BACKGROUND & OBJECTIVE

Total Knee Replacement (TKR and often referred to as TKA) remains one of the most common elective orthopedic surgeries worldwide. While many operative and post-operative variables influence outcome, it is important to more completely understand the pre-operative factors that impact patient outcome.

The aim of this study was to investigate the preoperative factors affecting health-related quality of life (HRQOL) at 3 and 12 months after total knee arthroplasty (TKA).

It is important to more completely understand the pre-operative factors that impact patient outcome.

Clinicians may benefit from improving familiarity with self-efficacy and choose to discuss this openly with patients.

METHODS

This study included preoperative and postoperative assessments of 156 people that underwent TKA to alleviate knee osteoarthritis (OA). Measures included the Knee Injury and Osteoarthritis Outcome Score (KOOS) as a measure of HRQOL before surgery and 3 and 12 months
