In this review, we present the data of one of the largest non-designer, mid- to long-term follow ups of the AGC.

We present a total of 1538 AGC knees during a 15 year period, of which 902 were followed up by postal or telephone questionnaire focused on Oxford Knee Scores, Visual analogues of function and pain and survival analyses performed. Mean length of follow up was 10.4 years.

85.7% of patients had an Oxford knee score of between 0 and 40, with 71.2% scoring between 0–30.

65.6% of patients responded with a Visual Analogue Score (VAS) of 0 or 1 at rest (minimum pain 0) and 53.9% reporting VA scores of 0 or 1 while walking.

87.5% of patients reported Excellent or good functional reports at final follow up and 90.3% reporting excellent or good pain control compared to per-operative levels.

Survival analysis confirms excellent survivorship.

This large cohort and multi-surgeon trial reproduces the excellent results as demonstrated by the designer centre (Ritter et al.). Mid to long term outcome sows excellent function and analgesia. Complication rates are low and the necessity for revision remains low.
