The Correlation between an Objective Classification of Gait Function Pre and Post-total Knee Replacement in Two Cohorts of Individuals with Knee Osteoarthritis
Description
The presentation by Marina De Vecchis from Cardiff University focuses on a study examining gait function before and one year after Total Knee Replacement (TKR) surgery for patients with severe knee osteoarthritis. The study aims to fill a gap in existing research, which primarily explores patient-reported outcomes and satisfaction, by instead analyzing objectively measured gait data. Two cohorts, one from Cardiff University and the other from Karolinska University Hospital in Sweden, participated in the research where 3D gait analysis was performed on both healthy participants and patients at various stages of surgery.
The analysis involved extracting 24 gait variables and applying principal component analysis to classify gait function using the Cardiff classifier. The results indicated a correlation between preoperative gait function and postoperative recovery, with significant improvements observed in both cohorts. However, the study highlighted that those with more compromised gait function pre-surgery had poorer outcomes post-surgery, suggesting that delaying surgery when gait function is severely affected could influence recovery. Additionally, engaging in a larger cohort in future research is recommended to better understand variability in outcomes and patient expectations.
