To establish whether the clinical results obtained with bicondylar sledge prostheses correlate with clinical findings, and whether clinical results influence gait pattern. 15 patients with bicondylar sledge prostheses were compared with healthy controls. The clinical examination was documented using the HSS, Knee Society, Tegner, and patella scores, and the Visual Analogue Scale. Gait analysis was done with a three-dimensional motion analysis system and force platforms. A comparison of patients and controls showed significant differences in the clinical results, whereas the parameters gait function, muscle force and pain did not. No significant differences were found between the operated and non-operated legs. In comparison with controls, patients showed significant differences in the ground reaction forces. The abnormal gait findings showed no correlation with clinical results, nor did such parameters as age, weight and duration of follow-up appear to have any influence. The non-operated leg adapted to the gait pattern of the operated leg, to restore gait symmetry. Subjective complaints or clinical results show little relationship to gait parameters in patients receiving a bicondylar sledge prosthesis.
