The study on efficiency of knee brace after arthroscopic anterior cruciate ligament reconstruction
Main Article Content
Abstract
Objectives : Compared muscle strength and range of motion between knee brace and no knee brace after arthroscopic anterior cruciate ligament reconstruction.
Materials and Methods : This study was retrospective descriptive study. In patients who had arthroscopic anterior cruciate ligament reconstruction at Charoen Krung Pracharak Hospital and participated in a continuous rehabilitation program for 3 months. We collected data from october 2015 to september 2020. Outcome measures included muscle strength and range of motion patients were assessed preoperatively, then 3 months postoperatively. The results were analyzed using descriptive statistics presented by percentage, mean, standard deviation, median and interquartile range. The analytical statistic is Independent T-test or Mann-whitney U-test statistic, chi-square test and Fisher exact test.
Results : A total of 46 patients. 36 male (78.3%) and 10 female (21.7%) patients. The patients were divided into 2 groups: knee brace group (23 patients) and no knee brace group (23 patients). The results were as follow : Range of motion knee extension (Median(IQR) knee brace group 1(0,5) no knee brace group 1(0,3) degree) Range of motion knee flexion (Median(IQR) knee brace group 130(125,132) no knee brace group 131(129,135) degree) Quadriceps muscle strength (knee brace group 105.16±29.15 and no knee brace group 106.37±45.75 N·m) Hamstring muscle strength (knee brace group 63.86±16.21 and no knee brace group 60.51±21.99 N·m) And the ratio between the strength of the quadriceps muscle and the hamstring muscle (knee brace group 63.49±17.78% and no knee brace group 60.26±16.68%) We discovered a statistically not significant difference between knee brace group and no knee brace group at the 0.05 level.
Conclusion : Knee brace or no knee brace anterior cruciate ligament surgery does not affect the range of motion and strength of the leg muscles. The two groups had no difference in treatment results. This can be applied and given advice on caring for patients after surgery., but external factors should be considered, such as age, gender, comorbidities, treatment, differences in equipment Using the device and following the instructions as well.
