Retrospective Study of Rehabilitation Exercise Combined with Extracorporeal Shock Wave Therapy for Knee Osteoarthritis.

Abstract

BackgroundThe aim of this study was to investigate the effect of rehabilitation exercise combined with extracorporeal shock wave therapy (ESWT) on knee osteoarthritis (KOA).Material/MethodsThe clinical data of 217 patients with KOA who underwent ESWT in our hospital from December 2017 to January 2020 were retrospectively analyzed. The patients were divided into a rehabilitation exercise (RE) group and a non-rehabilitation exercise (NRE) group according to whether they were given RE. The treatment course of the 2 groups was 5 weeks. Pain Visual Analog Scale (VSA), Western Ontario and McMaster Universities knee osteoarthritis index visualized scale (WOMAC), Lequesne index scores, Range of motion (ROM) score, and Japanese Orthopaedic Association (JOA) scores were used to evaluate the treatment effect of the 2 groups of patients.ResultsAfter 5 weeks of treatment, the VSA scores (p<0.001), WOMAC scores (P<0.001) and Lequesne index scores (P<0.001) of the RE group and NRE group were significantly lower than those before treatment, while ROM score (P<0.001) and JOA score (p=0.006) were significantly increased. Compared with the NRE group, the VAS score (3.14±0.64 vs. 4.78±0.85, P=0.002), WOMAC score (20.37±4.06 vs. 27.82±4.57, P<0.001) and Lequesne index score (6.13±1.83 vs. 7.35±2.21, P=0.019) in the RE group were significantly lower than those in the NHE group; however, the ROM score (89.13±9.83 vs. 79.15±6.25, P=0.021) and JOA score (79.53±7.59 vs. 67.85±8.27, P=0.016) were significantly higher than those in the NRE group.ConclusionsRE combined with ESWT has a positive effect on KOA, which may more significantly relieve the patient’s clinical symptoms and improve joint function and quality of life.
