OBJECTIVE
This paper presents an exploratory case study focusing on the applicability and value of process mining in a professional sports healthcare setting. We explore whether process mining can be retrospectively applied to readily available data at a professional sports club (Football Club Barcelona) and whether it can be used to obtain insights related to care flows.
DESIGN
Our study used discovery process mining to detect patterns and trends in athletes' Post-Pre-Participation Medical Evaluation injury route, encompassing five phases for analysis and interpretation.
RESULTS
We examined preprocessed data in event log format to determine the injury status of athletes in respective baseline groups (healthy or pathological). Our analysis found a link between thigh muscle injuries and later ankle joint problems. The process model found three loops with recurring injuries, the most common of which were thigh muscle injuries. There were no differences in injury rates or the median number of days to return to play between the healthy and pathological groups.
CONCLUSIONS
This study explored the applicability and value of process mining in a professional sports healthcare setting. We established that process mining can be retrospectively applied to readily available data at a professional sports club and that this approach can be used to obtain insights related to sports healthcare flows.

Checkrein deformity is rare and involves entrapment or fixed tethering of the flexor hallucis longus (FHL) in the posterior foot, just proximal to the flexor retinaculum of the ankle, and causes the "constant length phenomenon" of FHL. The clinical presentation is a dynamic flexion deformity of the great toe characterized by flexion contracture of the interphalangeal joint with mild extension contracture of the metatarsophalangeal joint, causing difficulty in walking since in the stance phase of gait, the hallux is forced into plantar flexion and impinges onto the ground. Because the FHL tendon has some interconnection to the tendons of the flexor digitorum longus at the master knot of Henry, deformities of the second and third toes are sometimes seen. There is no standard surgical treatment for checkrein deformity. Surgical release of the FHL muscle or release/lengthening of the FHL tendon has been proposed. The purpose of this Technical Note is to report the endoscopic release of the FHL tendon at the posterior ankle for management of checkrein deformity of the great toe, second toe, and third toe.

Causal Relationships Between Physical Activity and Arthrokinematic Integrity of the Ankle Joint-Foot Complex Across Normal and Pathological Phenomena: A Case-Control Analysis.
Introduction Muscles, ligaments, tendons, bones, and cartilage undergo age-related changes, affecting the foot-ankle joint complex biomechanics in both genders. While international studies have extensively researched these dynamics, Indian studies are limited. Our study aims to fill this gap by analyzing the anthropometric and biomechanical function of the foot-ankle joint complex in normal individuals and those with painful pathologies at All India Institute of Medical Sciences (AIIMS) Rajkot's OPD. Methods In a two-year case-control study of the cross-sectional type conducted at AIIMS Rajkot's OPD, 158 patients with similar pain intensity on the Numeric Pain Rating Scale were examined. Anthropometric and biomechanical measurements were taken for both affected and non-affected foot and ankle joints. Cases comprised patients with foot and ankle joint pain, while controls were selected based on predefined criteria and were without such pain. Ethical approval was acquired from the Institutional Ethical Committee of AIIMS Rajkot. Results The sprain of the ankle joint and foot was the most common musculoskeletal pathology (65 out of 158 cases, i.e., 41.13%) affecting the ankle joint-foot complex. Patients involved in occupations requiring higher physical inactivity suffer more commonly from ankle joint-foot pathologies. The mean difference in the range of motion, i.e., dorsiflexion, plantar flexion, inversion, and eversion, between affected and non-affected feet was found to be lower in the patients who belonged to occupations involving low physical activity compared to those patients having occupations with high physical activity. Conclusion Reduced physical activity increases the stiffness and reduces the flexibility of the tendons, muscles, and ligaments of any joint (the ankle joint-foot complex in this study) and is associated with a higher incidence of musculoskeletal pathologies.

Osteochondromas arising from the interosseous border of the distal tibia are rare, but cases have been reported previously in the literature. In long-standing cases, they can cause a "mass effect" resulting in the deformation of the bones around the ankle joint, mechanical restriction of joint movement, and even degenerative joint disease. Hence, they need to be resected if patients present with such impending complications. Several surgical techniques have been described previously for tumor resection including the anterior approach and the trans-fibular approach, the latter of which required a fibular osteotomy with or without fibular reconstruction. The surgical technique described here utilizes the posterolateral approach to the ankle joint for tumor excision, thus avoiding the need for any osteotomy or fibular reconstruction and reducing the risk of injury to major neurovascular structures. It also reduces the need for long-term immobilization and promotes a faster return to activity.

Animals have been used as models to help to better understand biological and anatomical systems, and pathologies in both humans and non-human species, and sheep are often used as an experimental model for orthopedic research. Gait analysis has been shown to be an important tool in biomechanics research with clinical applications. The purpose of this study was to perform a kinematic analysis using a tridimensional (3D) reconstruction of the sheep hindlimb. Seven healthy sheep were evaluated for natural overground walking, and motion capture of the right hindlimb was collected with an optoelectronic system while the animals walked in a track. The analysis addressed gait spatiotemporal variables, hip, knee and ankle angle and intralimb joint angle coordination measures during the entire walking cycle. This study is the first that describes the spatiotemporal parameters from the hip, knee and ankle joints in a tridimensional way: flexion/extension; abduction/adduction and inter/external rotation. The results of this assessment can be used as an outcome indicator to guide treatment and the efficacy of different therapies for orthopedic and neurological conditions involving the locomotor system of the sheep animal model.

Clinical Trial
INTRODUCTION
Charcot arthropathy is a progressive disorder of the ankle and foot joints that can lead to foot deformity and instability. Surgical intervention is often necessary for deformity and ulcer management during the chronic phase. The device used for arthrodesis remains a challenge.
METHODS
This clinical trial study included diabetic patients aged 40 years or older with Charcot foot. Lateral approach with lateral malleolar osteotomy was used to access the ankle joints and remove the cartilage. A small incision was made on the plantar aspect of the foot to pass an appropriately sized intramedullary nail. Demographic information, medical history, surgical details and Clinical data were collected at 2-week and 1-year follow-ups using the Ankle-Hindfoot Scale (AOFAS) score and the EuroQol 5-Dimensional 5-Level (EQ-5D-5L) health utility score.
RESULTS
Twenty-six patients with a mean age of 63 ± 0.23 years were included in the study. The findings showed significant improvements in AOFAS questionnaire items related to pain score, length of the walk, walking surfaces, walking disorders, sagittal alignment, back leg alignment, sustainability, alignment and the total score (P value < 0.001). The EQ-5D-5L questionnaire also showed a significant improvement in the total score (P value = 0.002).
CONCLUSION
This study provides evidence supporting the effectiveness of tibiotalocalcaneal arthrodesis by hindfoot nailing in diabetic patients with Charcot foot joints and demonstrated comparable and superior outcomes in terms of patient satisfaction and complication rate when compared to previous studies.

Review
Bosworth fracture (BF) is a special type of locked ankle fracture-dislocation, characterized by displacement of a fragment of the fractured fibula from the fibular notch behind the posterior surface of the distal tibia. BF is a complex injury affecting multiple structures of the ankle joint, which is still frequently misjudged even today, potentially leading to severe complications. CT examination, including 3D reconstructions, should be the diagnostic standard in BF, as it provides a complete picture of the fracture pathoanatomy, most prominently the morphology of the frequently associated posterior malleolar fracture. BF requires early reduction of the displaced fibular fragment without repeated attempts on closed reduction. Non-operative treatment of BF almost always fails. The standard treatment procedure is early open reduction internal fixation. Due to the relative severity and paucity of the injury, BF seems to be particularly prone to soft tissue complications, including compartment syndrome. The results of operative treatment are mixed. Many studies report persistent pain even after a short time interval, with limitations of the range of motion or even stiffness of the ankle joint, and development of degenerative changes. Larger studies with long-term results are still missing.

Reconstructive surgery after distal fibular resection due to bone tumors: a technical report on surgical strategies and results from the PROSPERO international register of systematic reviews.
PURPOSE
Primary bone tumors of the fibula are rare. Distal fibular resection has a significant impact on ankle biomechanics and gait, possibly leading to complications such as ankle instability, valgus deformity, and degenerative changes. Question: Is there a need for reconstructive surgery after distal fibular resection, and what reconstructive procedures are available?
MATERIALS AND METHODS
The review is registered with the PROSPERO International Register of Systematic Reviews. Inclusion criteria consisted of all levels of evidence, human studies, patients of all ages and genders, publication in English, and resection of the distal portion of the fibula due to tumor pathology. The reviewers defined four different categories of interest by method of treatment. Additional articles of interest during full-text review were also added.
RESULTS
The initial search resulted with a total of 2958 records. After screening, a total of 50 articles were included in the study. Articles were divided into 'No reconstruction', 'Soft tissue reconstruction', 'Bone and soft tissue reconstruction', and 'Arthrodesis, arthroplasty or other reconstruction options' groups.
CONCLUSION
Limb salvage surgery should be followed by reconstruction in order to avoid complications. Soft tissue reconstructions should always be considered to stabilize the joint after fibular resection. Bone reconstruction with reversed vascularized fibula is the preferred technique in young patients and in cases of bone defects more than 3 cm, while arthrodesis should be considered in adult patients. Whenever possible for oncologic reason, if a residual peroneal malleolus could be preserved, we prefer augmentation with a sliding ipsilateral fibular graft.

Comparative Study
BACKGROUND
To compare radiographic union and clinical outcomes between parallel and angulated screw configurations (SCs) for patients undergoing subtalar arthrodesis due to posttraumatic subtalar arthritis (PSA) after displaced intra-articular calcaneal fractures.
METHODS
This study retrospectively reviewed 140 consecutive PSA cases from March 2011 to November 2021 (parallel SC: group 1, n = 80; angulated SC: group 2, n = 60). Radiographic union, Foot and Ankle Outcome Score (FAOS), and visual analog scale (VAS) scores were among the outcome assessments. Six months after surgery, nonunion was confirmed based on plain radiographs, clinical evaluation, and computed tomography.
RESULTS
Groups 1 and 2 included 14 (17.5%) and 3 (5.0%) nonunion cases, respectively (p = 0.035). There was no significant difference in preoperative FAOS and VAS scores between the groups. However, group 2 had significantly better clinical outcomes in 2 of the 5 FAOS domains (sports and quality of life), as well as VAS scores at 3 and 6 months postoperatively and at the final follow-up ( < 0.05).
CONCLUSIONS
Using the angulated SC for PSA had a lower nonunion rate and superior clinical outcomes than the parallel SC. Obtaining better radiological and clinical outcomes when using the angulated SC, rather than the parallel SC, would be advantageous.

BACKGROUND
The Coronal Plane Alignment of the Knee (CPAK) classification system has been developed as a comprehensive system that describes 9 coronal plane phenotypes based on constitutional limb alignment and joint line obliquity (JLO). Due to the characteristics of Asian populations, which show more varus and wider distribution in lower limb alignment than other populations, modification of the boundaries of the arithmetic hip-knee-ankle angle (aHKA) and JLO should be considered. The purpose of this study was to determine the knee phenotype in a Korean population based on the original CPAK and modified CPAK classification systems.
METHODS
We reviewed prospectively collected data of 500 healthy and 500 osteoarthritic knees between 2021 and 2023 using radiographic analysis and divided them based on the modified CPAK classification system by widening the neutral boundaries of the aHKA to 0° ± 3° and using the actual JLO as a new variable. Using long-leg standing weight-bearing radiographs, 6 radiographic parameters were measured to evaluate the CPAK type: the mechanical HKA angle, medial proximal tibial angle (MPTA), lateral distal femoral angle (LDFA), aHKA, JLO, and actual JLO.
RESULTS
From 2 cohorts of 1,000 knees, the frequency distribution representing all CPAK types was different between the healthy and arthritic groups. The most common categories were type II (38.2%) in the healthy group and type I (53.8%) in the arthritic group based on the original CPAK classification. The left and upward shift in the distribution of knee phenotypes in the original classification was corrected evenly after re-establishing the boundaries of a neutral aHKA and the actual JLO. According to the modified CPAK classification system, the most common categories were type II (35.2%) in the healthy group and type I (38.0%) in the arthritic group.
CONCLUSIONS
Although the modified CPAK classification corrected the uneven distribution seen when applying the original classification system in a Korean population, the most common category was type I in Korean patients with osteoarthritic knees in both classification systems. Furthermore, there were different frequencies of knee phenotypes among healthy and arthritic knees.
