Primary Outcome Measures:
Secondary Outcome Measures:
Consecutive 100 patients with anterior knee pain and compatible with inclusion criteria. Before treatment, an independent physiotherapist evaluates whether femoral internal rotation or not via physical therapy, and another studying nurse records the visual analog scale and measures Q angle. After evaluation, McConnell taping is applied to these patients. Two weeks later, outcomes are recorded including visual analog scale, satisfactory, and complication. The outcomes are compared between those with and without femoral internal rotation.
