Immediately below its origin is the groove for the tendon of the Popliteus.
The greater part of its lateral surface is covered by the tendon of the
Biceps femoris; the tendon, however, divides at its insertion into two
parts, which are separated by the ligament.
Deep to the ligament are the tendon of the Popliteus, and the inferior lateral genicular vessels and nerve.Doctor Christopher Zarembinski
higher grade tears of the MCL with ongoing instability, the MCL can be
sutured or replaced. Other non-surgical approaches for more severe MCL
injuries may include prolotherapy, which has been shown by Reeves in a
small RCT to reduce translation on KT-1000 arthrometer versus placebo.
The future of non-surgical care for a non-healing MCL injury with laxity
(partial ligament tear) is likely bioengineering. Fan et al. (2008)
have demonstrated that knee ligament reconstruction is possible using
mesenchymal stem cells and a silk scaffold.
The lateral meniscus is less likely to be injured or torn than the
medial meniscus. Diagnosis of lateral meniscus tear is done with
McMurray's test. If a tear is detected, treatment depends on the type
and size of the tear. Small tears can be treated conservatively, with
rest, ice, and pain medications until the pain is under control, then
exercise may be started with gradually increasing intensity, to improve
range of motion and decrease swelling. More severe tears of the lateral
meniscus require surgical repair or removal, which can often be done
arthroscopically. Swelling and stiffness of the knee can occur when you
have a torn lateral meniscus.Dr Christopher Zarembinski
The lateral meniscus, also called the external semilunar fibrocartilage,
is a fibrocartilaginous band that spans the lateral side of the
interior of the knee joint. It is one of two menisci of the knee, the
other being the medial meniscus. It is nearly circular and covers a
larger portion of the articular surface than the medial. It can
occasionally be injured or torn by twisting the knee or applying direct
force, as seen in contact sports.

It is fused with the tibial collateral ligament which makes it far less
mobile than the lateral meniscus. The points of attachment are
relatively widely separated and, because the meniscus is wider
posteriorly than anteriorly, the anterior crus is considerably thinner
than the posterior crus. The greatest displacement of the meniscus is
caused by external rotation, while internal rotation relaxes it.
