Total Knee Arthroplasty in Young Active Patients Using a Highly Congruent Fully Mobile Prosthesis

A consecutive cohort of 63 young patients (80 knees; mean age, 50.7 years) received a Rotaglide mobile knee (Corin Ltd, Cirencester, UK) prosthesis as a primary procedure by a single UK surgeon. Mean follow-up period is 7.3 years (range, 3-12 years). Patients were assessed using the International Knee Society Score and the Oxford Knee Score. Radiolucency was assessed using the Knee Society roentgenographic system. The patients demonstrated an excellent knee and function International Knee Society Score of 98 and 93.6, respectively, with an Oxford Knee Score of 15.5. One knee was revised for traumatic dislocation of the mobile bearing. There were no revisions for aseptic loosening or deep infection. This study demonstrates encouraging midterm results for this device in a young patient cohort.
