🔬 Practice-Changing Findings
Evidence from RCTs and meta-analyses published in the last 12 months.

1. Platelet-Rich Plasma Does Not Improve Pain or Function in Patients With Lateral Epicondylitis as Compared With Placebo: A Meta-analysis of Randomized Clinical Trials.

The American journal of sports medicine (2026) - Meta-analysis of randomized clinical trials

Key Findings

  • Across 6 RCTs with 355 patients, PRP did not improve pain versus placebo at 4 weeks (SMD 0.08), 8-12 weeks (SMD -0.36), or 24-26 weeks (MD -1.58).
  • Functional outcomes also showed no PRP benefit versus placebo at 4 weeks (SMD 0.09), 12 weeks (SMD -0.09), or 24-26 weeks (SMD 0.13), and adverse events were similar (RR 1.66).

📋 Practice Implication: Do not offer standard PRP as routine care for lateral epicondylitis when the realistic comparator is placebo-level benefit; reinforce exercise-based and other conservative strategies first.

2. Platelet Concentration Explains Variability in Outcomes of Platelet-Rich Plasma for Lateral Epicondylitis: A High Dose Is Critical for a Positive Response: A Systematic Review and Meta-analysis With Meta-regression.

The American journal of sports medicine (2025) - Systematic review and meta-analysis with meta-regression

Key Findings

  • In 13 RCTs with 791 patients, high-dose PRP improved pain versus alternative treatments at final follow-up (MD -1.31; 95% CI -1.87 to -0.75; P < .001).
  • Low-dose PRP showed no difference versus comparators (MD 0.08; 95% CI -0.51 to 0.68; P = .79), and platelet concentration explained 58.5% of between-study outcome heterogeneity.

📋 Practice Implication: If PRP is used despite mixed overall evidence, document and standardize a supraphysiologic platelet concentration rather than treating all PRP preparations as interchangeable.

3. Comparative efficacy of extracorporeal shockwave therapy and ultrasound on pain and functional outcomes in lateral epicondylitis: a systematic review and meta-analysis.

European journal of orthopaedic surgery & traumatology (2025) - Systematic review and meta-analysis

Key Findings

  • Across 9 RCTs with 654 participants, ESWT reduced pain more than ultrasound (MD -0.90; 95% CI -1.28 to -0.52; p < 0.0001).
  • Functional improvement did not differ significantly on PRTEE (MD -5.28; 95% CI -10.61 to 0.04; p = 0.05).

📋 Practice Implication: When choosing between device-based conservative therapies, prefer ESWT if pain reduction is the main short-term goal, but do not expect a clear functional advantage over ultrasound.

4. Comparing the Use of Physiotherapy, Shockwave Therapy, Prolotherapy, and Platelet-Rich Plasma for Chronic Lateral Epicondylosis: A Prospective, Randomized Controlled Trial With 2-Year Follow-up.

The American journal of sports medicine (2025) - Prospective randomized controlled trial

Key Findings

  • At 24 months, PRP reduced DASH scores by 31.18 points versus 18.70 with physiotherapy and 17.62 with ESWT (P < .01) in chronic lateral epicondylosis.
  • PRP improved satisfaction to 4.60 +/- 0.9, and prolotherapy also improved satisfaction more than physiotherapy and ESWT while all groups improved beyond the 10-point DASH minimal clinically important difference.

📋 Practice Implication: For patients with symptoms persisting beyond 6 months despite prior nonoperative care, discuss PRP or prolotherapy as options with better long-term durability than physiotherapy or ESWT alone.

5. Effects of Blood Flow Restriction Training Combined With Conventional Physical Therapy on Pain, Muscle Architecture, Strength, Function, and Psychosocial Outcomes in Chronic Lateral Epicondylitis: A Pilot Randomized Controlled Trial.

Medical science monitor : international medical journal of experimental and clinical research (2026) - Pilot randomized controlled trial

Key Findings

  • After 6 weeks, BFRT plus conventional therapy produced greater improvements than conventional therapy alone in PRTEE (P = 0.001), Quick-DASH (P = .025), FABQ (P = .039), and SF-12 physical scores (P = .003).
  • Both groups improved pain, strength, and function, but between-group differences in pain and strength were not significant, and no adverse events were reported.

📋 Practice Implication: Use BFRT as a rehabilitation adjunct when the priority is improving function, fear-avoidance, and quality of life without adding high-load stress, while recognizing that pain and strength gains may track standard therapy.

💡 Summary

Recent elbow syndrome evidence is dominated by lateral epicondylitis and suggests that routine PRP remains unsupported against placebo, while outcomes vary substantially by platelet concentration and treatment protocol. Among nonoperative options, ESWT improves pain more than ultrasound, adjunct rehabilitation strategies can improve recovery, and in chronic refractory disease PRP or prolotherapy may provide the most durable gains over 2 years.
