“…The transverse ligament and ACL can also be the origins. 65 Anterior lateral cysts extended medially either into the root or into the Hoffa fat pad, but in some cases, the type of extension did not correlate with the presence of an underlying meniscal tear. 54 Zheng et al 249 reported that preoperative anterior horn cysts showed worse patient-reported outcomes.…”

Background: The lateral meniscus is a unique structure of the knee joint, and its anatomy, function, pathological process, and treatment are distinct from those of the medial meniscus. To date, no consensus on the management of lateral meniscal lesions has been published, and clinical decision-making is challenging. To facilitate this, consensus and practice guidelines for lateral meniscal lesions were developed and endorsed by the Chinese Society of Sports Medicine. Study Design: Consensus statement. Methods: This project followed the Delphi approach to the consensus process, involving steering, rating, and peer review groups. A total of 61 experts in the fields of sports medicine and arthroscopic surgery were invited to participate in the compilation of a consensus statement on lateral meniscal lesions. (The discoid lateral meniscus was addressed by separate consensus.) To begin, the steering group drafted a set of questions and replies regarding lateral meniscal lesions. An online panel discussion was then held to provide initial agreement and comments on the statements, followed by a round of anonymous voting. Results and feedback were sent to the steering group for a second draft. A second round of voting was then held, and each statement was discussed during a combined meeting of the steering and rating groups. Finally, a consensus draft was evaluated by a review group. Results: Fifty-three questions and answers addressing lateral meniscal lesions were drafted, and 20 statements were excluded because of redundant information during the first round of voting. Ultimately, 33 statements were completed, 9 of which were unanimous. Conclusion: This expert consensus process focused on the anatomy, function, pathological processes, and treatment of lateral meniscal lesions. Accepted recommendations in these areas can assist doctors and therapists in standardizing the management of related pathology. The consensus statement indicates that certain types of lateral meniscal tears that were previously considered irreparable can be repaired. Preservation of the lateral meniscus should be the first-line treatment whenever possible, because the long-term clinical and radiological outcomes are worse after partial meniscectomy.

“…Macerated tear is closely associated with meniscus cyst which is mostly found between the AHLM and the anterior cruciate ligament [ 13 ]. Differing from the even network structure of meniscus body and posterior horn, the circumferential fibers of AHLM gather to be bundles, and the loose separation between circumferential fiber bundles generate micro gap.…”

BackgroundWe describe a special, interesting phenomenon found in the anterior horn of the lateral meniscus (AHLM): most tear patterns in the AHLM are distinctive, with loose fibers in injured region and circumferential fiber bundles were separated. We name it as macerated tear. The goal of this study was to bring forward a new type of meniscal tear in the AHLM and investigate its clinical value.Materials and MethodsAHLM tears underwent arthroscopic surgery from January 2012 to December 2014 were included. Data regarding the integrity of AHLM were prospectively recorded in a data registry. Tear morphology and treatment received were subsequently extracted by 2 independent reviewers from operative notes and arthroscopic surgical photos.ResultsA total of 60 AHLM tears in 60 patients (mean age 27.1 years) were grouped into horizontal tears (n = 15, 25%), vertical tears (n = 14, 23%), complex tears (n = 6, 10%), and macerated tears (n = 25, 42%). There were 6 patients with AHLM cysts in macerated tear group and one patient in vertical tear group. 60 patients were performed arthroscopic meniscus repairs and were followed-up with averaged 18.7 months. Each group had significant postoperative improvement in Lysholm and IKDC scores (p < 0.05). However, the macerated tear group showed least functional recovery of Lysholm and IKDC scores compared to other groups (p < 0.05). In addition, there were no differences in postoperative range of motion, return to work, or return to sport/other baseline activities between the four groups (p > 0.05).ConclusionsThis study demonstrated that the macerated tear is common in the tear pattern of AHLM. However, feasibility of the treatment of this type of meniscal tear, especially the meniscus repairs still requires further study.

Cysts of the anterior horn lateral meniscus and the ACL: is there a relationship?

Abstract: Our results suggest that cysts adjacent to the AHLM may in part be explained by cysts or ganglia of the ACL.
