at 6 and 12 weeks to track their progress at Active Pain Relief & Wellness.
Can PRP Regrow Knee Cartilage?
The honest answer is that PRP has not been conclusively proven to regrow cartilage in humans. A 2022 ScienceDirect systematic review and meta-analysis that examined MRI evidence from multiple studies concluded that PRP treatment was not associated with a significant increase in cartilage thickness and that the current literature does not support PRP as a chondrogenic (cartilage-growing) treatment for knee osteoarthritis. A 2024 PMC study (Brittberg, CARTILAGE journal) analyzing treatment of knee cartilage lesions similarly found no definitive evidence of cartilage regeneration from PRP alone.
However, there are nuances. Some individual studies have shown promising results. A 2022 Cureus study of 30 patients who received three PRP injections found statistically significant improvement in cartilage thickness (femoral and trochlear cartilage) measured by ultrasound at 180 days. One RCT found that nearly 50% of patients who received leukocyte-poor PRP had more than one grade of osteoarthritis improvement on MRI at 6 months, compared to only 8% with hyaluronic acid injections. Laboratory research has shown that PRP can reduce cartilage cell death, stimulate cartilage matrix production, and increase hyaluronic acid secretion from synovial cells. The practical takeaway: PRP reliably reduces pain and improves function, may slow cartilage degradation (chondroprotection), but should not be marketed primarily as a cartilage regeneration treatment. Patients in Tigard, Oregon receive honest expectations about what PRP can and cannot do.
Is PRP Better Than Steroid Injections for Knee Pain?
For long-term results, yes. Multiple meta-analyses and randomized controlled trials have demonstrated that PRP outperforms cortisone injections beyond the 3-month mark. A 2025 ScienceDirect systematic review analyzing 60 years of literature (356 studies, 24,435 patients) found that PRP has been documented in more studies and in larger patient numbers than cortisone, and that the evidence strongly suggests reconsidering guidelines that favor cortisone over PRP. A 2024 Arthroscopy network meta-analysis (Jawanda et al.) found that PRP, bone marrow aspirate concentrate, and hyaluronic acid all outperformed corticosteroids in pain and function scores at a minimum of 6 months.
The key differences between PRP and cortisone are straightforward. Cortisone provides fast relief (within days) that typically wears off by 2 to 3 months. PRP takes 2 to 6 weeks to show improvement but typically lasts 6 to 12 months or longer. Cortisone is an anti-inflammatory that masks symptoms. PRP delivers growth factors that stimulate tissue repair. Repeated cortisone injections have been associated with accelerated cartilage breakdown and potential joint damage in some studies. PRP has not been associated with joint damage. A PMC randomized controlled trial comparing a single PRP injection to a single cortisone injection found that both groups improved in the first month, but PRP demonstrated statistically significant superiority at the 1-year follow-up. Patients in Tigard, Oregon can discuss which injection approach is right for their specific situation at Active Pain Relief & Wellness.
PRP vs. Other Knee Injections: Clinical Evidence Comparison
| Injection Type | Onset of Relief | Duration of Benefit | Cartilage Impact | Typical Cost per Injection | Insurance Coverage |
|---|---|---|---|---|---|
| PRP (Platelet-Rich Plasma) | 2–6 weeks | 6–12+ months | May be chondroprotective; no proven damage | $500–$900 | Rarely covered |
| Cortisone (Corticosteroid) | 1–7 days | 2–3 months | May accelerate cartilage loss with repeated use | $100–$300 | Usually covered |
| Hyaluronic Acid (Viscosupplementation) | 2–4 weeks | 3–6 months | Lubricates joint; no proven structural change | $300–$800 | Often covered |
| BMAC (Bone Marrow Aspirate Concentrate) | 4–8 weeks | 6–12+ months | Contains stem cells; similar efficacy to PRP in head-to-head trials | $2,000–$5,000+ | Rarely covered |

Can PRP Be Used Instead of Knee Replacement?
PRP can delay knee replacement surgery but is not a permanent substitute for it in patients with severe, end-stage osteoarthritis (Kellgren-Lawrence grade IV, bone-on-bone). A Cleveland Clinic cost-effectiveness analysis modeled a 55-year-old patient with grade II or III knee osteoarthritis and found that PRP injections can delay total knee arthroplasty by approximately 1 year while providing comparable quality-adjusted life-years. Other research suggests PRP may delay knee replacement by up to 5 years in some patients.
PRP works best for patients with mild to moderate osteoarthritis who still have some cartilage remaining. The July 2024 ESSKA/ICRS consensus guidelines specifically stated that PRP is not considered appropriate as a first-line treatment for grade IV knee osteoarthritis. For patients with severe bone-on-bone arthritis, knee replacement remains the most reliable long-term solution. However, for patients who are too young for knee replacement (most surgeons prefer to wait until at least age 55 to 60 because artificial joints last 15 to 20 years), who have medical conditions that increase surgical risk, or who simply want to delay surgery as long as possible, PRP is an evidence-based option that can provide meaningful relief. Patients in Tigard, Oregon receive a thorough evaluation to determine whether PRP is appropriate for their stage of knee osteoarthritis at Active Pain Relief & Wellness.
Who Is a Good Candidate for PRP Knee Injections?
The best candidates for PRP knee injections meet most or all of the following criteria based on the clinical evidence. First, they have mild to moderate knee osteoarthritis (Kellgren-Lawrence grades I through III) confirmed on X-ray or MRI. Second, they have tried and failed conservative treatments like physical therapy, anti-inflammatory medications, and lifestyle modifications. Third, they are under 80 years old (the ESSKA/ICRS consensus age guideline). Fourth, they have realistic expectations — PRP reliably reduces pain and improves function but does not reverse advanced joint damage. Research consistently shows that younger patients (under 60) with lower-grade osteoarthritis achieve the best outcomes, with up to 85% experiencing significant pain reduction.
Patients who may not be ideal candidates include those with severe bone-on-bone osteoarthritis (grade IV) as a sole treatment, active joint infection, blood disorders or platelet dysfunction, active cancer, and those on anticoagulant therapy (relative contraindication — discuss with your provider). Being overweight does not disqualify you from PRP, but weight management alongside treatment improves outcomes because every 10 extra pounds adds 30 to 60 pounds of force on the knee with each step. Patients in the Tigard and Portland, Oregon area receive a complete candidacy assessment including imaging review.
Is It Possible To Regenerate Knee Cartilage Without Surgery?
True cartilage regeneration without surgery remains extremely limited because adult articular cartilage has very poor self-healing capacity — it has no blood supply, no nerve supply, and very few cells compared to other tissues. However, several non-surgical approaches can slow cartilage loss, reduce pain, and improve joint function. PRP injections deliver growth factors that may protect remaining cartilage (chondroprotection), reduce inflammation, and stimulate production of hyaluronic acid and collagen in the joint. Hyaluronic acid injections lubricate the joint and may provide modest chondroprotection. Weight loss reduces mechanical stress on cartilage (every pound lost removes approximately 4 pounds of pressure from the knee).
Exercise — particularly low-impact activities like swimming, cycling, and walking — improves blood flow to the joint, strengthens supporting muscles, and stimulates cartilage nutrition through joint loading and unloading cycles. Supplements like glucosamine (1,500 mg daily), chondroitin (1,200 mg daily), and collagen peptides have shown modest benefits in some studies, though the American College of Rheumatology currently recommends against glucosamine and chondroitin for knee osteoarthritis due to inconsistent evidence. Anti-inflammatory diets rich in omega-3 fatty acids, fruits, and vegetables may reduce the inflammatory environment that accelerates cartilage breakdown. The most honest answer: you cannot grow new, normal hyaline cartilage non-surgically, but you can meaningfully slow its loss and manage symptoms effectively. Patients in Tigard, Oregon receive a comprehensive cartilage preservation plan.
What Vitamin Helps Regrow Cartilage?
No single vitamin has been proven to regrow cartilage in human clinical trials. However, several vitamins and nutrients play important roles in cartilage maintenance and protection. Vitamin C is essential for collagen synthesis — collagen is the structural protein that makes up approximately 60% of cartilage’s dry weight. Without adequate vitamin C, the body cannot produce or repair collagen effectively. Vitamin D supports bone health and has been associated with slower osteoarthritis progression in some studies, though a direct cartilage regeneration effect has not been confirmed. Vitamin K (particularly K2) may help regulate calcium metabolism and has been linked to healthier cartilage in observational studies.
Beyond vitamins, certain supplements have shown more direct cartilage-related effects in laboratory and some clinical studies. Collagen peptides (particularly type II collagen) provide the amino acids needed for cartilage repair. A 2025 PMC systematic review (Brueckheimer et al.) found that type I collagen hydrolysate significantly improved joint pain and mobility. Glucosamine and chondroitin are structural building blocks of cartilage. Omega-3 fatty acids have anti-inflammatory properties that may slow cartilage degradation. The most evidence-based approach is combining adequate nutrition with exercise and, when appropriate, regenerative treatments like PRP. Patients in Tigard, Oregon receive supplement recommendations based on their individual lab work and imaging findings.
Which Food Repairs Knee Cartilage?
No single food can repair damaged knee cartilage, but several foods provide the building blocks and anti-inflammatory compounds that support cartilage health and may slow further degradation. Fatty fish like salmon, sardines, mackerel, and tuna provide omega-3 fatty acids that reduce joint inflammation and may slow cartilage breakdown. Bone broth contains collagen, glucosamine, chondroitin, and proline — all components of cartilage and synovial fluid. Berries (blueberries, strawberries, pomegranates) are rich in vitamin C for collagen production and polyphenols that help stabilize cartilage collagen. Leafy greens like spinach and kale provide vitamin K, calcium, and antioxidants. Citrus fruits provide high levels of vitamin C. Nuts and seeds provide magnesium and omega-3 fatty acids. Eggs and lean proteins provide the amino acids necessary for tissue repair.
A 2024 Cureus study found that a six-week standardized pomegranate extract improved physical function and reduced cartilage degradation enzymes in knee osteoarthritis patients. The Mediterranean diet — rich in olive oil, fish, fruits, vegetables, nuts, and whole grains — has been associated with lower inflammation and reduced osteoarthritis symptom severity in multiple studies. A 2025 PMC narrative review confirmed that anti-inflammatory diets were linked to lower inflammation and reduced symptom severity. Foods to minimize include processed foods high in sugar and refined carbohydrates, which promote systemic inflammation. Patients in Tigard, Oregon receive anti-inflammatory dietary guidance as part of their treatment plan at Active Pain Relief & Wellness.
What Exercises Help Cartilage Recovery?
Low-impact exercises that strengthen the muscles around the knee while minimizing joint stress are the most beneficial for cartilage health. Strong quadriceps, hamstrings, and calf muscles act as shock absorbers, reducing the load on cartilage during daily activities. A 2025 PMC narrative review found that regular exercise reduced pain, improved function, and supported joint health in osteoarthritis patients.
The best exercises for knee cartilage recovery include straight leg raises (lying on your back, raise one leg 6 to 12 inches, hold 5 seconds, lower slowly — strengthens quadriceps without bending the knee), wall squats (back against wall, slide down to a partial squat, hold 5 seconds — builds quadricep and glute strength), heel slides (lying on your back, slide your heel toward your buttock to bend the knee, then back out — improves range of motion), hamstring curls (standing or lying, bend your knee to bring your heel toward your buttock — strengthens the back of the thigh), swimming and water aerobics (buoyancy reduces joint stress by up to 90% while providing resistance), cycling (low-impact, promotes joint mobility and blood flow to cartilage), and walking on flat surfaces (30 minutes most days — stimulates cartilage nutrition through gentle loading). Aim for 3 to 4 sessions per week. Avoid high-impact activities like running on hard surfaces, deep squats, and jumping, which increase cartilage stress. Patients in Tigard, Oregon receive exercise prescription as part of their PRP treatment protocol.
Is Walking Good for Damaged Knee Cartilage?
Yes, walking is generally good for damaged knee cartilage when done appropriately. Cartilage does not have its own blood supply — it receives nutrients from synovial fluid through a process of compression and decompression during movement. Walking stimulates this process, essentially “feeding” the cartilage. Regular walking also strengthens the muscles around the knee, which reduces the load on the cartilage itself, and helps maintain a healthy weight, which further reduces joint stress.
The key is moderation and appropriate surfaces. Walk on flat, even surfaces rather than hills or uneven terrain. Wear supportive shoes with good cushioning. Start with 10 to 15 minutes and gradually build to 30 minutes most days. If pain increases during or after walking, reduce the duration or intensity. Avoid pushing through significant pain, which can indicate you are overloading the joint. For patients with more advanced cartilage damage, walking in a pool (aquatic walking) provides the movement benefits with dramatically reduced joint stress. Patients in Tigard, Oregon receive individualized activity recommendations.
What Is the Strongest Natural Anti-Inflammatory?
Curcumin (the active compound in turmeric) is widely considered the strongest natural anti-inflammatory with the most clinical evidence for joint pain. A 2025 PMC systematic review found that curcumin supplements showed modest benefits for osteoarthritis with a favorable safety profile. Multiple randomized controlled trials have shown that curcumin (typically 500 to 1,000 mg daily of a bioavailable formulation) can reduce knee osteoarthritis pain comparably to some NSAIDs. Curcumin works by inhibiting NF-kB, a key inflammatory signaling pathway involved in cartilage breakdown.
Other strong natural anti-inflammatories include omega-3 fatty acids (EPA and DHA from fish oil — typically 2,000 to 3,000 mg daily), Boswellia serrata (frankincense extract — has shown pain reduction in knee OA trials), ginger extract, and bromelain (a pineapple-derived enzyme). While these natural anti-inflammatories can complement treatment, they are not replacements for evidence-based interventions like PRP, physical therapy, or weight management. They also interact with some medications, particularly blood thinners. Patients in Tigard, Oregon receive guidance on which natural supplements are appropriate for their specific situation.
How Do I Lubricate My Knee Cartilage?
Your knee is naturally lubricated by synovial fluid, a viscous liquid produced by the synovial membrane that lines the joint capsule. Synovial fluid contains hyaluronic acid, which provides the slippery, cushioning properties that allow smooth joint movement. You can support natural joint lubrication through several strategies. Stay well hydrated — synovial fluid is primarily water. Move regularly — joint movement stimulates synovial fluid production and distribution. Eat omega-3 rich foods — these support healthy synovial membrane function. Consider hyaluronic acid supplements or injections — viscosupplementation directly adds lubricant to the joint.
PRP injections may also improve joint lubrication indirectly. Research has shown that PRP stimulates synovial fibroblasts to produce more hyaluronic acid, enhancing the joint’s natural lubricating system. This is one mechanism by which PRP provides lasting improvement — rather than simply adding lubricant (as hyaluronic acid injections do), PRP may stimulate the joint to produce more of its own. Patients in Tigard, Oregon receive a multimodal joint health plan at Active Pain Relief & Wellness.
Frequently Asked Questions
What Is the New Injection for Knee Cartilage?
Several new injectable treatments for knee cartilage are in development or recently approved beyond traditional PRP, cortisone, and hyaluronic acid. Bone marrow aspirate concentrate (BMAC) contains mesenchymal stem cells and growth factors drawn from your own bone marrow. Head-to-head trials have shown BMAC produces results similar to PRP, though it is more expensive ($2,000 to $5,000+). Autologous protein solution (APS), marketed as nSTRIDE, is a concentrated injection that targets specific inflammatory molecules in the joint. Next-generation PRP formulations using leukocyte-poor preparations and optimized platelet concentrations are showing improved outcomes. The 2024 PMC review of cartilage treatments noted that single-stage cell techniques, mesenchymal stem cells, and gene therapy represent the future frontier, though most remain in early clinical study. PRP remains the most accessible, well-studied, and cost-effective regenerative injection currently available. Patients in Tigard, Oregon receive access to the latest injection options.
What Is the Best Joint Supplement for Knees?
Based on the available clinical evidence, the most commonly recommended joint supplements for knee osteoarthritis include glucosamine sulfate (1,500 mg daily), chondroitin sulfate (1,200 mg daily), collagen peptides (2.5 to 10 grams daily), curcumin/turmeric (500 to 1,000 mg daily of a bioavailable formulation), omega-3 fish oil (2,000 to 3,000 mg daily), and vitamin D (1,000 to 2,000 IU daily, especially if deficient). The Arthritis Foundation notes that evidence is mixed for most supplements, and the American College of Rheumatology currently recommends against glucosamine and chondroitin, though many patients report subjective benefit. Collagen peptides have growing evidence: a 2025 PMC systematic review of 36 RCTs found that type I collagen hydrolysate significantly improved joint pain and mobility. The most important interventions for knee health remain weight management, exercise, and evidence-based treatments like PRP — supplements should complement, not replace, these approaches. Patients in Tigard, Oregon receive personalized supplement recommendations.
How To Avoid Knee Replacement When Bone on Bone
For patients with severe bone-on-bone knee osteoarthritis (Kellgren-Lawrence grade IV), avoiding knee replacement permanently is often not realistic. However, several strategies can delay surgery and improve quality of life in the interim. PRP injections may provide some pain relief even in grade IV patients, though results are less predictable than in earlier stages. Weight loss is critical — every pound lost removes approximately 4 pounds of pressure from the knee. Physical therapy focusing on quadriceps strengthening, range of motion, and gait training helps maximize function. Knee bracing (unloader braces) can redistribute weight away from the most damaged compartment. Low-impact exercise like swimming and cycling maintains fitness without worsening joint damage. Activity modification — avoiding stairs, prolonged standing, and high-impact activities when possible — reduces daily pain. For patients in the Tigard and Portland, Oregon area, Active Pain Relief & Wellness provides a comprehensive non-surgical management plan.
What Vitamin Am I Lacking if My Knee Hurts?
Several nutrient deficiencies can contribute to or worsen knee pain. Vitamin D deficiency is the most common — it weakens bones, impairs muscle function, and may accelerate osteoarthritis progression. An estimated 40% or more of American adults have insufficient vitamin D levels. Magnesium deficiency can cause muscle cramps, weakness, and increased inflammation. Omega-3 fatty acid deficiency (common in typical Western diets) promotes a pro-inflammatory state that worsens joint pain. Vitamin B12 deficiency can cause nerve-related pain and weakness. Iron deficiency can cause generalized aching and fatigue. A simple blood test can identify these deficiencies. However, knee pain is more commonly caused by structural issues (osteoarthritis, meniscus tears, ligament injuries) or overuse than by vitamin deficiency alone. Patients in Tigard, Oregon receive lab work to screen for nutritional deficiencies as part of their evaluation.
How To Increase Blood Flow to Knee Cartilage
Cartilage itself does not have blood vessels — it receives nutrition through diffusion from surrounding synovial fluid and subchondral bone. However, increasing blood flow to the tissues surrounding the knee (muscles, synovial membrane, subchondral bone) supports cartilage health. Regular low-impact exercise (walking, cycling, swimming) is the most effective way to improve circulation to the knee. Gentle massage around the knee can improve local blood flow. Warm compresses or heating pads before exercise increase circulation. Anti-inflammatory foods and supplements support healthy blood flow. Avoiding prolonged sitting or standing (change positions every 30 to 45 minutes) prevents stagnation. Compression sleeves can provide gentle support and promote circulation during activity. Patients in Tigard, Oregon receive circulation-supporting strategies as part of their treatment plan.
What Is the Best Strengthening Exercise for Bone on Bone Knees?
For bone-on-bone knees, the goal is to strengthen the muscles surrounding the joint without increasing cartilage stress. The single best exercise is the straight leg raise — lying on your back, tighten your quadriceps, and raise your leg 6 to 12 inches off the ground, hold for 5 seconds, then lower slowly. This strengthens the quadriceps (the most important knee-supporting muscle) without bending the knee or compressing the joint. Other excellent options include seated leg extensions with light resistance, isometric quadriceps contractions (pressing your knee into a rolled towel on the floor), hamstring curls, calf raises, and pool-based exercises where buoyancy reduces joint stress by up to 90%. Avoid deep squats, lunges with heavy weights, leg presses at deep angles, and any exercise that causes sharp or worsening pain. Consistency matters more than intensity — 3 to 4 sessions per week of gentle strengthening produces better long-term results than occasional intense workouts. Patients in the Tigard, Oregon area receive exercise programming at Active Pain Relief & Wellness.
