The effects of patellar taping on patellofemoral incongruence. A computed tomography study.

Patellar taping for the purpose of patellar medialization is a nonoperative rehabilitation technique used in the treatment of patellofemoral pain. Despite early reports of excellent success rates, the indications for this treatment and its efficacy on patellofemoral pain are unclear. The present computed tomography study was undertaken to evaluate the effect of patellar taping on patellofemoral incongruence. Sixteen female patients (age range, 16 to 25 years) with anterior knee pain related to patellofemoral incongruence underwent computed tomography examination with their quadriceps muscles relaxed and contracted both before and after patellar taping. Patellar lateralization was measured as lateral patellar displacement, and patellar tilt was measured as lateral patellar angle. Patellar taping did not significantly affect patellofemoral lateralization or tilt. The results of this study do not support the use of this method for passive correction of patellofemoral incongruence. Although patellar taping may well be effective in controlling anterior knee pain during physical therapy, it does not do so by medializing the patella
