Summary:Background Total knee arthroplasty (TKA) has been proved to be a successful and cost-effective treatment for improving pain and function in patients with knee arthritis. Total knee arthroplasty (TKA) is one of the most common orthopaedic surgeries performed worldwide and advancement in surgical techniques and prosthetic designs have improved the patient outcomes. However, concerns and priorities of patients and surgeons relating to joint replacement may differ Materials and Methods 306 TKAs in 223 patients were evaluated for functional outcome using surgeon reported American Knee Society Knee Score (KS)/Functional Score (FS) and patient-reported Oxford Knee Score (OKS). We have also assessed the correlation between FS and OKS at midterm follow up Results The mean preoperative KS, FS, and OKS in 223 patients were 42.76, 42.4, and 38.84 and the midterm mean KS, FS, and OKS were 84.29, 73.40, and 30.26, respectively. There was a statistically significant improvement in the KS, FS, and OKS at midterm follow up in Category A (CAT A) (bilateral TKA or unilateral with asymptomatic contralateral knee), CAT B (unilateral TKA with symptomatic other knee) and CAT C (inflammatory arthritis). Overall, the correlation between the midterm FS and OKS was fair. However, in CAT A and CAT B, there was no significant correlation between FS and OKS, but CAT C had a strong correlation. There was a statistically significant improvement in the KS, FS, and OKS when midterm follow up scores were compared with preoperative scores. However, no significant correlation between the American knee society FS and OKS in osteoarthritic patients at midterm follow up signifies acceptable outcome may vary between patients and physicians Conclusion All patients should be counseled preoperatively to assess their expectations and sensitize them to information regarding the expected functional outcome following TKA in their cultural context
