Comment on "Effects of kinesiotaping versus non-steroidal anti-inflammatory drugs and physical therapy for treatment of pes anserinus tendino-bursitis: a randomized comparative clinical trial".

OBJECTIVE Pes anserinus tendino-bursitis is a condition caused by repetitive friction over the bursa or direct trauma to knee joint and it presents with proximal medial tibial pain and swelling. The aim of this study is to determine the effects of kinesiotaping in comparison with naproxen and physical therapy in treatment of pes anserinus tendino-bursitis. METHODS In a randomized comparative clinical trial 56 patients with clinical diagnosis of pes anserinus tendino-bursitis were randomly assigned to kinesiotaping and naproxen/physical therapy (28 patients in each group). Kinesiotaping on the tender area in the form of space-correction (lifting) technique was used and repeated for three times with a one-week interval. Another group received naproxen (250mg TID for 10 days) and ten sessions of daily physical therapy. The visual analog scale (VAS) was used for evaluation of pain. The depth of swelling of the area was measured with sonography before and after treatment. Wilcoxon signed ranks test has been used for determining the influence of interventions on pain (VAS) and swelling scores in each group. The ANCOVA (Analysis of covariance) test was applied for comparing the influence of interventions on VAS and swelling scores after adjustment for co-variables. RESULTS At end of the study, 27 patients remained in the kinesiotaping group and 19 patients in naproxen/physical therapy group. Treatment with kinesiotaping significantly decreased the pain (P=0.0001) and swelling scores (P=0.0001) in comparison with naproxen/physical therapy after adjustment for baseline characteristics. Kinesiotaping was safe without any complications except for a mild local skin irritation in one patient. CONCLUSION Kinesiotaping is more effective than naproxen plus physical therapy in reduction of pain and swelling in patients with pes anserinus tendino-bursitis.
