All TKAs were cemented and cruciate retaining. The mean follow-up period was 3.2(2 to 4) years. All the patients had symptomatic and debilitating unilateral or bilateral osteoarthritis for which all conservative and non-surgical treatments were failed, thus preoperatively the patients had poor functionality. All patients were asked to complete Forgotten Joint Score(FJS) and Oxford Knee Score(OKS) questionnaires. The patients were matched according to age, gender, year of surgery, Kellgren-Lawrence score and pre- andpostoperative overall knee alignment. The FJS and OKS questionnaire results of the two groups were then compared. RESULTS: A mixed-effects model was used to analyze differences between SBTKA and UTKA. OKS: The mean difference in the OKS between the patients who had undergone SBTKA and those who had undergone UTKA was 1.5, which was not statistically significant(CI =-0.9:4.0, P-value = 0.228). The mean OKS of the SBTKA patients was 37.6(SD = 9.0), and the mean OKS of the UTKA patients was 36.1(SD = 9.9). FJS: The mean difference in the FJS between the patients who had undergone SBTKA and those who had undergone UTKA was 2.3, which was not statistically significant(CI =-6.2:10.8, P-value = 0.593). The mean FJS of the SBTKA patients was 59.9(SD = 27.5), and the mean FJS of the UTKA patients was 57.5(SD = 28.8). CONCLUSION: SBTKA and UTKA patients exhibited similar joint functionality and knee awareness. Our results support the use of SBTKA in selected patients suffering from clinically symptomatic bilateral osteoarthritis.展开更多
