Flashcards
Anterior Cruciate Ligament (ACL)
Anterior Cruciate Ligament (ACL)
One of the four main ligaments that help stabilize the knee joint. It connects the femur (thigh bone) to the tibia (shin bone).
ACL Function
ACL Function
The ACL helps prevent the tibia (shin bone) from rotating during exercise, keeping the knee joint stable.
ACL Injuries more common in females
ACL Injuries more common in females
ACL injuries are more common in women due to factors like anatomy and muscle strength differences.

Study Notes
Viva Voce Stations
- Four stations are available
- A coin toss determines the station, potentially leading to eight injuries.
- Two stations are for acute injuries.
- Two stations are for chronic injuries.
Viva Topics
- Anterior Cruciate Knee ligament injury
- Elbow joint dislocation
- Hamstring strain
- Ankle sprain
- Patella tendonitis
- Osgood-Schlatters syndrome
- Plantar fasciitis
- Chondromalacia patellae
Anterior Cruciate Ligament (ACL)
- Anatomy: One of four main knee ligaments that stabilizes the joint.
- Location: Inserts onto the femoral condyle and tibial plateau (top of shin bone).
- Function: Stabilizes the femur on the tibia, preventing tibial rotation during exercise.
ACL Predisposing Factors
- Fatigue: Lack of concentration
- Gender: Females more susceptible
- Age: Commonly amongst 15-25 year olds
- Sports: Football (soccer)
- Surfaces: Wet or artificial turf potentially increase risk
ACL Mechanism of Injury
- Cutting Manoeuvres: Occurring during 10-30 degrees of knee flexion, with a valgus position and upper body rotation for cutting.
- Single Leg Landing: Changing direction rapidly increases the risk of varus-valgus stress and internal rotation.
- Deacceleration: Rapid changes in direction, increasing varus-valgus and internal rotation.
Treatment of ACL Injury
- Surgery: Reattaching ligaments to tibia or femur or using synthetic materials to replace the entire ligament.
- Brace: Supportive knee brace to improve knee joint stability.
- Rehabilitation (Rehab):
- 6-12 months duration
- Initial focus on strengthening hamstrings for 4-6 weeks to control knee movement
- Gradual strengthening of quadriceps for knee extension
- Increase exercise intensity as recovery progresses.
