Knee I

By Beverly Chen

1)Knee joint is the result of the fusion of

	Medial femorofibula
	Lateral femortibia
	infrapatella
	femoropatella

2)State which is true and false for the following statements

	The knee joint is formed by condules of femur,fibula , condyles of tibia
	The femoral attachment of the fibrous capsule , laterally it encloses the origin of the peroneus longus muscle
	Coronary ligament of the fibrous capsule is attached to the periphery of the menisci
	The cord-like thickening of the capsule deep to the fibula collateral ligament is known as the short lateral ligament

3)Which of the following is related to tibial collateral ligament ?

	It is the lateral ligament
	Superiorly , it is attached to the medial epicondyle of the femur
	The anterior part of the tibial collateral ligament covers the superior medial genicular vessel and nerves
	It  represents the degenerated tendon of adductor magnus morphologically .

4)True or false

	Ligamentum patellae is inserted to the tibial tuberosity
	The lateral ligament is superiorly attached to the lateral epicondyle of the femur just above the popliteal muscle
	Morphologically , the lateral ligament represents the femoral attachment of peroneus longus
	The middle genicular vessels and nerve pierces the oblique popliteal ligament

5)State which is true and false for the following statements

	Ligamentum patellae maintains the patella
	Only the tibial collateral ligament limit the extension of the knee joint
	Cruciate ligaments maintain the antero-superior stability of knee joint
	Posterior cruciate ligament is attached to the medial condyle of the intercondylar area of femur for the upper attachment
	Anterior cruciate ligaments limit the anterior displacement of femur
	Posterior cruciate ligaments limit the posterior displacement of tibia

6) Regarding the following statements of meniscus , which is true and false ?

	Meniscus helps to deepen the articular surface of femur
	Flexion of knee takes place in the lower compartment of the meniscus
	Outer border of the meniscus is thinner than the inner border
	Medial meniscus is comma-shaped
	Tendon of popliteus separate and the capsule separate the lateral meniscus from the tibial collateral ligament
	Medial meniscus is commonly injured

7)True or false

	The outer 1/3 of meniscus receives blood supply form the capsule
	Unhappy triad is due to the medial blow of the knee
	Menisci helps in lubricating the hip joint

8)True or False

	Synovial membrane of knee joint lines the whole capsule
	Infrapatella synovial fold is the lateral fold of the synovial membrane
	The bursae in the anterior part consist of subcutaneous infrapatellar bursa , suprapatella bursa , deep prepatellar bursa and subcutaneous prepatellar bursa
	Anserine bursa seperates the tendons of all the anterior muscles of the thigh
	Posterioirly , the relations of knee joint is related to the tendon of semimembranosus
	Knee joint is supplied by the descending genicular branch of femoral artery , 2 recurrent branches of the anterior tibial artery , 5 genicular branches of popliteal artery , descending genicular branch of lateral circumflex femoral artery
	The nerve supply related to the knee joints are femoral nerve common peroneal nerve , and obturator nerve

9)True or False

	Medial rotation of femur on tibia , during the last 30 degree of flexion
	For the locking action of the knee joint , involves only the vastus medialis muscle
	The muscles involved for the external rotation with the flexed knee is biceps femoris
	During the locking of the knee joint , the anteroposterior diameter of the lateral femoral condyle is less than the medial condyle
	Unlocking mechamism of the hip joint is helped by the action of the popliteus muscle
	Infrapatellar synovial fold indicates the lower limb of femoropatellar joint

10) True or Flase

	If the meniscus is destroy , it will lead to an increase in osteoarthritis
	Tibial condyles are big
	Collateral ligaments help in the maintenance of the side to side stability
	Iliotibial tract helps in the stability of the knee joint
	The abnormal of the abductor of leg is known as knock knee
	Injuies to the collateral ligament is more common than the injury to the cruciate ligament
	Patella-femoral joint is due to the mal-alignment of patella
	Baker’s cyst is a central swelling of knee
	Knee joint disease vastus medialis is first to atrophy and last to recover
