Surgical procedures included resecting the proximal tibia tumour, implanting a megaprosthesis, and using hamstring tendons to reconstruct the extensor mechanism by the neopatellar ligament. Autologous hamstring tendons (gracilis and semitendinosus) harvested from the ipsilateral leg were used and these tendons were braided together with a nonabsorbable suture and threaded through the remaining patellar tendon. The braided tendons were then secured to the holes in the tibial tuberosity of the proximal tibia megaprosthesis implant XLO (Ortho Life Systems, India) using nonabsorbable fibre wire sutures FiberWire (Arthrex, USA).
