Abstract
Objective
A study was performed in a tertiary health care centre to evaluate outcomes of arthroplasty in Indian Population. Various factors which may affect knee flexion after surgery were also evaluated.
Methods
82 patients with 60 unilateral & 22 bilateral total knee arthroplasties were included in the study. Assessment was done as per knee society knee score and function score. A simple functional questionaire including ability to squat, ability to sit cross leg, kneel while prayers, ability to use Indian toilet was filled and patients were rated accordingly as fair, good and excellent.
Results
Average improvement in knee score was from 22.88 to 91.23 and function score from 16.26 to 73.59. Average range of motion improved from 80.4 to 125 degrees. Preoperative range of motion predicted final range of motion. There was significant improvement in flexion contracture (Mean 15.3 to 1.19). There was trend of increase in range of motion with time with no further gain reported after 1 year. Age, Sex, diagnosis, BMI, tibio- femoral angle did not of affect the final outcome. A Comparison was made between total condylar prosthesis & posterior stabilized prosthesis with no significant differences of outcomes between the two. 65% were rated excellent, 30% rated good & 5% fair as per functional questionaire given to the patients.
Conclusion
Cemented total knee Arthroplasty provides pain relief, correction of deformity & restoration of function in inflammatory and degenerative arthritis. There is need to develop new functional scoring system for Indian population as knee society function score does not correspond to routine functional milestones of daily living achieved after total knee arthroplasty in Indian population.
