The coronary ligaments (meniscotibial ligaments) anchor the peripheral margins of both menisci to the tibial plateau through short fibrous bands. They allow the menisci to translate posteriorly during knee flexion (posterior translation of approximately 5 mm medially and 11 mm laterally) while preventing excessive meniscal displacement. Coronary ligament sprain produces well-localised joint line pain without meniscal tear.

Anchor the peripheral margins of the menisci to the tibial plateau while allowing limited meniscal movement during flexion and extension.
Coronary ligament sprain is an underdiagnosed cause of knee joint line pain that follows a rotational knee injury without evidence of meniscal pathology on MRI. Tenderness lies at the meniscotibial junction just below the joint line, and pain is often reproduced by rotating the tibia. MRI showing coronary ligament oedema without meniscal signal supports the diagnosis. It usually settles with 6 to 8 weeks of conservative management and progressive rotational loading; persistent symptoms should raise suspicion of a peripheral meniscal tear.
Meniscotibial ligament injury producing joint line pain without meniscal pathology on MRI managed conservatively over 6 to 8 weeks.
