Medial Patellofemoral Ligament and Lateral Patellofemoral Ligament Reconstruction after Tibial Tuberosity Transposition in a Young Woman with Patellar Instability

In patients with reccurent lateral and medial patellar instability, isolated medial patellofemoral ligament (MPFL) reconstruction may be insufficient due to poor lateral retinacular tissue quality. In this report, we describe a case of a patient that underwent simultaneous MPFL and lateral patellofemoral ligament (LPFL) reconstruction on the left knee due to chronic bidirectional patellar instability. A 29-year-old female patient presented with first-time lateral patellar dislocation five years ago due to acute strain. She underwent a tibial tuberosity transposition in another hospital. After the surgery, she suffered from recurrent medial and lateral patellar dislocation and presented to our center. MPFL and concomitant LPFL reconstruction on the left knee was simultaneously performed due to bilateral patellar dislocation. The patella was stable postoperatively, and the patient underwent physiotherapy with successful results to date. Single-time patellar dislocation should be treated conservatively. Surgical treatment after the first episode of dislocation can magnitude the risk of postoperative complications. The simultaneous reconstructing of the LPFL yields patellar fixation indistinguishable from the native LPFL. These grafts provide separate tensioning depending on body anatomy, allowing for individualized stability. Anatomical MPFL reconstruction is supported by well-established high-quality research. Reconstructing the LPFL anatomically yields patellar fixation indistinguishable from the native LPFL.

Acute clinical evaluation for the diagnosis of lateral ankle ligament injuries is useful: A comparison between the acute and delayed settings.

To determine the diagnostic value of seven injury history variables, nine clinical tests (including the combination thereof) and overall clinical suspicion for complete discontinuity of the lateral ankle ligaments in the acute (0-2 days post-injury) and delayed setting (5-8 days post-injury). All acute ankle injuries in adult athletes (≥18 years) presenting up to 2 days post-injury were assessed for eligibility. Athletes were excluded if imaging studies demonstrated a frank fracture or 3 T MRI could not be acquired within 10 days post-injury. Using standardized history variables and clinical tests, acute clinical evaluation was performed within 2 days post-injury. Delayed clinical evaluation was performed 5-8 days post-injury. Overall, clinical suspicion was recorded after clinical evaluation. MRI was used as the reference standard. Between February 2018 and February 2020, a total of 117 acute ankle injuries were screened for eligibility, of which 43 were included in this study. Complete discontinuity of lateral ankle ligaments was observed in 23 (53%) acute ankle injuries. In the acute setting, lateral swelling had 100% (95% confidence interval [CI]: 82-100) sensitivity, haematoma had 85% (95% CI: 61-96) specificity and the anterior drawer test had 100% (95% CI: 77-100) specificity. In the delayed setting, sensitivity for the presence of haematoma improved from 43% (95% CI: 24-65) to 91% (95% CI: 70-98; p < 0.01) and the sensitivity of the anterior drawer test improved from 21% (95% CI: 7-46) to 61% (95% CI: 39-80; p = 0.02). Clinical suspicion had a positive likelihood ratio (LR) of 4.35 (95% CI: 0.55-34.17) in the acute setting and a positive LR of 6.09 (95% CI: 1.57-23.60) in the delayed setting. In the acute setting, clinical evaluation can exclude complete discontinuity (e.g., absent lateral swelling) and identify athletes with a high probability of complete discontinuity (e.g., positive anterior drawer test) of the lateral ankle ligaments. In the delayed setting, the sensitivity of common clinical findings increases resulting in an improved diagnostic accuracy. In clinical practice, this study underlines the importance of meticulous clinical evaluation in the acute setting. Level III.

Impact resisting mechanism of tension–torsion coupling metamaterials

Tension–torsion coupling (TTC) metamaterials are man-made architectures that exhibit unexpected rotational deformation when subjected to unidirectional loads. Since their discovery, numerous studies have been conducted to investigate the static properties of TTC metamaterials resulting from this twisting effect. However, research on their dynamic properties, particularly in terms of impact resistance, has been limited with little understanding of the underlying mechanisms. In this study, we performed simulations at different length scales to quantitatively analyze the energy flow during impact and gained insights into the mechanisms of energy damping and impact resistance. Our simulations demonstrate that the twisting effect of cellular materials generally leads to reduced stiffness, which is advantageous for improving impact mitigation. Furthermore, we discovered that the unique chiral characteristics of TTC metamaterials enable a greater amount of strain energy to be stored during impact, and this portion of energy will be ultimately dissipated through after-impact vibrations. Additionally, we found that energy dissipation via friction between lateral struts or ligaments, although less significant, is enhanced by the TTC effect. The current study provides a preliminary analysis of energy flow and sheds light on the mechanisms underlying the energy damping and impact resistance of TTC metamaterials. These findings not only contribute to a better understanding of the dynamic properties of TTC metamaterials but also have practical implications for the advanced design of impact resistance structures.

Anatomical analysis of ligaments surrounding calcaneocuboid joint; implications for role in foot stability.

The calcaneocuboid joint is located in the lateral part of the foot and acts as a major stabilizer for the foot. Injuries to this joint often occur in association with ankle or foot injuries and are frequently overlooked, subsequently causing chronic pain or osteoarthritis. However, the relationship between ligaments surrounding the joint and joint instability remains unclear. Therefore, this study aimed to clarify the morphology and position of the ligaments surrounding the calcaneocuboid joint, and to reveal the relationship between the ligament structure. The position and morphology of the bifurcate ligament (subdivided into calcaneonavicular and calcaneocuboid ligaments), dorsal calcaneocuboid ligament, lateral calcaneocuboid ligament, long plantar ligament, and short plantar ligament were measured (N = 11 feet in 6 Japanese cadavers). The circumference of the joint was quartered, while the ligament-uncovered area and the estimated cross-sectional area of each ligament were compared between the four sides. Furthermore, the estimated cross-sectional area of each ligament was calculated as an index for the ligament strength. The inferolateral side of the calcaneocuboid joint had the most uncovered area (54.63%) by the ligaments. In addition, the cross-sectional area of the ligaments on the lateral side was considerably smaller than that on the medial side. Our results suggest that ligament weakness on the inferolateral side may cause instability of the calcaneocuboid joint, especially after an inversion sprain injury, and may decrease the lateral longitudinal arch function, which results in chronic foot pain.

Arthroscopic Modified Lasso-Loop Stitch Technique for Chronic Lateral Ankle Instability in Skeletally Immature vs Mature Patients.

In recent years, arthroscopic lateral ankle ligament repair has become increasingly popular. However, reports on the clinical outcomes of arthroscopic ankle stabilization for skeletally immature patients remain scarce. This study investigated the clinical outcomes of arthroscopic lateral ankle ligaments repair in skeletally immature patients compared to skeletally mature patients. Our retrospective analysis compared skeletally immature patients and skeletally mature adults who underwent arthroscopic repair of the ankle lateral ligaments with a modified lasso-loop stitch using a suture anchor. Skeletal immaturity was defined as patients whose epiphyseal line of the distal fibula remained open on plain radiography. Clinical outcomes were evaluated using the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) at 2 years after surgery. The time to postoperative walking, jogging, and return to full sports activities were also evaluated. Sixty-four skeletally immature patients (IM group) and 103 skeletally mature adults (M group) were included. No significant differences were observed during both walking and jogging after surgery between the groups; however, return to full athletic activities was significantly earlier in IM group (P = .05). The mean scores in all SAFE-Q subscales significantly improved in both groups after surgery (P < .001). There were also no statistically significant differences between the groups in the mean postoperative SAFE-Q scores for all subscales. All patients in the IM group returned to playing sports at their preinjury levels postoperatively. We found that skeletally immature patients with chronic lateral ankle instability had generally similar responses to arthroscopic lateral ankle as skeletally mature adult patients at minimally 2 years' follow-up with a high rate of successful return to sport. Level III, retrospective case control study.

MRI Assessment of Tendon Graft After Lateral Ankle Ligament Reconstruction: Does Ligamentization Exist?

Background: No description exists in the literature about the normal evolution of tendon graft after a lateral ankle ligament (LAL) reconstruction. Purpose: To assess the magnetic resonance imaging (MRI) characteristics and the evolution of the tendon graft during different moments in the follow-up after an endoscopic reconstruction of the LAL. Study Design: Cohort study; Level of evidence, 3. Methods: This prospective study included 37 consecutive patients who underwent an endoscopic reconstruction of the LAL with an autograft using the gracilis tendon to treat chronic ankle instability (CAI) resistant to nonoperative treatment (CAI group) and 16 patients without ankle instability (control group). All patients in the CAI group underwent a postoperative assessment at 6, 12, and 24 months using the Karlsson score and MRI examination. Only patients with good and excellent results were included in the study. Graft assessment consisted of qualitative measurements and quantitative evaluations of the reconstructed anterior talofibular ligament (RATFL) and reconstructed calcaneofibular ligament (RCFL), including signal-to-noise quotient (SNQ) and contrast-to-noise quotient (CNQ) measurements in proton density–fat suppressed (PD-FS) and T1-weighted sequences. The analysis of variance test was used to compare the SNQ and the CNQ at different time points for each sequence. Results: The MRI signal at 6 months was increased compared with that of the control group. Next, a significant signal decrease from 6 to 24 months was noted on PD-FS and T1-weighted images. SNQ measurements on PD-FS weighted images for both the RATFL and the RCFL demonstrated a significantly higher signal (P < .01 and P = .01, respectively) at 6 months compared with that of the control group. Subsequently, the signal decreased from 6 to 24 months. Similarly, CNQ measurements on PD-FS weighted images for both the RATFL and the RCFL demonstrated a significantly higher signal (P < .01 and P < .01, respectively) at 6 months compared with that of the control group. Subsequently, the signal decreased from 6 to 24 months. Conclusion: The present study demonstrated an evolution of the MRI characteristics, suggesting a process of graft maturation toward ligamentization. This is important for clinical practice, as it suggests an evolution in graft properties and supports the possibility of creating a viable ligament.

Evaluation of Canine Shoulder Arthroscopy for Anatomical and Safety Considerations.

Arthroscopy is a well-established diagnostic modality for various orthopaedic conditions in veterinary medicine. The aim of this study was to describe the relationship of canine shoulder arthroscopy portals to major muscular, ligamentous, and neurovascular structures for anatomical and safety considerations. Arthroscopic exploration of 20 adult canine cadaver shoulders was performed. Each shoulder region was dissected layer by layer to the level of the joint. Musculotendinous, ligamentous, and cartilaginous lesions were documented. The distance was measured from each portal to neurovascular structures encountered. Muscular lesions included the deltoideus, cleidobrachialis, omotransversarius, supraspinatus, infraspinatus, and teres minor muscles. The neurovascular structures identified were the omobrachial vein, the caudal circumflex humeral artery, axillobrachial vein, and branches of the axillary nerve. Lesions to the lateral glenohumeral ligament were noted from the caudal instrument portal and the middle arthroscope portal. Iatrogenic articular cartilage injuries were identified on the caudal humeral head and the glenoid. This study supports the safety of lateral shoulder arthroscopy in dogs. Most local neurovascular structures are unaffected with traditional scope portal positions. Musculotendinous lesions are unavoidable due to the extensive muscling surrounding the shoulder but are unlikely to cause severe complications postoperatively.

Lateral Ankle Ligaments: An Insight Into Their Functional Anatomy, Variations, and Surgical Importance.

Ankle sprains are prevalent injuries leading to functional impairment. The lateral ankle ligament complex (LLC), comprising the anterior talofibular ligament (ATFL), posterior talofibular ligament (PTFL), and calcaneofibular ligament (CFL), is weak and prone to injury. The morphometric data of these ligaments are essential for orthopedic practices, including techniques like direct repair or ATFL reconstruction with autograft/allograft, which are limited in the literature. The present study aims to document the anatomy and morphometry of the LLC. Fifteen adult Indian-origin embalmed cadavers were selected for the study. Ankles with antemortem or postmortem injuries or previous surgical interventions were excluded from the study. After precise dissection of the ankle's anterior and lateral aspects as per Cunningham's dissection manual, ligaments were exposed. Length and width were measured using a digital vernier caliper. Morphological attributes such as shape, orientation, and inter-fiber angles were documented. The most common shape in ATFL was a single band (53.33%). Inner ATFL fibers merged with the ankle joint capsule in 73.33%. ATFL mean length and width were 14 ± 2.4 mm and 7.6 ± 2.0 mm. The angle between the fibula's long axis and ATFL fibers was 107 ± 22°, and the angle between tibiotalar joint lines and parallel ATFL fibers was 30 ± 9.5°. A single band of CFL was predominant (73.33%). The mean length and width ofCFL were 18.4 ± 3.9 mm and 5.2 ± 1.3 mm; the angle between the anterior fibula border's long axes and parallel CFL line was 131°. PTFL length was 20.9 ± 3.3 mm and width was 6.2 ± 1.4 mm. The mean length and width of the anterior inferior talofibular ligament (AiTFL) were 11.7 ± 2.6 mm and 9.5 ± 1.6 mm, and of the posterior inferior talofibular ligament (PiTFL) were 12.8 ± 2.1 mm and 10.4 ± 2 mm. Comprehensive knowledge of these ligaments' anatomy and relationships is vital for clinical examination and ultrasonography. Understanding LLCdetails aids radiologists and orthopedic surgeons in graft selection, sizing, and precise anatomical structure placement during surgical reconstruction.

Injuries of the ankle ligaments

Lateral ligament injuries are the most common injuries of the ankle joint and are usually treated with early weight bearing after a short period of immobilization. If the clinical presentation is suspicious, additional injuries to the deltoid ligament complex and the syndesmosis should be considered. The indications for additional diagnostics should be generously applied. Injuries to the deltoid ligament usually occur as part of acomplex ankle injury and should also be addressed in the surgical treatment of accompanying injuries. Chronic instability in this area necessitates complex bony and soft tissue procedures. Syndesmotic injuries with insufficiency of the capsule-ligament apparatus are frequent in ankle fractures and are stabilized during fracture treatment. Isolated syndesmotic instability should also be surgically treated as chronic injuries are usually associated with poor clinical results and early osteoarthritis.

Enhancing the Diagnosis of Lateral Ankle Sprains: The Role of MSK Diagnostic Ultrasound in Evaluating ATFL and CFL.

Lateral ankle sprains, predominantly involving the anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL), constitute a significant portion of sports-related injuries, with a notable rate of recurrence and progression to chronic instability. Precise diagnosis and effective treatment of the ATFL and CFL injuries are crucial in preventing long-term complications. Musculoskeletal (MSK) diagnostic ultrasound has emerged as a pivotal tool in the rehabilitation sector, particularly in assessing lateral ankle ligament injuries. This article will highlight its benefits over traditional diagnostic methods and the emerging role of MSK diagnostic ultrasound as a superior tool for accurate, cost-effective, and comprehensive assessment of these injuries. We discuss the technology's ability to provide objective, real-time imagery, facilitating accurate diagnosis, treatment planning, and injury monitoring emphasizing the need for a standardized approach to ultrasound evaluation to improve diagnostic accuracy and patient outcomes.

Surgical Technique for Lateral Patellofemoral Ligament Reconstruction Using Bone Tunnels: A New Method.

Medial patellar instability (lateral patellofemoral ligament tear) is a rare condition which is commonly associated with lateral release for lateral patellar instability. LPFL is a lateralstabilizer of the patellofemoral joint. Reconstruction of LPFL is necessary to provide stability to the patella-femoral joint in patients with instability. We describe a novel technique of trans-osseous reconstruction of LPFL to gain stability and have better graft incorporation. A doubled peroneus longus graft is inserted into the patellar tunnel and secured with an endo button on the anteromedial aspect of the patella; the other end is then inserted into the insertional point on the femur and secured with an interference screw. This is an easy, novel, and reproducible technique which can be used to reconstruct LPFL.

Comparative analyses of arthroscopic and open repairs of lateral ligament complex injuries of the ankle: a systematic review and meta-analysis of the medium-term outcomes.

Little is known regarding the comparative analyses of the medium-term outcomes (with a mean minimum follow-up period of 24months), between arthroscopic and open repairs of lateral ligament complex (LLC) injuries of the ankle. Thus, in this study, we aimed to explore the comparative analyses regarding the medium-term follow-up outcomes of these repairs, by conducting a systematic review and meta-analysis. The systematic review and meta-analysis were performed as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines; data were extracted from the PubMed and Google Scholar databases. From an initial search, a total of 1182 abstracts (280 and 902 abstracts, from PubMed and Google Scholar, respectively) were found and screened in accordance with the eligibility criteria. Subsequently, six articles were found to be eligible for further review. A total of 419 patients underwent surgical repairs; 205 and 214 patients underwent arthroscopic and open repairs, respectively. The mean minimum follow-up period was 29.2months. The medium-term follow-up for arthroscopic LLC repairs was found to be superior to that of open LLC repairs, with more favorable outcomes; as evidenced by better clinical scores, lower pooled complication rates, earlier return times to pre-injury sport, and higher early sport ratios. The findings of this systematic review and meta-analysis support near-future developments validating arthroscopic repair as the new gold standard for LLC repairs, similarly to arthroscopic ligament and tendon repairs, as well as arthroscopic reconstruction surgeries, of the knee and shoulder.

Efficacy of Proprioceptive Training and Conventional Training in Reducing Pain and Improving Functional Activity for people with Lateral Ligament Injury

Description of the lateral fibulotalocalcaneal ligament in fetal specimens and its potential clinical implications.

The increase in ankle sprains in children is a reflection of the greater inclusion of this population in sports. This places the calcaneofibular (CFL) and the anterior talofibular (ATFL) ligaments in focus for study. In adults, the presence of arcuate fibers extending between these two ligaments suggests the existence of a new anatomical and functional complex called the lateral fibulotalocalcaneal ligament of the ankle (LFTCL), which can be associated with the persistence of instability of the talocrural joint in ankle sprains. This study aimed to verify the presence of arciform fibers between the CFL and ATFL in human fetuses and to study the topography of the lateral ankle region. Forty matched fetal ankles aged between 28 and 38weeks, fixed in 4% formalin, were macroscopically, chemically and mesoscopically dissected and analyzed in stereoscope. The ATFL was characterized as a capsular ligament consisting of two fascicles (proximal and distal). The CFL was characterized as an extracapsular ligament. The LFTCL complex was verified in all specimens, characterized by the arcuate fibers between the ATFL and the CFL. Such results suggest that this functional unit is congenital and that it should be taken into consideration in the treatment of persistent ankle instabilities in the pediatric population.

A Review of Chronic Lateral Ankle Instability and Emerging Alternative Outcome Monitoring Tools in Patients following Ankle Ligament Reconstruction Surgery.

Ankle sprains are exceedingly common injuries in both athletes and the general population. They account for 10 to 30% of all sports injuries. Although the vast majority of lateral ankle ligament injuries respond successfully to conservative management, the absolute number of those that progress to chronic lateral ankle instability (CLAI) remains considerably important. This condition is characterized by persistent symptoms and may be associated with short-term and long-term complications and functional deficits. There is still a lack of ideal postoperative management of CLAI patients. Furthermore, an evidence-based rehabilitation phasing does not exist and most of the published studies regarding this subject suggest some protocols based on a wide variety of functional assessment scores and other modalities that are not accurate enough. Moreover, the literature that assesses the ability to return to work (RTW) and return to sport (RTS) in the general population and athletes operated for CLAI most commonly shows aggregated results with global rates of RTW or RTS without describing a detailed timeline based on the readiness of patients to return to each level of activity. Although stress radiographs and MRI have been assessed as potential tools to improve postoperative management of CLAI patients, the first modality is limited by its low sensitivity to detect laxity and the second one by its static character and its inability to predict neither the healing process phase nor the mechanical properties of the repaired/reconstructed ligaments. Bioelectrical impedance, mechanical impedance and near-infrared spectroscopy are non-invasive methods of measurement that could be potential assessment tools to help surgeons improve the postoperative management of patients after CLAI surgery.

Is Lateral Ligament Complex Repair Necessary in All Unstable Elbow Injuries with Coronoid Fractures? A Comparative Study: A Case Series

Is Lateral Ligament Complex Repair Necessary in All Unstable Elbow Injuries with Coronoid Fractures? A Comparative Study: A Case Series

Treatment of chronic instability of the ankle joint caused by lateral ligament complex trauma: review

Background. The incidence of injuries to the lateral ligaments of the ankle joint is up to 22% of all sports injuries and 85% of all ankle sprains. Most of these are effectively managed using nonoperative measures in the acute setting. Approximately 20% of patients will, however, develop chronic lateral ankle instability. A key point to surgical treatment of chronic lateral ankle instability is choosing a suitable surgical procedure. The aim is to evaluate treatment options for chronic ankle instability and determine the state of the problem of current methods of treatment. Material and methods. For the analysis of the literature, 100 foreign articles were selected on chronic instability of the ankle joint and methods of its treatment, published from 1985 to 2023, as well as 18 domestic publications for the period from 2007 to 2022. 59 most relevant articles were selected. Publications were searched in the PubMed/MedLine and eLIBRARY databases. Results. Recent and remote literature agrees that the initial treatment for chronic lateral ankle instability is non-operative rehabilitation. In the cases where this fails, the gold standard of surgical treatment is open anatomic repair using the Brostrom-Gould technique which stands out as having very good results over the course of time. Recent studies have shown equally good outcomes with arthroscopy and both techniques show potential for earlier rehabilitation. In those with contraindications for anatomic repair including innate soft tissue laxity, high body mass index, and in the revision setting, anatomic ligament reconstruction is an appropriate surgical option. Conclusion. There is limited evidence to support any particular surgical technique over another surgical technique for chronic lateral ankle instability. The open modified Brostrom-Gould collateral ligament repair continues to be the preferred method of surgical treatment for chronic lateral ankle instability. Nonanatomic reconstruction abnormally increases inver-sion stiffness at the subtalar level compared with anatomic reconstruction and shows greater clinical dissatisfaction. Arthroscopic repair can reduce recovery time and improve outcomes in certain populations, but there is a higher complication rate with these surgeries. When using new modifications and techniques, long-term outcome studi-es are needed to determine their long-term usefulness and compare them with the results of open surgery

Patient-Reported Outcomes Following Open Broström-Gould Procedure: Minimum 5-Year Follow-Up.

Ankle sprains are a common musculoskeletal injury among the general population and often involve the lateral ligament complex. Although the majority of ankle sprains are treated successfully with nonsurgical conservative measures, an estimated 5% to 20% of ankle injuries ultimately develop chronic lateral ankle instability (CAI). Multiple surgical treatment modalities for the lateral ankle complex exist, such as anatomical and nonanatomical reconstruction. The current gold standard for primary surgical repair is the Broström-Gould procedure. This is the first article to provide PROMIS scores following BG and the largest study with 5-year outcomes for an open BG. This was a descriptive study of a retrospective cohort of patients undergoing a BG with a minimum follow-up of 5 years. Patient-reported outcome instruments collected postoperatively were PROMIS Pain, Physical Function, Depression, and FAAM. Further preoperative clinic characteristics were analyzed to correlate with the final outcome. The electronic medical record was queried for Current Procedural Terminology (CPT) code 27698 (Broström-Gould) from January 2010 to June 2017. Surveys were conducted in the clinic and through phone interviews. Patient charts were reviewed to obtain basic patient demographic information including sex, age, race, and body mass index (BMI). The following preoperative variables were recorded: history of prior CAI procedures, history of major trauma, duration of symptoms, number of diagnosed ankle sprains, other collagen pathologies, generalized ligament laxity, participation in sports/activity level, peroneal subluxation, clinically diagnosed peroneus longus or brevis tendinopathy, deltoid ligament injury, anterior ankle impingement, and posterior ankle impingement. The PROMIS and Foot and Ankle Ability Measure (FAAM) scores were obtained with a combination of clinic and phone interviews. Data were aggregated in Microsoft Excel and entered in R (version 4.2.0) for statistical analysis. Our results show that the minimum 5-year patient-reported PROMIS scores for patients following a Broström-Gould procedure are as follows: PROMIS physical function, 50.5; PROMIS pain interference, 48.2; and PROMIS depression, 38.2. This indicates, at a minimum, that patients 5 years removed from the procedure are within 1 SD of the general population in regard to PROMIS physical function and pain. Our patient-reported FAAM, activities of daily living, and FAAM sports scores were 59.6 and 13.0 respectively. Preoperative magnetic resonance imaging (MRI) findings were recorded. Arthroscopic examination was performed before lateral ligaments reconstruction for patients with intra-articular pathologies confirmed on MRI. The findings from our study offer evidence supporting the effectiveness of the Broström-Gould procedure to be associated with normal physical function, even 5 years after surgery. Furthermore, our research identified specific factors such as tobacco use, diabetes, and sports participation that independently correlated with reported outcome measures. These insights enable physicians to better manage patient expectations and tailor treatment strategies accordingly. Our study establishes a foundation for future prospective research endeavors that aim to leverage the PROMIS system for comprehensive outcome assessments. Level III, retrospective cohort study.

A Re-look at chrisman-snook: A narrative review and technique guide for lateral ankle ligament reconstruction with tendon allograft

Chronic ankle instability is a pathology arising from one of the most common orthopedic injuries, lateral ankle sprains. The gold standard surgical procedure for lateral ankle instability is repair of the anterior talofibular and calcaneofibular ligaments with imbrication of the inferior extensor retinaculum. The senior author's indications for a modified Brostrom versus a modified Chrisman-Snook have evolved over the past decade. Indications for a modified Chrisman-Snook include: revision reconstruction, generalized laxity, collagen vascular disease, BMI greater than 35, and significant hindfoot varus or midfoot cavus. The primary aim of this report is to provide a narrative review of the Chrisman-Snook procedure and overview of our modified technique.
