Objective: Kinesio taping (R) (KT) is a widely used treatment method in musculoskeletal rehabilitation. Little is known about the KT treatment and hip strength in patients with anterior cruciate ligament reconstruction (ACLR). The purpose of this study was to investigate the effectiveness of the KT treatment on hip muscle weakness in early rehabilitation of ACLR and the possible determinants of the ACLR-hip strength deficit (HSD). Design: Double-blind sham-controlled study. Setting: Rehabilitation department. Patients: A total of 26 male patients who underwent unilateral ACLR using hamstring autograft or allograft 4 days before. Interventions: The patients were randomized to receive the knee KT treatment (n = 13) with lymphatic correction plus muscle (biceps/rectus femoris) facilitation or sham KT (n = 13) for 10 days. In addition, the same ACLR rehabilitation program was applied to all the patients. Main Outcome Measures: The baseline data included demographic and clinical characteristics, postoperative swelling, knee motion loss and knee pain, and bilateral strength of the knee and hip muscle groups, except for rotator. Then, percentage values of hip HSD and knee strength limb symmetry index were calculated. The hip strength measurements in ACLR-operated leg were repeated on the 5th to 10th days of KT. Results: Changes in all hip strength values over time were significant in both groups (P < .01). In intergroup analysis of 5th and 10th days, improvements in the flexor (only 10th day), extensor, and adductor hip strength on operated leg were in favor of KT group (P < .05). In addition, the postoperative thigh swelling and knee strength limb symmetry index values were correlated with the HSD outcomes in baseline data (P < .05). Conclusions: ACLR-HSD can be caused by postoperative increased swelling and reduced knee strength. The KT treatment with lymphatic correction and muscle facilitation can be used in the treatment of postoperative hip muscle weakness after ACLR.
