We wished to compare the clinical outcome, as assessed by questionnaires
and the rate of complications, in total knee arthroplasty (TKA)
undertaken with patient-matched positioning guides (PMPGs) or conventional
instruments. A total of 180 patients (74 men, 106 women; mean age 67 years)
were included in a multicentre, adequately powered, double-blind,
randomised controlled trial. The mean follow-up was 44 months (24
to 57).Aims
