We report early results after the resection of proximal tibial rumours foll
owed by reconstruction using a modular prosthesis. The indication for wide
resection was a malignant tumour in 13 patients, and a neglected giant cell
tumour in 2. There were no mechanical failures during an average follow-up
of 3.5 years. However, there were 5 peroneal nerve palsies, 1 complete sci
atic nerve palsy, 1 vascular injury leading to an above knee amputation, an
d 2 deep prosthetic infections. There were 2 superficial skin necroses and
1 fracture proximal to the femoral prosthetic component. The mean post-oper
ative Musculo-Skeletal Tumour Society (MSTS) score in 12 patients who still
had their prosthesis in situ was 18.3 out of a possible total of 30 (range
: 10-28). Limb salvage surgery in the proximal tibia has a high early compl
ication rate even with the use of modern implants and improved techniques.
