Background: A critical component of conducting systematic reviews or meta-analyses is assessing the methodological quality and bias of included studies. Several methodological quality assessment tools have been developed; however, these tools may not be relevant to observational sports medicine research, which carries numerous unique nuances and biases. Purpose: To develop the Sport Publication Observational Research Tool (SPORT), which evaluates and scores the methodological quality of observational sports medicine research. Study Design: Consensus statement. Methods: SPORT was developed through a modified Delphi approach involving members from the Herodicus Society and The FORUM. All active members were invited to participate in the process aimed at building consensus on SPORT content and scoring. After finalizing SPORT, a power analysis led to the independent selection of 55 observational clinical sports medicine studies, which were scored twice by 4 reviewers of varying training levels. Interrater and intrarater reliability for SPORT was assessed using intraclass correlation coefficients (ICCs). The distribution and percentiles for total SPORT score across the 55 studies were calculated. SPORT was also compared with the methodological index for non-randomized studies (MINORS), a commonly utilized quality assessment tool. Results: A total of 51 members participated and achieved 100%, 100%, 98.0%, and 98.0% completion rates for rounds 1 through 4, respectively. The final SPORT included 19 subscores related to methodological quality and bias and achieved 94% consensus approval. Mean SPORT completion time was 6 minutes and 19 seconds per study, which varied significantly by reviewer training level. The subscore "peer review" demonstrated unacceptable reliability and was removed. The remaining 18 subscores exhibited ICC ranges of 0.599 to 0.955 for interrater reliability and 0.530 to 0.936 for intrarater reliability. Total SPORT score demonstrated excellent agreement, for interrater (ICC, 0.967) and intrarater reliability (ICC, 0.966). Median SPORT score across the 55 studies was 20.0 and skewed toward lower scores. There was a moderate significant correlation between SPORT and MINORS ( r [53] = 0.575; P < .001). Conclusion: An objective tool to assess the methodologic quality of observational sports medicine research (SPORT) was successfully developed through a modified Delphi approach with numerous content experts in the field. This tool may be useful in assessing the methodological quality of primary observational sports medicine studies included in systematic reviews and meta-analyses.

Purpose To assess the ability of ChatGPT‐4, an automated Chatbot powered by artificial intelligence, to answer common patient questions concerning the Latarjet procedure for patients with anterior shoulder instability and compare this performance with Google Search Engine. Methods Using previously validated methods, a Google search was first performed using the query “Latarjet.” Subsequently, the top 10 frequently asked questions (FAQs) and associated sources were extracted. ChatGPT‐4 was then prompted to provide the top 10 FAQs and answers concerning the procedure. This process was repeated to identify additional FAQs requiring discrete‐numeric answers to allow for a comparison between ChatGPT‐4 and Google. Discrete, numeric answers were subsequently assessed for accuracy on the basis of the clinical judgment of 2 fellowship‐trained sports medicine surgeons who were blinded to search platform. Results Mean (± standard deviation) accuracy to numeric‐based answers was 2.9 ± 0.9 for ChatGPT‐4 versus 2.5 ± 1.4 for Google ( P = .65). ChatGPT‐4 derived information for answers only from academic sources, which was significantly different from Google Search Engine ( P = .003), which used only 30% academic sources and websites from individual surgeons (50%) and larger medical practices (20%). For general FAQs, 40% of FAQs were found to be identical when comparing ChatGPT‐4 and Google Search Engine. In terms of sources used to answer these questions, ChatGPT‐4 again used 100% academic resources, whereas Google Search Engine used 60% academic resources, 20% surgeon personal websites, and 20% medical practices ( P = .087). Conclusions ChatGPT‐4 demonstrated the ability to provide accurate and reliable information about the Latarjet procedure in response to patient queries, using multiple academic sources in all cases. This was in contrast to Google Search Engine, which more frequently used single‐surgeon and large medical practice websites. Despite differences in the resources accessed to perform information retrieval tasks, the clinical relevance and accuracy of information provided did not significantly differ between ChatGPT‐4 and Google Search Engine. Clinical Relevance Commercially available large language models (LLMs), such as ChatGPT‐4, can perform diverse information retrieval tasks on‐demand. An important medical information retrieval application for LLMs consists of the ability to provide comprehensive, relevant, and accurate information for various use cases such as investigation about a recently diagnosed medical condition or procedure. Understanding the performance and abilities of LLMs for use cases has important implications for deployment within health care settings.

Background: Quantitative magnetic resonance (qMR) can be used to measure macromolecules in tissues and is a potential method of observing early cartilage changes in the development of posttraumatic osteoarthritis. Hypothesis/Purpose: We hypothesized that specific patient and surgical factors affecting cartilage matrix composition after anterior cruciate ligament (ACL) reconstruction (ACLR) can be detected using T1ρ and T2 relaxation times. Our purpose was to demonstrate this ability in a multicenter feasibility study. Study Design: Case series; Level of evidence, 4. Methods: A total of 54 patients who underwent ACLR underwent bilateral MRI at baseline before surgery and 6 months postoperatively. Operative findings were recorded. T1ρ and T2 relaxation times were calculated for 6 cartilage regions: the medial femur, lateral femur, medial tibia, lateral tibia, patella, and trochlea. A paired t test compared relaxation times at baseline and 6 months, univariate regression identified regions that influenced patient-reported outcome measures, and analysis of covariance was used to determine the surgical factors that resulted in elevated relaxation times at 6 months. Results: The injured knee had significantly prolonged T1ρ and T2 relaxation times in the tibiofemoral compartment at baseline and 6 months but had shorter values in the patellofemoral compartment compared with the uninjured knee. Prolonged T1ρ and T2 times at 6 months were noted for both the injured and uninjured knees. At 6 months, prolongation of T1ρ and T2 times in the tibial region was associated with lower patient-reported outcome measures. ACLR performed within 30 days of injury had significantly shorter T1ρ times in the tibial regions, and lateral meniscal tears treated with repair had significantly shorter T1ρ times than those treated with excision. Conclusion: Prolonged relaxation times in multiple regions demonstrate how the injury affects the entire joint after an ACL tear. Changes observed in the uninjured knee may be caused by increased loading during rehabilitation, especially in the patellofemoral articular cartilage and distal femur. Relaxation times in the tibial regions may be predictive of patient symptoms at 6 months. These same regions are affected by surgical timing as early as 30 days after injury, but this may partially be reflective of the severity of the preoperative injury and the choice of treatment of meniscal tears.

Abstract We present our technique for isolated arthroscopic rotator interval closure in the treatment of mild symptomatic glenohumeral instability in the absence of a labral tear. A careful history, physical examination, and imaging help to identify a select subset of atraumatic instability patients who may benefit from this procedure, and diagnostic arthroscopy can provide further evidence. By use of a posterior viewing portal with anterior and anterolateral working portals, the anterior capsuloligamentous complex is mobilized, and the rotator interval is closed with carefully placed sutures to advance the capsule superiorly and provide tension through decreased capsular volume.

Background The triceps tendon has been described as a single unit with contribution from each of the 3 heads of the muscle. An observation at the time of surgical repair of a triceps tendon injury led to an anatomical study to further define the anatomy of this tendon as it inserts on the olecranon. Hypothesis The medial head of the triceps has a tendon that is distinct from, and deep to, the common tendon of the long and lateral heads. Study Design Descriptive laboratory study and case report. Methods Eight cadaveric elbows were dissected to examine the triceps tendon. None of the specimens had any evidence of prior injury or surgery to the elbow. All specimens were fresh-frozen and stored at–4°C until they were thawed for use. Skin and subcutaneous tissue were removed, and the tendon of each head of the triceps was explored from the muscle to its bony insertion. Results In all 8 specimens, on gross inspection, the medial head had a separate insertion deep to the common insertion of the lateral and long heads. The muscle of the medial head extended further distally than did the long and lateral heads. The medial head was muscular to its deep insertion, with a small amount of tendon blended with the muscle distally. Histologic analysis demonstrated that the tendon of the medial head and that of the other 2 heads are confluent distally at their olecranon insertion. Conclusion The medial head of the triceps has a tendon that is distinct from, and deep to, the common tendon of the long and lateral heads on gross inspection. Histologic studies show the insertion of these 2 tendons is confluent. Clinical Relevance This anatomy has important implications for surgical repair of these tendon injuries. Rupture of the deep triceps insertion alone can occur and lead to weakness of elbow extension with the elbow flexed beyond 90°. Triceps strength should be tested with the elbow fully flexed when injury to the tendinous insertion is suspected.

Abstract A review of the literature reveals that surgical treatment of coracoid impingement has heretofore involved open surgical decompression in all cases. Previously unreported, the authors describe an arthroscopic technique to treat coracoid impingement syndrome, demonstrate its feasibility, and cover the specific technical points that facilitate this procedure.
