Abstract
Then SMILES (Stanmore Modular International Limb Salvage System) was first introduced in 1991 for use as a customized prosthesis in the treatment of malignant and aggressive bone tumours. However, the use of this pros-thesis has been extended to minimal customization, to be used in a situation of salvage surgery for the arthrosplasty, which has already undergone previous revision surgery. Between 1991 and 1997 32 SMILES prostheses were used in thismanner in 30 patients. 28 patients were available for review, all had a minimum of 3 years follow-up. The mean number of previous revision procedures was 2 and 6, average 2.6. There were 11 male and 19 female patients. The mean age at the time of the salvage procedure was 67 years (46 to 86). The mean age of the primary procedure was 57.8 (Range 43–71). The Knee Society score increased from 26 to 68 and the function score increase from 26 and 68 and the function score increased from 27 to 75. Average flexion improved post-operatively from 78 to 88 degrees. 84% of patients stated that they were pleased with the results in terms of pain and mobility.
We conclude that this prosthesis is a satisfactory alternative to complex reconstructions or amputation in the presence of infection, severe bone or soft tissue loss and has rendered acceptable results.
