Implant longevity, complications and functional outcome following proximal femoral arthroplasty for musculoskeletal tumors: a systematic review.

A systematic review of the literature was undertaken to evaluate the outcomes and complications following proximal femoral arthroplasty for primary or metastatic tumors affecting the proximal femur. Six hundred sixty-eight patients were available for review. The length of resection ranged from 92 to 212 mm. Limb salvage rate reached over 90%. At 5 years the implant survival rate was 84% and at 10 years, it was 70%. The overall revision rate was 11.1%. Prevalence of venous thrombo-embolic (VTE) events was 8.5%, dislocation rate was 5.8%, infection was 5.2%, local tumor reoccurrence was 4.7%, perioperative mortality was 1.5%, and periprosthetic fracture was 0.6%. Where it was provided the Musculoskeletal Tumour Score was 70.8%. The implants tend to outlive patients with metastatic disease and high-grade localized disease, providing them with a relatively pain-free limb with good mobility and quality of life.
