Anatomy Lesson: Real Human Knee Dissection

Plyometrics, landing drills, balancing exercises, and well-rounded strength training programs are recommended to reduce the risk of ACL injuries.

It's fascinating to see the internal structure of a human knee and relate it to common knee pain issues like arthritis or ACL injuries.

A right knee is identified by the patella being anterior, the femur positioned upward, and the tibia on the medial side with the fibula on the lateral side of the lower leg.

The MCL (medial collateral ligament), LCL (lateral collateral ligament), ACL (anterior cruciate ligament), and PCL (posterior cruciate ligament).

Arthritis results in worn-out cartilage, leading to painful bone-on-bone interactions in the knee, often discussed in detail in videos on arthritis.

The ACL prevents anterior translation of the tibia, stopping it from sliding too far forward, and limits internal rotation and hyperextension of the knee.

It's a clinical test where a clinician pulls the tibia forward to check if the ACL stops its movement, indicating the ACL is intact or torn.

70% of ACL tears are non-contact injuries, often resulting from awkward landings or sudden twists.

Options include autografts using the patient’s own hamstring or patellar tendon, and allografts using donated tissue from cadavers.

An autograph is a graft taken from the patient's own body, commonly from the hamstring or patellar tendon, to reconstruct the ACL.

Pros include enhanced ACL strength; cons include initial decrease in hamstring strength and the graft lacking bone plugs, requiring proper fixation.

Using a patellar tendon graft can result in anterior knee pain, increased risk of fractures, and tendonitis.

An allograft is a donated tissue graft, often using the Achilles or patellar tendons, reducing donor site pain but increasing the risk of re-injury compared to autografts.

Incorporating neuromuscular training helps improve coordination and communication between nerves and muscles, reducing ACL tear risk by over 50% according to research.

It includes plyometrics, landing drills, balancing exercises, and strength training for muscle coordination and injury prevention.

Balancing strength between these muscle groups prevents anterior tibial translation, reducing the risk of ACL tears in individuals who may be quad dominant.

Plyometrics, landing drills, balancing exercises, and well-rounded strength training programs are recommended to reduce the risk of ACL injuries.
