Background and objectives:
The functional results and the complications after several limb-saving and ablative treatments because of lower extremity bone sarcoma were evaluated.
Methods:
Seventy-seven surviving patients were evaluated according to the msts (american musculoskeletal tumor society) functional rating system. fifty-two patients had limb-saving and 25 had ablative therapy. median follow-up was 97 months in the limb-saving group and 112 months in the ablative group.
Results:
Functional results in the limb-saving group were significantly better than in the ablative group (p = 0.0001). functional results in patients with tumors about the knee joint were significantly better (p = 0.0064) after limb-saving surgery (i.e., endoprosthesis, knee arthrodesis, or rotationplasty) compared to functional results after ablative surgery (i.e., hip or knee disarticulation or above-the-knee amputation). complications were 3 times more common after limb-salvage procedures and 4 times more common after endoprosthetic reconstructions compared to after ablative procedures. complications after limb-saving therapy were fewest in tumors about the knee joint. in 3/28 patients, the endoprosthetic reconstruction had to be converted to an amputation.
Conclusions:
Functional results were significantly better after limb-saving compared to after ablative therapy. complications, however, were more common after limb-saving therapy.
