Hip osteoarthritis is a prevalent condition that leads to considerable disability and health-related burdens for those affected. Hip replacement surgery is performed in approximately 10% of osteoarthritis cases in Europe and Australia, leading to significant improvements in quality of life. However, the effectiveness of nonsurgical treatments, such as resistance training, remains poorly understood. To address this, the Danish Rheumatism Association sponsored a study to compare the effectiveness of resistance training with hip replacement surgery in patients with osteoarthritis.
The clinical trial included 109 patients diagnosed with severe hip osteoarthritis, with the majority (80%) using acetaminophen to manage pain, and the remaining participants using other nonsteroidal anti-inflammatory drugs or opioids. The baseline assessment using the Oxford Hip Score was approximately 25, with a score of 48 indicating the least severe disease. Participants were randomly assigned to either undergo total hip replacement surgery or attend 1-hour physiotherapy resistance training sessions twice a week for 12 weeks. After 6 months, the results showed that those who underwent hip replacement surgery experienced less disease progression than those who participated in resistance training. Specifically, the resistance training group saw a 4.5-point increase in the Oxford Hip Score, while the surgery group had a 16-point increase. The researchers acknowledged that the study was not blinded, as it is not feasible to conduct sham surgeries or sham exercises, meaning the results may be influenced by a placebo effect.
