Isolated posterolateral corner injury is an uncommon injury that could be a source of unexplained knee pain and dysfunction. Most of these patients present instability caused by concomitant ligament injuries. Numerous studies have shown open approach posterolateral repair or reconstruction surgeries to restore posterolateral rotational stability. Still, there is a certain population of patients who present posterolateral rotation instability without significant injury to the fibular collateral ligament, popliteal fibular ligament, and popliteus tendon. The posterolateral capsular ligament is critical to provide posterolateral rotation stability. In this Technical Note, with video, we show a completely arthroscopic approach to stabilize the posterolateral corner, by stabilizing the posterior lateral joint capsule with the lateral meniscus attached to the rim of the lateral tibial plateau.

“…The popliteomeniscal fascicles (PMF) are posterolateral meniscocapsular extensions that blend inferiorly into the popliteus musculotendinous region and allow the tendon to pass from an intra-articular to an extra-articular compartment while maintaining the compartmental integrity of the knee joint [1,2].…”

Natural evolution of popliteomeniscal fascicle tears over 2 years and its association with lateral articular knee cartilage degeneration in patients with traumatic anterior cruciate ligament tear. Abstract Objectives To assess (i) normal imaging anatomy of the popliteomeniscal fascicles, (ii) prevalence and natural evolution of popliteomeniscal fascicle tears (PMFT) in subjects with traumatic anterior cruciate ligament (ACL) tears over 2 years and (iii) compare knee cartilage degeneration in subjects with and without PMFT longitudinally. Methods 57 subjects with ACL tears were screened for PMFT. Morphological (high-resolution 3D fast spin-echo) and compositional (T1ρ and T2 mapping) MR imaging was performed prior to and 2 years after ACL reconstruction. Differences of morphological and compositional parameters were compared between subjects with and without PMFT using logistic regression, adjusting for age, sex and BMI.Results In 24% (n = 14) of the subjects with ACL tear a PMFT was detected on baseline MRI. One subject with PMFT developed a meniscal tear over 2 years. Cartilage ΔT1ρ of the lateral femur increased significantly more in subjects with isolated PMFT compared to controls (mean difference, 2.0 ± 2.9 vs. −1.3 ± 1.6, p = 0.027).Conclusion PMFT detected by MRI are a common finding in subjects with ACL tears. Subjects with these defects showed higher compositional cartilage deterioration compared to controls, over 2 years in the lateral femoral compartment, indicating accelerated cartilage degeneration. Key Points• Popliteomeniscal fascicle lesions are a common finding in subjects with ACL tears.• Progression to a meniscal tear over 2 years is not frequent.• Anteroinferior popliteomeniscal fascicle is injured most frequently.• Patients with popliteomeniscal fascicle lesions showed accelerated cartilage degeneration.
