Rupture of the anterior cruciate ligament ACL injury by beating bell.

Print Article

The ACL injury by beating bell

The rupture of the anterior cruciate ligament (ACL) in bell clapper is a rare ACL injury often overlooked.

Its diagnosis is clinical:

It is the presence of a flexion contracture of the knee (difficulty soft knee) often painful and irreducible. Usually present from the accident but sometimes after a free interval.


It is important to emphasize the role of MRI for radiological diagnosis with an aspect of "clapper" forward in the notch.


The treatment is always surgical. It involves removal of the ACL stump (clapper) by arthrolysis sub-arthroscopy associated with an ACL graft in the same operation (hamstring or KJ).

There is no proper epidemiological factor to damage the anterior cruciate ligament in bell clapper. Few studies in the literature available on the subject. The only epidemiological factor found in the literature is the frequency of partial ACL tears.
