Sports Medicine Knee Anatomy

Medial Collateral Ligament (MCL)

Found on the medial side of the knee, connects the femur to the tibia, stabilizes the medial aspect fo the knee

Quadriceps located

The anterior side of the thigh and extend the knee

Meniscus stabilizes

The knee joint, think on the outsides and thinner in the middle, forming a dish shaped hallow, the candles of the femur sits on the dish

Patella

A sesmoid or floating bone, that is embedded in the patellar tendon, nit glides up ad down not eh anterior side of the femur

IT band

Crosses the knee joint and provides stability

Epicondyles

End of the femur, medial and lateral

3 bones that make up the knee

Femer, tibia, patella

Lateral Collateral Ligament (LCL)

Found on the lateral side of the knee, connects the femur to the fibula, stabilizes the lateral aspect of the knee

Gracilis-medial

Groin muscle, that attaches to the pelvis, runs down the medial thigh and attaches to the medial surface of the tibia

Popliteus-posterior

Just behind the knee helps flex the knee

Condyles

Just below th epicondyles

Tensor Fascia Latae

Lateral found at the hip, turns into the iliotibial (IT) band

Sartorius

Longest muscles in the body, originates on the anterior pelvis,, runs down the length of the thigh and attaches on the medial surface of the tibia

Meniscus location

On both sides of the tibial plateau, forming the medial meniscus and the lateral meniscus

Tibial tuberosity

On the anterior aspect, just below the tibial plateau there is a small bump

Quadriceps attach

On the femur and pelvis and run towards the plateau, attach to the patella on the anterior aspect, after attaching to the patella the quadriceps turn into the patellar tendon, the patellar tendon attaches to the tibial tuberosity

Hamstrings help

Prevent forward movement of the tibia on the femur

Muscles of the knee

Provide stability and movement

Posterior Cruciate Ligament (PCL)

Runs from the anterior aspect of the Emirates to the posterior aspect of the tibial plateau, prevents posterior translation of the tibia on the femur, the ACL and PCL cross

Anterior Cruciate Ligament (ACL)

Runs from the posterior aspect of the femur to the anterior aspect of the tibial plateau, prevents anterior translation of the tibia on the femur

3 hamstring muscles

Semimembranosus, semitendinosus, biceps femoris

Meniscus

Sits on the tibial plateau, prevent the tibia and the femur from rubbing on each other, which would cause the bone to wear down quickly

Patellofemoral joint

The patella and femur form

Hamstring located

The posterior aspect of the thigh and flex the knee

Hamstrings attach

The posterior side of the pelvis and run down the back of the thigh, across the knee, and attach on the tibia

Primary muscles that move the knee

The quadriceps and hamstrings

Tibiofemoral joint

The tibia and femur are involved with the primary function of the knee

Tibialis plateau

Top of the tibia

4 quadriceps muscles

Vastus lateralis, vastus intermedius, vastus medalis,, rectus femoris
