Anterior Ankle impingement

Objective: To explore whether the combination of anterior bony impingement before surgery will affect the efficacy of the lateral collateral ankle ligament reconstruction surgery in patients with chronic ankle instability (CAI). Methods: A prospective cohort study. Patients with CAI who underwent lateral collateral ankle ligament reconstruction from January 2014 to October 2017 in the Department of Sports Medicine, Huashan Hospital, Fudan University were enrolled in this study. The patients were divided into no bony impingement group (NI group) and bony impingement group (BI group) according to the presence of bone impingement in front of the ankle during the operation...

PURPOSE: The aim of this study was to evaluate the relation between anteromedial ankle osteophytes (AMAO) and anteromedial ankle impingement (AMAI) in chronic lateral ankle instability (CLAI) through visualization and quantification. METHODS: Forty-three patients with unilateral CLAI between September 2018 and March 2020 accepted arthroscopic repair of an anterior talofibular ligament (ATFL) and were split into two groups: AMAI (AMAI including intraoperative AMAO resection) and pure CLAI (with AMAO but without AMAI, no AMAO resection)...

OBJECTIVE: Ankle arthroscope is the preferred tool for ankle surgeons to treat ankle impingement. However, there is no relevant report on how to improve the accuracy of arthroscopic osteotomy through preoperative planning. The aims of this study were to investigate a novel method to obtain the bone morphology in anterior and posterior ankle bony impingement through computed tomography (CT) calculation model, use this method to guide surgical decision-making, and compare the postoperative efficacy and actual bone cutting volume with conventional surgery...

PURPOSE: This study aimed to introduce a novel all-inside arthroscopic anterior talofibular ligament (ATFL) repair for chronic ankle instability (CAI) with a knotless suture anchor technique-Hugging Repair, evaluate clinical outcomes, and analyze the associated risk factors. METHODS: A total of 84 patients (42 males and 42 females, mean age: 36.1 ± 11.2 years, range: 19-68 years) who underwent Hugging Repair from January 1, 2016 to December 31, 2018, were enrolled in this retrospective study...

Anterior ankle impingement syndrome can frequently present in athletes and post-traumatic patients who have osteophytes contributing to limited dorsiflexion and pain. Surgical treatment options include arthroscopy, open arthrotomy, arthrodesis, and total implant arthroplasty. For many, joint-sparing arthroscopy or arthrotomy yield satisfactory results if significant debridement is performed. If debridement is not aggressive, patients may not obtain the desired improvement. In cases where a larger amount of bone must be removed, or the patient does not have an anatomic appearing talar neck due to osteophytic changes, we have found that an open approach is necessary to achieve good results...

PURPOSE: To summarize the incidence of injuries occurring in professional baseball and compare player outcomes reported in the literature. METHODS: We conducted a systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines across 3 databases (PubMed, MEDLINE, Embase). Inclusion criteria were studies of injury incidences and/or injury outcomes on active Major League Baseball (MLB) athletes and studies published in the English language...

Dancers are highly vulnerable to injuries due to high dynamic overload, extreme positions and motions, and excessive use. Increased load at the forefoot with jumping and high-impact lands can cause sesamoiditis and stress fractures of the metatarsals. Significant plantarflexion can lead to posterior joint impingement and flexor hallucis longus tendonitis, whereas forced dorsiflexion can cause anterior joint impingement. Most pathologies can be diagnosed on physical examination and various imaging modalities...

BACKGROUND: Chronic lateral ankle instability is treated operatively, whereas most acute ankle sprains associated with acute anterior talofibular ligament injury are usually treated nonoperatively. This treatment strategy is widely accepted and has been validated using a variety of clinical or radiological methods. We suspected that there may be biological differences between chronic and acutely injured ligaments, particularly with respect to apoptosis. Apoptosis is known to cause ligament degeneration...

PURPOSE: To study the epidemiology and return to play characteristics of anterior and posterior ankle impingement syndromes (AAIS and PAIS) over 18 consecutive seasons in male professional soccer players. METHODS: Between the 2001-2002 and 2018-2019 seasons, 120 European soccer teams were followed prospectively for various seasons. Time loss injuries and player exposures were recorded individually in 6754 unique players. Injury incidence and burden were reported as the number of injuries and days absence per 1000 h with 95% confidence intervals (CIs)...

The fibulocalcaneus (peroneocalcaneus) internus (PCI) muscle is a rare variant leg muscle with a low prevalence of <1%-3% in cadaveric dissection and imaging studies. The PCI arises from the medial aspect of the distal third of the fibula, descends posterior and lateral to the flexor hallucis longus (FHL) muscle, traverses the tarsal tunnel inferior to the sustentaculum tali of the calcaneus, and inserts into the plantar surface of the calcaneus. However, controversy exists concerning the exact location of the insertion site of the PCI muscle...

Purpose: The purpose of the study was to investigate the added value of electrothermal denervation (ETD) in arthroscopic debridement of anterior ankle impingement. Methods: Between May 2019 and December 2020, 58 patients who received arthroscopic anterior decompression for the impingement of the anterior tibiotalar joint were randomized to Group A ( n  = 29) with ETD of synovial and capsular tissue of the ankle and Group B ( n  = 29) without ETD. Patients included 37 men and 21 women, with a mean age of 42 years...

Background: We often attribute the lateral ankle impingement to the valgus calcaneus, while ignoring the varus distal tibia. The diagnostic criteria, severity and treatment of distal tibia varus syndrome (DTVS) have not been reported. This retrospective study sought to propose a diagnosis and classification system for DTVS based on patients' clinical symptoms and imaging findings. Methods: A total of 76 symptomatic patients with varus distal tibia and congruent ankle examined between 2010 and 2018 were involved to evaluate clinically based on their SF-36 scores, AOFAS ankle-hindfoot scores, and VAS scores...

OBJECTIVE: To investigate the surgical skills and clinical curative results of arthroscopic treatment of ankle instability combined with anteromedial impingement syndrome. METHODS: From February 2019 to August 2020, 13 patients with ankle instability combined with anteromedial impingement were retrospectively analyzed. There were 10 males and 3 females with age of (40.0±15.1) years old. The course of disease was(44.1±33.2) months. All patients had history of ankle sprain...

We report a case of equinus foot deformity and malunion of the medial malleolus caused due to tibialis posterior tendon interposition following irreducible fracture-dislocation of the ankle. A 19-year-old female patient was referred to our hospital with the chief complaint of persistent ankle pain and restricted ankle dorsiflexion. Her medical history revealed a fracture-dislocation of the ankle in the left tibia at the age of 18 years. Open reduction and osteosynthesis were performed 3 days after injury...

BACKGROUND: Insertional Achilles tendinopathy (IAT) is characterized by tendon degeneration and thickening near the tendon-bone insertion.11 Calcaneal impingement is believed to contribute to the pathogenesis of IAT.5 However, it is unclear how increased tendon thickness in individuals with IAT influences impingement. This study aimed to compare Achilles tendon impingement in individuals with and without IAT. METHODS: Eight healthy adults and 12 adults with clinically diagnosed symptomatic IAT performed a passive flexion exercise during which ankle flexion angle, anterior-posterior (A-P) thickness, and an ultrasonographic image sequence of the Achilles tendon insertion were acquired...

The transfibular approach is a widely used method in ankle arthrodesis. However, it is difficult to correct coronal plane deformity. Moreover, it carries a risk of nonunion and requires long periods of non-weight-bearing because of its relatively weak stability. We hypothesized that the transfibular approach combined with the anterior approach in ankle arthrodesis wound yield a higher fusion rate and shorter non-weight-bearing period. This study was performed to evaluate the clinical and radiographic results and postoperative complications in ankle arthrodesis using combined transfibular and anterior approaches in end-stage ankle arthritis...

BACKGROUND: Arthroscopic debridement is a common surgical treatment for patients with anterolateral impingement (ALI) of the ankle. Although they often have a history of ankle sprain, information regarding the role of ankle instability in ALI is limited. The aims of this review were to 1) assess the clinical outcomes of arthroscopic surgical treatment for ALI of the ankle and 2) review the data regarding anterior talofibular ligament (ATFL) injury and lateral ankle instability in patients who underwent arthroscopic surgery for ALI...

Ankle sprains are a common cause of morbidity in the general and athletic population. The majority of sprains involve the lateral aspect of the ankle, affecting the anterior talofibular ligament. However, the extent and categories of injury will depend upon the mechanism of injury. The ankle injury caused by ankle sprain is not only the injury of lateral collateral ligaments, but also chondral or osteochondral lesions of the talus, anterior ankle impingement, posterior ankle impingement and so on. In addition to the involvement of ankle joint, ankle sprain often leads to the injury of subtalar joint and transverse tarsal joint, even stress fracture, special part fracture or tendon soft tissue injury; multiple injuries often coexist...
