Q

patellar tendon

A
  • Inserts on tibial tuberosity
  • Patellar tendon tenderness or inability to extend knee may suggest complete or partial tear of patellar tendon
  • -High riding patella
  • Patellar tendon tear most often associated with running and jumping activities and higher risk if a person has pre-existing tendonitis (if you are told you have patellar tendonitis– rest, don’t run or jump!)

Q

effusions

A
  • Joint Effusion: fluid in synovial joint cavity
  • Assess for Balloon, Ballottement, and Bulge signs
  • Differentiate from Pre-patellar bursitis: fluid in patellofemoral compartment (not an effusion) or swelling associated with osteoarthritis
19
Q

bulge sign

A

milk effusion inferiorly and laterally then tap on the lateral margin to assess for fluid bulge toward the medial margin

20
Q

balloon sign

A

compress suprapatellar pouch downward and feel for fluid wave around the patella (medially and laterally)

21
Q

ballottement sign

A

compress suprapatellar pouch then push “ballot” patella and watch for return of fluid to the pouch

22
Q

special test for the knee

A
  • Test for patellofemoral syndrome:
  • -Patellofemoral grind test
  • Tests for effusion:
  • -Bulge Sign
  • -Balloon Sign
  • -Balloting the patella
  • Tests for ligament stability:
  • -Varus and Valgus stress tests: LCL, MCL
  • -Lachman’s: ACL
  • -Anterior drawer: ACL
  • -Posterior drawer: PCL
  • -McMurray’s: meniscus
23
Q

patellofemoral syndrom

A

nonspecific term for pain in front/center of knee, can be from chondromalacia patella, patellar tendonitis; to perform grind test, have patient extend leg fully, put pressure on the knee and have the patient flex the quadriceps; a positive test will cause grinding and pain under the patella.

24
Q

ACL tear

A

common in sports injuries, usually associated with effusions immediately following the injury
For the anterior drawer test, the patient assumes a supine position with the injured knee flexed to 90 degrees. The physician fixes the patient’s foot in slight external rotation (by sitting on the foot) and then places thumbs at the tibial tubercle and fingers at the posterior calf. With the patient’s hamstring muscles relaxed, the physician pulls anteriorly and assesses anterior displacement of the tibia (anterior drawer sign).

25
Q

lachman test

A

assessing the integrity of the anterior cruciate ligament. The test is performed with the patient in a supine position and the injured knee flexed to 30 degrees. The physician stabilizes the distal femur with one hand, grasps the proximal tibia in the other hand, and then attempts to sublux the tibia anteriorly. Lack of a clear end point indicates a positive Lachman test.

26
Q

posterior drawer test

A

patient assumes a supine position with knees flexed to 90 degrees. While standing at the side of the examination table, the physician looks for posterior displacement of the tibia (posterior sag sign). Next, the physician fixes the patient’s foot in neutral rotation (by sitting on the foot), positions thumbs at the tibial tubercle, and places fingers at the posterior calf. The physician then pushes posteriorly and assesses for posterior displacement of the tibia

27
Q

valgus stress test

A

performed with the patient’s leg slightly abducted. The physician places one hand at the lateral aspect of the knee joint and the other hand at the medial aspect of the distal tibia. Next, valgus stress is applied to the knee at both zero degrees (full extension) and 30 degrees of flexion. With the knee at zero degrees (i.e., in full extension), the posterior cruciate ligament and the articulation of the femoral condyles with the tibial plateau should stabilize the knee; with the knee at 30 degrees of flexion, application of valgus stress assesses the laxity or integrity of the medial collateral ligament.

28
Q

varus stress test

A

physician places one hand at the medial aspect of the patient’s knee and the other hand at the lateral aspect of the distal fibula. Next, varus stress is applied to the knee, first at full extension (i.e., zero degrees), then with the knee flexed to 30 degrees. A firm end point indicates that the collateral ligament is intact, whereas a soft or absent end point indicates complete rupture (third-degree tear) of the ligament.

29
Q

McMurray test

A

physician grasps the patient’s heel with one hand and the knee with the other hand. The physician’s thumb is at the lateral joint line, and fingers are at the medial joint line. The physician then flexes the patient’s knee maximally. To test the lateral meniscus, the tibia is rotated internally, and the knee is extended from maximal flexion to about 90 degrees; added compression to the lateral meniscus can be produced by applying valgus stress across the knee joint while the knee is being extended. To test the medial meniscus, the tibia is rotated externally, and the knee is extended from maximal flexion to about 90 degrees; added compression to the medial meniscus can be produced by placing varus stress across the knee joint while the knee is being extended. A positive test produces a thud or a click, or causes pain in a reproducible portion of the range of motion.
