Kneecap resurfacing during knee replacement should be the standard procedure, new study finds

Description

Researchers from the University of Oxford and the University of Aberdeen followed more than 1,700 patients for 20 years as part of the KAT (Knee Arthroplasty Trial) study, making it the longest randomised controlled trial ever conducted in knee orthopaedics.

Professor Marion Campbell from the University of Aberdeen said: ‘The results provide robust evidence to support more consistent use of kneecap resurfacing in knee replacement surgery and could help reduce variation in surgical practice, particularly given the large number of procedures carried out each year across the NHS.’
