X-shaped inferior extensor retinaculum and its doubtful use in the Bröstrom-Gould procedure.

Knee Surg Sports Traumatol Arthrosc 2018 Jul 14;26(7):2171-2176. Epub 2017 Jul 14.

Human Anatomy Unit, Department of Pathology and Experimental Therapeutics, School of Medicine, University of Barcelona, C/FeixaLlarga, s/n, 09806, Hospitalet de Llobregat, Barcelona, Spain.

Purpose: The inferior extensor retinaculum (IER) is an aponeurotic structure located in the anterior aspect of the ankle. According to the literature, it can be used to reinforce a repair of the anterior talofibular ligament in ankle instability. Despite its usual description as an Y-shaped structure, it is still unclear which part of the retinaculum is used for this purpose, or if it is instead the crural fascia that is being used.

The Role of Medial Patellofemoral Ligament Repair and Imbrication.

Am J Orthop (Belle Mead NJ) 2017 Mar/Apr;46(2):87-91

Department of Orthopaedics and Rehabilitation, University of Iowa Hospitals and Clinics, Iowa City, IA.

Repair, reefing, and advancement of the medial patellofemoral ligament (MPFL) and medial retinacular structures can be performed as an isolated procedure or in conjunction with distal realignment procedures for patients with patellar instability. Although various operative techniques have been described, understanding the appropriate clinical indications and MPFL injury patterns ultimately determines the success or failure of the procedure. MPFL repair is best indicated in the acute setting, particularly if there is a patella- or femoral-based avulsion. Read More

Quantitative histological grading methods to assess subchondral bone and synovium changes subsequent to medial meniscus transection in the rat.

Connect Tissue Res 2017 May - Jul;58(3-4):373-385. Epub 2016 Oct 31.

a J. Crayton Pruitt Family Department of Biomedical Engineering , University of Florida , Gainesville , FL , USA.

Aim Of The Study: The importance of the medial meniscus to knee health is demonstrated by studies which show meniscus injuries significantly increase the likelihood of developing osteoarthritis (OA), and knee OA can be modeled in rodents using simulated meniscus injuries. Traditionally, histological assessments of OA in these models have focused on damage to the articular cartilage; however, OA is now viewed as a disease of the entire joint as an organ system. The aim of this study was to develop quantitative histological measures of bone and synovial changes in a rat medial meniscus injury model of knee OA. Read More

A novel rabbit model of early osteoarthritis exhibits gradual cartilage degeneration after medial collateral ligament transection outside the joint capsule.

Sci Rep 2016 10 19;6:34423. Epub 2016 Oct 19.

Institute of Sports Medicine, Beijing Key Laboratory of Sports Injuries, Peking University Third Hospital, 49 North Garden Road, Haidian District, Beijing 100191, People's Republic of China.

Though many surgical animal models have been used to induce osteoarthritis (OA) of the knee joint, they always open the capsule of the joint. Any surgical procedures that incises the capsule may cause inflammation, pain, and possibly altered gait. One common disadvantage of these surgically induced animal models is that they may affect the initial structures and synovial fluid in joint. Read More

Department of Orthopedics and Traumatology, Okmeydanı Training and Research Hospital, Istanbul, 34384, Turkey.

Proprioceptive inputs from the joints and limbs arise from mechanoreceptors in the muscles, ligaments and tendons. The knee joint has a wide range of movements, and proper neuroanatomical organization is critical for knee stability. Four ligaments (the anterior (ACL) and posterior (PCL) cruciate ligaments and the medial (MCL) and lateral (LCL) collateral ligaments) and four tendons (the semitendinosus (STT), gracilis (GT), popliteal (PoT), and patellar (PaT) tendons) from eight fresh frozen cadavers were harvested.
