Background: Alignment of the femoral and tibial components is a major independent indicator of implant survival. The placement of a lateralised tibial jig can increase the precision of the tibial cut. The aim of this study was to investigate whether lateralization of the lateral tibial plateau reference point influences proper coronal plane alignment of the complete knee prosthesis after surgery, based on the degree of tibia vara. Methods: This observational prospective study included 19 patients with tibia vara who were receiving primary TKA (Total Knee Arthroplasty) for osteoarthritis of the knee. The main outcomes that were assessed were the tibia vara, the postoperative tibiofemoral angle, and the degree of lateralization of the tibial plateau reference point (and its relationship to the magnitude of the tibia vara). The AKSS (American Knee Society Score) was used to measure postoperative outcomes. Results: Pre-operative tibio-femoral angle mean (SD) in degree was 17.13 ± 6.04. Post-operative tibio-femoral angle mean (SD) in degree was 5.6 ± 1.38. The difference was statistically significant (p <0.001). The pre-operative tibia vara mean (SD) in degree was 9.89 ± 5.335. Post-operative tibia vara mean (SD) in degree was 0 ± 0. The difference was statistically significant (p <0.001). There was a significant, progressive improvement in the AKSS scores during the follow-ups compared to the preoperative scores. Linear regression analysis showed a very high degree of positive correlation between the amount of lateralization of the tibial reference point and the magnitude of the tibia vara (R2 = 0.526, p = 0.003) as well as the tibio femoral angle (R2 = -.440, p = 0.015). Conclusion: Reasonable accuracy can be achieved with the use of the extramedullary jig for tibial component alignment by lateralizing the proximal tibial reference point in patients with tibia vara, as evidenced by improvements in the AKSS score postoperatively and deformity correction.
