Abstract

Aim: The aim of the present study was to know the functional outcome of Primary TKR in Severe fixed flexion deformity of knee compared with TKR in knees without fixed flexion deformity (FFD).
Methods: This was a prospective study of the Department of Orthopaedics, Shri Shankaracharya Institute of Medical Sciences, Bhilai, Chhattisgarh, India for the period of 1 year. Patients with and without severe flexion deformity of knees underwent primary TKR. Total of 120 knees were taken for the study with 90 with FFD of more than 30 degree and 30 were without FFD which were kept as a control. This study includes both inflammatory and non-inflammatory arthritis.
Results: In 100 patients, there were 30 bilateral cases and 90 unilateral cases with a total of 120 knees. 66 knees were inflammatory arthritis and 34 with non-inflammatory arthritis. There were 45 females and 55 male patients. Average age of the patients was 59.6 years (28-75 years). Average follow up was 1.5 years (1-3 years). In Primary TKR in FFD - Average FFD was 44 degree, Pre-operative average KSS-pain score was 27.5 and functional score was 15, post operatively KSS pain score was 82.7 and function score was 79.1. In Primary TKR in no FFD - Pre-operative average KSS-pain score was 31 and functional score was 24, post operatively KSS pain score was 85.3 and function score was 80.2.
Conclusion: There was no significant difference in postoperative KSS- pain and functional score, in patients with no FFD was comparable with patients with FFD. TKA is successful in correcting flexion deformity, although the amount of correction obtained depended on the degree of preoperative flexion deformity.
