Abstract

Objective The purpose of this study was to determine the effects of lower extremity motor control exercises on knee proprioception, muscle strength, and functional level in patients with anterior cruciate ligament reconstruction (ACL-R). Materials and Methods Thirty-two of the 57 patients with ACL-R using tibialis anterior allografts were divided into two groups. Group I: lower extremity motor control exercises were added to the standard rehabilitation program. Group II: standard rehabilitation program was applied. Effects of lower extremity motor control exercises on quadriceps and hamstring muscles strength, knee joint position sense, and hop test were evaluated. Results There were no differences in muscle strength and endurance of the quadriceps and hamstring between the operative and nonoperative sides in Group I (p > 0.05) while there were significant differences in strength of the quadriceps and hamstring between the operative and nonoperative sides in Group II (p < 0.05). There were significant differences in the endurance of the quadriceps and hamstring and knee joint position sense at 15°, 45°, and 75° between the operative sides of the patients in both groups (p < 0.05). Conclusions The neuromuscular control exercises program was found to be more effective in reducing the difference in strength while the standard program was found to be more effective in reducing the difference in endurance between the operated knee and the other knee. This study revealed that neuromuscular control exercises should also be used to improve knee proprioception sense following ACL-R.

Highlights

A successful rehabilitation program should benefit the patients to return to an active lifestyle and preinjury levels
Asymmetries in physical performance such as hopping, jumping, landing, loading, and movement pattern between the reconstructed and uninjured legs were described in the patient with anterior cruciate ligament reconstruction (ACL-R) [8, 9]. is asymmetry can be seen for several years after ACL-R surgery [9, 10], and it must be treated to protect the joints from abnormal loading, to prevent secondary injuries, and to develop correct movement patterns
To the best of our knowledge, there have been no studies evaluating the mentioned outcomes of the neuromuscular motor control exercise programs after ACL-R with tibialis anterior tendon allograft. erefore, the purpose of this study was to assess the effects of motor control exercises on muscle strength, proprioception, and functional level after ACL-R with tibialis anterior tendon allograft. e hypothesis of the present study was that nonathletic patients who had undergone a standard rehabilitation program with lower extremity motor control exercises had better outcomes compared to patients who had undergone a standard rehabilitation program

Summary

Introduction

A successful rehabilitation program should benefit the patients to return to an active lifestyle and preinjury levels. Asymmetries in physical performance such as hopping, jumping, landing, loading, and movement pattern between the reconstructed and uninjured (another side) legs were described in the patient with ACL-R [8, 9]. To the best of our knowledge, there have been no studies evaluating the mentioned outcomes of the neuromuscular motor control exercise programs after ACL-R with tibialis anterior tendon allograft. Erefore, the purpose of this study was to assess the effects of motor control exercises on muscle strength, proprioception, and functional level after ACL-R with tibialis anterior tendon allograft.
