Abstract

Objective: This study aims to evaluate patient-reported outcomes and satisfaction following primary TKA in patients with osteoarthritis, specifically using four distinct brands of posterior-stabilized implants.

Methods: Conducted as a prospective study, this research assessed patient-reported functional outcomes and satisfaction after TKA with four brands of posterior-stabilized implants. The Knee Injury and Osteoarthritis Outcome Score (KOOS) and the Short Form Health Survey (SF-12) were utilized to evaluate functional outcomes pre-operatively and post-operatively at 3 mo, 6 mo and 1 y intervals. Data was summarized in Microsoft Excel and analyzed using SPSS software.

Results: The cohort consisted predominantly of patients over 60 y of age. A higher female prevalence was observed across all groups (p = 0.9389). Significant intra-group improvements in KOOS and SF-12 scores were recorded (p<0.00001), but no significant inter-group differences were found (p>0.05).

Conclusion: This study illustrates that TKA significantly improves patient-reported outcomes, as indicated by KOOS and SF-12 scores, across different implant brands. Despite notable improvements within each group, no substantial inter-group differences suggest that surgical technique and patient characteristics may play a more critical role in functional recovery and satisfaction than the specific prosthetic design. These results highlight the importance of a comprehensive approach to TKA patient management and recommend future research into the long-term effects of implant technology on recovery outcomes.
