Effects of Pre-Operative Rehabilitation Exercises on Isometric strength, Proprioception Sense, Balance and Functional Score in Combined Injuries Patients of Medial Collateral Ligament and Anterior Cruciate Ligament

Soung-Yob Rhi, Jang-kyu Lee


Aim: Although many studies have focused on rehabilitation exercise for combined injury of MCL and ACL, no comprehensive studies have investigated the use of the pre-op rehabilitation exercise in combined ligament tear patients. Therefore, the purpose of this study was to assess the effects of pre-op rehabilitation exercise(PORE) on isometric strength, knee joint of function, proprioceptive sense and balance.

Materials and Methods: Subjects 16 male, They were divided into the exercise group(EG, n=8) and a control group(CG, n=8). Eight participants were exercised with pre-op rehabilitation exercise six times per week for 4weeks. The remaining 8 participants did not receive a exercise intervention between tests and served as the control. Isometric strength(70° extension, 20° flexion) , functional score(Lysholm score), proprioception sense(error between the actual angle 15° at the knee) and balance(one-leg standing test) were measured in 16 combined injury of MCL and ACL Patients. The data were analysed using repeated-measures analysis of variance.

Result: Significant differences were observed between the two groups in EG and CG isometric strength(extension: p<0.001, flexion: p<0.008), functional score(p<0.019), proprioception sense(p<0.025), balance test(p<0.000). These results suggest that pre-op rehabilitation exercise improves lower extremity muscle power, body function, proprioceptive sense and balance.
