Inter-surgeon variability in the identification of clock face landmarks when placing suture anchors in arthroscopic Bankart repair.

Background: The accuracy of surgeons in utilizing the clock face method for anchor placement has never been investigated. Our hypothesis was that shoulder arthroscopy surgeons would be able to place suture anchors at predetermined positions with accuracy and reliability.

Methods: Ten cadaveric shoulders were used.

Bone Marrow Mesenchymal Stromal Cell Treatment in Patients with Osteoarthritis Results in Overall Improvement in Pain and Symptoms and Reduces Synovial Inflammation.

Patients with late-stage Kellgren-Lawrence knee osteoarthritis received a single intra-articular injection of 1, 10, or 50 million bone marrow mesenchymal stromal cells (BM-MSCs) in a phase I/IIa trial to assess safety and efficacy using a broad toolset of analytical methods. Besides safety, outcomes included patient-reported outcome measures (PROMs): Knee Injury and Osteoarthritis Outcome Score (KOOS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC); contrast-enhanced magnetic resonance imaging (MRI) for cartilage morphology (Whole Organ MRI Scores [WORMS]), collagen content (T2 scores), and synovitis; and inflammation and cartilage turnover biomarkers, all over 12 months. BM-MSCs were characterized by a panel of anti-inflammatory markers to predict clinical efficacy.

IV and Perineural Dexmedetomidine Similarly Prolong the Duration of Analgesia after Interscalene Brachial Plexus Block: A Randomized, Three-arm, Triple-masked, Placebo-controlled Trial.

Background: Perineural and IV dexmedetomidine have each been suggested to prolong the duration of analgesia when administered in conjunction with peripheral nerve blocks. In the first randomized, triple-masked, placebo-controlled trial to date, the authors aimed to define and compare the efficacy of perineural and IV dexmedetomidine in prolonging the analgesic duration of single-injection interscalene brachial plexus block (ISB) for outpatient shoulder surgery.

Methods: Ninety-nine patients were randomized to receive ISB using 15 ml ropivacaine, 0.

A Qualitative Investigation of Return to Sport After Arthroscopic Bankart Repair: Beyond Stability.

Background: Arthroscopic shoulder stabilization is known to have excellent functional results, but many patients do not return to their preinjury level of sport, with return to play rates reported between 48% and 100% despite good outcome scores.

Purpose: To understand specific subjective psychosocial factors influencing a patient's decision to return to sport after arthroscopic shoulder stabilization.

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

Current concepts: the role of mesenchymal stem cells in the management of knee osteoarthritis.

Context: The number of adults with osteoarthritis in the United States is expected to nearly double from 21.4 million in 2005 to 41.1 million by 2030.

Trans-subscapularis portal versus low-anterior portal for low anchor placement on the inferior glenoid fossa: a cadaveric shoulder study with computed tomographic analysis.

Purpose: The purpose of this study was to evaluate the accuracy of inserting a glenoid anchor at the 5:30 clockface position using a trans-subscapularis (TSS) portal versus a low anterior (LA) portal.

Methods: Five surgeons (T.D.

The epidemiology of revision anterior cruciate ligament reconstruction in Ontario, Canada.

Background: Knowledge of the rate of and risk factors for re-revision, reoperation, and readmission after revision anterior cruciate ligament reconstruction (ACLR) is limited.

Purpose: To determine the rate of and risk factors for re-revision, reoperation, and readmission after revision ACLR.

Study Design: Descriptive epidemiology study.

Short- to Medium-term Outcomes After a Modified Broström Repair for Lateral Ankle Instability With Immediate Postoperative Weightbearing.

Background: Anatomic techniques of ankle ligament repair have the advantage of restoring the anatomy and kinematics of the joint. This study presents a technique for anatomic reconstruction of the lateral ligament complex by way of lateral ligament advancement using suture anchors associated with immediate protected full weightbearing; 2- to 5-year clinical outcomes are reported.

Hypothesis: This technique of providing an anatomic reconstruction with a secure fixation will enable early rehabilitation with immediate, protected weightbearing, with favorable outcomes.

The sizing of hamstring grafts for anterior cruciate reconstruction: intra- and inter-observer reliability.

Purpose: The objective of this study was to establish the intra- and inter-observer reliability of hamstring graft measurement using cylindrical sizing tubes.

Methods: Hamstring tendons (gracilis and semitendinosus) were harvested from ten cadavers by a single surgeon and whip stitched together to create ten 4-strand hamstring grafts. Ten sports medicine surgeons and fellows sized each graft independently using either hollow cylindrical sizers or block sizers in 0.

A rare cause of foot pain with golf swing: symptomatic os vesalianum pedis-a case report.

The os vesalianum is an uncommon accessory bone of the foot, located proximally to the base of the fifth metatarsal. It is usually asymptomatic and detected incidentally on radiographs. This is a case of bilateral os vesalianum, symptomatic only in the right foot, in a golf player.

A qualitative investigation of the decision to return to sport after anterior cruciate ligament reconstruction: to play or not to play.

Background: Primary anterior cruciate ligament (ACL) reconstruction is known to have excellent outcomes, but many patients do not return to their preinjury level of sport participation. Previous studies have used subjective outcome scores to evaluate this discrepancy, but none to date has used qualitative, in-depth patient interviews.

Purpose: To understand the factors influencing a patient's decision to return to his or her preinjury level of sport after ACL reconstruction.
