The authors retrieved the records of 4 patients that exhibited unusual structural anomalies or pathologies, notably the presence of a fibrous band at the anterior aspect of the tibiotalar joint, observed during arthroscopic exploration or treatment between January and December 2019. Only 1 patient had surgical antecedents on the ipsilateral ankle (extra-articular tenodesis 10 years earlier). The remaining 3 patients had no surgical antecedents on the ipsilateral ankle.

Introduction: Synovial chondromatosis is a rare benign entity with the presence of cartilaginous or osseous loose bodies in the synovium. It commonly involves the larger joints such as the knee, hip, ankle and rarely the shoulder joint manifesting with pain, swelling, and restriction of movements. The treatment of choice is surgical intervention in symptomatic patients using either the open or the arthroscopic approach. Read More

Osteochondral lesions (OCLs) of the talar dome consist of a multifactorial pathology of the articular cartilage and subchondral bone and can result in persistent ankle pain and osteoarthritis (OA). Along with a physical examination and clinical history, an imaging evaluation plays a pivotal role in the diagnosis of these lesions and is fundamental for making treatment decisions and determining prognosis by providing information regarding the size, location, and cartilage and subchondral bone statuses as well as associated lesions and degenerative changes. Multiple surgical techniques for OCLs of the talar dome have been developed in recent decades, including cartilage repair, regeneration, and replacement strategies, and radiologists should be acquainted with their specific expected and abnormal postoperative imaging findings to better monitor the results and predict poor outcomes.

➤: Osteochondritis dissecans occurs most frequently in the active pediatric and young adult populations, commonly affecting the knee, elbow, or ankle, and may lead to premature osteoarthritis.

➤: While generally considered an idiopathic phenomenon, various etiopathogenetic theories are being investigated, including local ischemia, aberrant endochondral ossification of the secondary subarticular physis, repetitive microtrauma, and genetic predisposition.

➤: Diagnosis is based on the history, physical examination, radiography, and advanced imaging, with elbow ultrasonography and novel magnetic resonance imaging protocols potentially enabling early detection and in-depth staging. Read More

Background: Surgical treatment of symptomatic posterior ankle impingement consists of resection of the bony impediment and/or debridement of soft tissue. Historically, open techniques were used to perform surgery with good results. However, since the introduction of endoscopic techniques, advantages attributed to these techniques are shorter recovery time, fewer complications, and less pain. Read More

Importance: Graft choice for anterior cruciate ligament reconstruction (ACLR) remains a subject of interest among orthopaedic surgeons because no ideal graft has yet been found. Peroneus longus tendon (PLT) has emerged as an alternative autograft for reconstruction in kneeling populations and in simultaneous anterior cruciate ligament (ACL) and medial collateral ligament (MCL) injuries.

Objective: To evaluate the current evidence on the outcome of primary ACLR with PLT autograft in adults and donor ankle morbidity, in addition to determining the average PLT graft dimensions from published studies. Read More

An increased interest in ankle instability has led to description of new concepts such as ankle microinstability or rotational ankle instability and the development of new arthroscopic techniques treating ankle instability. Ankle instability is constantly associated to intraarticular pathologies that contribute to generate pain and dysfunction. Arthroscopy plays an important role in identifying and treating all intraarticular abnormalities including ligament injuries. Read More

Great toe metatarsophalangeal joint (MTPJ) arthroscopy was first described as a viable technique for a multitude of first MTPJ pathologies in the early 1970s; however, with improving arthroscopic technique and technology, these indications will continue to expand. Arthroscopy of the first MTPJ has increasingly become a new pursuit for foot and ankle specialists. Therefore, we have proposed a simple technique and illustration from our operating room setup to traction and to our procedural technique to make great toe arthroscopy simple and reproducible for arthroscopic foot and ankle surgeons.

Arthroscopic subtalar arthrodesis is a relatively new technique which is increasingly being used by foot and ankle surgeons as an alternative to open surgery. However, there is still a lack of consensus with respect to the efficacy of the procedure. The purpose of this review was to ascertain (1) whether arthroscopic subtalar arthrodesis improves the functional outcome of treated patients and (2) how do the 2 techniques of subtalar arthroscopy (posterior and lateral) compare with each other.

Introduction: Ankle arthroscopy has come a long way since it was thought, it is not feasible because of tight joint and anatomical characteristics of ankle joint. The same anatomical features like capsular attachment and safe accessory portals are used to access the whole joint even with a rigid arthroscope. Ankle distraction method was routinely used to access the anterior ankle. Read More

Background: To compare the accuracy of arthroscopic sagittal versus coronal plane distal tibiofibular motion toward diagnosing syndesmotic instability.

Methods: Arthroscopic assessment of the syndesmosis was performed on 21 above-knee cadaveric specimens, first with all ligaments intact and subsequently with sequential transection of the anterior inferior tibiofibular ligament, the interosseous ligament, the posterior inferior tibiofibular ligament, and the deltoid ligament. A lateral hook test, an anterior-to-posterior (AP) translation test, and a posterior-to-anterior (PA) translation test were performed under 100 N of applied force. Read More

Foot and Ankle Research and Innovation Laboratory, Massachusetts General Hospital, Harvard Medical School, Boston, MA, USA; Foot and Ankle Service, Department of Orthopaedic Surgery, Massachusetts General Hospital and Newton-Wellesley Hospital, Harvard Medical School, Boston, MA, USA.

Background: Although ankle arthroscopy is increasingly used to diagnose syndesmotic instability, precisely where in the incisura one should measure potential changes in tibiofibular space or how much tibiofibular space is indicative of instability, however, remains unclear. The purpose of this study was to determine where within the incisura one should assess coronal plane syndesmotic instability and what degree of tibiofibular space correlates with instability in purely ligamentous syndesmotic injuries under condition of lateral hook stress test (LHT) assessment.

Methods: Ankle arthroscopy was performed on 22 cadaveric specimens, first with intact ankle ligaments and then after sequential sectioning of the syndesmotic and deltoid ligaments. Read More

Department of Orthopaedic Surgery, Henry Ford Health System, West Bloomfield, Michigan, U.S.A.. Electronic address:

Purpose: The purpose of the current study was to (1) determine the percentage of new orthopedic patients reporting their symptoms to be acceptable at presentation, as measured by the Patient Acceptable Symptom State (PASS) question, and (2) evaluate whether patient-reported outcome measures (PROMs), including Patient-Reported Outcome Measurement Information System (PROMIS) Physical Function (PF) or Upper Extremity, Pain Interference (PI), and Depression (D), or sociodemographic factors are associated with acceptable symptoms at presentation.

Methods: Between February 7, 2020, and March 16, 2020, new orthopedic patients who completed PROMs were identified. Patient records were reviewed for those who also completed the PASS question, a yes/no question about whether a patient's current symptom state is satisfactory. Read More

Noninvasive ankle distraction technique is the standard of care for ankle arthroscopic surgery. Noninvasive distraction can be performed safely and with fewer complications when compared side-by-side with the nondistraction dorsiflexion technique. Moreover, distraction techniques allow a single surgeon to operate in the most convenient supine position and in a "hands-free" manner, with adequate space to avoid iatrogenic chondral damage.
