Abstract:
[Objective]To refine operative indications of rotating hinge prostheses and report the medium term results of these implants,and to analyze the reasons for postoperative complications.[Method]From 1999 to 2007,42 Endo-Model(Link) rotating hinge prostheses were used in 34 patients.The cases were all gonarthrosis with severe genu varus,genu valgus or flexion contracture.Bone defect or instability was found in these cases before operation.The mean follow-up was 6.4 years(2.3-10.4 years).[Result]One case of deep infection,and one periprosthetic fracture were noted.And 3 cases of patella subluxation or tilt were detected by postoperative X-ray.All patients had excellent pain relief and restoration of walking capability.The average HSS score improved from 40.5 points to 89 points after surgery.[Conclusion]Besides being used in revision surgery,rotating hinge prostheses are indicated in primary arthroplasties for patients with severe ligament laxity,substantial deformity or bone losses.With appropriate indication selection and accurate operative skill,satisfactory medium term result can be obtained.
