Research summary
A unicompartmental (partial) knee arthroplasty (UKA) is the removal of one part of the knee joint, that has become damaged due to arthritis, and replacing it with an artificial implant. The placement of these implants is important because they can impact overall knee function and the wear and tear of the implant.
UKA is commonly performed without the use of robotic assistance, using typical instruments and the surgeon’s manual expertise. It can also be completed with help of a robotic surgical system which can aid in the implant placement. Both treatments are routinely used and are believed to be equally good.In order to find out which technique is better and to obtain data on the 10 year performance of the Smith+ Nephew Journey II unicompartmental knee, we are inviting patients to take part in a research project, in which some patients will have their surgery completed with Smith and Nephew’s Robotic Surgical Systems and some with typical manual surgery to compared outcomes for both patient groups.
280 patients will be invited to participate from multiple centres across the UK. Eligible patients, who have given informed consent, will be randomly allocated to either group pre-surgery. After surgery they will be monitored as an in-patient until they are medically fit to be discharged home as per routine care. The patients will be invited to have their knee examined, to have x-rays, to complete a series of questionnaires and some walking tests to assess ease of movement before discharge, and following discharge, at 6 weeks, 6 months, and 1, 2, 5 and 10 years post surgery.REC name
