This expert consensus report summarizes the 2026 AANA/AOSSM/Biologic Association Think Tank proceedings identifying key research gaps and priority funding directions in orthobiologics for sports medicine.
In a rat Bankart model, adding PDGF to bone marrow stimulation dramatically boosted progenitor cell recruitment and improved labral healing and functional recovery compared to either treatment alone, suggesting a promising translational strategy.
In 30 patients after ACL reconstruction, knee extension deficits at 2 months were linked to worsening medial femoral cartilage T2 relaxation at 6 months, suggesting early ROM loss may accelerate cartilage degeneration and OA risk.
In 545 ankle arthroscopies, sensory nerve complications occurred in 8.4% of cases (mostly superficial peroneal nerve), with smoking and surgical approach as risk factors and less than half achieving full resolution by 13 months.
MRI T2* imaging showed ACL tissue changes across the menstrual cycle in eumenorrheic women but not in anovulatory controls, suggesting a possible hormone-related biomarker for ACL injury risk.
In patients with chronic ankle instability, delayed peroneal reaction time predicted increased ATFL ligament strain more strongly than peroneal muscle weakness, suggesting rehab should prioritize neuromuscular reaction training.
CT-based 3D modeling of 29 elbows found the ulnohumeral center of rotation closely matches the geometric center of the capitellum, guiding optimal graft placement for isometric lateral ulnar collateral ligament reconstruction.
In 50 patients, arthroscopic Bankart repair significantly shifted the humeral head posteriorly on MRI, with greater preoperative anterior translation (linked to instability chronicity) predicting less postoperative correction.
Examining Sex-Based Inequities in Pediatric Sports Medicine Research: A Systematic Review.
A systematic review of 409 pediatric sports medicine studies (2020-2024) found female athletes are significantly underrepresented, especially in single-sport and higher-evidence-level studies, highlighting a need for more equitable inclusion in future research.
A systematic review shows primary reverse total shoulder arthroplasty in patients under 65 significantly improves range of motion and PROMs, with modest complication (13%) and revision (8%) rates, supporting its use in selected younger patients.
In adolescents undergoing osteochondral autograft transplantation for capitellar OCD, preoperative proximal migration of the radial head >2.2mm independently predicted suboptimal outcomes.
In this cohort study, arthroscopic debridement outperformed ultrasound-guided lavage for Gärtner Type I calcific tendinitis, while both were equally effective for Type II, suggesting calcification type could guide treatment choice.
In selected proximal ACL tears, repair and hamstring reconstruction had similar clinical outcomes, but repair patients reported less joint awareness (higher FJS-12), which correlated with lower residual laxity.
In ACL-reconstructed knees, steeper tibial slope, flatter medial plateau, smaller lateral meniscal slope, and larger lateral femoral condyle ratio were linked to greater dynamic rotational/translational instability during jump-landing, suggesting possible indications for anterolateral augmentation.
Cadaveric study found FCL and ALL attachment distances shorten progressively with knee flexion while ITB Kaplan fiber segments remain relatively isometric, informing optimal graft fixation angles in lateral knee reconstruction.
In a rat chronic massive rotator cuff tear model, suprascapular nerve release combined with tendon repair improved biomechanical strength and histological healing compared to repair alone, supporting its potential clinical use.
Analysis of 677 astronaut shoulder injuries (1981-2024) found most occur post-flight, with longer microgravity exposure and greater NBL training hours linked to earlier injury onset, supporting targeted pre-flight conditioning and post-flight surveillance.
In this RCT of 150 rotator cuff repairs, longer surgical/suture exposure time predicted suture contamination more than choice of skin antiseptic, though olanexidine had higher contamination risk than alcohol-povidone-iodine.
In 699 patients, preoperative deficits in scaption and external rotation strength (plus age and Constant score) independently predicted rotator cuff retear, offering a practical clinical alternative to MRI for risk assessment.
In over 7,000 adolescents undergoing sports surgery, preoperative mood disorders did not increase complication rates but were linked to significantly lower postoperative follow-up attendance.
A narrative review guiding selection of patient-reported outcome measures for knee arthroscopy, emphasizing validity, ceiling effects, and clinically meaningful thresholds like MCID and PASS over statistical significance alone.
Arthroscopic study of 40 pediatric cadaver knees establishes normal age-based meniscal mobility and rim width benchmarks, showing the lateral meniscus is inherently more mobile than the medial, to help surgeons judge abnormal peripheral rim instability during discoid meniscus saucerization.
An expert RAND/UCLA consensus finds surgical choice for knee cartilage lesions in footballers should be tailored to lesion characteristics and patient priority for quick return vs long-term results, favoring debridement+orthobiologics or regenerative techniques respectively while bone marrow stimulation is often inappropriate.
Most injectable peptides marketed for sports medicine (aside from GLP-1 agonists for knee OA-related weight loss) remain experimental with unproven efficacy, safety concerns, and antidoping risks.
Osteochondritis Dissecans of the Elbow: Current Diagnosis and Management.
Reviews diagnosis and staged management of elbow osteochondritis dissecans, favoring nonoperative treatment for stable lesions and surgery (microfracture, OAT, grafting) for unstable or refractory cases.
The Orthopaedic Surgeon's Guide to Surfing Injuries.
A review outlining surfing biomechanics, typical orthopaedic injury patterns, prevention strategies, and return-to-sport guidance to help surgeons manage surfing-related injuries.
Management of the in-season athlete with an anterior shoulder dislocation.
This narrative review highlights that nonoperative treatment allows in-season return to play after shoulder dislocation but carries higher recurrence risk, while operative treatment lowers recurrence at the cost of season-ending recovery.
This award-winning research identifies Hedgehog signaling as a key driver of enthesis fibrocartilage formation and tendon-to-bone healing, offering a promising therapeutic target to improve outcomes after ACL and tendon repairs.
This review familiarizes orthopaedic surgeons with pickleball's rapid growth and common injuries, treatment, and prevention strategies given limited existing research.
Proximal patellar realignment and MPFL reconstruction show similar dislocation and arthritis rates, but PPR is cheaper and has fewer complications, so it remains a valid option for patellar instability.
Subtle Syndesmotic Instability.
This review covers diagnosis and management of subtle syndesmotic instability (high ankle sprains), emphasizing physical exam maneuvers, advanced imaging, and arthroscopic stress testing as the diagnostic gold standard.
Injuries in Male and Female Wrestlers.
Female wrestlers experience more sprains/strains while males have more concussions and fractures, with weight-cutting practices flagged as a shared concern needing further study.
