Abstract
Aims: 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 2 years (range 2–8.2).
Method: Patients were assessed clinically by the junior author (CW) and results were standardised using the Hospital for Specialist Surgery (HSS) knee score. Complications were quantified from patient history and examination of the case notes.
Results: Two hundred and two knees were reviewed. The results were then consolidated into groups with a minimum follow up of 2,3,4 and 5 years. The average HSS score was consistent at 91 for all four groups. Complications were also consistent ranging between 10 and 11% in all groups. These are summarised in Tables 1–4 below. The commonest complication was superficial wound infection (4.95%). There were also three deep infections (1.49%) and two revisions due to meniscal failure (0.99%).
Conclusions: These results suggest the Rotaglide total knee Arthroplasty offers safe and effective treatment for osteoarthritis with constantly good clinical results at 2–5 years follow up. The complication rate was also consistent over this period with a low incidence of meniscal failure and deep infection. There have been no failures due to aseptic loosening in this group to date.
