As knee surgery specialists in Freiburg we use the semitendinosus tendon for a torn cruciate ligament, and alternatively the patellar tendon or the quadriceps tendon. These replacement tendons have proved their worth in cruciate ligament surgery over many years. Once in place, they have a tensile strength and elasticity similar to that of the natural cruciate ligament. Numerous studies confirm the excellent results. The semitendinosus tendon is one of several flexor tendons at the knee. Its removal is tolerated without any loss of strength or movement. Taking the tendon through a small incision on the inner side of the knee leaves a scar that is barely visible.
How does cruciate ligament surgery work?
Replacing the anterior cruciate ligament entirely by arthroscopy puts far less strain on the knee joint than an open procedure. There is considerably less knee pain after cruciate ligament surgery and rehabilitation can begin very early. What decides the success of the operation is placing the bone tunnels precisely at the attachment points of the original cruciate ligament. Using accurate guides, these tunnels can be drilled exactly, under arthroscopic control. To give it sufficient tensile strength, the tendon is folded three or four times.
The replacement tendon is first drawn into the knee joint through the tunnel in the upper tibia and then fixed in the tunnel in the thigh bone with two absorbable pins (cross-pin fixation). The alternative fixation with a small titanium plate on the toggle-anchor principle has likewise proved reliable.
To fix the tendon at the upper tibia we use a small titanium button. This new method of fixation allows very stable anchorage and ensures that the tendon heals in without difficulty. Later removal of the metal is usually unnecessary. Accompanying damage to the meniscus or the cartilage can be treated at the same time.

Rehabilitation
Rehabilitation after cruciate ligament surgery runs in several phases and is decisive for the success of the operation. Our experienced physiotherapists accompany you through the whole healing process.
Phase I (weeks 1 to 6)
The first phase of rehabilitation concentrates on restoring movement and reducing pain. Careful mobilisation exercises and lymphatic drainage encourage healing.
Phase II (weeks 6 to 12)
The second phase comprises exercises to stabilise and strengthen the knee joint and a step-by-step return to everyday activities. The load is increased continuously.
Phase III (months 4 to 6)
Phase III focuses on taking up lighter sporting activity again and on building up the muscles. Running exercises and sport-specific training are introduced.
Phase IV (months 7 to 9)
The final phase aims to restore full load-bearing capacity and to integrate sporting activity completely. Regular check-ups ensure that healing takes its best course.
