Abstract
Introduction & aims
Total knee Arthroplasty has revolutionized the lifestyle of patients with end stage knee arthritis. This study was conducted to describe the outcome from patient's perspective one year after TKR and patient satisfaction in terms of post operative pain and functional outcome Also, to identify preoperative characteristics predicting post operative outcome.
Method
A prospective study was conducted at our institution (Dayanand Medical College and Hospital, Ludhiana) from 2010 to 2012. The study included 104 patients (74 females and 30 males) with 152 cemented TKR surgeries. The average age of the patients was 61.39 years. Out of 104 patients, 48 had bilateral TKR, 31 had left TKR and 25 had right TKR surgery. Knee injury and osteoarthritis outcome score (KOOS) and DMCH General Patient Questionnaire was used to analyse the satisfaction level, physical activity and quality of life one year after the TKR surgery.
Results
There was significant improvement in all KOOS subscale scores but post operative sports and recreational scores remained at lowest level in the Likert scale. There was no significant effect of age, sex, duration of symptoms, co morbidities and BMI on post operative KOOS scores and patient satisfaction. There was no significant difference in post operative mean pain and functional scores in patients with higher and lower ranges of pre operative scores, though patients with higher pre operative scores had slightly higher post operative scores. The mean post operative KOOS scores had trend of higher scores in RA patients as compared to OA patients. However, there was no statiscally significant difference between these two groups. Post operative KOOS pain and activity daily living (ADL) scores were comparable to patient's satisfaction levels.
Conclusions
TKR significantly improves patient's pain symptoms, function and activities of daily living and knee related quality of life as more than 80% patients showed excellent satisfaction one year after the surgery. Sports and recreational activities did not improve to the same extent as these activities were not applicable to more than 30% of the patients.
