University Hospitals Coventry and Warwickshire (UHCW) recently conducted a study, now published in The Bone and Joint Journal, that has recommended an alternative method of relief for patients undergoing knee replacement surgery. A traditional option for pain relief during knee replacement surgery is a 'femoral nerve block', a single dose of local anaesthetic injected around the femoral nerve in the groin, which is typically administered by an anaesthetist. However, a newer alternative approach uses an injection of anaesthetic agents around the knee joint and is administered by the surgeon without the need for specialist equipment. Unlike a femoral nerve block, this procedure does not require morphine after surgery as it can cause serious side effects in postoperative patients. Also, there is no need for specialist equipment like ultrasound. This is therefore likely to save surgeons and anaesthetists valuable time and resources and improve patient care.
