Osteoarthritis of knee joint is a common disease affecting mostly elderly population and some younger individuals causing a painful joint limited
by mobility, deformity and functional capabilities. Total Knee Arthroplasty is an excellent modality for treating painful severe osteoarthritis of
knee providing the patient with pain relief, correcting joint instability and deformity and improving the functional capabilities of the patients which
is assessed using knee society score. This is a prospective study including 20 patients of both sexes having severe painful osteoarthritis of knee
joint. 14 patients underwent unilateral TKA and 6 patients underwent bilateral TKA. The functional outcome of total of 26 TKA were assessed. Out
of 20 study subjects, 12(60%) were male and 08(40%) were females and the mean age was 57.35years and mean follow up period was
12.46months. The mean score of part A of knee society score before surgery was 42.08 and at nal follow up it increased to 90.92 and the mean
score of part B of knee society score was 37.5 before surgery and it increased to 93.08 at nal follow up suggesting improvement from poor at preoperative period to excellent at nal follow up. This study showed that all patients achieved excellent early results with total knee arthroplasty. This
study is limited by small sample size and short follow up.
