AIMS: In 40 patients, we attempted to investigate the efficacy of electromyography-biofeedback (EMG-B) on quadriceps muscle strength after arthroscopic meniscectomy. METHODS: The patients were randomly divided into two groups each consisting of 20 subjects. For the control group, a classical exercise program was given (five sessions of EMG-B application for 2 weeks postoperatively). Range of motions, Lysholm knee score, EMG electrical activity values of vastus medialis obliques (VMO), and vastus lateralis (VL) were measured pre- and postoperatively on the 3rd and 14th day, and at the 6th week. RESULTS: When the ranges of motion values were compared, a significant difference (for average values of knee flexion angle) was found on the 14th day and 6th week in favour of biofeedback group (p < 0.05). When Lysholm knee scores on the 14th day and 6th week were compared in the control and biofeedback groups, and maximum contraction and average contraction values of VMO, VL muscles were compared with operated/non-operated %age ratios, there was a statistically significant difference in favour of the biofeedback group (p < 0.05). CONCLUSIONS: Our results showed that EMG-B was an effective treatment modality in improving quadriceps muscle strength after arthroscopic meniscectomy surgery.
