Abstract :

Background: Total knee Arthroplasty (TKA) is a procedure in which the damaged cartilage in the knee is replaced with artificial be� surfaces. It is one of the most clinically successful and cost effective medical procedures developed during the last century but safety aspect needs to be addressed appropriately. Objective: To assess safety of bilateral total knee arthroplasty in single sitting Material and Methods: This ambispective observational study was carried in tertiary care teaching hospital in Pune city of Maharashtra state, India. All patients underwent standard preoperative workup. Those patients deemed fit to undergo total knee replacement in single sitting were included in the study. The patients with adequate pulmonary and cardiac reserve were declared fit to undergo SBTKA . For safety analysis local complications related to the wound and operative site and systemic complications related to patient�s co-morbidity and systemic status were analysed. Statistical Analysis: Mean, standard deviation, percentages and proportions were used for descriptive statistics. Results: Total 52 patients underwent Simultaneous bilateral total knee arthroplasty (SBTKA) for both knees . The study included 14 men and 38 women (1:3) , mean age was 63 � 7 years old (48–75). either with diagnosis as Osteoarthritis (83%) or Rheumatoid arthritis (17%). Infection was seen in 2 patients (4%). 2 patients (4%) complained of anterior knee pain which was persistent even with analgesics, of which one was diagnosed as post op infection. There was one death . This patient was morbidly obese, operated for SBTKA for RA both knees, who on preop evaluation was moderate risk. One patient had persistent inflammatory effusion over the operated knee which delayed the functional recovery and prolonged the stay. There were 5 patients having temperature > 1000 F for > 48 hrs. (10%). GI & urinary problems were seen in 11 patients (21%). Urinary catheterization for > 24 hrs. was required in 5 patients (10%). Urinary tract infection was seen in 2 patients (4%). 2 patients had post op ileus (4%). Post op confusion was seen in 6 patients (12%), which were observed in ICU for electrolyte imbalance and hypovolemia. Conclusion: Larger studies needed to be carried out to determine the safety of bilateral knee joint replacement Total knee Arthroplasty in single setting for more conclusive evidence.
