Osteoarthritis (Knee/Hip, conservative vs surgical)

🔬 Practice‑Changing Findings
Evidence from RCTs and meta‑analyses published in the last 12 months.
|
1. Provision of knee bracing for knee osteoarthritis (PROP OA): multicentre, parallel group, superiority, statistician blinded, randomised controlled trial.
BMJ (Clinical research ed.) (2026) - Randomized Controlled Trial
Key Findings
- At 6 months, adding compartment-specific knee bracing to advice/information/exercise improved KOOS-5 more than advice/information/exercise alone (adjusted mean difference 3.39, 95% CI 0.96 to 5.82).
- The effect size was modest (0.24), suggesting a clinically useful but not dramatic incremental benefit from bracing in selected patients.
📋 Practice Implication: Consider knee bracing as an adjunct to exercise-based conservative care when symptoms persist despite standard nonpharmacologic management.
|
2. Efficacy and safety of a single intra-articular injection of mannitol-combined hyaluronan in patients with knee osteoarthritis - A double-blinded randomized clinical study.
The Knee (2026) - Randomized Controlled Trial
Key Findings
- VAS pain improved in both arms, with no significant between-group difference versus saline.
- JETKNEE produced greater improvements in WOMAC pain, function, and total scores across follow-up time points (P < 0.05).
📋 Practice Implication: If considering injection therapy, discuss that functional outcomes may improve even when simple pain scales show smaller between-group differences.
|
3. Pulsed Electromagnetic Field Therapy for Mild-to-Moderate Knee Osteoarthritis: A Double-Blind, Randomized, Placebo-Controlled Clinical Trial.
Journal of cachexia, sarcopenia and muscle (2026) - Randomized Controlled Trial
Key Findings
- PEMF showed significant time-by-treatment effects for knee extension peak torque (p < 0.001) and knee flexion peak torque (p = 0.007).
- These gains were accompanied by functional improvement signals, supporting PEMF as a potential adjunct for mobility-limited knee OA patients.
📋 Practice Implication: For mild-to-moderate OA with weakness-limited function, consider adjunct modalities that improve strength alongside core exercise therapy.
|
4. A comprehensive evaluation and meta-analysis of the efficacy of autologous conditioned serum vs platelet-rich plasma in knee osteoarthritis treatment.
Annals of agricultural and environmental medicine : AAEM (2025) - Meta-Analysis
Key Findings
- Autologous conditioned serum (ACS) showed greater long-term pain relief than PRP, with better VAS improvement at 3 months (p < 0.001), 6 months (p = 0.03), and 24 months (p < 0.001).
- Functional outcomes also favored ACS, with significantly better WOMAC recovery at 3 and 6 months (both p < 0.001).
📋 Practice Implication: When discussing biologic injections, note that formulation choice matters; ACS may provide more durable benefit than PRP in selected patients.
|
5. Total and partial knee arthroplasty versus non-surgical interventions of the knee for moderate to severe osteoarthritis.
The Cochrane database of systematic reviews (2026) - Meta-Analysis
Key Findings
- Evidence synthesis found arthroplasty effective for symptom improvement in moderate-to-severe knee OA compared with non-surgical approaches.
- The same evidence emphasizes procedure-related harm tradeoffs, reinforcing that benefits should be weighed against complication risk in shared decision-making.
📋 Practice Implication: Escalate to surgical referral when optimized conservative therapy fails, but frame surgery as a benefit-risk decision rather than an automatic next step.

Updated high-evidence osteoarthritis literature supports a stepwise strategy: exercise-centered conservative care first, targeted adjuncts when function remains limited, and surgery for persistent moderate-to-severe disability after nonoperative optimization. New comparative data also help clarify which adjuncts may provide incremental benefit and where tradeoffs should be discussed explicitly.
