Comparison of functional outcome at three month follow up using knee society score in patients undergoing total knee replacement by ERP and non ERP

Background: Comparison of functional outcome at three month follow up using knee society score in patients undergoing total knee replacement by ERP and Non ERP.Methods: In this prospective study of 29 patients in group (II) who underwent total knee arthroplasty using Enhanced recovery protocol and compared with 29 patients in control group (I) whose data was obtained from hospital database in Lilavati Hospital & Research Centre, Mumbai.Results: The majority of the patients were from the age group of 61-70 years in both group I & II. There was female predominance in our study. The mean length of stay for group I was 5.69 days and for group II 3.28 days. The average knee clinical score in group I was pre op 33.52 which improved to an average post-op score of 82.62 at 3 months and for group II it improved from 34.21 to 84.66 at 3 months. The average pre-op knee functional score was 43.28 which improved to an average post-op score of 85.00 at 3 months in study group II. The average pre-op Knee Society Score was 77.14 which improved to an average post-op score of 169.66 at 3 months follow up for group II.Conclusions: The results of the present study showed that patients who underwent TKA using ERP protocol has reduced length of stay in hospital, significantly improved KSS proving TKA as an effective procedure that is associated with substantial functional improvement
