Musculoskeletal disorders are the second leading cause of years lived with disability globally. Total knee replacement (TKR) offers patients with advanced arthritis relief from pain and the opportunity to return to physical activity. We investigated the impact of TKR on physical activity for patients in a developing nation.
As part of the Operation Walk Boston surgical mission program, we interviewed 18 Dominican patients (78% women) who received TKR about their level of physical activity after surgery. Qualitative interviews were conducted in Spanish, and English transcripts were analyzed using content analysis.
Most patients found that TKR increased their participation in physical activities in several life domains, such as occupational or social pursuits. Some patients limited their own physical activities due to uncertainty about medically appropriate levels of joint use and postoperative physical activity. Many patients noted positive effects of TKR on mood and mental health. For most patients in the study, religion offered a framework for understanding their receipt of and experience with TKR.
Our findings underscore the potential of TKR to permit patients in the developing world to return to physical activities. This research also demonstrates the influence of patients' education, culture, and religion on patients' return to physical activity. As the global burden of musculoskeletal disease increases, it is important to characterize the impact of activity limitation on patients' lives in diverse settings and the potential for surgical intervention to ease the burden of chronic arthritis.
