“…The patient is then encouraged to walk with full weight bearing on the knee joint after the correct position of the lateral meniscus is verified on MRI. Reposition of the posterior segment of the lateral meniscus can push the popliteus tendon off the LTP to the normal position, which makes meniscocapsular suture [ 5 , 6 ] possible. Active flexion exercise of the knee joint is started after the plaster cast is removed.…”

We report a case of bilateral, permanent subluxation of the lateral meniscus. To our knowledge, the present case is the first reported description of bilateral irreducible anterior dislocation of the posterior segment of the lateral meniscus. This disorder is characterized by a flipped meniscus sign of the lateral meniscus on sagittal magnetic resonance images of the knee joint, with no history of trauma or locking symptoms. A detailed examination of serial magnetic resonance images of the lateral meniscus can help differentiate this condition from malformation of the lateral meniscus, that is, a double-layered meniscus. We recommend two-stage treatment for this disorder. First, the knee joint is kept in straight position for 3 weeks after the lateral meniscus is reduced to the normal position. Second, if subluxation of the lateral meniscus recurs, meniscocapsular suture is then performed. Although subluxation of the lateral meniscus without locking symptoms is rare, it is important to be familiar with this condition to diagnose and treat it correctly.

“…The current treatment options for RSLM are meniscectomy, 2 coronary ligament and meniscocapsular repair, [2][3][4][5][6][7] and thermal shrinkage of the posterolateral capsule. 8,9 However, 11% to 33% of patients who undergo coronary ligament and meniscocapsular repair or thermal shrinkage of the posterolateral capsule have recurrence of knee locking.…”

“…1 Therefore, we have called this condition RSLM only at deep flexion (RSLMdf). To date, the treatments described for RSLM are meniscectomy, 2 coronary ligament and meniscocapsular repair, [2][3][4][5][6][7] and thermal shrinkage of the posterolateral capsule. 8,9 However, all of these have disadvantages.…”

Reconstruction of the Popliteomeniscal Fascicles for Treatment of Recurrent Subluxation of the Lateral Meniscus

Recurrent subluxation of the lateral meniscus is characterized by episodes of mechanical locking of the knee joint. To completely preclude the posterior segment of the lateral meniscus from undergoing anterior dislocation during deep knee flexion, the structures to which it is attached need to be relatively taut. The posterosuperior popliteomeniscal fascicle retains its tension during deep knee flexion; therefore, reconstruction of the posterosuperior and anteroinferior popliteomeniscal fascicles was performed with an autograft harvested from the iliotibial band. This technique provides stabilization of the posterior segment of the lateral meniscus during deep knee flexion without interfering with the normal movement of the lateral meniscus throughout the range of motion of the knee joint.

“…Le diagnostic peut être fait en arthroscopie en reproduisant la subluxation du segment postérieur du ménisque latéral. Cependant, seulement quelques études [1][2][3][4][5][6][7][8][9][10][11] ont signalé cette entité, et les caractéristiques physiopathologiques et cliniques de la SRML n'ont pas encore été entièrement élucidées. Anatomiquement, le segment postérieur du ménisque laté-ral est relativement mobile par rapport à celui du ménisque médial mais la racine reste bien fixée.…”

“…Elles peuvent entraîner des blocages itératifs lorsque la partie mobile se luxe sous le condyle. Elles ont été décrites de façon relativement récente dans la littérature, sans que la physiopathologie ne soit complètement identifiée [1][2][3][4][5][6][7][8][9][10][11].…”

Locking knee caused by subluxation of the posterior horn of the lateral meniscus

Abstract: The authors report a case of repetitive locking knee caused by a subluxation of the posterior horn of a normal lateral meniscus. The posterior horn was sutured to the posterior knee capsule and the athlete resumed complete sports activity 4 months after the surgery.
