The associated lesion of the posterior oblique ligament (POL) in the setting of anterior cruciate ligament rupture is quite frequent due to the same rotational mechanism. The diagnosis of POL lesions is challenging, and physical examination is delicate; moreover, they can be easily missed on magnetic resonance imaging. Once recognized, POL lesions must be repaired to restore posteromedial corner kinematics. The aim of this Technical Note is to present a safe and effective method for POL repair in the set of an anterior cruciate ligament reconstruction., (© 2020 by the Arthroscopy Association of North America.

Chronic patellar tendinopathy remains a challenging problem. The first line of treatment is conservative; when this fails, surgical treatment is indicated. Several open and arthroscopic techniques have been described. We describe an alternative technique using ultrasound-guided electrocoagulation of neovessels that leaves the patellar tendon intact., (© 2020 by the Arthroscopy Association of North America.

Background: Meniscal root avulsion has been predominantly reported in an adult population but little is known about this meniscal lesion in children and adolescents., Purpose: The of this article is to describe the clinical symptoms and a new MRI sign of a medial meniscus posterior root avulsion in skeletally immature patients, and to report the arthroscopic procedure for its reinsertion in the presence of open physes., Case Description: We report two skeletally immature patients who had a medial meniscus posterior root avulsion [MMPRA]. Diagnosis of a MMPRA was suspected on MRI by intense T2 hypersignal located at the postero-medial part of the tibial plateau reflecting trabecular bone oedema ("Bone bruise") at the level of the medial meniscal posterior root attachment. Arthroscopic reduction and fixation of the posterior root of the medial meniscus with transosseous sutures was performed. The patients returned to sport at the end of 6 months without residual symptoms. At one year, the radiographs showed no modification of the physis. Healing of the medial meniscal posterior root was noted on MRI., Clinical Relevance: In a skeletally immature patient it is important that this rare meniscal lesion is diagnosed early and adequately treated. We emphasize the importance of the indirect MRI signs that can lead a clinician to suspect the diagnosis of MMPRA. The aim of the surgery was to restore the anatomical footprint of the meniscal root and to re-establish its function thus preventing future chondral damage without damage to the tibial physeal growth plate., Level of Evidence: Level IV., (Copyright © 2014 Elsevier B.V.
