Abstract
In knee osteoarthritis surgery, managing postoperative wound healing and minimizing scar formation are pivotal for patient recovery and satisfaction. These aspects are particularly challenging due to the nature of the surgical procedure and patient demographics. Physiotherapy interventions are increasingly recognized for their role in improving these postoperative outcomes. This meta-analysis sought to evaluate the efficacy of physiotherapy in enhancing wound healing, as measured by REEDA scores, and reducing scar formation, as indicated by Manchester Scar Scale (MSS) scores, following knee osteoarthritis surgery. Analysing data from eight studies, we found that physiotherapy significantly improved wound healing, evidenced by lower REEDA scores (SMD = -19.58, 95% CI: [-22.49, -16.66], p < 0.01), and reduced scar formation, reflected in lower MSS scores (SMD = -24.79, 95% CI: [-30.03, -19.55], p < 0.01). These findings highlight the crucial role of physiotherapy in postoperative care for knee osteoarthritis patients, emphasizing its impact on enhancing recovery and improving surgical outcomes.
