case_images: Increased intermalleolar distance, indicating asymmetry (Fig. 1).
case_images: Pre-operative X-ray showing osteoarthritis right knee on anterior-posterior, lateral view.

case_images: X-rays of the right knee were taken from the anterior-posterior (A/P) and lateral views (Fig. 2). Pre-operative X-ray (Fig. 2) findings, including both A/P and lateral views, revealed significant degenerative changes.
case_images: (a) Draping and (b) per operative joint exposure.

case_images: TKR was executed under a subarachnoid block and with strict aseptic precautions (Fig. 3a). Arthrotomy was performed just medial to the patellar tendon (Fig. 3b).
case_images: Medial release.

case_images: Following the medial release, the patella was dislocated laterally (Fig. 4).
case_images: (a) Tibial jig fixation and (b) femoral jig fixation.

case_images: Precise bony cut was performed on the lower femoral and upper tibial surfaces, guided by proper measurements using a suitable valgus guide and jig fixation (Fig. 5, Fig. 6).
case_images: (a) Femoral component replacement, (b) tibial base plate with polythene replacement, and c) final implantation and cementation.

case_images: The tibial base plate size was carefully selected so it aligned with the anterolateral tibial border and the appropriate knee prosthesis size was carefully chosen (Fig. 7). Finally, the appropriate knee prosthesis was carefully placed (Fig. 7).
case_images: Post-operative X-ray of right knee joint replacement anterior-posterior and lateral view (a) at 1 day and (b) after 12 months.

case_images: Furthermore, post-operative X-rays of the right knee acquired from both A/P and lateral views revealed that the mechanical axis was maintained and there was no loosening of the implant (Fig. 8), confirming the successful outcome of the procedure.
