Liu Y, Wu C, Chen C, Zhang L, Xing G, Wu K, Zhao Z, Yin H, Ma Y. Impact of soft tissue around the knee on the efficacy of extracorporeal shockwave therapy in knee osteoarthritis. Medicine (Baltimore). 2022 Dec 16;101(50):e32334.
Retrospective clinical study Methods:
- In order to explore the relationship between the distribution of tissue around the knee joint and the clinical efficacy of ESWT in the treatment of KOA, 123 patients were grouped according to their body mass index (BMI). Proportions of soft tissue around the knee were measured with X-ray. - Subjects received Chattanooga Intelect RPW treatment 1x per week for 8 weeks. - The correlation between the distribution of tissue, pain, and functional improvement was analysed. Results - All the patients showed a significant reduction in pain after treatment compared to that before treatment (P < .01). - VAS (pain), Lequesne (disability) and WOMAC (function) indexes of the ‘overweight and above BMI’ group improved to a greater extent than that of the ‘normal or below normal’ BMI group (P < .01) after the intervention.
Key message: RSW treatment significantly improved symptoms, and the more abundant the soft tissue around the knee joint, the greater the degree to which RSW relieved knee pain and improved function.
