Prevention is by neuromuscular training and core strengthening.[3][4] Treatment recommendations depend on desired level of activity.[3] In those with low levels of future activity, nonsurgical management including bracing and physiotherapy may be sufficient.[1] In those with high activity levels, surgical repair via arthroscopic anterior cruciate ligament reconstruction is often recommended.[1] This involves replacement with a tendon taken from another area of the body or from a cadaver.[4] Following surgery rehabilitation involves slowly expanding the range of motion of the joint, and strengthening the muscles around the knee.[1] Surgery, if recommended, is generally not performed until the initial inflammation from the injury has resolved.[1]
