Imaging finding and arthroscopic treatment of isolated contracture of the rectus femoris muscle: a case report
Isolated rectus femoris (RF) contracture is encountered very rarely in orthopaedic practices. There are few reports on its imaging manifestations and no cases reported to be treated with arthroscopy.
ConclusionsCutting the deep fibres of the ITB caused large increases in tibial internal rotation laxity across the range of knee flexion, while cutting the ALL alone did not. With ACL deficiency combined with anterolateral deficiency, ACL reconstruction alone was insufficient to restore native knee rotational laxity. However, combining a ‘monoloop’ lateral extra-articular tenodesis with ACL reconstruction did restore native knee laxity.

Utilizing the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and QUORUM (Quality of Reporting of Meta-Analyses) protocol, a systematic search identified and analyzed the published literature pertaining to...
Publication date: Available online 23 January 2020Source: Journal of Arthroscopy and Joint SurgeryAuthor(s): L. Nugent, H. MumtazAbstractThe formation of pseudoaneurysms secondary to ankle arthroscopy is relatively uncommon (only twenty-three cases having been reported in the literature at a 2019 systematic review), the tibialis anterior and dorsalis pedis vessels being most commonly affected. Here is presented such a case, which has unusually occurred following an otherwise uncomplicated arthroscopically-assisted arthrodesis, a potential mechanism speculated upon, and suggestions for how to avoid such undesirable outcomes given.
We describe an arthroscopic sign of an unstable medial meniscal tear that is diagnostic. The “crevice sign” is a longitudinal fissure located on the distal medial femoral condyle. In the anterior cruciate ligament–deficient knee, there is increased strain on the medial meniscus. A posterior longitudinal medial meniscal tear can occur at the time of the index injury or with subsequent instability events. During this injury, the knee pivots and the anterior edge of the unstable medial meniscus digs into the articular cartilage of the medial femoral condyle, resulting in a longitudinal split of the distal fe...
Publication date: Available online 22 January 2020Source: Arthroscopy TechniquesAuthor(s): Christian Fink, Robert Smigielski, Rainer Siebold, Elisabeth Abermann, Mirco HerbortAbstractAccording to recent anatomic studies, the anterior cruciate ligament (ACL) appears to be a flat, “ribbon-like” structure, with a thin, oval-shaped insertion on the femur and a C-shaped tibial insertion. According to this anatomy, we describe an ACL-reconstruction technique that aims to approximate this natural anatomy. The basic principle of this technique is not to use conventional round tunnels but create tunnel shapes that resem...
We describe a technique using a fascia lata autograft to reconstruct the rotator cuff in the setting of a massive cuff tear. This is of particular importance in centers that lack the funding or institutional approval to use acellular dermal allografts that have been popularized to date.
We present a technique that incorporates a cross-linked suture tape into either a palmaris longus or gracilis tendon autograft or allograft for ulnar collateral ligament reconstruction. This may allow for a biomechanically stronger construct because it appears this is the case in other settings. The goal is that this would lead to decreased rates of failure or possibly allow athletes to return at an accelerated rate.
This article describes this treatment using an alternative superomedial portal and modified chicken-wing position to improve access to the scapulothoracic space and thus perform the procedure as safely as possible, with less morbidity and excellent results for the patients.
We describe a technique of hamstring autograft harvesting using only 2 anatomic references that makes it a simple and reproducible technique for surgeons, especially those in training.
We describe the utilization of arthroscopic anatomic glenoid reconstruction using a distal tibial allograft after a failed Latarjet procedure. Preoperative and operative methodology are described with relevant imaging investigations and a detailed intraoperative arthroscopic technique.
