Five year review of the Rotaglide total knee arthroplasty.
In this study we present the outcome for patients with the Rotaglide mobile meniscal knee prosthesis implanted for osteoarthritis. All patients reviewed had this prosthesis implanted as a primary total knee Arthroplasty in Crosshouse Hospital. The minimum follow-up period was 5 years (range 5-8.2). Patients were assessed clinically by the junior author (C.W.) and results were standardised using the Hospital for Specialist Surgery (HSS) knee score. Standard radiographs were taken in antero-posterior and lateral planes to assess for loosening using the Knee Society roentgenographic system. Case notes were then examined for evidence of peri and post-operative problems. Sixty-seven patients (71 knees) were reviewed. Ninety-four percent of patients had an excellent clinical outcome with HSS scores of 85 or more. Two knees were revised, one for meniscal fracture and one for meniscal dislocation. Both of these failures were early in our series and in a total of 312 knees to date there have been no other meniscal failures. No knees were revised for aseptic loosening and there have been no deep infections. We feel this prosthesis offers a safe and effective treatment for osteoarthritis with a good clinical outcome at 5 years with a low level of complications.
