Abstract:
[Objective]To investigate the indications,complications and mid-term results of total knee arthroplasties using rotating hinge knee prosthesis. [Methods]Thirty total knee arthroplasties using rotating hinge prosthesis were performed in twenty-eight patients from July 1998 to July 2008.Seven patients were male and twenty-one patients were female.The average age was 62 years(42-75 years).The diagnosis included osteoarthritis in 8 patients,rheumatoid arthritis in 2 patients,traumatic arthritis in 3 patients,Paget's disease patient,serious genu valgum in 7 patients and 10 failure TKAs.All patients were followed up for 12 to 120 months.The patients were evaluated according to knee score system and the complications were observed.[Results]The pain was relieved and function was improved in all knees.The average knee pain score increased from 19.5 to 77.9,and knee function score from 22.5 to 50.5.Range of motion of knees increased from 58.4?to 72.8?.No revision was needed in all patients,The complications included anterior knee pain(8 cases),extension lag(5 cases),prosthesis broken(1 case) and patella tendon rupture(1 case).[Conclusion]The mid-term results of total knee arthroplasty using rotating hinge knee for severe knee deformity are satisfactory.Complications should be prevented carefully.
