Cruciate ligament surgery: Kreuzbandriss and cruciate ligament replacement

Agility and grip of the legs depend crucially on a stable knee joint from. Ensure ligaments and muscle tendons. In addition to two side bands, the cross of two knee ligaments kept the rear and front.

The knee

The knee is the largest joint in the human body. It combines the two main bones: the femur and the tibia. In addition, it is the bony kneecap (patella). A joint capsule seals the knee joint from the outside. Between the two ends of bones and cartilage coating is the joint space with joint fluid and the two crescent menisci. They consist of fibrous cartilage and have the function of a "shock" in the joint.

Typical knee injury: The front Kreuzbandriss

The complex structured knee is very vulnerable. Often there is damage to the anterior cruciate ligament as a result of sports injuries, especially by the growing popularity of leisure with ever more extreme sports. But even more stringent requirements in competitive and novel materials for the equipment in the incumbent sports (for example, carving skis) lead to a higher risk of injury. If the knee joint, for example, overstretched or twisted at a fixed lower, the anterior cruciate ligament tearing - often associated with concomitant meniscus and cartilage damage. As a result of the cruciate ligament rupture, the knee is no longer sufficiently stable, the movements are limited, walking is unsafe and it comes to the uncontrolled "Wegknicken". This allows more meniscus and cartilage damage. Signs of a thick Kreuzbandriss are bruises in the knee joint and severe pain.

Treatments at a Kreuzbandriss

Cruciate ligament injuries


are both non-operatively and treated surgically, depending on the individual. Missing the anterior cruciate ligament, an osteoarthritis (cartilage wear) inevitable - just like the next accident, which by then will destroy healthy meniscus. It is clearly recommended that the cruciate ligament by an operation to replace. Exception is elderly patients who do not exercise or have significant cartilage damage. Suffice usually Auftrainieren and strengths of the thigh muscles to stabilize the knee joint (zofran, zofran odt, zofran dosage, generic zofran). For younger, active people sports is an operation in any case advisable, as well as physically strenuous occupations or if a Kreuzbandriss with other knee injuries combined. The most commonly performed surgical method with a torn anterior cruciate ligament is its replacement by a body's tendon (Kreuzband plastic).

Operating cruciate ligament replacement


In a gentle "minimally invasive" surgery, the doctor of a tiny incision a probe with a mini-camera into the knee joint, and examined the defect (arthroscopy). About a second incision, he removed with fine instruments, the remains of the torn cruciate ligament. At the same time, he can determine exactly where the tear tape with the femur and the tibia was connected. This is important for the subsequent attachment of the new cruciate ligament replacement. Then, from the patella tendon (Patellaband) or a tendon from the inside of the knee Beugeseite (often Semitendinosus) a piece of tendon taken and at the site of the old cruciate ligament used. The transplanted tendon pieces verwächst within six weeks with the bones, stabilizes the knee again and takes over all functions of the cruciate ligament. In the first ten months after the surgery, the transplant, however, vulnerable to a re-injury. Just as important as the surgery itself is the post-treatment. Without an adequate rehabilitation complaints are very likely.
