Abstract
In this study we intend to evaluate the outcomes 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 to 8.2). Patients were assessed clinically by the junior author (CW) and the results were standardised using the Hospital for Specialist Surgery (HSS) knee score. Standard radiographs were taken in AP and lateral planes to assess for loosening using the Knee Society roentgenographic system. Case notes were then examined for evidence of complications in the peri and postoperative complications.
Sixty-five patients (71 knees) were reviewed. There was an excellent clinical outcome with HSS scores of 85 in 97.1% of patients. Two knees (2.9%) were revised, one for meniscal fracture and one for meniscal dislocation. Both these patients also attended for review and were making good progress. Both of these failures occurred 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.
