Arthroscopy portals

Endoscopic repair of hamstring tears is well described in the literature, but endoscopic management for significantly retracted hamstring tears is not well described. Currently, repairing a hamstring tendon that has retracted 8 cm or more from the footprint on the ischial tuberosity is performed as an open procedure. The technique described here details endoscopic repair of retracted hamstring tears using a suture pulley mechanism and an inferomedial portal.

Arthroscopic visualization and access of the posterior knee are limited when using standard anterior and posterior portals. The creation of a trans-septal portal allows for complete access to the posterior compartment as arthroscopic instruments are able to be passed back and forth between the posteromedial and posterolateral compartments. Due to the close proximity of the popliteal artery and its branches, precise portal placement and safe orientation of arthroscopic instruments are critical to avoid iatrogenic injury...

Arthroscopic surgery for the posterior compartment in elbow has been used in the treatment of many pathologies. The direct posterior portal has been commonly used for this compartment. However, this portal involves penetrating the triceps brachii tendon responsible for extensor mechanism. This can possibly lead to poor performance during recovery and portal wound sensation with scar formation. An accessory posterolateral portal can be used as a substitute with adequate viewing and working space in all areas of the posterior compartment...

The complication rate of ankle arthroscopy (AA) ranges from 3.5% to 14%. To avoid such complications, it is essential to have a thorough understanding of the anatomy of the ankle, to perform the procedure very carefully and with appropriate instrumentation, and to use a non-invasive distraction technique. The most frequent complications are neurological (cutaneous nerve injuries), which are usually caused by direct injury during arthroscopic portals or by a distracting pin when using an invasive distraction technique...

INTRODUCTION: Osteochondrosis dissecans (OCD) at the capitellum is a common pathology in young patients. Although arthroscopic interventions are commonly used, there is a lack of information about the accessibility of the defects during elbow arthroscopy by using standard portals. MATERIALS AND METHODS: An elbow arthroscopy using the standard portals was performed in seven fresh frozen specimens. At the capitellum, the most posterior and anterior cartilage surface reachable was marked with K-wires...

During wrist arthroscopy, the wrist joint can be visualized from almost every perspective through a combination of standard dorsal and volar arthroscopic portals. This cadaveric study aims to compare all wrist portals described in terms of their safety in order to rank them according to the distance from the nearest structure at risk for arthroscopic wrist procedures. Twenty-nine cadaveric formalin-embellished upper limbs were examined. Needles were inserted at dorsal and volar portal sites to perform the measurements...

Fractures around the elbow are often challenging to treat and in most cases require an extensive approach. Since the development of elbow arthroscopy, most authors have pointed out the potential advantages of a less invasive technique that can be useful for visualization and reduction of the articular fragments with an eventual percutaneous fixation. Arthroscopic techniques provide a limited exposure that may lead to a faster wound healing, lower rate of complications and thus, better recovery of range of motion...

This cross-sectional study aimed at exploring the frequency and extent of knee joint lesions associated with delayed treatment of anterior cruciate ligament (ACL) injury. It enrolled 300 patients from 2020 to 2022 who were subjected to arthroscopy for anterior cruciate ligament reconstruction. The sample was comprised of Iraqi adult male patients from different regions of Iraq, and the surgical procedure was carried out in Al-Diwaniyah Teaching Hospital. The findings were recorded by Karl Storz's camera system...

Arthroscopic techniques for anterior talofibular ligament (ATFL) reconstruction have been developed in recent years. Allograft tendons are often used in ATFL reconstruction, and surgical indications include an insufficiently strong ligament remnant, high-demand activities, repeated ankle sprains, and revision cases. We describe a socket-anchor technique for talar tunnel creation: A 10-mm-deep bone tunnel (socket) is created along a previously located guidewire at the ATFL talar footprint; an absorbable suture anchor is inserted into the end of the socket; and the graft is tied to the suture, pulled into the socket, and finally, secured using an arthroscopic knot pusher...

Osteochondral fracture of the glenoid can be caused by traumatic damage in the shoulder, and addressing this injury can be challenging due to the complexity of the condition and the various treatment options. Left untreated, this injury can lead to post-traumatic arthritis and shoulder instability. There have been different surgical techniques for addressing osteochondral fracture, including open and arthroscopic methods, such as debridement, screw fixation, and bone graft, but there is a lack of a universally accepted treatment guidelines...

Knee arthroscopy is a minimally invasive surgical technique that allows surgeons to diagnose and treat various knee conditions using much smaller incisions than open surgery. However, it is difficult to fully visualize the posterior compartment of the knee joint using the usual anterior portal approach because of blind spots. The transseptal portal technique enables surgeons to visualize the surgical field and access instruments in the posterior compartment of the knee during arthroscopic surgery. However, creation of the posterior transseptal portal increases the risk of neurovascular injury...

PURPOSE: To evaluate whether elbow instability due to lateral collateral ligament complex injury can be assessed reliably through arthroscopy. METHODS: Eight fresh human cadaveric elbows were placed in a simulated lateral decubitus position. The radiocapitellar joint (RCJ) gap and ulnohumeral joint (UHJ) gap (mm) were measured with different sizes of probes from the posterolateral viewing portal. The elbow was 90 degrees flexed with neutral forearm rotation for RCJ gap measurement and 30 degrees flexed with full supination for UHJ gap measurement...

While the insertion of the arthroscope into the elbow joint is relatively easy based on anatomical landmarks, obtaining a correctly located instrument portal is often difficult. Therefore, the goal of the study was to create a 3D-printed prototype of an aiming device for the guiding needle, and to check its feasibility. The study included fresh cadavers of 15 dogs, 9 males and 6 females, aged from 1 to 6 years (median 4 years) with body weight from 17 to 57 kg (median 30 kg). On each dog, we compared the number of attempts needed to obtain optimal direction of the guiding needle for the portal, using one elbow the prototype, and performing this as control on the opposite joint without the prototype (with a free hand)...

PURPOSE: The purpose of this study was to evaluate patient outcomes and satisfaction after arthroscopic portal closure with absorbable versus nonabsorbable sutures after knee arthroscopy. METHODS: Patients undergoing primary knee arthroscopy were identified during procedure scheduling. Exclusion criteria included revision procedures, concomitant ligament reconstruction, or meniscal repair surgery. Before surgery, enrolled patients were randomly assigned to undergo closure with either 3-0 Monocryl absorbable or 3-0 nylon non-absorbable sutures...

BACKGROUND/OBJECTIVE: Arthroscopic lateral ligament repair (ALLR) for chronic lateral ankle instability (CLAI) has been improving with technical innovations. However, there is a lack of information regarding mid- and/or long-term clinical outcomes after the introduction of ALLR. This study aimed to report mid-term clinical outcomes of ALLR with a knotless anchor. METHODS: Thirty-two patients (11 men and 21 women; mean age, 28 ± 14 years) who underwent ALLR with a knotless anchor from December 2015 to October 2020 were included...

BACKGROUND: To assess the clinical and functional outcomes of all-inside arthroscopic anatomical repair of anterior talofibular ligament (ATFL) for management of chronic lateral ankle instability (CLAI) in a considerable number of patients during medium-term follow-up. METHODS: A retrospective analytic study was performed on 100 patients with CLAI who presented between August 2015 and July 2020 (average age: 32.9 years; range: 16-54 years). All-inside arthroscopic ATFL direct repair was performed in all patients through 2 portals only with fixation using 2 knotless anchors...

Bone-patellar tendon-bone (BTB) is a graft material used in anterior cruciate ligament (ACL) reconstruction. We describe creating a femoral tunnel using an inside-out posteromedial (PM) portal technique during anatomic double-bundle ACL reconstruction with a hamstring graft. We hypothesized that applying this femoral tunnel creation method to the revision ACL reconstruction using BTB would enable reconstruction in 1 stage. In this technique, an anteromedial, an anterolateral, and a PM portal are created to confirm the original ACL footprint and location and direction of the bone tunnel during primary reconstruction...

Ulnar bursa of the hand invaginates the flexor digitorum superficialis and flexor digitorum profundus tendons of the little, ring, long, and index fingers. Distension of this bursa can have an inflammatory or infective cause. It can also originate from pathology of another site (e.g., degenerative wrist joint). Because of the tough overlying palmar aponeurosis, distended ulnar bursa can have swelling at a remote site. The distended ulnar bursa can also have compressive neuropathy to the ulnar nerve and median nerve...

Arthroscopic posterior bone block procedure using cortical screws has been reported since 2012 for management of recurrent posterior instability associated with bone defects. To avoid screw complications, we describe a full arthroscopic technique based on cortical button fixation. With 4 portals (posterior, poster lateral, anterior, and anterolateral), we use a specific glenoid guiding system (to perform 2 tunnels) and 2 cortical buttons fixation. With a specific glenoid guide, the iliac crest bone graft (ICBG) is secured to the posterior glenoid rim by fixation with 2 cortical buttons...
