explain the Anterior cruciate ligament reconstruction with bone-patellar tendon-bone graft

Expert Solution

Ans :

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 can either be removed from the knee (most common), or preserved (where the graft is passed inside the preserved ruptured native ligament) before reconstruction an arthroscopic procedure. ACL repair is also a surgical option. This involves repairing the ACL by re-attaching it, instead of performing a reconstruction. Theoretical advantages of repair include faster recovery and a lack of donor site morbidity, but randomised controlled trials and long-term data regarding re-rupture rates using contemporary surgical techniques are lacking

Patellar tendon graft :

The patellar tendon connects the patella (kneecap) to the tibia (shin). The graft is normally taken from the injured knee, but in some circumstances, such as a second operation, the other knee may be used. The middle third of the tendon is used, with bone fragments removed on each end. The graft is then threaded through holes drilled in the tibia and femur, and screwed into place. It is slightly larger than a hamstring graft.

Disadvantages compared with a hamstring graft include:

Increased wound pain

Increased scar formation

Risk of fracturing the patella during harvesting of the graft

Increased risk of tendinitis.

Increased pain levels, even years after surgery, with activities that require kneeling.

Some or all of these disadvantages may be attributable to post-operative patellar tendon shortening.

Nakamura et al. studied subjects with medial collateral ligament (MCL) and anterior cruciate ligament (ACL) tears. Between February 1995 and December 1997, 17 consecutive patients with combined acute ACL and grade III MCL injuries were treated by the same physician at the research center. One of the variables of interest was the length of time in days between the occurrence of the injury and the first magnetic resonance imaging (MRI). We wish to know if we can conclude that the...

Clinical Application – exercise prescription rationale: Your patient has a complete Anterior Cruciate Ligament tear and is seeking information on rehabilitation. Define the primary role of the ACL in knee stability Which muscle(s) would be most important to assess during your examination and why? What technique would you use to most accurately evaluate the strength of this muscle (isometric vs dynamic contraction)? Provide one strengthening exercise with rationale that would support the rehabilitation of your patient with the ACL tear.

An 18-year old high school football player suffered a torn anterior cruciate ligament (ACL) in the state playoffs. After undergoing repair, he found it difficult to ambulate with the knee brace. Weighing close to 140 kg (approximately 300 pounds), the athlete found it difficult to stand and balance on one leg. His mother was unable to support him by herself. After one week, the young man began to have increased pain and swelling in the calf of his affected leg....
