grade II sprain
Moderate ligament injury involving partial tearing of fibers with some joint instability but intact overall structure.
Full Definition
A moderate severity ligament injury classified as partial disruption of ligament fibers with mild to moderate joint instability. Grade II sprains represent the middle category in the three-grade classification system, falling between grade I (mild stretching without fiber disruption) and grade III (complete ligament rupture). Symptoms include moderate pain, swelling, bruising, and some functional limitation. Physical examination reveals mild joint laxity but a firm endpoint. Treatment typically involves protected weight-bearing, progressive strengthening, and functional rehabilitation over 3-6 weeks.
Usage
Usage note: Always specify anatomical location and use Roman numeral II; distinguish from muscle strains in documentation.
