The importance of cost control in total knee arthroplasty is increasing in the United States secondary to both changing economic realities of healthcare and the increasing prevalence of joint replacement. Surgeons play a critical role in cost containment and may soon be incentivized to make cost-effective decisions under proposed gainsharing programs. The purpose of this study is to examine the cost-effectiveness of all-polyethylene tibial (APT) components and determine what difference in revision rate would make modular metal-backed tibial (MBT) implants a more cost-effective intervention...

It has been suggested that the utilization of joint arthroplasty in patients with rheumatoid arthritis (RA) is decreasing; however, this observation is largely based upon evidence pertaining to lower-extremity joint arthroplasty. It remains unknown if these observed trends also hold true for shoulder arthroplasty. The purpose of this study is to utilize a nationally representative population database in the US to identify trends in the utilization of shoulder arthroplasty among patients with RA. Secondarily, we sought to determine the rate of early adverse events, length of stay, and hospitalization costs associated with RA patients undergoing shoulder arthroplasty and to compare these outcomes to those of patients without a diagnosis of RA undergoing shoulder arthroplasty...

The purpose of this study is to describe the rate of return to the operating room (OR) following microfracture (MFX), autologous chondrocyte implantation (ACI), osteochondral autograft transplantation (OATS), and osteochondral allograft (OCA) procedures at 90 days, 1 year, and 2 years. Current Procedural Terminology codes for all patients undergoing MFX, ACI, OATS, and OCA were used to search a prospectively collected, commercially available private payer insurance company database from 2007 to 2011. Within 90 days, 1 year, and 2 years after surgery, the database was searched for the occurrence of these same patients undergoing knee diagnostic arthroscopy with biopsy, lysis of adhesions, synovectomy, arthroscopy for infection or lavage, arthroscopy for removal of loose bodies, chondroplasty, MFX, ACI, OATS, OCA, and/or knee arthroplasty...

Pain control following hip arthroscopy presents a significant clinical challenge, with postoperative pain requiring considerable opioid use. Peripheral nerve blocks (PNBs) have emerged as one option to improve pain and limit the consequences of opioid use. The purpose of this study is to provide a comprehensive review of outcomes associated with PNB in hip arthroscopy. We hypothesize that the use of PNB in hip arthroscopy leads to improved outcomes and is associated with few complications. A systematic review of PubMed, Medline, Scopus, and Embase databases was conducted through January 2015 for English-language articles reporting outcome data, with 2 reviewers independently reviewing studies for inclusion...

This study was performed to compare outcomes of open, arthroscopic, and percutaneous surgical techniques for lateral epicondylitis. We searched PubMed (MEDLINE) for literature published between January 1, 2004 and May 23, 2015 using these key words: lateral epicondylitis AND (surgery OR operative OR surgical OR open OR arthroscopic OR percutaneous). Meta-analyses were performed for outcomes reported in 3 studies using 2-sample and 2-proportion Z-tests. Thirty-five studies including 1640 elbows (1055 open, 401 arthroscopic, 184 percutaneous) met the inclusion criteria...

We evaluated postoperative pain control and narcotic usage after thumb carpometacarpal (CMC) arthroplasty or open reduction and internal fixation (ORIF) of the distal radius in patients given opiates with or without other non-opiate medication using a specific dosing regimen. A prospective, randomized study of 79 patients undergoing elective CMC arthroplasty or ORIF of the distal radius evaluated postoperative pain in the first 5 postoperative days. Patients were divided into 4 groups: Group 1, oxycodone and acetaminophen PRN; Group 2, oxycodone and acetaminophen with specific dosing; Group 3, oxycodone, acetaminophen, and OxyContin with specific dosing; and Group 4, oxycodone, acetaminophen, and ketorolac with specific dosing...

The articular surface replacement (ASR) monoblock metal-on-metal acetabular component was recalled due to a higher than expected early failure rate. We evaluated the survivorship of the device and variables that may be predictive of failure at a minimum of 5-year follow-up. A single-center, single-surgeon retrospective review was conducted in patients who received the DePuy Synthes ASR™ XL Acetabular hip system from December 2005 to November 2009. Mean values and percentages were calculated and compared using the Fisher's exact test, simple logistic regression, and Student's t-test...

Standard 2-dimensional (2-D) computed tomography (CT) scans of the shoulder are often aligned to the plane of the body as opposed to the plane of the scapula, which may challenge the ability to accurately measure glenoid width and glenoid bone loss (GBL). The purpose of this study is to determine the effect of sagittal rotation of the glenoid on axial anterior-posterior (AP) glenoid width measurements in the setting of anterior GBL. Forty-three CT scans from consecutive patients with anterior GBL (minimum 10%) were reformatted utilizing open-source DICOM software (OsiriX MD)...

Gustilo IIIB injuries of the tibia with segmental bone loss continue to be a difficult reconstructive problem. The serratus anterior-latissimus-rib (SALR) composite flap consists of bone and muscle; this flap can provide soft tissue coverage and vascularized bone in a single surgical procedure. The purpose of this study is to describe the use of the SALR flap for the treatment of a large open tibia fracture with segmental bone loss, with a specific focus on postoperative complications, limb salvage, and time to union...

Matthew P Noyes, Patrick J Denard
Postoperative pain management is an important component of total shoulder arthroplasty (TSA). Continuous cryotherapy (CC) has been proposed as a means of improving postoperative pain control. However, CC represents an increased cost not typically covered by insurance. The purpose of this study is to compare CC to plain ice (ICE) following TSA. The hypothesis was that CC would lead to lower pain scores and decreased narcotic usage during the first 2 weeks postoperatively. A randomized controlled trial was performed to compare CC to ICE...

#11
Florian M Kovar, Julio J Jauregui, John E Herzenberg
Fixator-assisted nailing (FAN) and fixator-assisted locked plating (FALP) are 2 techniques that can be used to correct distal femoral valgus deformities. The fixator aids in achieving an accurate adjustable initial reduction, which is then made permanent with either nail or plate insertion. FALP can be performed with the knee held in a neutral extended position, whereas FAN requires 30° to 90° of knee flexion to insert the nail, which may cause some alignment loss. We hypothesized that FAN may yield less accurate correction than FALP...

Robert Mason, Taylor Buckley, Richard Southgate, Gregg Nicandri, Richard Miller, Ilya Voloshin
Lesser tuberosity osteotomy (LTO) and subscapularis tenotomy (ST) are used for takedown of the subscapularis during shoulder arthroplasty. LTO offers the theoretical but unproven benefit of improved healing and function of the subscapularis. However, humeral stem subsidence and loosening may be greater when osteotomy is performed, which may compromise functional outcomes. Our hypothesis is that no difference in proximal collar press-fit humeral stem subsidence or loosening exists, with no impairment of functional outcomes using the LTO technique...

Diaphyseal fractures of the distal humerus have a high rate of union when treated with a functional brace or an above-elbow cast (AEC). This study compares alignment of the humerus and motion of the elbow after functional brace or AEC treatment. One-hundred and five consecutive patients with a closed, extra-articular fracture of the distal humeral diaphysis were identified in the orthopedic trauma databases of 3 hospitals between 2003 and 2012. Seventy-five patients with a follow-up of at least 6 months or with radiographic and clinical evidence of fracture union were included (51 treated with functional bracing and 24 treated with an AEC)...

Eitan Melamed, Charles P Melone
Soft tissue defects associated with exposed tendon pose difficult reconstructive problems because of tendon adhesions, poor range of motion, poor cosmetic appearance, and donor site morbidity. Dermal regeneration template is a skin substitute widely used in reconstructive surgery, including the occasional coverage of tendons. However, postoperative functionality of the tendons has not been well documented. We report a case of using dermal regeneration template for soft tissue reconstruction overlying tendons with loss of paratenon in a patient with Dupuytren's contracture...

The lateral tibial eminence shares a close relationship with the anterior root of the lateral meniscus. Limited studies have reported traumatic injury to the anterior meniscal roots in the setting of tibial eminence fractures, and reported rates of occurrence of concomitant meniscal and chondral injuries vary widely. The purpose of this article is to describe the case of a 28-year-old woman who had a complete avulsion of the anterolateral meniscal root caused by a tibial eminence fracture with resultant malunion and root displacement...

Both anatomical total shoulder arthroplasty (TSA) and reverse shoulder arthroplasty (RSA) are routinely performed for patients who desire to continuously work or participate in sports. This study analyzes and compares the ability of patients to work and partake in sports following shoulder arthroplasty based on responses to clinical outcome surveys. A retrospective review of the shoulder surgery repository was performed for all patients treated with TSA and RSA and who completed questions 9 and 10 on the activity patient self-evaluation portion of the American Shoulder and Elbow Surgeons (ASES) Assessment Form...

Gary M Kiebzak
Dual-energy X-ray absorptiometry (DXA) is a well-established technology with an important and well-known role in measuring bone mineral density (BMD) for the purpose of determining fracture risk, diagnosing osteoporosis, and monitoring treatment efficacy. However, aside from the assessment of bone status, DXA is likely underutilized in the field of orthopedics, and most orthopedists may not be aware of the full capabilities of DXA, particularly with regard to total body scans and body composition assessment...

A central distal femoral physeal bone bridge in a boy aged 5 years and 7 months was resected with a fluoroscopically guided core reamer placed through a lateral parapatellar approach. At 3-year follow-up, the boy's leg-length discrepancy was 3.0 cm (3.9 cm preoperatively), and the physeal bone bridge did not recur. The patient had full function and no pain or other patellofemoral complaints. This technique provided direct access to the physeal bone bridge, and complete resection was performed without injury to the adjacent physeal cartilage in the medial and lateral columns of the distal femur, which is expected to grow normally in the absence of the bridge...

Use of mesenchymal stem cells from bone marrow has gained significant popularity. The iliac crest has been determined to be an effective site for harvesting mesenchymal stem cells. Review of the literature reveals that multiple techniques are used to harvest bone marrow aspirate from the iliac crest, but the descriptions are based on the experience of various authors as opposed to studied anatomy. A safe, reliable, and reproducible method for aspiration has yet to be studied and described. We hypothesized that there would be an ideal angle and distance for aspiration that would be the safest, most consistent, and most reliable...
