SUMMARY: Expert Delphi consensus supports meniscal centralization with root repair or allograft transplantation when MRI extrusion exceeds 3 mm, discourages it in advanced osteoarthritis, accepts various fixation constructs, and calls for long-term outcome data.

SUMMARY: In 44 knees after medial open-wedge high tibial osteotomy, outcomes improved at 2 years, but higher preoperative trochlear bone marrow lesion scores modestly predicted worse residual KOOS symptoms, useful for counseling.

SUMMARY: Technical note describing backfilling of patellar and tibial harvest defects with autologous bone reamings and ACL remnant tissue, with paratenon preservation, during BTB ACL reconstruction to potentially reduce donor site pain.

SUMMARY: In a small retrospective case-control study of 12 athletes, adding platelet-rich growth factor matrix to Achilles repair sped return of motion, running, and training with no wound complications, though randomized trials are needed.

SUMMARY: Reviews etiology, diagnosis, and treatment of osteochondral lesions of the talus and tibial plafond: nonoperative care first, then arthroscopic bone marrow stimulation or fixation, with open techniques for larger or secondary lesions.

SUMMARY: Capitellar OCD affects young athletes aged 10-24; MRI or CT beats radiographs for diagnosis, stable lesions with intact cartilage get non-operative care, and surgical options are chosen by patient, function, and lesion morphology.

SUMMARY: This review finds subsymptom-threshold aerobic exercise is safe and speeds recovery after sport-related concussion and reduces persistent symptoms, challenging strict rest, though optimal dosing remains unclear.

SUMMARY: Kim's lesion, an incomplete posteroinferior labral-glenoid tear with intact superficial labrum, is an under-reported cause of posterior shoulder pain and instability in young athletes, confirmed arthroscopically and fixed arthroscopically if nonoperative care fails.

SUMMARY: In 70 hips, traction MR arthrography had good sensitivity (75-86%) but poor specificity (32-52%) for ligamentum teres, fossa, and fovea lesions versus intraoperative findings, so preoperative detection is limited.

SUMMARY: In a porcine model, acetabular rim microfracture added to labral autograft reconstruction improved early vascularization, fibrocartilaginous remodeling, and integration; preclinical findings that require biomechanical and clinical validation.

SUMMARY: In a Markov cost-effectiveness model, quadriceps tendon and BPTB autografts offered the best value for ACL reconstruction, while hamstring autograft and allograft cost more and were less effective; graft choice should stay individualized.

SUMMARY: In 138 female collegiate athletes, preseason knee flexor strength asymmetry, hip extensor flexibility asymmetry, and low hamstring-to-quadriceps ratios were associated with more lower extremity injuries, suggesting screening value.

SUMMARY: Review of hamstring injuries in athletes: complete proximal avulsions generally warrant surgical repair with good outcomes, while most myotendinous injuries are managed nonsurgically despite frequent reinjury and delayed return to sport.

SUMMARY: International Delphi consensus reached agreement on 82% of statements for managing isolated meniscal tears in skeletally immature children, but not on small radial tears, chronic bucket-handle reduction, or surgical timing.

SUMMARY: International Delphi consensus defines core imaging for hip instability: radiographs first, then CT/MRI, with LCEA under 20° diagnostic of dysplasia and 20°-25° concerning for instability; newer dynamic and soft tissue measures lacked consensus.

SUMMARY: This narrative review covers Kaplan fibre anatomy, MRI assessment, and role in rotatory knee stability, linking their injury to high-grade pivot shift and supporting selective lateral extra-articular tenodesis with ACL reconstruction.

SUMMARY: In a 114-patient randomized trial, a single injection of autologous adipose-derived stromal vascular fraction gave a higher 12-month responder rate than placebo (52% vs 29%) in moderate-to-severe knee OA, with no serious device-related adverse events.

SUMMARY: At about 13 years after meniscus allograft transplantation, ultrasound extrusion was greater in transplanted menisci (especially medial) but did not correlate with IKDC scores or radiographic degeneration, so it is not a surrogate for outcomes.

SUMMARY: Seven psychologically loaded WOSI items correlated strongly with outcome scores after shoulder stabilization, and two items (15 and 17) tracked function and motion, suggesting a quick recovery screen.

SUMMARY: Economic model over 5 years finds adding biceps tenodesis to rotator cuff repair is cost-effective (ICER $13,064/QALY), favored in about 89% of simulations despite higher upfront cost.

SUMMARY: In cadaveric testing, the deep MCL failed at about 243 N, usually in its meniscotibial portion, providing reference strength data for medial knee reconstruction and fixation planning.

SUMMARY: After hip arthroscopy for FAI, patients with congenitally narrow joint space (<3 mm) had similar cartilage quality and reoperation rates but worse 5-year patient-reported outcomes than matched controls.

SUMMARY: Meta-analysis of 16 observational studies (664 patients) found low graft failure (1.7%) and complication rates after anterior closing wedge HTO with ACL reconstruction, with no clear differences by surgery type or osteotomy level, though evidence certainty is very low.

SUMMARY: Review of core stability (the lumbopelvic hip complex's ability to resist buckling and recover from perturbation), noting that poor core stability may predispose to back and lower extremity injury and that appropriate training may reduce it.

SUMMARY: In 146 professional soccer players, reduced preseason hamstring and quadriceps flexibility predicted later injury to those muscles, while adductor and calf flexibility did not.

SUMMARY: Review proposes a stepwise metabolic workup for athletes with bone stress injury: all get vitamin D, CBC, and iron studies, with DXA and broader testing for low energy availability, recurrent injuries, or surgical cases.

SUMMARY: Narrative review of 21 papers proposes a training model for athletes with extended careers, emphasizing expertise, injury history, strength training, load monitoring, and avoiding load spikes and inactivity.

SUMMARY: In human tissue and a mouse overuse model, the succinate-SUCNR1 axis drove rotator cuff tendon degeneration and weakness, and blocking it protected tendon strength, suggesting a possible future strategy to reduce retears.

SUMMARY: In 42 reverse shoulder arthroplasties after failed cuff surgery, pseudoparalytic shoulders improved markedly in elevation, but results were inferior to primary RSA and painful shoulders with preserved elevation fared worse.

SUMMARY: In 80 reverse shoulder arthroplasties followed at least five years, prosthesis survival was 91% at 10 years but function declined; use should be limited to disabling cuff-tear arthropathy in low-demand patients over 70.
