A STUDY OF THE CLINICAL OUTCOMES AND FUNCTIONAL RECOVERY FOLLOWING TOTAL KNEE ARTHROPLASTY IN PATIENTS WITH ADVANCED OSTEOARTHRITIS

Abstract

Advanced osteoarthritis of the knee is a leading cause of chronic pain, reduced mobility, and functional disability among older adults worldwide. As the disease progresses, conservative treatment options often become ineffective, making Total Knee Arthroplasty (TKA) one of the most widely recommended surgical interventions. Despite its increasing use, variations in postoperative outcomes and functional recovery remain important clinical concerns. This study aimed to evaluate the clinical outcomes and functional recovery of patients undergoing Total Knee Arthroplasty for advanced osteoarthritis. A quantitative retrospective cohort design was employed, utilizing medical records and postoperative assessment data from patients who underwent TKA in tertiary care hospitals. Clinical outcomes were assessed through pain reduction, range of motion, complication rates, and patient-reported functional scores, while recovery was measured using standardized orthopedic evaluation tools over a six- to twelve-month follow-up period. The findings revealed significant improvements in pain relief, joint mobility, walking ability, and overall quality of life following surgery. Most patients demonstrated substantial functional recovery within the first year after the procedure, with high levels of postoperative satisfaction. Factors such as early rehabilitation, adherence to physiotherapy, and absence of major complications were associated with better recovery outcomes. However, delayed rehabilitation and comorbid conditions contributed to slower functional improvement in some patients. The study concludes that Total Knee Arthroplasty is an effective treatment for advanced knee osteoarthritis, providing significant clinical and functional benefits. These findings support the continued use of TKA as a reliable intervention and highlight the importance of comprehensive postoperative rehabilitation programs to maximize patient recovery and long-term functional outcomes.
