Objective: The aim of this study was to evaluate the effect of anterior knee pain on clinical outcome, activity level, strength, functional tests, proprioception, and balance in patients who had anterior cruciate ligament (ACL) reconstruction with a patellar tendon (PT) autograft.Materials and Methods: Thirtyeight patients with a mean age of 27,6, who had undergone ACL reconstruction with a PT autograft and followed with a modified accelerated rehabilitation program, were included in the study. Isokinetic muscle strength of knee extension and flexion were measured using a Cybex® isokinetic dynamometer. SportKAT® device was used to assess the static balance. For proprioceptive assessment, an isokinetic dynamometer was used. Active repositioning was measured at knee flexions of 40°, 20°, and 5°. Activity level of the patients was assessed with Tegner activity scale and subjective functional results were evaluated using the Lysholm knee score. Single leg hop, triple leg hop, and onelegged crossover hop tests were used for objective functional testing. Anterior knee pain was evaluated with a 110 centimeters visual analog scale.Results: Fifteen patients (39.5%) had anterior knee pain. Lysholm and Tegner scores were significantly lower in patients with anterior knee pain (p0.05). For all parameters, power analysis was conducted.Conclusion: Anterior knee pain after ACL reconstruction with PT autograft affects the patients’ Lysholm and Tegner activity scores whereas it has no effect on muscle strength, functional tests, proprioception and balance.
