How long it takes to bend a fractured patella varies depending on the type of treatment taken. Generally plaster immobilization takes 4 to 6 weeks and surgical treatment in 1 to 2 days.
Plaster immobilization:If the treatment method of plaster immobilization is adopted, usually there is no obvious displacement of the fracture site.
At the beginning, the joint is in a kind of stiff state, and the restoration of joint function requires gradual activities, because after 4~6 weeks, the stability of the fracture end has formed a certain connection, so you can do some moderate bending, and if you need to bend in the early stage, it is recommended that you should be guided by the doctor.
2. Surgical treatment: If the patella fracture is treated surgically, then the leg bending exercise can be carried out 1~2 days after the operation. Because the stability of the fracture end under the internal fixation of the surgery can fully meet the requirements of activities, usually in this case, it is recommended to carry out the bending exercise of the knee as soon as possible to avoid the sequelae that may be left after the fracture.
Depending on the individual’s condition, the treatment plan will be different, so you need to standardize the treatment and carry out leg bending exercises under the doctor’s guidance to achieve the best therapeutic effect.
