We report on 83 patients (116 knees) who had Miller-Galante total knee arthroplasties. Thirty one knees had rheumatoid arthritis and 85 had osteoarthritis. Repeat surgery was performed in 6 knees (0.52%) due to postoperative complications. Five knees used the MG I type (0.6%) prosthesis and one knee used the MG II type prosthesis (0.3%).The causes necessitating secondary surgery were chronic hydrarthrosis in one knee, varus flail joint in one knee, patellar luxation in two knees, patellar component failure in one knee and patellar tendon rupture in one knee.In four of six knees, complications were caused by a disorder of the extensor mechanism. Four complications may have been prevented by proper alignment and soft tissue balance, precise operative technique and careful post operative treatment.
