A clinical trial has explored pre-surgery exercise conditioning as a novel approach to improving outcomes following total knee replacement.
Total knee arthroplasty (TKA) or total knee replacement (TKR) is a common orthopedic surgery that involves replacing the articular surfaces of the knee joint with smooth metal and highly cross-linked polyethylene plastic. The main aim of this surgery is to improve the quality of life of patients with severe osteoarthritis by reducing pain and increasing functional mobility.
Traditional strategies for prehabilitation and rehabilitation associated with total knee replacement surgery have focused on improving joint range of motion and function with less emphasis on neuromuscular performance. Furthermore, the standard pre-surgery exercise plans are too long and generic in effect to be considered suitable for routine clinical practice.
Recently, a new prehabilitative protocol, known as acute prehabilitative neuromuscular exercise-conditioning (APNEC), has been introduced for TKA patients.
Clinical Trial
The clinical trial investigated the effects of APNEC on physical function and muscle strength in patients undergoing TKA. The trial involved 29 patients who were randomly assigned to either a prehabilitation group or a control group. The prehabilitation group participated in a 1-week neuromuscular exercise program prior to their TKA surgery, while the control group did not receive any prehabilitation.The APNEC group received nine stressful exercise-conditioning sessions for the knee extensors of the surgery leg, done over one week. Prescribed exercise stress ranged between 60%—100% of the participant’s daily voluntary strength capacity. The primary outcomes were muscle activation capacity and muscle strength.
