If the leg is not straight after a fall and the injury is only to soft tissue or ligaments, it is usually possible to recover in about four weeks after targeted treatment. If the leg is not straight due to serious knee injuries, such as patella fracture, meniscus tear, etc., you need to undergo surgical treatment to recover.
1. Mild knee injury: soft tissue swelling affects leg straightening, after local braking and rest, the swelling can be eliminated gradually. During this period, you can strengthen the knee extension exercise, you can do more leg press activities, pull the adhesion and contracture of the joint capsule, in order to promote the recovery of knee flexion and extension function.
In the process of functional exercise, hot compresses and physiotherapy can be used to soften the adhesion and stiffness of the joint capsule, so as to promote the restoration of the straightening function of the leg. Usually it takes about four weeks to recover completely.
2. Severe knee injuries: such as patella fracture and dislocation, meniscus tear, etc., resulting in the inability to straighten the knee. Surgical incision and internal fixation or arthroscopic minimally invasive surgery is needed to close the meniscus, restore the flatness of the meniscus and the alignment and alignment of the fracture, and help the patient return to normal function.
If the leg cannot be straightened after a fall, it is recommended that the patient should seek medical treatment in time and under the guidance of the doctor to avoid the adverse consequences.
