Arthroscopic Anterior Cruciate Ligament Reconstruction.

What Is Anterior cruciate ligament reconstruction ?

Anterior cruciate ligament reconstruction (ACL reconstruction) is a surgical tissue graft replacement of the anterior cruciate ligament, located in the knee, to restore its function after an injury.The torn ligament is removed from the knee before the graft is inserted in an arthroscopic procedure.

How it happens?

The Anterior Cruciate Ligament is the ligament that keeps the knee stable.Anterior Cruciate Ligament damage is a very common injury, especially among athletes.ACL injury is 4-6 times higher in females than in males. An increased Q angle and hormonal differences are a few examples of the gender disparity in ACL tear rates.


ACL reconstruction now a days with the help of advanced science and technology done by key hole surgery that is arthroscopic surgery. Orthopaedic surgeon removes your torn ACL by arthroscopic technique, he puts a tendon or graft in its place. These graft are taken from hamstring, bone-patella tendon-bone graft, peroni or allograft.
Arthroscopic graft will placed at right spot, and he’ll drill two holes, called “tunnels.” He’ll drill one in the bone above your knee and another in the bone below it. Then, he’ll placeendo-button at upper bone tunnel of knee and screws in lower the tunnels and anchor the graft in place. It serves as a sort of bridge that a new ligament will grow on as you heal. It can take many months for a new ACL to grow in fully.


Initial physical therapy consists of range of motion (ROM) exercises, often with the guidance of a physical therapist. Range of motion exercises are used to regain the flexibility of the ligament prevent or break down scar tissue from forming and reduce loss of muscle tone.
Approximately six weeks is required for the bone to attach to the graft. However, the patient can typically walk on their own and perform simple physical tasks prior to this with caution, relying on the surgical fixation of the graft until true healing (graft attachment to bone) has taken place. At this stage, the first round of physical therapy can begin. This usually consists of careful exercises to regain flexibility and small amounts of strength. One of the more important benchmarks in recovery is the twelve weeks post-surgery period. After this, the patient can typically begin a more aggressive regimen of exercises involving stress on the knee, and increasing resistance. Jogging may be incorporated as well.
After four months, more intense activities such as running are possible without risk. After five months, light ball work may commence as the ligament is nearly regenerated. After six months, the reconstructed ACL is generally at full strength, and the patient may return to activities involving cutting and twisting if a brace is worn. Recovery varies highly from case to case, and sometimes resumption of stressful activities may take a year or longer.
