Hip arthroscopy is a surgical procedure that has a technically challenging nature, requiring advanced spatial skills and specialised instrumentation. The most common indication for hip arthroscopy is femoroacetabular impingement, which is increasing due to improved awareness and knowledge of the condition among healthcare professionals. Hip arthroscopy requires many different checkpoints from patient positioning to capsule closure to be successfully completed. Patient positioning is one of the keystones of hip arthroscopy and the probability of a surgeon achieving successful outcomes is significantly influenced by the establishment of optimal access points. The importance of the acetabular labrum and capsule has been better understood in recent years. There has been a noticeable preference towards prioritising acetabular labral repair over debridement or excision. Similarly, consistent with the literature, capsule closure restores naive hip biomechanics more successfully and improves functional outcomes following hip arthroscopy. Osteochondroplasty is a frequently employed therapeutic intervention; yet, attaining optimal osteochondroplasty outcomes might present challenges. The aim is, to restore the full perfect sphericity of the femoral head without attenuation of the head. The aim of this article is to highlight the knowledge accumulated from experiences based on previous hip arthroscopy surgeries as a solution for future troubleshooting steps.Level of Evidence: Level V.

Background: Simultaneous repairs of rotator cuff and biceps tenodesis can be managed by tenodesis of long head of biceps tendon to a subpectoral or suprapectoral area. This review investigated long head of biceps tendon tenodesis with concomitant rotator cuff repair and evaluated the clinical outcomes and incidences of complications based on tenodesis location. Methods: Medline, Cochrane, and Embase databases were searched for published, randomized or nonrandomized controlled studies and prospective or retrospective case series with the phrases “suprapectoral,” “subpectoral,” “tenodesis,” and “long head of biceps tendon”. Those with a clinical evidence Level IV or higher were included. Non-English manuscripts, review articles, commentaries, letters, case reports, and sole long head of biceps tendon tenodesis articles were excluded. Results: From 481 studies, 13 were chosen. In total, 1194 subpectoral and 2520 suprapectoral tenodesis cases were investigated. Postoperative Constant-Murley and American Shoulder and Elbow Surgeons mean scores showed similar good results. In terms of complication incidences, while transient nerve injuries were more commonly seen in patients with subpectoral tenodesis, persistent bicipital pain and Popeye deformity are mostly seen in patients with suprapectoral tenodesis. Discussion: Biceps tenodesis to suprapectoral or subpectoral area with concomitant rotator cuff repair demonstrated similar outcomes. Popeye deformity and persistent bicipital pain were higher in suprapectoral area and transient neuropraxia was found to be higher in subpectoral area. Level of evidence: IV.

Objective: Three computed tomography (CT)-based classifications, including Haraguchi, Bartoníček–Rammelt, and Mason–Molloy systems, have been developed to better determine the characteristics of posterior malleolus fractures (PMFs). The aims of this study were (1) to determine the intra- and inter-observer reliability of the computed tomography-based classification systems and (2) to investigate the clinical experience and expertise on their reliabilities. Methods: Sixty-seven preoperative ankle CT scans of 67 adult patients with “ankle fracture with the involvement of the posterior malleolus”’’ were retrospectively identified. CT images were assessed by 10 observers with different levels of clinical experience from 2 different specialties, including orthopedics and radiology. The observers were asked to classify PMFs according to 3 CT-based classifications on 2 separate occasions with a 4-week interval. Cohen’s κ values were measured for 2 raters and Fleiss’ κ values were measured for 3 raters and more. Results: Overall, each classification had moderate to very good intraobserver reliability (κ=0.41 to 0.95, P < .01) as well as moderate interobserver reliability for each of the 2 separate assessments (κ=0.41 to 0.60, P < .01 for the first occasion; κ=0.44 to 0.59, P < .01 for the second occasion). Interobserver agreement among the foot and ankle surgeons regarding the Haraguchi and Bartoníček classifications was substantial for both assessment periods, whereas there was a moderate agreement for the Mason classification. Orthopedic residents showed moderate interobserver agreement in each period for both Bartoníček and Mason classifications. Radiology experts illustrated slight and fair agreements in the 2 assessments for Mason classification, moderate agreement in both assessments for Haraguchi classification, and substantial to moderate agreement in the first and second assessments for Bartoníček classification, respectively. Conclusion: Computed tomography-based classification system for PMFs demonstrated moderate interobserver reliability as well as moderate to very good intraobserver reliability. Moreover, foot and ankle specialists exhibit enhanced K values for both inter and intraobserver reliability for each classification system, consistency seems to increase as the interest in the field condenses. Level of Evidence: Level III, diagnostic study.

Background: Multiligament knee reconstruction is a technically demanding procedure with a steep learning curve and carries the potential for significant complications if technical accuracy is not achieved. Although optimal tunnel trajectories to prevent convergence have been described, it remains unclear how accurately these theoretical trajectories are executed in practice and whether patient-specific guides can improve precision and reduce tunnel convergence. Purpose: To evaluate the effectiveness of patient-specific guides in preventing tunnel convergence and improving surgical accuracy in multiligament knee reconstruction. Study Design: Controlled laboratory study. Methods: Computed tomography scans from a single case were used to create accurate 3-dimensionally printed femur models. Each of the 8 participating orthopaedic surgeons performed tunnel placement on 2 models: 1 using the freehand technique and 1 using a custom-designed guide. Tunnels of the anterior cruciate ligament (single bundle) and posterior cruciate ligament (double bundle consisting of the anterolateral and posteromedial bundles) were constant. Surgeons created femoral tunnels for posterolateral structures (fibular collateral ligament, popliteus tendon) and posteromedial structures (medial collateral ligament, posterior oblique ligament). Postprocedure computed tomography was used to assess tunnel convergence, intertunnel distances (>2 mm defined as safe), and tunnel entry accuracy. Results: Lateral tunnel convergence occurred in 11 of 16 tunnels via freehand—primarily between the popliteus tendon and anterior cruciate ligament (7/8)—and none of the patient-specific guide models (0/16; P = .001). Medial convergence was reduced from 10 of 16 via freehand to 2 of 16 via the guide ( P = .001), most commonly between the posterior oblique ligament and posterior cruciate ligament–posteromedial bundle. Mean intertunnel distances were significantly greater via the guide. Tunnel entry accuracy was 100% with the guide. Conclusion: The use of patient-specific guides significantly reduces tunnel convergence and improves tunnel entry point precision in multiligament reconstruction simulation. Freehand tunneling highlights the prominent influence of human error. Clinical Relevance: Surgical success in multiligament reconstruction relies on anatomic graft function, yet tunnel convergence may jeopardize graft integrity and lead to failure. Therefore, avoiding tunnel convergence is of utmost importance for a successful reconstruction.

The Dias-Tachdjian classification is the most commonly used system for the classification of pediatric ankle fractures, but its inter- and intra-observer reliability has not been studied in detail. Also, the impact of the clinician’s experience and expertise on the reliability of this system is unknown. This study aimed: (1) to determine the intra- and inter-observer reliability of the Dias-Tachdjian classification and (2) to investigate the effect of the clinician’s experience and expertise on the reliability of this system. Anteroposterior and lateral ankle radiographs of 56 children (34 male, 22 female) with ankle fractures, aged between 3 and 14 years, with open growth cartilages, were retrospectively identified and included in the study. Each patient radiograph was examined by 10 observers from two different specialties with different levels of clinical experience (two orthopedic surgeons with interest in pediatric orthopedics, three orthopedic surgeons with no interest in pediatric orthopedics, three orthopedic residents, and two radiology specialists) from two different specialties (orthopedics and radiology). All observers were then asked to classify pediatric ankle fractures at 6-week intervals per the Dias-Tachdjian classification system. Overall, intra-observer reliability as substantial to very good (κ = 0.77–0.95, P < 0.01), but inter-observer reliability as fair for both assessments (κ = 0.21, P < 0.01 and κ = 0.20, P < 0.01 for the first and second occasions, respectively). Inter-observer reliability among pediatric orthopedic surgeons as very good (κ = 0.90, 95% CI = 0.86–0.94, P < 0.01 and κ = 0.82, 95% CI = 0.71–0.93, P < 0.01 for the first and second occasions, respectively). Orthopedic surgeons with no special interest in pediatric orthopedics demonstrated substantial agreement in the first occasion (κ = 0.63, 95% CI = 0.53–0.72, P < 0.01) but moderate in the second one. Orthopedic residents exhibited moderate levels of agreement in each assessment period (κ = 0.58, 95% CI = 0.47–0.68, P < 0.01 and κ = 0.44, 95% CI = 0.37–0.51, P < 0.01 for the first and second occasion, respectively). Considering that the specialists dealing with pediatric orthopedics show very good consistency for Dias-Tachdjian classification, both within and between observers, consistency in the identification of the ankle fracture models increases as the interest in the field of pediatric orthopedics intensifies.

Purpose The aim of this study was to assess the clinical and radiological outcomes of patients with recurrent or neglected pes equinovarus (PEV), who underwent talonavicular or calcaneocuboid arthrodesis with a hexapod spider frame. Methods The study included 18 patients; a total of 25 feet were treated with dual arthrodesis and a hexapod spider frame. The International Club Foot Study Group (ICFSG) scoring system and visual analog scale (VAS) were used to assess preoperative status and postoperative outcomes. All functional, morphological and radiologic evaluations during the follow-up were done as described by Kling et al. Results Patients were followed up for an average of 24.1 ± 11.8 months. The mean age of our cohort was 8.84 ± 2.83 years. The mean duration of correction was 3 weeks and the mean duration treatment length was 15.3 ± 1.9 weeks. Postoperative assessment revealed eight excellent, 13 good, and four poor outcomes, according to the ICFSG scoring system. There was a significant difference between preoperative and postoperative ICFSG scores, 12 feet showed an excellent outcome, 12 feet had good outcomes, and one foot was rated as a failure in the final assessment, based on the Kling criteria. There was also a significant difference between preoperative and postoperative VAS scores. Conclusion Dual arthrodesis plus a hexapod spider frame is a valuable option for patients with recurrent or neglected PEV. It can be offered safely to avoid secondary recurrences and potential complications in cases of rigid feet as well as challenging cases that are resistant to soft tissue manipulation.
