can the acl slip out of place?

Question

Does having a ACL problem cause you to have slipping in the knee and instability?

Answer 1

No: The acl cannot "dislocated" per se and still be intact. If this occurs you would have an acl tear.

Answer 2

Controversial: This type of procedure is advocated by some surgeons in an effort to avoid revision ACL reconstruction surgery. I do not advocate it as the thermal activity can damage the ACL graft tissue and will not (and has not been supported in the literature) have any long term effect on the loose graft. If the knee/graft is loose/unstable, the surgery needs to be fully revised in my opinion.

Answer 3

Heat shrinks lax ACL: Thermal shrinkage for ACL stretch or partial injuries can provide short term benefit for ACL laxity, but leads to catastrophic failure with longer term follow-up. Thermal shrinkage can no longer be recommended for the treatment of ACL laxity.

Answer 4

Cutting Sports: Sudden changes in direction or rotational movements are common mechanisms of the "non-contact" ACL injury. Hyper-extension or hyper-flexion can also damage the acl. Contact injuries, such as a blow to the side of the knee, can also often result in an ACL injury.

Answer 5

Pivoting and cutting: Acl injury commonly occurs with pivoting and cutting activities. Patients often recollect a definitive pop and near immediate swelling at the time of injury. Subsequent complaints of buckling and giving away are also common.

Answer 6

Let me show you: http://en.wikipedia.org/wiki/anterior_cruciate_ligament.

Answer 7

ACL location: Acl runs inside your knee from the posterolateral distal femur to the anteromedial aspect of the tibia, in the knee joint. I tell patients it roughly runs in the same direction as putting your hands in your pocket.

Answer 8

ACL: An anterior cruciate ligament, or ACL, injury is a a knee ligament that joins the upper leg bone with the lower leg bone . The ACL keeps the knee stable. Injuries range from mild, such as a small tear, to severe, such as when the ligament tears completely or when the ligament and part of the bone separate from the rest of the bone. http://www.miamisportsmedicine.com/ACLTears.html

Answer 9

No: The ACL torn is from an injury not overuse. Injuries occur with falls and you are more likley to fall when tired or distracted, when using a new board, going out in rough. If you are surfing or participating in any sporting endeavor, there is always the risk of knee injury and that includes ACL tear, but you can minimize the risks by being alert, careful, and staying healthy.

Answer 10

No: While anatomic factors may play a role in increasing your risk of acl injury, it usually requires twisting forces higher than what you would experience on a long board. More likely with a short board.

Answer 11

No: Acl injuries among surfers is not that common because the knee can rotate and pivot along with the surfboard rather than be fixed on a planted surface. In surfing the knee is probably most at risk when spin and land impacting the wave. However it is rare.

Answer 12

Yes: Agenesis or congenital absence of the ACL has been described in patients who are born without an acl. It is rare and may be associated with absence of a meniscus, limb length discrepancy. Typically the patients have symptomatic instability causing them to seek care, which usually requires surgical ACL reconstruction.

Answer 13

Rare: It is possible but this would be a congenital abnormality and very rare.

Answer 14

Extremely rare: Very few cases have ever been identified of patients born without an ACL. It is more common to have an ACL removed after a traumatic incident - some of these patients have continued playing competitive sports with ACL focusing on strengthening the other supporting muscles and ligaments instead to stabilise the knee
