Knee
Cruciate Ligament Injuries
Collateral Ligament Injuries
The anterior and posterior cruciate ligaments are the central stabilisers of the knee joint. The joint also features medial and lateral collateral ligaments. Ligament injuries often result from indirect force with twisting of the joint, frequently during sports.
When is surgery needed?
Some ligament injuries can be treated conservatively by temporary immobilisation in a brace. Extensive rupture of multiple ligaments rarely necessitates immediate surgical repair. In the event of an injury to the anterior or posterior cruciate ligament, surgery becomes necessary due to a subjective feeling of joint instability, in young individuals, during sporting activities, and in the presence of concomitant injuries.
What happens during surgery?
Cruciate ligament surgery is performed using an arthroscopic technique. A hamstring tendon is harvested through a small incision. This is then inserted into the joint via corresponding drill channels in place of the cruciate ligament and secured with metal plates and, if necessary, screws.
Aftercare
Following cruciate ligament surgery, partial weight-bearing on crutches and medicinal thrombosis prophylaxis are required. Knee function is subsequently restored through physiotherapy and an individual rehabilitation programme. The joint is stabilised by a special brace for 6 weeks. The period of incapacity for work after such a procedure is 14 to 21 days for desk-based activities and 10 to 12 weeks for physical labour. Sporting activities can be resumed after 6-12 months.
