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.
