What you should be doing after a joint replacement

Joint replacement surgeries, such as total hip arthroplasty (THA) and total knee arthroplasty (TKA), have revolutionised the management of chronic joint conditions like osteoarthritis. While these procedures offer considerable pain relief and improved mobility, the success of joint replacements heavily depends on post-operative care, particularly exercise rehabilitation. Evidence shows that an individualised and progressive exercise programme plays a crucial role in optimising joint function, promoting faster recovery, and enhancing long-term outcomes following joint replacement surgery.

Restoring Range of Motion

Postoperative exercise rehabilitation is designed to restore and maintain the joint's range of motion (ROM). Early mobilisation exercises, under the guidance of a physical therapist, help prevent joint stiffness and contractures, which can occur after joint replacement surgery. A systematic review and meta-analysis published in the Journal of Orthopaedic Surgery and Research demonstrated that supervised exercises and continuous passive motion (CPM) devices significantly improved ROM after THA and TKA. Patients who engaged in early and consistent exercises exhibited better joint flexibility and a reduced risk of postoperative complications.

Strengthening Muscles and Joint Stability

Joint replacement patients often experience muscle weakness due to pre-operative pain and limited mobility. Exercise rehabilitation focuses on strengthening the surrounding muscles to stabilise the new joint and improve functional outcomes. A study published in the Journal of Bone and Joint Surgery revealed that progressive resistance training after THA significantly increased muscle strength and overall functional capacity, leading to enhanced daily activities and better joint stability.

Pain Reduction and Improved Functionality

Evidence suggests that exercise rehabilitation can effectively reduce post-operative pain and enhance functional outcomes. A systematic review published in the Journal of Arthroplasty found that structured exercise programs, such as aquatic therapy and supervised land-based exercises, contributed to decreased pain levels and improved functional capacity in joint replacement patients. These improvements allowed patients to resume activities of daily living, leading to better overall quality of life.

Preventing Complications

Exercise rehabilitation plays a critical role in reducing the risk of complications following joint replacement surgery. Deep vein thrombosis (DVT) and pulmonary embolism are potential complications associated with joint replacement procedures. A study published in the Journal of Bone and Joint Surgery demonstrated that early ambulation and exercise significantly reduced the incidence of DVT in joint replacement patients. Additionally, exercise aids in maintaining cardiovascular health, which is essential for overall postoperative recovery.

Enhancing Long-Term Implant Survival

Long-term implant survival is a vital consideration in joint replacement surgeries. Regular exercise and proper rehabilitation have been associated with better implant longevity and overall outcomes. A meta-analysis published in the Journal of Arthroplasty indicated that adherence to a structured exercise program following joint replacement was associated with lower revision rates and improved long-term implant survival.

Exercise rehabilitation is a fundamental component of post-operative care after joint replacement surgery. The evidence overwhelmingly supports the importance of tailored exercise programmes in restoring joint function, reducing pain, preventing complications, and enhancing long-term implant survival. Early and consistent engagement in rehabilitation exercises, under the supervision of a qualified physical therapist, significantly contributes to successful joint replacement outcomes and improved quality of life for patients. Healthcare providers and patients alike must recognise the pivotal role of exercise rehabilitation in the overall success of joint replacement surgeries and work collaboratively to ensure optimal post-operative recovery.
