Biomechanical evaluation of distal biceps tendon repair using tension slide technique and knotless fixation technique.

Background: Acute distal biceps tendon ruptures are uncommon injuries that often affect young active males, typically resulting from an eccentric load on their dominant extremity. The purpose of this study was to compare pullout strength and tendon gapping in the tension slide technique (TST) versus a knotless fixation technique (KFT).

Methods: Two sets of experiments were performed using cadaveric elbow specimens.

Anterior Cruciate Ligament Reconstruction With Bone-Patellar Tendon-Bone Autograft and a Medial Parapatellar Portal.

Anterior cruciate ligament (ACL) reconstruction is one of the most extensively studied surgical procedures in orthopaedics. The importance of this ligament for knee function and stability has been widely studied. For athletes who participate in activities involving cutting, twisting, and running, surgical reconstruction of the ACL has become the standard of care.

Patellar Tendinopathy.

Context: Patellar tendinopathy is a common condition. There are a wide variety of treatment options available, the majority of which are nonoperative. No consensus exists on the optimal method of treatment.

Bioabsorbable interference screw failure in anterior cruciate ligament reconstruction: A case series and review of the literature.

Background: To report a case series of failures of bioabsorbable interference screws with possible identification of a novel failure mechanism.

Methods: A retrospective review of ACL reconstructions by the senior author utilizing BioComposite™ Interference Screws (Arthrex, Inc., Naples, FL) was performed.

Repair techniques for acute distal biceps tendon ruptures: a systematic review.

Background: There is a lack of consensus regarding the optimal surgical approach and fixation method for distal biceps tendon ruptures. The purpose of this study was to conduct a systematic review comparing the results of the various surgical approaches and repair techniques for acute distal biceps tendon ruptures.

Methods: We searched the MEDLINE, Cochrane, and Embase databases for all published randomized controlled trials, prospective cohort studies, or case series that involved primary repairs of acute distal biceps tendon ruptures with use of a cortical button, intraosseous screws, suture anchors, or bone tunnels for fixation.

Effect of lower extremity fasciotomy length on intracompartmental pressure in an animal model of compartment syndrome: the importance of achieving a minimum of 90% fascial release.

Background: There has been an increase in minimally invasive surgery for chronic exertional compartment syndrome (CECS), despite the potential for incomplete compartment release and iatrogenic injuries. To our knowledge, no study has examined the effect of the length of fascial release on compartment pressures.

Purpose/hypothesis: The purpose was to explain the high failure rate seen in fascial release for CECS by evaluating the effect of fasciotomy length on intracompartmental pressures.

Physical examination of the patellofemoral joint.

Examination of the patellofemoral joint can prove to be challenging. Although certain acute injuries such as patella fracture or tendon rupture can be diagnosed quickly, more chronic injuries such as patellar subluxation and patellofemoral pain syndrome are more difficult to diagnose because of the subtlety of the examination findings. The source of the problem can also vary, and must be identified to direct treatment.

Iatrogenic injury of the anterior meniscal root attachments following anterior cruciate ligament reconstruction tunnel reaming.

Purpose: To determine whether reaming of anterior cruciate ligament (ACL) reconstruction tibial tunnels with a 10-mm-diameter reamer would result in injury to the anterior roots of the medial and lateral menisci in an in vitro model when using a tibial aiming device at two settings (40° and 60°).

Methods: Three-dimensional footprints of the ACL and the anterior roots of the menisci were measured for 12 human cadaveric tibias. Measurements were taken before and after attempted reaming of an ACL tibial reconstruction tunnel in the calculated ACL centre using a tibial aiming device set at two angles (40° and 60°).

Variability in locations of hip neurovascular structures and their proximity to hip arthroscopic portals.

Purpose: To measure the distances of pertinent neurovascular structures from bony landmarks used during hip arthroscopy and compare them among different demographic groups.

Methods: The distances from neurovascular structures to bony landmarks often used during hip arthroscopy were measured on magnetic resonance images of the hip in 100 patients. The structures studied include the lateral femoral cutaneous nerve (LFCN), sciatic nerve, femoral nerve, and femoral artery.

A systematic review of ulnar collateral ligament reconstruction techniques.

Background: Ulnar collateral ligament (UCL) reconstruction of the elbow has become increasingly more frequent among elite overhead athletes. The purpose of this study was to conduct a systematic review comparing the clinical outcomes and biomechanical results of the Jobe, modified Jobe, docking, modified docking, Endobutton, and interference screw techniques for UCL reconstruction.

Hypothesis: The docking technique will have significantly fewer complications and improved return-to-play rate.
