Evaluation of outcome in arthritic patients undergoing total knee arthroplasty using knee society score in South Indian population-A prospective clinical study

This study aims to evaluate pre-and postoperative functional outcomes in patients with arthritis undergoing Total Knee Arthroplasty using Knee Society Score.

This study included 28 cases (30 knees) who underwent primary total knee replacement at JSS Hospital between September 2014 to May 2016. Patients were evaluated using knee society score at regular follow-up. The follow-up included immediate post-op, at 1 month, at 3months and at 6 months.

In our study, all the 30 knees had poor knee score of <60 preoperatively, postoperatively after 6 months 7 knees had an excellent score (80–100) and 16 knees with good score (70–79), 5 with fair score (60–69) and 2 with poor score (<60).

Preoperatively all patients had a poor functional score (< 60), postoperatively 15 patients had an excellent score (80–100), 4 patients with a good score (70–79), 6 patients had a fair score (60–69) and 5 patients had a poor score (<60). The KSS and FSS scores were however not significantly different after 3 and 6 months. Pre-operatively all of our patients had moderate to severe pain, post-operatively 21 knees had no pain and 21 knees had mild pain. Preoperative average Flexion of 78 degrees was increased to 106.33 degrees postoperatively.

Total Knee Arthroplasty is an excellent method for patients with knee arthritis in providing pain-free mobile joint and improving the functional ability significantly, thereby lifting their quality of life significantly.
