In medicine and sports medicine, knee injuries are "injuries to the knee or the knee joint".[1]
Fractures
The Ottawa knee rule, a clinical prediction rule, can guide need for an x-ray:[2]
- age 55 years or older
- "isolated tenderness of patella (no bone tenderness of knee other than patella)"
- "tenderness at head of fibula"
- "inability to flex 90 degrees"
- "inability to bear weight both immediately and in the emergency department for 4 steps (unable to transfer weight twice onto each lower limb regardless of limping)"
Torn meniscus or ligament
Many tests have been proposed to improve the physical examination. Examples are:
The presence of any effusion indicates likely injury to a meniscus or ligament.[3]
The presence of a hemarthrosis indicates likely injury to a meniscus or ligament, usually of the anterior cruciate ligament with high specificity.[4]
Meniscal injuries
- Diagnosis: Apley compression, McMurray's, and medial-lateral grind tests.
- Treatment: When to surgically repair anterior cruciate ligaments is not clear.[5]
Cruciate ligaments injuries
- Anterior drawer, posterior drawer, lateral pivot shift, and Lachman tests. Injuries to the cruciate ligaments can be accurately diagnosed with physical examination by orthopedic physicians; meniscal injuries are more difficult to detect.[6] No sign on the physical examination (McMurray's, Apley's, and joint line tenderness) is more than 70% sensitive for meniscal injuries.[7]
When to surgically repair anterior cruciate ligaments is not clear.[8]
Sports medicine
Knee injuries are common in sports, certainly contact sports such as American football, in which two 300-pound men may strike opposite sides of the same leg, but also in individual events requiring explosive effort with the knee. Advanced dancers can have very similar injuries; it is no coincidence that professional football players may study ballet to improve their coordination.
