New research released last week suggests that sex matters when it comes to surgery. Researchers examined the sex of the surgeon and the sex of the patient in over a million surgeries and found that female patients with male doctors fared slightly worse than any other combination. The reason for the disparity likely comes down to communication and relationship-building.

Osteochondral autograft transfer (OAT) restores hyaline cartilage and subchondral bone in a single stage, offering a durable joint-preserving option for focal full-thickness articular cartilage defects in young, active patients.

Biologic augmentation is increasingly used across knee-preservation procedures, but evidence remains fragmented by procedure and biologic type.

OATS is an effective single-stage, joint-preserving option for selected young patients with moderate-sized Grade IV knee osteochondral lesions, but longer-term studies are needed to confirm durability and superiority over other cartilage-restoration techniques.

We have presented two cases of large, isolated chondral defects of the medial femoral condyle treated with acellular collagen matrix.

To perform a systematic review evaluating the efficacy of orthobiologic injections as adjuncts to cartilage-preserving surgery in improving clinical, radiographic, and histologic outcomes in adults with focal knee cartilage defects.

Nanochon, a Baltimore-based medical device company, announced on September 2, 2026 that it successfully treated the first patient in the First-in-Human clinical study for Chondrograft™, its 3D-printed implant for knee cartilage repair.

Synovial sarcoma (SS) lacks effective therapies and physiologically relevant models that faithfully recapitulate the tumor microenvironment.

Re-excision for recurrent bone and soft tissue tumor involves increased surgical morbidity, often with significant bone and soft tissue loss associated with removal of indwelling implants.

Ewing sarcoma of the tibial shaft in a very young child presents a significant limb-salvage challenge. Treatment requires effective local control while preserving limb function and accommodating future growth.

Circulating tumor DNA (ctDNA) holds promise for prognostication and disease monitoring in solid tumors.
