* Implant type: GMRS = Global Modular Replacement System (Stryker, Rutherford, NJ, USA); Custom = custom-made, di erent manufacturers; MUTARS = Modular Universal Tumor and Revision System (implantcast, Buxtehude, Germany); KMFTR = Kotz Modular Femur Tibia Reconstruction (Stryker, Rutherford, NJ, USA); Mod. = modular, di erent manufacturers; HMRS = Howmedica Modular Reconstruction System (Stryker, Rutherford, NJ, USA). Mean followup, unless otherwise stated (med. = median) with the range in parentheses; DF = distal femur, PT = proximal tibia, TF = total femur, EAK = extraarticular knee; prim. = primary tumor, mets. = metastatic disease, non-tum. = nontumorous; RH = rotating hinge, FH = xed hinge; unc = uncemented, cem = cemented, Pc = porous-coated; **of the patients in whom the MUTARS was implanted during primary surgery; N/R = not reported.
