Pyrocarbon interposition shoulder arthroplasty maintains 87% 10-year survival in post-traumatic and post-instability osteoarthritis; biconcave glenoid increases failure risk.
Clinical and radiographic outcomes following open Latarjet with single button technique.
Open Latarjet with single-button fixation demonstrated safe, effective stabilization with no recurrences and fewer implant-related complications than double-screw techniques.
Synovial inflammatory phenotypes at ACL reconstruction with meniscal injury predict baseline severity and differential recovery patterns; phenotype-dependent biomarker associations guide prognostication.
Central acetabular osteophytes in borderline hip dysplasia associate with microinstability and increased version abnormalities.
Adolescent coracoid morphology reaches adult dimensions by age 14, supporting feasibility of adult dual-fixation techniques in Latarjet procedures for shoulder instability.
Bilateral native ACL rupture independently increases ACL graft failure risk to 9.3% versus 5.2% for unilateral injuries, indicating intrinsic vulnerability to ligament injury.
Latarjet with inverted L-shaped tenotomy preserves subscapularis function at 10+ years with minimal fatty infiltration.
Arthroscopic prior rotator cuff repair and longer intervals before reverse shoulder arthroplasty independently predict better postoperative function and motion recovery.
Os subfibulare presence did not compromise modified Broström-Gould procedure outcomes; excision combined with repair is safe and effective.
Segmental and circumferential hip labral reconstruction yield comparable functional improvements, but circumferential technique shows lower conversion to THA rates.
Impact of the Lower Body on Softball Pitching Velocity.
Peak vertical center of mass velocity strongest predictor of softball pitch velocity; lower body training critical for velocity and injury prevention.
Meniscal Dominant Loaders During Simulated Gait: A Cadaveric Study in Human Knees.
Human cadaveric knees distribute joint contact forces heterogeneously during gait; meniscal-dominant loaders comprise 48% of knees with distinct peak stress patterns.
Bankart repair using Mason-Allen technique for small bony Bankart lesions achieves superior Rowe scores, high union rates, and low recurrence comparable to bone-block procedures.
Olympic basketball participation increases subsequent NBA injury rates and decreases availability without improving performance metrics.
Incidence of Lower Extremity Deep Vein Thrombosis Following Arthroscopic Rotator Cuff Repair.
Asymptomatic DVT occurs in 5.3% after rotator cuff repair; routine screening not recommended given distal location and asymptomatic presentation.
Preoperative GLP-1 agonist use in obese patients undergoing rotator cuff repair was associated with decreased revision and retear rates.
Nonsurgical and surgical ACL management achieve comparable knee function and return-to-sport rates at 24 months; individualized shared decision-making optimizes outcomes, especially for older or lower-activity patients.
Preoperative shoulder stiffness showed distinct inflammatory tendon signatures but not inferior long-term outcomes after rotator cuff repair.
Critical 3-6 month graft remodeling period after ACL reconstruction shows incomplete maturation; MRI monitoring may guide safer return-to-sport timing.
Germany shows 71% increase in outpatient ACL reconstruction with decreased overall incidence, signifying shift toward ambulatory care.
Open capsular shift with Achilles allograft augmentation provides durable shoulder stability in multidirectional instability, including EDS patients.
Computer navigation in reverse shoulder arthroplasty reduced early revision rates after 2017 introduction; no benefit demonstrated for anatomical arthroplasty.
Chronic ankle instability involves reduced cerebellar activation with reduced vision, associating with delayed peroneal reaction time.
Arthroscopic-Assisted Posterolateral Corner Reconstruction With Popliteus Tendon Repair.
Arthroscopic-assisted posterolateral corner reconstruction with popliteus tendon repair improves visualization and enables retensioning of popliteofibular ligament function restoration.
Bowtie Technique for Arthroscopic Hip Inversion Labral Repair.
Bowtie suture technique simplifies arthroscopic hip labral repair by improving suture control and restoring the labral suction seal mechanism reproducibly.
Static anterior tibial translation captures functional weight-bearing sagittal position reflecting osseous and soft-tissue anteriorization; distinct phenotypes guide targeted treatment strategies.
Generative AI in orthopaedics shows promise for clinical workflows and surgical planning but requires rigorous validation and addresses black-box concerns.
Postoperative stiffness and rotator cuff tendon healing: a narrative review.
Postoperative shoulder stiffness may paradoxically reflect enhanced healing response with lower retear rates due to elevated inflammatory cytokines.
Posterior medial meniscus root tear classifications lack consensus; MRI-based systems show good interobserver agreement but arthroscopy-validated accuracy remains limited.
Management of bone loss in anterior shoulder instability.
Glenoid bone loss below 20% still risks failure; combined bipolar lesions require remplissage and bone reconstruction.
High-level evidence supports primary shoulder stiffness treatment from conservative physiotherapy through surgical intervention; consensus guidelines enable evidence-based clinical practice.
Ankle Joint Microinstability: You Might Have Never Seen It but It Has Definitely Seen You.
Ankle microinstability from anterior talofibular ligament injury causes chronic pain requiring conservative treatment initially; arthroscopic repair recommended when conservative care fails.
A Scientometric Analysis of Studies on Patellar Dislocation.
Scientometric analysis identifies medial patellofemoral ligament reconstruction, risk factors, and pediatric cases as major research themes in patellar dislocation literature.
An international Delphi consensus outlines indications for revision surgery, return-to-play criteria, and follow-up standards for anterior shoulder instability, emphasizing bone loss, cuff integrity, and psychological readiness.
Degenerative Meniscus Lesions: An Expert Consensus Statement Using the Modified Delphi Technique.
Expert consensus confirms degenerative meniscus tears are normal aging; repairable tears should be repaired with conservative initial treatment.
