Efficacy observative of proprioception training on rehabilitation therapy of knee joint function after minimally invasive surgery of patellar fracture / 中国综合临床

ABSTRACT

Objective To explore the clinical effect of proprioceptive training on knee joint function rehabilitation after minimally invasive surgery for patellar fracture.Methods Fifty-eight patients with minimally invasive Kirschner wire tension band internal fixation under arthroscopy in department of orthopedics,Peking Union Medical College Hospital of Chinese Academy of Medical Sciences from March 2016 to April 2018 were selected as research objects,and were divided into experimental group and conventional group according to digital lottery,Twenty-nine cases in each group.The conventional group received conventional rehabilitation therapy such as joint range of motion (ROM) training,joint mobilization technique,muscle strength training,weight-bearing standing and ambulation training,The experimental group added proprioception training on the basis of the conventional group.The affected knee active range of motion (AROM),Lysholm knee scoring scale (LKSS),Berg balance scale (BBS) score and modified Barthel index (MBI) score before treatment and after 2 months of treatment between the two groups were observed and compared.According to the LKSS scoring system,the effect of knee function rehabilitation was evaluated.Results After 2 months of treatment,the active range of motion of the knee joint in the experimental group ((120.3± 17.1) °) was better than that in the conventional group ((100.4± 17.5) °),with significant difference (t =4.380,P =0.000);the LYSHOLM knee joint function score in the experimental group ((93.2 ± 5.3) points) was higher than that in the conventional group ((80.6 ± 7.7) points),with significant difference (t=7.259,P=0.000);the score of BERG balance scale ((52.4±1.6) points vs.(43.7±2.8)points),the difference was significant (t =14.528,P =0.000);the score of improved BARTHEL index ((92.5± 3.1) points vs.(85.6± 2.2) points),the difference was significant (t =9.775,P=0.000).The excellent and good rate of knee joint function in the experimental group was 93.10％ (27/29),which was significantly higher than 72.41％ (21/29) in the conventional group.There was significant difference between the two groups (Z =-2.390,P =0.017).Conclusion The proprioceptive training has a remarkable effect on knee joint function rehabilitation after minimally invasive surgery for patellar fracture.It can significantly improve the range of motion,joint stability and motion control ability of the affected knee,and improve the daily living ability of the patients.
