Platelet Rich Plasma better than Shock Wave for Jumpers' Knee


Jumpers' knee also known as patellar tendinitis is a common problem for basketball and volleyball players among other athletes.  Patients treated with platelet-rich plasma for this condition when compared to shock wave treatment improved more at six and 12 months after treatment.  See abstract below.

This paper adds to the mounting data suggesting PRP is a valuable treatment for chronic tendon related problems such as Jumpers' knee.

Abstract

BACKGROUND:Tendinopathies represent a serious challenge for orthopaedic surgeons involved in treatment of athletes. PURPOSE:To compare the effectiveness and safety of platelet-rich plasma (PRP) injections and focused extracorporeal shock wave therapy (ESWT) in athletes with jumper's knee. STUDY DESIGN:Randomized controlled trial; Level of evidence, 1. METHODS:Forty-six consecutive athletes with jumper's knee were selected for this study and randomized into 2 treatment groups: 2 autologous PRP injections over 2 weeks under ultrasound guidance (PRP group; n = 23), and 3 sessions of focused extracorporeal shock wave therapy (2.400 impulses at 0.17-0.25 mJ/mm(2) per session) (ESWT group; n = 23). The outcome measures were Victorian Institute of Sports Assessment-Patella (VISA-P) questionnaire, pain visual analog scale (VAS), and modified Blazina scale. A reviewer who was blinded as to the group allocation of participants performed outcome assessments before treatment and at 2, 6, and 12 months after treatment. Nonparametric tests were used for within-group (Friedman/Wilcoxon test) and between-group (Kruskal-Wallis/Fisher test) testing, and the significance level was set at .05. RESULTS:The 2 groups were homogeneous in terms of age, sex, level of sports participation, and pretreatment clinical status. Patients in both groups showed statistically significant improvement of symptoms at all follow-up assessments. The VISA-P, VAS, and modified Blazina scale scores showed no significant differences between groups at 2-month follow-up (P = .635, .360, and .339, respectively). The PRP group showed significantly better improvement than the ESWT group in VISA-P, VAS scores at 6- and 12-month follow-up, and modified Blazina scale score at 12-month follow-up (P < .05 for all). CONCLUSION:Therapeutic injections of PRP lead to better midterm clinical results compared with focused ESWT in the treatment of jumper's knee in athletes.
