Quadriceps tendon autograft for primary anterior cruciate ligament reconstruction show comparable clinical, functional, and patient-reported outcome measures, but lower donor-site morbidity compared with hamstring tendon autograft: A matched-pairs study with a mean follow-up of 6.5 ​years.

Objectives: To compare clinical and functional outcomes of patients after primary anterior cruciate ligament reconstruction (ACLR) using quadriceps tendon- (QT-A) and hamstring tendon (HT-A) autograft with a minimum follow-up (FU) of 5 years.

Methods: Between 2010 and 2014, all patients undergoing ACLR were recorded in a prospectively administered database. All patients with primary, isolated QT-A ACLR and without any concomitant injuries or high grade of osteoarthritis were extracted from the database and matched to patients treated with HT-A.

Watertightness of wound closure in lumbar spine-a comparison of different techniques.

Background: Since a primary watertight dural suture after incidental durotomies has a failure rate of 5-10%, a watertight closure technique of the overlying layers (fascia, subcutis and skin) is essential. The purpose of this cadaveric study was to find the most watertight closure technique for fascia, subcutis and skin.

Methods: Different suturing techniques were tested for each layer in a sheep cadaveric model by measuring the leakage pressure.

Salvage reverse total shoulder arthroplasty for failed operative treatment of proximal humeral fractures in patients younger than 60 years: long-term results.

Hypothesis: Is salvage reverse total shoulder arthroplasty (RTSA) a justifiable treatment for failed operative treatment (open reduction-internal fixation [ORIF] or primary and secondary hemiarthroplasty) of proximal humeral fractures in patients younger than 60 years?

Methods: Thirty patients (mean age, 52 years; age range, 30-59 years) were reviewed after a mean follow-up period of 11 years (range, 8-18 years). Of the patients, 7 (23%) underwent RTSA for failed ORIF and 23 (77%) for failed hemiarthroplasty. Clinical and radiographic outcomes were assessed longitudinally.

Reverse Total Shoulder Arthroplasty for Massive, Irreparable Rotator Cuff Tears Before the Age of 60 Years: Long-Term Results.

Background: There has been serious concern regarding the longevity and durability of outcomes of reverse total shoulder arthroplasty (RTSA) in younger patients. It was the purpose of this study to analyze long-term outcomes and complications of RTSA for irreparable rotator cuff tears in patients younger than 60 years.

Methods: Twenty patients (23 shoulders) with a mean age of 57 years (range, 47 to 59 years) were evaluated at a mean of 11.

MR findings associated with positive distraction of the hip joint achieved by axial traction.

Purpose: To determine which MR-arthrography findings are associated with positive hip joint distraction.

Materials And Methods: One hundred patients with MR arthrography of the hip using axial traction were included. Traction was applied during the MR examination with an 8 kg (females) or 10 kg (males) water bag, attached to the ankle over a deflection pulley.

Supraacetabular fossa (pseudodefect of acetabular cartilage): frequency at MR arthrography and comparison of findings at MR arthrography and arthroscopy.

Purpose: To evaluate the frequency of the supraacetabular fossa (SAF) (pseudodefect of acetabular cartilage) at magnetic resonance (MR) arthrography of the hip and to compare the MR findings with those from arthroscopy.

Materials And Methods: All patients gave written permission for anonymized use of their medical data for scientific purposes before the imaging examination. The study was submitted to the institutional review board, and the need to obtain additional approval was waived.
