Long-term Assessment of Functional Outcomes and Quality of Life in Patients Undergoing Total Knee Arthroplasty

ABSTRACT While short-term outcomes of total knee arthroplasty (TKA) have been extensively studied, there is a need for longstanding assessments to understand the enduring impact of the procedure on patient well-being. A retrospective cohort research to rate the longstanding functional outcomes and quality of life (QoL) in those undergoing primary TKA. Patient-reported outcomes, including SF-36 and EQ-5D scores, were collected at multiple time points postoperatively (1, 5, and 10 years). Objective assessments of functional parameters, i.e., range of motion, gait analysis, and quadriceps strength, were also recorded. Current findings demonstrate significant improvements in functional outcomes post-TKA, with sustained benefits observed over a 10-year period. Range of motion, gait parameters, and quadriceps strength showed consistent enhancements postoperatively. Moreover, QoL measures, as reflected by SF-36 and EQ-5D scores, exhibited substantial improvements following TKA and remained elevated throughout the follow-up period. This research highlights the enduring effectiveness of TKA in improving both functional outcomes and QoL in patients with advanced knee arthritis.
