A first degree ACL injury usually requires 3 to 4 weeks of rest and recuperation.
A first degree ACL injury is a minor injury, usually with only ligament edema and no ligament tear or rupture.
In the acute stage, local rest, protection of the knee joint and avoidance of strenuous exercise are usually the main focus, and the duration of rest is related to the severity of symptoms, usually around 3 to 4 weeks. However, active rehabilitation training is also needed during the rest period to avoid adverse complications such as joint contracture and muscle atrophy.
Rehabilitation exercises that can be used during the rest period include isometric contraction of quadriceps, ankle pumping exercises, straight leg raising, and pain-free range of joint motion of the knee joint, etc. After the rest period, resistance strength exercises for the muscles around the knee joint, and lower limb stabilization and flexibility exercises are performed in order to restore the normal knee joint function.
It is recommended that patients with one-time ACL injury should seek medical treatment in time and carry out scientific treatment and training under the guidance of professional doctors, so as not to miss the opportunity and cause serious adverse consequences.
