Rachel Shakked, Steven Sheskier
Lateral ankle instability is a common entity that can result in degenerative arthritis if left untreated. Acute ligament injuries should primarily be treated nonoperatively with a course of physical therapy and functional bracing. Chronic ankle instability is defined as mechanical or functional and can be diagnosed using a combination of history, physical examination, stress radiographs, and magnetic resonance imaging. After failure of nonoperative treatment, surgical treatment with anatomic ligament repair and inferior extensor retinaculum augmentation has the best clinical outcomes...

PURPOSE: The purpose of this study was to find a prognostic factor of medial meniscus posterior root tear (MMPRT) for surgical decision making. METHODS: Eighty-eight patients who were diagnosed as acute or subacute MMPRT without severe degeneration of the meniscus were treated conservatively for 3 months. Fifty-seven patients with MMPRT showed good response to conservative treatment (group 1), while the remaining 31 patients who failed to conservative treatment (group 2) received arthroscopic meniscus repair...

BACKGROUND: α-Melanocyte-stimulating hormone (α-MSH), an endogenous melanocortin peptide, has been demonstrated to have anti-inflammation effects and protect against cartilage damage. Objective In this study, we aimed to investigate whether α-MSH in ankle joint synovial fluid is associated with the disease severity of posttraumatic ankle osteoarthritis (PTAOA). METHODS: 66 PTAOA patients undergoing ankle arthroscopical debridement or ankle joint replacement were enrolled in the study...

PURPOSE: To investigate whether arthroscopy or stress radiography can identify instability resulting from single-ligament injury of the ankle syndesmosis and to determine whether either modality is capable of differentiating between various levels of ligament injury. METHODS: Syndesmotic/deltoid ligament sectioning was performed in 10 cadaver legs. Arthroscopic evaluation and fluoroscopic stress testing were completed after each sectioning. In group 1 (n = 5), sectioning began with anteroinferior tibiofibular ligament (AITFL), then interosseous membrane (IOM), posteroinferior tibiofibular ligament (PITFL), and deltoid...

Anterior ankle impingement is a common cause of chronic ankle pain, particularly in athletic populations. Morris and McMurray provided the earliest descriptions of anterior impingement, coining the condition as "athlete's ankle" or "footballer's ankle". The pathology has since been a topic of considerable investigation and has been re-termed "anterior ankle impingement syndrome". Treatment with open surgery has provided good results historically, but at the price of significant complications. Advancements in ankle arthroscopy have decreased the risk of complication drastically and evidence in the literature indicates that anterior arthroscopy is an effective approach to treating osseous and soft tissue impingement...

Insertional and non-insertional Achilles tendinopathy is usually treated conservatively. Surgery is indicated if conservative treatment fails to relieve the pain. Endoscopic surgery has the advantages of less morbidity, a shorter operating time, reduced postoperative pain, and a lower rate of wound and soft-tissue healing problems. Patients will have a short recovery time and quickly resume work and sports because of less soft-tissue disruption. Moreover, the pathology can be better differentiated and precisely treated...

Arthrofibrosis of the talocalcaneonavicular joint can follow trauma or surgery of the joint. Arthroscopic release of the lateral half of the talocalcaneonavicular joint is indicated if the painful restriction of hindfoot inversion together with tenderness of the lateral side of the joint that is not controlled with conservative treatment. This procedure is contraindicated in other causes of painful stiffness including post-traumatic arthritis, osteonecrosis, and malunion. This technique includes arthroscopic release of the lateral side of the anterior subtalar joint and the talonavicular joint...

Anterior ankle snapping syndrome is rare. Snapping of the extensor digitorum longus due to attenuated inferior extensor retinaculum and snapping due to hypertrophied or low-lying peroneal tertius muscle have been reported. We reported a new mechanism of anterolateral snapping due to a hypertrophied talar head. Anterolateral snapping ankle can be revealed by active dorsiflexion and plantarflexion of the ankle with the foot inverted. Foot inversion will tension the inferior extensor retinaculum and uncover the dorsolateral prominence of the talar head...

Tun Hing Lui
Adhesive capsulitis of the ankle is also known as frozen ankle and results in marked fibrosis and contracture of the ankle capsule. Arthroscopic capsular release is indicated for symptomatic frozen ankle that is resistant to conservative treatment. It is contraindicated for ankle stiffness due to degenerative joint disease, intra-articular malunion, or adhesion of the extensors of the ankle. The procedure consists of endoscopic posterior ankle capsulectomy and arthroscopic anterior ankle capsulotomy. It has the advantages of being minimally invasive surgery and allowing early postoperative vigorous mobilization of the ankle joint...

Kevin D Martin, Alicia M Unangst, Cody R Englert
Current surgical techniques in ankle fracture management now include arthroscopic-assisted reduction and internal fixation. The need for minimally invasive fracture reduction techniques, which preserve soft tissue envelops and assists in overall anatomic reduction, can be refined and improved. The ankle is an ideal anatomic location for arthroscopic-assisted reduction and internal fixation due to the high incidence of intra-articular pathology and the poor long-term sequela of nonanatomic reduction. Thus, we propose using prone posterior ankle arthroscopic reduction internal fixation for posterior ankle fracture variants...

BACKGROUND: Osteoid osteoma (OO) is a common benign bone tumour that is rarely found in the talus. Its nidus is difficult to detect on early imaging. The atypical symptoms of OO and the presence of concurrent trauma or sports injuries may lead to misdiagnosis and delayed treatment. We herein analyse a case of misdiagnosis of OO of the talus and discuss how to improve the early diagnosis of this rare lesion, thereby permitting rapid treatment. CASE PRESENTATION: A 23-year-old man with a history of left ankle sprains and chronic pain was diagnosed with another ankle sprain and managed conservatively based on normal X-ray findings...

PURPOSE OF REVIEW: Ankle sprains, which account for 40% of sports injuries in the USA, can lead to chronic ankle instability. Chronic ankle instability can be classified as functional, mechanical, or a combination of both and is diagnosed using a combination of a physical exam, an MRI, and stress radiographs. This review focuses on different approaches to treatment, including non-operative and operative techniques, of chronic ankle instability, including reviewing traditional procedures as well as more novel and newer techniques...

BACKGROUND: When performing arthroscopic ankle arthrodesis for end-stage ankle arthritis, internal fixation is performed using bone screws after appropriate preparation. However, optimal characteristics of bone screws have not been examined in terms of pressure force. Objective comparisons of bone-screw performance may provide information on procedures for arthroscopic ankle arthrodesis. The study objectives were to determine whether it was possible to measure compressive force changes using the newly developed device and to infer all screw characteristics from measurement results when used in actual surgeries...

BACKGROUND: It is unclear whether simultaneous surgery for posterior ankle impingement syndrome (PAIS) and concomitant ankle disorders, such as anterior ankle impingement syndrome (AAIS), lateral ankle instability (LAI), and osteochondral lesion of the talus (OLT), allows for early return to athletic activity. METHODS: Ninety-seven patients who engaged in athletic activity (mean age 27 [range 18-43] years) and were treated by a hindfoot endoscopic approach for PAIS alone or simultaneously for PAIS and concomitant ankle disorders were included in this study...

A 53-year-old woman underwent arthroscopic ankle debridement for posttraumatic arthrofibrosis 2 years following a bimalleolar ankle fracture. Twelve months postarthroscopy, the patient returned to physical therapy with a 2-week history of pain and prominent swelling to her anterior ankle. Urgent follow-up was arranged with an orthopaedic surgeon, who ordered a radiograph and magnetic resonance imaging, which demonstrated a large heterogeneous mass. Doppler ultrasound was also ordered and confirmed the mass to be a pseudo-aneurysm of the anterior tibial artery...
