BACKGROUND We 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 valu...

Background:  Parts of the implants placed over the meniscus during meniscal repair can wear down the cartilage in the contact zones and cause chronic synovitis. Placing horizontal sutures under the meniscus may overcome this potential hazard. The purpose of this prospective study was to evaluate the midterm results of arthroscopic meniscal repair using submeniscally placed out-in horizontal sut...

OBJECTIVES  To compare patient reported outcomes from before surgery to 52 weeks after surgery between individuals undergoing arthroscopic partial meniscectomy for traumatic meniscal tears and those for degenerative meniscal tears. DESIGN  Comparative prospective cohort study. SETTING  Four public orthopaedic departments in the Region of Southern Denmark. Participants were recruited between...

We hypothesised that meniscal tears treated with mesenchymal stem cells (MSCs) together with a conventional suturing technique would show improved healing compared with those treated by a conventional suturing technique alone. In a controlled laboratory study 28 adult pigs (56 knees) underwent meniscal procedures after the creation of a radial incision to represent a tear. Group 1 (n = 9) had a...

The double popliteus tendon sign is seen on sagittal magnetic resonance imaging (MRI) of the knee as a low-signal-intensity band parallel to the popliteus tendon at the level of the popliteus hiatus. It is the result of a displaced complex flap tear of the lateral meniscus. This type of displaced meniscal tear can be easily missed on MRI, unless the clinician is aware of its existence and signi...

This case involves a unique reverse Segond fracture pattern with ACL and MCL tears that does not have the usually involved PCL tear or obvious meniscal tear. It further shows the importance of recognition of the medial tibial avulsion fracture as an indicator of more severe internal derangement and instability of the knee. Early recognition prompts a more thorough evaluation and management of i...

The incidence of meniscal tear injuries is rising, predominately due to the sporting activities young adults. There are different methods in orthopedics management. An Arthroscopic Partial Meniscectomy (APM) most practiced orthopedic procedure globally. However, recent literature reported serious concerns about its positive outcome. Meniscal repair another recommended technique and growing rapi...

The occurrence of posterior root tear of both the lateral and medial menisci, combined with anterior cruciate ligament rupture, is rare. Problems may be encountered such as the difficulty to access the medial meniscal root tear, the confusing circumstances about which structure to repair first, and the possibility of the tunnel for each repair to become taut inside the tibial bone. We present t...

OBJECTIVE To prospectively investigate the healing process of meniscal repair with plain magnetic resonance imaging (MRI) and indirect MR arthrography and to compare the two methods. MATERIALS AND METHODS Twenty patients with an arthroscopic meniscal repair without clinical symptoms underwent conventional and indirect MR arthrography of the affected knee, 3, 6 and 12 months after the index op...

Dear Editor, The menisci are important tissues in the healthy knee due to their shock absorption and load distribution properties. Meniscal tears are important clinically due to pain and swelling and the mechanical symptoms they cause such as locking. The arthroscopic anatomical classifi cation of meniscal tears was described by Dandy in 1990.1 In the paper, he noted that the majority (69%) of ...
