Questions Knee Joint

Concerning the knee joint

1 the tendon of popliteus is intracapsular

2 the medial collateral ligament is attached to the medial meniscus

3 the lateral collateral ligament is attached to the lateral meniscus

4 it usually communicates with the synovial cavity of the superior tibio-fibular joint

5 the anterior cruciate ligament is attached to the medial femoral condyle

5 the anterior cruciate ligament is attached to the medial femoral condyle

F

The medial collateral ligament blends with the medial aspect of the capsule of the knee joint, and through the capsule, with the medial edge of the medial meniscus.Unlike the medial collateral ligament, the lateral collateral ligament does not blend with capsule of the knee joint.It is exceptional for the superior tibiofibular joint to communicate with the knee joint cavity.The anterior cruciate ligament runs upwards, laterally and backwards from the tibial plateau to the medial surface of the lateral femoral condyle.

Question 1 – knee joint

The anterior cruciate ligament

1 is attached to the lateral condyle of the femur

2 is intracapsular and intrasynovial

3 is lax when the knee is extended

4 functions to resist backward displacement of the femur on the tibia

5 is attached on the tibial plateau posterior to the attachment of the anterior horn of the medial meniscus

Question 2 - knee joint

The anterior cruciate ligament

1 is attached to the lateral condyle of the femur T

2 is intracapsular and intrasynovial F

3 is lax when the knee is extended F

4 functions to resist backward displacement of the femur on the tibia

T

5 is attached on the tibial plateau posterior to the attachment of the anterior horn of the medial meniscus

T

The cruciate ligaments are intracapsular but extrasynovial!


Concerning the knee joint:

1 its synovial cavity always communicates with the suprapatellar bursa

2 the menisci are intracapsular

3 the cruciate ligaments are avascular

4 the posterior cruciate ligament prevents backward displacement of tibia relative to the femoral condyles

5 the menisci are made of hyaline cartilage

T

5 the menisci are made of hyaline cartilage F

The menisci are made of fibrocartilage, not hyaline cartilage.


The medial meniscus of the knee joint:

1 has a greater antero-posterior dimension than the lateral meniscus

2 is less commonly injured than the lateral meniscus

3 has a better blood supply to its inner part than to its periphery

4 is attached to the medial collateral ligament

5 is flatter on its tibial aspect than on its femoral (upper) surface

With regard to the lateral meniscus of the knee joint

1 it is wider than the medial meniscus

2 it is attached to the lateral collateral ligament of the knee joint

3 the meniscofemoral ligaments are attached to its posterior aspect

4 the tendon of popliteus is attached to it

5 its anterior horn is attached in front of the attachment of the anterior cruciate ligament on the tibial plateau

Concerning the medial aspect of the knee region:

1 skin over the medial aspect of the knee is supplied by a branch of the saphenous nerve

2 the long saphenous vein, in an adult, is 2 cm behind the medial border of the patella

3 the medial collateral ligament is attached to the medial surface of the tibial shaft

4 the medial aspect of the capsule of the knee joint receives an extension from the semimembranosus tendon

5 fibres of the vastus medialis muscle attach directly to the medial border of the patella

T

The nerve that supplies the skin over the medial aspect of the knee is known as the infrapatellar branch of the saphenous nerve.The long saphenous vein is a hand’s breadth behind the medial border of the patella.


The following ligaments help to stabilise the knee joint

1 Anterior cruciate ligament

2 Long plantar ligament

3 Oblique popliteal ligament

4 Ligamentum teres

5 Pectineal ligament

3 Oblique popliteal ligament T

4 Ligamentum teres F

5 Pectineal ligament F

The long plantar ligament is found in the foot.The ligamentum teres in found in the hip joint.The pectineal ligament is an extension of the pectineal part of the inguinal ligament.


The medial collateral ligament of the knee is

1 A cord-like structure

2 Attached to the tibia

3 Attached to the medial meniscus

4 Pierced by the tendon of popliteus

5 Closely related to the common peroneal nerve

The medial collateral ligament of the knee is also known as the tibial collateral ligament and is a broad flat band attached to the medial femoral condyle and shaft of the tibia.Some of its deepest fibres attach to the medial meniscus.The popliteal tendon pierces the capsule of the knee joint, not the medial collateral ligament.

The anterior cruciate ligament of the knee

1 Is completely surrounded by synovial membrane

2 Is associated with the meniscofemoral ligaments of Wrisberg and Humphry

3 Is stronger and has a greater width than the posterior cruciate ligament

4 Limits rotation in the knee

5 Attaches to the anterior part of the intercondylar fossa of the femur

T

The synovial membrane covers the sides and front of the cruciate ligaments.The meniscofemoral ligaments are associated with the posterior cruciate ligament.Both cruciates limit medial rotation of the tibia or lateral rotation of the femur.The ACL attaches to the medial surface of the lateral condyle of the femur.

Bursae in and around the knee are located as follows:

1 Deep to the quadriceps

2 Between the cruciate ligaments

3 Between the ligamentum patellae and tibia

4 Deep to semimembranosus

5 In the subcutaneous tissue in front of the patella

The suprapatellar bursa is found deep to the quadriceps and is continuous with the synovium of the knee joint. It extends for 8-10cm above the superior border of the patella.
