Introduction
A torn inner ligament in the knee joint usually requires splinting of this joint to stabilize it. This type of injury usually occurs during sports activities in combination with excessive movement of the knee joint.
Splint as therapy concept for torn inner ligament of the knee
If no other structures in the knee are injured and the knee joint is stable, a conservative therapy with immobilization and splinting is usually completely sufficient. This initially restricts the mobility of the knee joint and thus prevents overloading or incorrect loading due to the lack of stabilization caused by the injured inner ligament. The radius of movement can then be adjusted to the current degree of healing of the knee joint.
The main aim is to prevent excessive flexion of the knee joint at the beginning. In the further course of therapy and in conjunction with physiotherapeutic measures, the maximum degree of flexion permitted by the splint can then be increased. There are various therapy concepts for this purpose, but as a guideline a maximum of 60 degrees of flexion can be assumed at the beginning and after a few weeks a maximum of 90 degrees.
After about six weeks and in consultation with the treating physician, the splint can usually be removed. But even after the splint treatment, special muscle building exercises should be performed to ensure permanent knee stability. Only if there are accompanying injuries or if there is instability in the knee joint should surgery be performed.
Wear splint at night
If a splint has been prescribed by a doctor in the context of an inner ligament rupture, it should also be worn at night. Especially at night, many uncontrolled movements take place during which the knee can be moved very unfavorably. The splint is designed to limit the range of motion of the knee joint flexion.
However, this is often taken by itself during sleep and can then have a negative effect on the healing process. If the splint is felt to be a nuisance at night, additional padding with absorbent cotton or soft clothing under the splint may be able to provide some relief. The healing time will be shortened if the therapeutic measures are followed consistently.
