: In wrist arthroscopy, the standard dorsal portals are the most commonly used. However, their placement can be associated with injuries to the neurovascular structures of the radiocarpal joint. The present study assessed and compared the distance of commonly used dorsal portals to radial and ulnar neurovascular structures. Forty patients (20 males, 20 females) were evaluated with T1-weighted spin-echo (SE) magnetic resonance (MR) sequences. We measured the distance between 1-2 and 3-4 portals and radial vascular bundle and the nearest branch of the superficial branch of radial nerve (SBRN)...

INTRODUCTION: The use of metatarso-phalangeal joint arthroscopy in the treatment of osteochondritis dissecans was first described in 1988. The technique produces good results. However, it can be difficult to enter a joint when it is deformed by degenerative disease. Sonography is a modern visualisation modality which can be used in orthopaedic surgery. AIM: To describe a method of intraoperative sonographic navigation during first metatarso-phalangeal joint arthroscopy...

: Intra-articular calcaneal osteoid osteoma is a very rare condition and the diagnosis as well as the treatment is extremely challenging. We report a case of a 19-year-old male with intra-articular osteoid osteoma of the calcaneus, initially treated for peroneal tenosynovitis with unsatisfactory results. Thorough diagnostic procedure revealed the superolateral location of a calcaneal osteoid osteoma, near the sinus tarsi. A cherry-red elevated lesion typical of an osteoid osteoma nidus was completely removed arthroscopically using the anterolateral portal and the middle portal for subtalar arthroscopy...

Posterior ankle impingement syndrome (PAIS) is a common injury in athletes engaging in repetitive plantarflexion, particularly ballet dancers and soccer players. Despite the increase in popularity of the posterior two-portal hindfoot approach, concerns with the technique remain, including; the technical difficulty, relatively steep learning curve, and difficulty performing simultaneous anterior ankle arthroscopy. The purpose of the current literature review is to provide comprehensive knowledge about PAIS, and to describe a systematic four-stage approach of the posterior two-portal arthroscopy...

Three direct volar portals for wrist arthroscopy have been described previously: two radiocarpal and one midcarpal. The aim of this study was to systematically describe four volar arthroscopic portals through minimally invasive incisions using an inside-out approach from known dorsal portals. Four volar arthroscopic wrist portals were studied on six hand specimens using an inside-out technique: a radial radiocarpal approach (RRCA), an ulnar radiocarpal approach (URCA), a radial midcarpal approach (RMCA) and an ulnar midcarpal approach (UMCA)...

Tanya Keough, David Wilson, Ivan Wong
Over the past 2 decades, hip arthroscopy has developed as a surgical technique, with more orthopaedic surgeons attempting to become proficient in performing this surgical procedure as indications and surgical skills evolve. The hip joint presents unique arthroscopic challenges because of its anatomic location, and it can be challenging to safely and confidently establish portal sites. Ultrasound-guided hip arthroscopy portal placement is not yet common practice for orthopaedic surgeons. The potential advantages of ultrasound-guided hip arthroscopy portal placement are the lack of radiation exposure to the patient and operating room personnel, direct visualization of the hip joint and surrounding soft-tissue structures, and lack of bulky fluoroscopic equipment in the operative field...

The use of an accessory posteromedial portal for posterior cruciate ligament reconstruction in bicruciate knee ligament reconstruction has often been described. However, the use of a posteromedial portal can be time consuming and has some inherent risks including injury to the saphenous vein or nerve. We describe our bicruciate knee ligament reconstruction using 4 exclusively anterior portals including a high anteromedial, high anterolateral, low anteromedial, and low anterolateral portals. Arthroscopy is performed using a combination of 30° and 70° arthroscopes...

Revision arthrodesis is indicated in symptomatic nonunion of the first tarsometatarsal joint. Revision by first tarsometatarsal arthroscopy cannot deal with the dilated screw tract and associated bone cysts. Revision by bone endoscopy is indicated in symptomatic nonunion of the first tarsometatarsal joint, which is previously fixed by transarticular screw along with loosening of the screw and bone cyst formation. The screw tract makes up the portal tract, with the proximal and distal ends of the tract corresponding to the proximal and distal portals, respectively...

BACKGROUND: Evolving wrist arthroscopy requires creating new portals, and creating portals reciprocally leads to increased indications for arthroscopic wrist procedures. To facilitate access to the lunate bone and fossa for new arthroscopic procedures, a new portal was used. This is a cadaveric study of this portal. OBJECTIVES: In this cadaveric study, we evaluated a portal in wrist arthroscopy for procedures involving the lunate bone and lunate fossa. MATERIALS AND METHODS: Seventeen wrists from 10 fresh cadavers were included in this study...

Introduction Pseudoaneurysm formation following ankle arthroscopy is a rare but potentially catastrophic complication. The placement of anterior ankle portals carries inherent risk to the superficial and deep peroneal nerves, as well as to the dorsalis pedis artery. Anatomical variations in the dorsalis pedis and the presence of branches at the joint line may increase the risk of vascular injury and pseudoaneurysm formation during arthroscopy. There is limited anatomical evidence available regarding the branches of the dorsalis pedis artery, which occur at the point at which they cross the ankle joint...

BACKGROUND: Prompt open arthrotomy is historically utilized to treat pediatric septic arthritis of the hip, but arthroscopy has been described as a valid alternative to prevent long-term sequelae. Standard hip arthroscopy in adolescents and adults utilizes lateral-based portals, but successful irrigation in infants may necessitate a medial portal due to the smaller joint size. The purpose of this study was to determine the safety of a medial hip portal in children based on its anatomic relation to neurovascular structures...

Hip arthroscopy in patients with osteoarthritis has been shown to have suboptimal outcomes. Elevated cytokine concentrations in hip synovial fluid have previously been shown to be associated with cartilage pathology. The purpose of this study was to determine whether a relationship exists between hip synovial fluid cytokine concentration and clinical outcomes at a minimum of 2 years following hip arthroscopy. Seventeen patients without radiographic evidence of osteoarthritis had synovial fluid aspirated at time of portal establishment during hip arthroscopy...

Hip arthroscopy has gained popularity in recent years for diagnostic and therapeutic hip preservation management. This article details the establishment of arthroscopic portals of the hip, specifically the anterolateral and modified anterior portals without fluoroscopic guidance. The anterolateral portal is established anatomically, and the modified anterior portal is then established under arthroscopic guidance. A through understanding of the hip anatomy allows for these portals to be made both safely and reliably for hip arthroscopies in the modified supine positioned patient...
