~Anterior Cruciate Ligament Injury Symptoms, Testing, and Treatment
"I twisted my knee landing on a jump," he said, "and my knee hurt like hell when I changed direction."
If you are then unable to walk due to swelling, it isAnterior cruciate ligament (ACL) injuryIt may be.
Anterior cruciate ligament injuries are,Serious knee injuries common in young adults and sports enthusiastsIt is. Early and accurate diagnosis and treatment is very important because, if left untreated, it can lead to future joint deformities.
In this issue, we will discuss the causes, symptoms, testing, and treatment of ACL injuries, as well as the latest topic, the ALL (anterior lateral ligament).
What is an anterior cruciate ligament (ACL) injury?
The anterior cruciate ligament is,Located in the middle of the knee joint, an important ligament that connects the femur to the tibiaAnd, mainly inRole in preventing the tibia from sliding forward.The company is responsible for
ACL injuries often occur in the following situations
- Landing after a jump (basketball, volleyball)
- Sudden change of direction (soccer and rugby)
- Sudden stopping action or contact play
- Strong knee contusion from car accident
It accounts for about 45% of all knee ligament injuries,Complications such as meniscus and medial collateral ligament (MCL) injuries are also common.
[Main symptoms
- Severe pain and swelling of the knee (especially immediately after the injury)
- Due to intra-articular hemorrhage,Within a few hours, the knee swells into a bunion.
- You may also feel a "buzzing" sound of rupture.
- Pain improves over time, but instability (knee collapse) remains
This "knee collapse" is a major barrier for those seeking to return to sports.
[Inspection
Clerical examination
The ACL isLigament that controls the forward movement of the tibiaand the following tests confirm instability:
- Forward pull-out test
- Lachman TestPositive with findings such as: pulling the tibia forward with the knee lightly bent, "pulled out", "no stop", etc.
- Jerk test:The test is used to evaluate ACL injury and damage to the anterolateral structures, and is considered positive when the tibia is momentarily displaced by applying internal rotation while extending the knee, known as a “jerking phenomenon.
Image Inspection
- X-rays and echoes: exclusion of fractures and other diseases (e.g., plateau fractures, splintered bone fragments, etc.)
- MRI scan(Referral to affiliated medical facility if necessary): Confirm ACL injury/tear,Evaluation of meniscus and other ligamentous injuriesuseful for
[Latest Topic: What is ALL (anterolateral ligament)?
In recent years, the anterolateral ligament (ALL) has been the focus of much attention.
The ALL is considered a ligament that stabilizes the rotation of the knee joint in conjunction with the ACL,If the ALL is also damaged along with the ACL injury, instability against knee torsion (rotation) remains strongWe have come to understand that
Currently,Simultaneous reinforcement and reconstruction of the ALL during ACL reconstruction reduces the risk of re-tear and knee instabilityIncreasingly, there are reports that it is possible toALL reconstruction is also increasingly being considered for athletes at higher levels of competition.
Treatment
Conservative therapy (non-surgical)
- For those who do not wish to return to sports or for the elderly
- Strengthen quadriceps and hamstrings in rehabilitation
- Limit to mild exercise such as jogging
- However,Progressive meniscus damage and articular cartilage damage due to recurrent knee collapsesThere is a risk of
Surgical treatment (ACL reconstruction)
- Recommended for young adults, athletes, and those with high activity levels
- Artificial reconstruction of ligaments (using patellar tendon, semitendinosus tendon, etc.)
- Including rehabilitationIt takes about 6-12 months to return to sports.
- The re-tear rate is estimated to be about 3-101 TP3T,Continued postoperative training is important.
If left unattended,5-10 years after injury, 40-601 TP3T progress to osteoarthritis of the kneeThe company is considered to be a "global company",Treatment selection from a long-term perspective is important.It is.
Examinations and treatments available at Ikejiri-Ohashi Sera Clinic
The clinic offers the following responses to knee trauma, including ACL injuries
Inspection
- Manual examination (Lachman, anterior drawer, etc.)
- Echo and X-ray examinationExclusion of other diseases by
- If MRI is needed, prompt referral to an affiliate
Treatment
- Exercise guidance for those on conservative therapy, focusing on strength training
- If surgery is required, referral to a specialist at the appropriate time
- Continued rehabilitation support for return to sports is also available.
Summary
Anterior cruciate ligament injuries are a common problem for young people and those who enjoy sports.Injuries that significantly affect daily life and future joint functionIt is.
RecentlyThe presence of ALL (anterior lateral ligament) and reconstruction methods have also attracted attentionReconstructive surgery is evolving to be safer and more effective than ever before.
If you have discomfort or instability in your knee,We recommend that you have a professional evaluation as soon as possible.
