Abstract:
We evaluated functional outcomes for patients who
underwent surgery for resection and endoprosthesis
replacement for primary tumours around the knee. We used
the Musculoskeletal Tumour Society Scoring System
(MSTS) for functional evaluations to compare differences
between distal femur (DF) and proximal tibia (PT)
placements. The study sample included 34 cases of distal
femur and 20 cases of proximal tibia endoprosthesis
replacement. Primary tumours were classified as follows: 33
osteosarcoma, 20 stage III giant cell tumour (GCT) and one
case of mesenchymal chondrosarcoma. The mean MSTS
score for both DF and PT endoprosthesis together was 21.13
(70.43%), and The MSTS scores for DF was 21.94 (73.13%)
and PT was 19.75 (65.83%) Infection developed in 7 cases
and 5 of which were PT endoprosthesis cases. Three deep
infections required early, two-stage revision and resulted in poor MSTS scores. We conclude that endoprosthesis
replacement for primary bone tumours had early good to
excellent functional outcome. There were no differences in
functional outcomes when comparing distal femur
endoprostheses with proximal tibia endoprostheses.
