Acl (Anterior Cruciate Ligament) Injury
Knee hyperextension: The ACL may tear when certain movements of the knee place a great strain on the acl. Hyperextension of the knee, that is, if the knee is straightened more than 10 degrees beyond its normal fully straightened position, is a very common cause of an torn acl. This position of the knee forces the lower leg excessively forward in relation to the upper leg. Pivoting injuries of the knee with exc. ...Read moreSee 2 more doctor answers
Ligament injuries run the full spectrum from being sprained to being completely torn. Sprains are routinely graded as 1, 2 or 3. Grade 1 & 2 sprains represent ligaments that are intact, but not functioning normally either by causing pain with use (grade 1), or pain and mild looseness or laxity (grade 2). Grade 3 sprains are complete ...Read more
Giving way: Classically people describe a buckling, twisting, or giving way episode in the knee, with a popping feeling. Sometimes the pop is audible. Commonly there is swelling, limited ability to walk, and then associated stiffness+pain; as swelling goes down, pain will go away, but instability (wobbly/buckling) feeling with quick changes of direction persists; some people have minimal pain/swelling. ...Read more
Significant: Acl tear is a significant injury to the knee. It can significantly affect the function of the knee. Especially pivoting activities. Acl injury can occur in motor vehicle accidents, falls, and most commonly in sports. The acl can tear in an injury involving knee contact with someone or something or without any knee contact. Acl is generally fixed to restore the best possible function to your knee. ...Read moreSee 1 more doctor answer
Swelling/bone bruise: Initial pain after tearing your acl is due to 3 main reasons. 1) bleeding from the tear fills the knee exerting pressure on the capsule which is very sensitive to pressure. 2) the forces that cause the tear cause the femur and tibia to smack together leaving characteristic bone bruises in the femur and tibia. 3) additional injuries, most commonly meniscus tears can add to the pain of acl injury. ...Read moreSee 1 more doctor answer
Train neuromuscular: There is evidence to show that neuromuscular training including plyometrics, balance, and technique training, as well as heightened awareness of injury biomechanics, reduce the risk of serious injury in female athletes. What specific exericises, sequence, intensity and duration remains unknown. ...Read moreSee 1 more doctor answer
Most choose surgery: Sugical reconstruction is the most common treatment, although some will elect to only treat with physical thearpy. When pursuing surgery there are many graft options, but despite which one the surgeon may use the procedure includes putting tunnels in the bones of the knee and threading the graft through to replace the original ligament. Trying to reconnect the ends of the original lig doesn't work. ...Read moreSee 3 more doctor answers
How long does it take to recover from a anterior cruciate ligament (acl) injury and to be able to play sports?
Depends: There are many variables that will effect the time necessary to recover enough to return to sports including the graft used, fixation techniques and the biases of the surgeon. Because some studies suggest return to sports prior to 9 months post surgery may increase the risk of reinjury, i prefer to have my patients wait 9 months. That is not to say some athletes have been able to return quicker. ...Read moreSee 2 more doctor answers
PE and MRI: The first step is checking for an acl injury is talking to the patient about their injury and doing a good physical exam of the knee (pe). At this point, most skilled doctors will have a strong suspicion that the acl is torn. X-rays are usually done to make sure there isn't a bad bone injury. Often a MRI is obtained to confirm the diagnosis and look for other, associated injuries. ...Read more
Instability: The hallmark of an acl deficient knee is instability or giving way of the knee with higher level activities involving cutting, jumping, pivoting, etc. Some individuals may experience this with routine day to day activities. The initial injury is often described as feeling a "pop" in the knee and followed by development of considerable swelling and variable pain. ...Read moreSee 2 more doctor answers

Depends: In general it leads to instability of the knee when completely torn and should be repaired or braced to avoid furthervinjury to other structures in her knee. If only the posterior bundle is injured, however, the knee remains stable. The most important factor is her age. If she is past maturity above applies, otherwise she may respond to primary repair. ...Read moreSee 1 more doctor answer
Pain, swelling: The majority of ACL tears are noncontact injuries. The classic history is when a person plants and twists a leg, or rapidly changes directions and then hears or feels a pop in the knee. Initial pain tends to be severe, but in some, only lasts a few minutes. Swelling tends to occur within the first hour and most limp for days to weeks. The knee then often gives out or buckles, signs of instability. ...Read moreSee 1 more doctor answer
ACL Reconstruction: Yes, you can still have an acl reconstruction. Acl tears do not heal on their own & having it replaced can help you maintain a healthy/ active lifestyle in the years to come. The acl is a major knee stabalizer, and can provide security to your knee that may prevent further damage to nearby tendons, ligaments, muscles, articular cartilage, meniscus, & bones when compared to a "loose knee" ...Read more
