Brief Summary

Patellar subluxation is a common disorder that may cause patellofemoral pain syndrome. The efficiency of patellar taping in the treatment of patellofemoral pain syndrome has been reported good outcomes in most patients. However, some studies reported less effective in patients with higher body mass index, larger lateral patellofemoral angle, and smaller Q angle. The investigators hypothesized that femoral internal rotation is a negative factor to the patellar taping. The investigators enroll consecutive 100 patients with anterior knee pain and radiographic evidence of patellar subluxation. The investigators determine femoral rotation via physical examination. The visual analogue scale was evaluate to compare the result between the those with and without femoral internal rotation.
