“…A portion of data from these patients at an earlier follow-up period has been previously reported. 35,36 An additional 167 patients were originally enrolled in the multicenter study for which the presented data were collected; however, the minimum patient enrollment was not reached at 4 investigational sites. Thus, these sites were excluded from study participation prior to reaching the minimum required follow-up, and these cases are not included in the current study group.…”

Total knee arthroplasty (TKA) is a cost-effective procedure used to treat degenerative knee disease with excellent long-term outcomes. However, TKA has not always resulted in excellent functional and patient satisfaction outcomes, partly due to the use of prostheses that did not reproduce natural knee kinematics. Due to a paucity of reports on single-radius designs, the authors evaluated the clinical and patient-reported outcomes of primary TKA in patients who had received a single-radius prosthesis. A total of 287 TKAs from 7 centers were prospectively evaluated. Mean follow-up was 5 years, with each patient undergoing year re-evaluation. Kaplan-Meier implant survivorship was 99.7% at a final follow-up of 7 years. The total reoperation rate was 1.4%. Clinical outcomes demonstrated significant improvements in Knee Society, Short Form 36, and activity scores at a mean follow-up of 5 years. The authors believe that various features of this prosthesis may have contributed to these excellent outcomes. Further longer-term studies are necessary to better evaluate these outcomes.

“…TKA is not only a successful and cost-effective treatment option for improving pain and function in patients with arthritis but it also improves the overall quality of life. 3 4 5 6 The primary focus of clinical outcomes had been based on implant longevity and objective outcomes such as range of motion, knee stability, and radiographic results. However, patient satisfaction and pain relief gained, is of utmost importance in evaluating the improvement of quality of life by a joint arthroplasty.…”

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.

“…Whether one or both knees have been replaced was not considered in several studies reporting function following TKA and where bilateral TKAs typically were treated as separate cases in the statistical analyses [18,19,33,47,52]. This method of analysis inherently violates the principle of independent samples, a key assumption for parametric tests in statistical analyses [43,59].…”
