Reconstruction of soft tissues and preservation of the extensor mechanism integrity provide a major challenge following resection of the proximal tibia tumours. We propose a novel surgical technique for neopatellar ligament reconstruction using hamstring tendon in proximal tibia tumour cases. This study details the surgical technique, early clinical and radiological outcomes, and the potential long-term benefits of this innovative reconstructive approach following proximal tibia megaprosthesis implantation. This study included 15 patients with proximal tibia tumours treated at orthopaedic oncology unit in Gujarat Cancer and Research Institue (GCRI), Ahmedabad, India. 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). The tension in the tendons was optimized and the sutures were tightened with the knee in full extension and the implant with neopatellar ligament were covered by medial gastrocnemius muscle flap. The mean follow-up period was 19 months (13 to 24), the mean age of the study group was 24.6 years (14 to 44), and it included 11 males and four females.Aims

Surgical limb sparing for knee-bearing paediatric bone sarcoma is considered to have a clinically significant influence on postoperative function due to complications and leg-length discrepancies. However, researchers have not fully evaluated the long-term postoperative functional outcomes. Therefore, in this study, we aimed to elucidate the risk factors and long-term functional prognosis associated with paediatric limb-sparing surgery. We reviewed 40 patients aged under 14 years who underwent limb-sparing surgery for knee bone sarcoma (15 cases in the proximal tibia and 25 in the distal femur) between January 2000 and December 2013, and were followed up for a minimum of five years. A total of 35 patients underwent reconstruction using artificial materials, and five underwent biological reconstruction. We evaluated the patients’ postoperative complications, survival rate of reconstruction material, and limb, limb function, and leg-length discrepancy at the final follow-up, as well as the risk factors for each.Aims
