Anatomical PCL Reconstruction

A posterior cruciate ligament (PCL) injury is way less common than an ACL injury. It leads to a posterior knee joint instability (posterior drawer effect). The therapy must be immediate and requieres the physician to have a great deal of experience. It often is a combination of injuries with further ligament instabilities which must be co-treatended .F]

[F]Acute Injuries

If the PCL rupture is recongized in the first few days following the accident, non-surgical therapy due to a special splint, can lead to a stabil knee. In order to heal the PCL the splint must be worn consequently for approximatly 2-3 months during day and night.

Among active athletes simple arthroscopical surgeries can help to stabilise and recover the PCL (augmentation plastic). Therefore a fast rehabilitation and a fast return to sports is possible. Combined Injuries must be stabilized operational immediatly.

Chronic Injuries
In case of PCL injuries with low posterior instability ( < 1cm posterior drawer effect) surgicals are often not recommended. Most patients get along well with posterior instability. But in cases of pronounced instability and function limitations, a surgery indication exists. In these cases we suggest a PCL reconstruction with further ligament replacements.

Surgical Techniques

The operation is performed under general anaesthesia, so that the patient does not notices any of the operation. A torn PCL is mostly reconstructed with one of the hamstrings which makes the reconstruction similar to the ACL. As an alternative we can use a part of the quadriceps ligament. After the drill channels are made by arthroscopic techniques the graft is inserted and sufficiently anchored with bio bolts. In case of further ligament injuries we ensure that they will be provided properly. At the same time also cartilage and meniscus damages can be repaired.

Post-Op Treatment

The post-op treatment is time consuming and needs careful and prudent handling. Walking sticks and partial weight bearing (10 kg) are necessary for at least 6 weeks. The range of motion will be continuously expanded until you can reach the full range of movement within 2-3 months. We also prescribe a special knee splint which s supposed to be worn approximatly until 3 months post-op. Further we will disscuse the point of your work and sports return with you individually.
