Abstract
OBJECTIVE
To evaluate the impact of autologous platelet rich plasma (PRP) combined with steroid injection on hand grip strenght, pain and patient satisfaction in the treatment of lateral epicondylitis.
METHODS
84 patients, mean age 42.6 (23-62) years, diagnosed with unilateral resistant lateral epicondylitis was evaluated retrospectively. Group1 consisted of patients treated with local steroid injection (0,5ml Bethametasone+0.25 ml Prilokain) and PRP within 1 week interval to extensor carpi radialis brevis origo while group 2 consisted of patients who were subjected to single dose local PRP injection to the same localisation. Pretreatment and posttreatment 15-30-60 day hand grip strenght and Verhaar functional score data were evaluated.
RESULTS
Mean pretreatment grip strenght of group1 patients were 0.42±0.17 (0.18-0.61) bar whereas posttreatment day 60 increased to 0.68±0.11(0.50-0.85). Group 2 mean pretreatment grip strenght was found to be 0.45±0.15 (0.19-0.84) bar, whereas posttreatment day 60 increased to 0.66±0.10 (0.44-082). Compared to group 2, the percentage of grip strenght increase in group 1 was significantly higher at days 15 and 30, whereas there was no difference at day 60 between groups. (p=0.277). Compared to group 2, Verhaar scores were found to be higher in group1 at days 15 and 30, whereas there was no difference between groups at day 60.
CONCLUSION
Compared to PRP alone, steroid injection 1 week prior PRP administration can be preferred as an effective and safe method in cases which early maintanance of decreased grip strenght is mandatory.
