Common Knee Pathologies Chapter 19

Front 1

Genu Valgum

Back 1

Knock knees, is an alignment of the lower extremity in which the distal segments (ankle) are positioned more laterally than normal. The knees tend to touch while the ankles are apart.

Front 2

Genu Varum

Back 2

Bowlegs. Is the opposite alignment problem in which the distal segments are positioned more medially than normal. The ankles tend to touch while the knees are apart.

Front 3

Genu recurvatum

Back 3

Called "back knees" is the positioning of the tibiofemoral joint in which range of motion goes beyond 0 degrees of extension

Front 4

Patellar tendonitis

Back 4

Or jumper's knee, is characterized by tenderness at the patellar tendon and results from the overuse stress or sudden impact overloading associated with jumping.

Front 5

Osgood- Schlatter disease

Back 5

Is a common overuse injury among adolescents. It involved the traction-type epiphysis on the tibial tuberosity of growing bone where the tendon of the quadriceps muscle attaches.

Front 6

Popliteal cyst

Back 6

Or Baker's cyst, is actually misnamed as a "cyst" this general term refers to any synovial hernia or bursitis involving the posterior aspect of the knee.

Front 7

Patellofemoral Pain Syndrome

Back 7

Generally refers to a common problem causing diffuse anterior knee pain, quadriceps weakness or tightness, weakens of hip lateral rotators and excessive foot probation.

Front 8

Chondromalacia Patella

Back 8

Is the softening and degeneration of the cartilage on the posterior aspect of the patella, causing anterior knee pain.

Front 9

Prepatellar Bursitis

Back 9

"Housemaid's knee" occurs when there is constant pressure between the skin and the patella. It is commonly seen is carpet layers and is the result of repeated direct blows or sheering stresses on the knee

Front 10

Terrible triad

Back 10

Is a knee injury caused by a single blow to the knee and involves tears to the anterior cruciate ligament, the medial collateral ligament, and the medial meniscus.

Front 11

Miserable malalignment syndrome

Back 11

Is an alignment problem of the lower extremity involving increased anteversion of the femoral head and is associated with genu valgus, increased tibial torsion, and pronated flat foot.
