Knee pain treatment Gilbert: know what to do next

Daily use often explains the soreness

Arthritis can make your knee stiff after sitting. It'll ache on stairs or when you stand. Swelling won't always stay.

Where and when it hurts both matter.

A tendon is the tough band joining muscle to bone. It'll hurt during one exact motion. Your doctor can match that pain with the exam.

Less strain can settle a flare

Cut back on the task that raised soreness. Keep some easy motion in your day. A brace or cane may take pressure off.

Cold may calm swelling for a while.

Warmth can loosen your knee before movement. Keep heat and cold off bare skin. Stop an exercise if the knee buckles or pain turns sharp. If a cane changes your balance, ask someone to check its height. It shouldn't make you lean sideways.

Ongoing limits deserve an exam

Book a visit if soreness keeps returning. Don't wait as swelling or poor balance grows. Tell the clinician how your knee moves.

Take your medicines and an old X-ray.

Name the daily task you want back. That'll keep the visit tied to your life. You'll want that detail during the exam. QC Kinetix's Chandler team offers PRP, a regenerative treatment made by drawing and spinning your blood before placing the prepared part in your knee.

1. In the 68-week STEP 9 trial, 407 participants with obesity (mean BMI 40.3) and moderate knee OA with at least moderate pain were randomized 2:1 to once-weekly semaglutide 2.4 mg or placebo alongside diet and activity counselling. Weight change was -13.7% vs -3.2%, and WOMAC pain improved -41.7 vs -27.5 points (both P<0.001). Gastrointestinal adverse events drove discontinuation in 6.7% vs 3.0%.

2. A 2026 systematic review and meta-analysis of eight sham-controlled RCTs (n=627) found genicular nerve ablation (radiofrequency or cryoneurolysis) reduced knee OA pain versus sham at 12 weeks (MD -1.65; 95% CI -2.57 to -0.74) and improved WOMAC function (MD -11.37), with high heterogeneity (I2 83-91%) and no serious adverse events reported. The population studied was patients INELIGIBLE for arthroplasty.

3. A 2026 Cochrane review searching from 2010 to January 2025 found only ONE randomised trial (100 participants, Denmark) comparing knee arthroplasty with non-surgical treatment. Low-certainty evidence indicated TKA may reduce pain at one year by a clinically important margin (MD 17.60, 95% CI 8.25 to 26.95) and may improve function by an amount that might not be clinically important (MD 12.40), with probably no clinically important difference in health-related quality of life.

The 2019 ACR/Arthritis Foundation guideline makes STRONG recommendations for exercise, weight loss in people with overweight or obesity, self-efficacy and self-management programs, tai chi, cane use, tibiofemoral bracing, topical NSAIDs, oral NSAIDs and intra-articular glucocorticoid injections in knee OA; radiofrequency ablation for knee OA is only a conditional recommendation.

5. High-quality evidence from 44 trials (3,537 participants) shows land-based exercise reduced knee OA pain by an equivalent of 12 points on a 0-100 scale (SMD -0.49) immediately after treatment, with moderate-quality evidence for a ~10-point function gain; the effect attenuated but persisted at 2-6 months (SMD -0.24). No serious adverse events were reported in any included trial.
