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

ABSTRACT: 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.

Project description:PurposeTo describe double radial tears of the lateral meniscus (LM), report early clinical treatment outcomes, and determine reoperation and failure rates.MethodsTwenty-one (N = 21) consecutive cases of arthroscopic-treated lateral meniscus double radial tears treated between 2012 and 2018 were reviewed, including 15 males (71.4%) and 6 females (28.6%). Meniscus repairs were all performed at the time of anterior cruciate ligament (ACL) reconstruction. Patients with associated fractures or prior surgeries were excluded. Concomitant injuries were reported, as were preinjury and postoperative Tegner scores, preoperative and postoperative visual analogue pain scale (VAS) scores, and postoperative International Knee Documentation Committee (IKDC) subjective scores. Reoperation and failure rates were documented.ResultsTwenty-one (N = 21) tears were located in the posterior horn of the meniscus near the root attachment; 15 (71.4%) underwent all-inside repair, 4 (19.0%) underwent transtibial pull-through repair, 1 (4.8%) was partially debrided, and 1 (4.8%) was left untreated. Twenty-one tears (N = 21) were in the body of the meniscus; 7 (33.3%) were repaired, 7 (33.3%) were partially debrided, and 7 (33.3%) were left untreated. Thirteen patients (62%) had associated medial collateral ligament (MCL) injuries. Mean follow-up was 2.6 years. VAS at rest and with activity improved by 2.1 points (P < .001) and 3.1 points (P = .017) after surgery. The mean postoperative Tegner activity score was 6.4, and the mean IKDC score was 83.2 at final follow-up. Reoperation was required in 5 patients (23.8%), and the surgical treatment failed in 1 patient (4.7%).ConclusionsDouble radial tears of the LM are uncommon injuries that occur in the setting of ACL tears, usually combined with MCL injury. The variety of surgical treatment techniques have a low failure rate at short-term follow-up. Patients tend to have good clinical outcomes with improvement in pain and overall function after surgically treating these injuries with simultaneous ACL reconstruction.Level of evidenceLevel IV, therapeutic study, case series.
