Clinical and Radiographic Outcomes After Fixation of Chondral Fragments of the Knee in 6 Adolescents Using Autologous Bone Pegs.

Background: Little is known regarding the optimal treatment for displaced, purely chondral fragments in the knee.

Purpose: To report the clinical and radiographic outcomes of chondral fragment fixation in adolescents through use of autologous bone pegs.

Study Design: Case series; Level of evidence, 4.

Inferior graft maturity in the PL bundle after autograft hamstring double-bundle ACL reconstruction.

Purpose: The purpose of this study was to evaluate the signal/noise quotient (SNQ) for graft maturation and the serial changes observed in the magnetic resonance imaging (MRI) findings after double-bundle (DB) anterior cruciate ligament (ACL) reconstruction using a hamstring tendon autograft at a minimum of 5 years after surgery.

Methods: Forty-five patients who underwent DB ACL reconstruction between 2007 and 2010 were included in this prospective study. All participants underwent postoperative MRI at 3 weeks and 3, 6, 9 and 12, 18, 24, 36, 48 and 50 months.

Differences in levels of inflammatory mediators in meniscal and synovial tissue of patients with meniscal lesions.

Background: Meniscal injuries are a risk factor for osteoarthritis (OA). While a mechanical pathway between meniscal injury and OA has been described, the biological effects of inflammation on this pathway have yet to be clarified. The aim of our study was to compare levels of specific inflammatory mediators, tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and nerve growth factor (NGF), in injured and uninjured meniscal tissue and related knee joint synovium.

Arthroscopic osseous Bankart repair for chronic recurrent traumatic anterior glenohumeral instability. Surgical technique.

Background: A chronic osseous Bankart lesion has traditionally been treated with soft-tissue repair and/or open bone-grafting for a large glenoid defect. We developed an arthroscopic method of osseous reconstruction of the glenoid without bone-grafting. The purpose of this study was to evaluate the postoperative outcomes of our technique for chronic recurrent traumatic anterior glenohumeral instability.
