Summary

AAFont SizeShareMore Information
Knee injuries are among the most reported sports injuries.[1] [2] [3] A 2017 study reported that the knee is the third most common site of ligamentous injuries.[4] Many can be treated conservatively with rest, ice, immobilization, and physical therapy. The aim of initial assessment is to identify any neurological or vascular compromise, which could require urgent surgery, then to establish the likely nature of the injury through a focused history and examination.

Acute knee injuries

By most definitions, acute knee injuries are defined as being diagnosed within the first 30 to 42 days of the injury or onset of symptoms.

Chronic knee injuries

Chronic knee injuries are due to residual old trauma or surgery, existing degenerative diseases, or previous conditions not resolved within the first 30 to 42 days after the onset.
