In a 46-patient RCT, MPFL reconstruction with a hybrid graft gave better knee scores at 3 and 6 months than autograft, but outcomes were equivalent by 12 months.
In a 240-patient RCT of grade I-II knee OA, a standardized multicomponent PRP pathway beat conventional PRP care on 12-month pain and function with fewer adverse events, but bundled components and no placebo arm mean PRP efficacy itself isn't established.
In a randomized sham-controlled trial of 52 healthy students, PEMF therapy after induced muscle soreness improved pain, pressure threshold, function, and muscle damage markers compared with sham.
At 5 years, allogeneic umbilical cord blood MSC-hyaluronate implantation beat microfracture for knee osteoarthritis on pain and function scores, with more durable MRI-defined repair tissue (62.5% vs 26.3%).
After arthroscopic Bankart repair, larger glenoid chondral lesions and lesions left uncovered by the repaired labrum independently predicted radiographic osteoarthritis at 2+ years (7% vs 40% vs 67% by lesion extent).
In 91 patients after medial meniscus posterior root repair, preoperative subchondral insufficiency fracture predicted fewer meaningful clinical improvements, more reoperations (20.6% vs 5.3%), and greater osteoarthritis progression.
Delayed return to sport after fat pad debridement: A surgical effect or a load-tolerance signal?
This letter argues that delayed return to sport after fat pad debridement may reflect a more irritable anterior knee pain phenotype and load tolerance needs rather than a surgical effect, calling for prospective, criterion-based studies.
In 26 professional soccer players, apparent diffusion coefficient on MRI fell about 22% over two weeks of muscle injury healing, with a greater decrease in females, suggesting ADC as a quantitative healing biomarker.
Commentary cautioning that a recent study lumped heterogeneous posterolateral tibial plateau fractures together, concluding only that their presence alone doesn't predict pivot-shift laxity, while high-grade lesions' significance remains unresolved.
A NATA Task Force: Preventing Exertional Heat Stroke Death in American Football Linemen.
Delphi-based NATA task force issues 20 consensus recommendations to reduce exertional heat stroke in football linemen, including acclimatization, weather-based modifications, position-specific work-to-rest ratios, and on-site cooling.
At 10+ years after hip arthroscopy, patients with femoral head cartilage lesions had patient-reported outcomes comparable to matched controls but double the rate of conversion to total hip arthroplasty (23.4% vs 11.7%).
BPC-157, thymosin beta-4, and TB-500 have only preclinical musculoskeletal evidence, scant human data, product-quality and antidoping concerns, and no approved indication, so routine orthopaedic use isn't recommended; clinicians should ask about use and counsel patients.
In a 10-knee cadaveric study, varying the femoral fixation point or fixation flexion angle of lateral extra-articular tenodesis did not change ACL graft force or knee motion; LET reduced graft load but overconstrained rotation.
In 482 sport-related ACL reconstructions, contact injury mechanism independently predicted greater structural injury severity on the ACLISS (OR 2.68), while sport category did not, so document the mechanism.
At a minimum of 5 years, arthroscopic FAI surgery in adolescents with borderline dysplasia was safe and effective, achieving MCID and PASS rates comparable to adolescents without dysplasia, though some outcome scores were slightly lower.
In 22 football players, high head-impact exposure was linked to worsening bimanual coordination over one season, though imaging changes and symptom scores showed no meaningful group differences.
In 33 ACL-injured patients versus matched controls, inflammatory and cartilage-turnover serum biomarkers stayed abnormal through the first year after reconstruction, suggesting the biological response outlasts surgery and standard rehabilitation.
The Deep Medial Collateral Ligament, Part 1: Quantitative, Qualitative, and Radiographic Anatomy.
Cadaveric mapping of the deep MCL showed a broad, consistent footprint with anteromedial capsular extension beyond the classic midthird region, giving landmarks and radiographic references to guide medial knee reconstruction.
In 743 knee OA patients, PRP injection was associated with improved pain and function at 6 months and 1 year across KL grades, but the uncontrolled design means causation cannot be inferred.
This review traces a two-decade bench-to-bedside program on PCL injuries, from cadaveric anatomy and robotic biomechanics to objective diagnostics and anatomic double-bundle reconstruction that restored stability comparable to ACL reconstruction.
In patients 24 or younger with minimal glenoid bone loss, arthroscopic Bankart repair had a 33% recurrence rate and 20% revision rate, with contact sports predicting failure; only 57% returned to preinjury level.
In 40 anterior instability patients, the global track angle only modestly predicted off-track Hill-Sachs lesions (AUC 0.65), with a cutoff near 66 degrees, so it needs larger validation before clinical use.
At 10+ years, all-inside 4-stranded semitendinosus ACL reconstruction had a 20.5% graft failure rate despite good patient-reported outcomes; higher preoperative Tegner level trended toward more failures.
Arthroscopic particulated juvenile cartilage implantation for full-thickness knee lesions gave significant improvements at 24+ months in 34 patients, with one late delamination; higher BMI predicted worse outcomes.
In a large claims database, Latarjet had a lower 2-year reoperation rate than anterior free bone block (8.7% vs 13.4%), with similar nerve injury rates, though bone block patients were older and sicker.
In a rat model, single-hole microfracture healed best in defects up to about 1.5 mm, with repair tissue concentrated around the perforation and fading peripherally, suggesting limited coverage from one microfracture channel.
In 187 collegiate pitchers followed over one summer, arm injury risk rose with increases in game pitch count and with decreases in fastball velocity relative to each pitcher's own average.
Timing Matters: Assessing Fatigue During and After Resistance Training.
In 13 trained athletes doing squats, the timing and method of measuring jump-based fatigue changed results; use average values within training and maximum values at least 10 minutes after training for reliable assessment.
Interviews with 10 elite sports medical staff found major knowledge gaps, regulatory uncertainty, and stigma limiting cannabis guidance for athletes, underscoring the need for education, research, and clear league policies.
This review proposes a treatment algorithm for talar osteochondral lesions, matching fragment fixation, marrow stimulation, osteochondral transplantation, cell-based repair, or salvage procedures to lesion size, cartilage and bone quality, and prior surgery.
Technical note describing a reproducible all-arthroscopic technique for implanting an aragonite-based osteochondral scaffold in femoral trochlear defects, avoiding mini-arthrotomy, with pearls and pitfalls specific to the patellofemoral joint.
Lipid Profiles in Elite and Collegiate Athletes: A Scoping Review.
Scoping review of 31 studies (5,921 athletes) finds lipid profiles in elite and collegiate athletes vary by sex, sport, and competitive level, with women underrepresented and a need for standardized studies.
Scoping review of 26 studies finds bridge-enhanced ACL repair gives knee stability and patient-reported outcomes comparable to reconstruction at 2 years with better early hamstring strength, but long-term durability data are lacking.
ESSKA-ESA expert consensus finds that patient age and first-time versus recurrent dislocation should guide history, physical exam, and imaging choices in traumatic anterior shoulder instability, with 12 statements mostly graded B.
Lumbar Spine Injuries in Recreational Athletes: A Review.
Review of lumbar spine injuries in recreational athletes (disk herniation, spondylolysis, disk degeneration), noting most do well with nonsurgical care, and surgery after failed conservative treatment allows return to sport.
Anatomic or reverse shoulder arthroplasty for cuff intact glenohumeral osteoarthritis.
This paper describes the rationale and design of the RAPSODI trial, which will compare anatomic versus reverse shoulder arthroplasty, including cost effectiveness, for glenohumeral osteoarthritis with an intact rotator cuff.
International Delphi consensus recommends adding a lateral extra-articular procedure to ACL reconstruction in young active patients with hamstring grafts, high-grade pivot shift, hyperextension, revision, or return to pivoting sports; several questions remain unresolved.
Athlete's Mental Health and Quality of Life After Sports Injuries.
Psychological factors shape both injury risk and recovery; postinjury distress slows rehabilitation, female athletes fare worse, and integrating psychological support into rehab improves outcomes.
Adhesive Capsulitis of the Shoulder.
Review of adhesive capsulitis: most cases resolve without surgery using PT, early or low-dose steroid injections, or hydrodilatation; arthroscopic release or manipulation under anesthesia is considered after 9 to 12 months of failed conservative care.
Ammonia Inhalants: Use, Misuse, and Role in Sports Performance.
Review finds ammonia inhalants offer limited performance benefit (only in repeated high-intensity bouts) and have no role in head injury management, since they may mask concussion symptoms and keep athletes in play.
The Principles of Hip Joint Preservation.
This review explains that hip preservation depends on addressing femoroacetabular impingement, dysplasia/instability, and femoral torsion abnormalities, and that surgeons should treat all contributing factors rather than only the visible injury such as a labral tear.
