ASSESSMENT OF FUNCTIONAL RECOVERY FOLLOWING PATELLAR RESURFACING GUIDED BY OSSEOUS ANATOMICAL LANDMARKS IN TOTAL KNEE ARTHROPLASTY PATIENTS

Objective: The present study aims at the assessment of functional outcomes of patellar resurfacing using bony anatomical landmarks in patients undergoing total knee arthroplasty (TKA). Study design: A descriptive case series study. Place and Duration: This study was conducted in, Pakistan Institute of Medical Sciences Islamabad Pakistan Hospital for period of 3 years from January 2022 to January 2025. Methodology: A descriptive case series was conducted at the department of Orthopaedics. The study involved 200 patients selected via non-probability purposive sampling. Patellar resurfacing was performed using bony landmarks, and patients were followed postoperatively. Follow-ups were biweekly for two months and monthly thereafter. Functional outcomes were classified as excellent, good, or poor. Patients also received guided knee mobilization and dynamic exercise training post-surgery. Result: The mean age of patients was 58.5 ± 7.8 years. Of the 200 patients, 33% were male and 67% female; 67% were from urban areas. The average disease duration was 4.4 ± 2.1 years; 30.6% had diabetes, 52% had hypertension, and 24% were obese. At six months, 87% showed excellent and 13% good functional outcomes. Conclusion: Patellar resurfacing guided by bony landmarks is a safe and effective technique in TKA, offering excellent functional recovery and improved quality of life. Better outcomes were linked with younger age and presence of comorbidities such as diabetes and hypertension.
