Return to Play Following Meniscal Repair.

Meniscal injuries in athletes present a challenging problem. Surgeons must balance the needs of the healing meniscus with the desire of the athlete to return to play as quickly as possible. Evidence-based rehabilitation protocols are important for ensuring a successful meniscal repair and preventing athletes from returning to play prematurely.

Efficacy and Cost-effectiveness of Topical Vancomycin Powder in Primary Cementless Total Hip Arthroplasty.

Topical vancomycin has been shown to effectively reduce infections after spinal surgery while remaining safe and cost-effective; however, there are few studies evaluating topical vancomycin in total hip arthroplasty. The authors hypothesized that the incidence of periprosthetic joint infection would decrease with the use of topical vancomycin in total hip arthroplasty and that topical vancomycin would be cost-effective. A retrospective patient chart review was performed to evaluate consecutive primary cementless total hip arthroplasties performed in the authors' hospital system between April 2015 and December 2016.

Diagnosis and Management of Hip Abductor Insufficiency.

Greater Trochanteric Pain Syndrome (GTPS) is a common cause of lateral hip pain, with an incidence of 1.8 per 1000 patients, most commonly occurring between the fourth and sixth decades of life. When GTPS fails to improve with conservative management, hip abductor insufficiency should be suspected.

Diagnostic Criteria and Clinical Outcomes in Sarcopenia Research: A Literature Review.

By the sixth decade of life, nearly one quarter of the population has substantial muscle atrophy, or sarcopenia. Despite the creation of a standardized definition of sarcopenia by the European Working Group on Sarcopenia in Older People, variability may exist in the diagnostic criteria utilized for clinical sarcopenia research. The primary objectives of this review were to characterize diagnostic criteria used for measurement of sarcopenia in original studies, and to describe associations between sarcopenia and important clinical outcomes.

Inpatient costs and blood transfusion rates of sarcopenic patients following thoracolumbar spine surgery.

OBJECTIVE Sarcopenia, the muscle atrophy associated with aging and disease progression, accounts for nearly $18.5 billion in health care expenditures annually. Given the high prevalence of sarcopenia in patients undergoing orthopedic surgery, the goal of this study was to assess the impact of sarcopenia on inpatient costs following thoracolumbar spine surgery.

Technique Tip.

Unlabelled: Lisfranc injury fixation or arthrodesis typically involves the reduction and fixation of several tarsometatarsal joints with either screws or a plate and screw constructs. A successful fixation or arthrodesis of the Lisfranc joint requires proper screw placement from the medial cuneiform to the base of the second metatarsal. This is typically done free-hand; however, we describe use of an anterior cruciate ligament guide to help maintain reduction and assist with drill trajectory for more accurate screw or suture button construct placement.

Patient-Specific Orthopaedic Implants.

Patient-specific orthopaedic implants are emerging as a clinically promising treatment option for a growing number of conditions to better match an individual's anatomy. Patient-specific implant (PSI) technology aims to reduce overall procedural costs, minimize surgical time, and maximize patient outcomes by achieving better biomechanical implant fit. With this commercially-available technology, computed tomography or magnetic resonance images can be used in conjunction with specialized computer programs to create preoperative patient-specific surgical plans and to develop custom cutting guides from 3-D reconstructed images of patient anatomy.
