In this review, we evaluate the modern indications, subjective outcome scores, and survivorship results of unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO) in the treatment of isolated medial compartment degeneration of the knee. In addition, in a thorough review of the literature, we evaluate global trends in the use of both methods. In our evaluation of articles, we note that inclusion criteria are relatively broader for UKA than for HTO, where age and body mass index should be considered before HTO surgery in order to optimize clinical outcome and survivorship results...

Hospital readmissions are costly for patients and institutions. We conducted a study to evaluate rates of readmission within 30 days after anatomical total shoulder arthroplasty (ATSA) and reverse total shoulder arthroplasty (RTSA) and to determine independent risk factors for readmission. We queried the National Surgical Quality Improvement Program database for ATSAs and RTSAs performed between 2011 and 2013 and found a combined total of 3501 cases and an overall readmission rate of 2.7%. Of the readmissions, 67% were for medical complications, and 33% were for surgical complications...

Intramedullary tibial fixation is a commonly used and highly successfully treatment in acute fractures, nonunion settings, and correctional procedures. In the setting of a nonunion, removal of a failed implant can add to operative time and surgeon frustration while further compromising bone in an area already at risk for failure. Here we present a technique, using readily accessible equipment, for removing a distal solid tibial nail fragment in a manner that preserves bone.

Trunnionosis and taper corrosion have recently emerged as problems in total hip arthroplasty (THA). No longer restricted to metal-on-metal bearings, these phenomena now affect an increasing number of metal-on-polyethylene THAs and are exacerbated by modularity. Resulting increases in metal toxicity and patient morbidity, and the added costs of toxicity surveillance and revision surgery, will place a substantial economic burden on many health systems. Although they are more expensive than cobalt-chrome heads, ceramic femoral heads make metal toxicity a nonissue...

We conducted a study to compare 90-day outcomes of patients who underwent simultaneous bilateral total hip arthroplasties (THAs) through the direct anterior (DA) approach (n = 19 patients) or the posterior approach (n = 21) over a 2-year period (2012-2014). Compared with patients in the posterior group, patients in the DA group had longer operative times (153 vs 106 min; P < .001) and longer anesthesia times (257 vs 221 min; P = .007) but were more likely to be discharged home (100.0% vs 71.4%; P = .02)...

Reported rates of venous thromboembolism (VTE) after shoulder arthroplasty (SA) range from 0.2% to 13%. Few studies have evaluated the incidence of VTE in a large patient population from a single institution. We conducted a study to determine the incidence of VTE (deep venous thrombosis [DVT] and pulmonary embolism [PE]) in a large series of SAs. Cases of SAs performed at our institution between January 1999 and May 2012 were retrospectively reviewed for development of symptomatic VTE within the first 90 days after surgery...

Commonly accepted dogma is that patients with a long bone fracture due to a penetrating injury (gunshot wound) are less likely to follow up than blunt trauma patients. An institutional trauma database from a Level 1 academic trauma center was utilized to include all patients with long bone fractures from penetrating trauma from 2006-2009 (N = 132). Demographically matched blunt trauma patients with long bone fractures were included as a comparison group (N = 104). The medical records of these 236 patients were reviewed to observe their follow-up at 3, 6, 9, and 12 months...

Orthopedic surgery lacks racial and sexual diversity, which we hypothesized stems from absence of exposure to orthopedics during medical school. We conducted a study to determine whether diversity of matched orthopedic surgery residency applicants increased after introduction of a required third-year rotation. We compared 2 groups: precurriculum and postcurriculum. The postcurriculum group was exposed to a required 1-month musculoskeletal rotation during the third year of medical school. Comparisons were made of percentage of total students exposed to orthopedics, percentage who applied to and matched to orthopedic surgery, and proportion of women and underrepresented minorities...

Accelerated physical therapy (PT) protocols are a potential mechanism for achieving early mobilization and safe discharge from hospital after elective primary total hip arthroplasty (THA) or total knee arthroplasty (TKA). We compared 2 groups of patients who underwent elective unilateral THA or TKA-those who started PT the same day (Day 0) and those who started PT the next day (Non-Day 0). The difference in mean (SD) hospital length of stay between the Day 0 and Non-Day 0 groups was not statistically significant for THA patients, 2...

Aneurysmal bone cysts are uncommon primary bone tumors typically regarded as histologically and clinically benign. Malignant transformation of these lesions occurs almost exclusively in the context of prior radiation exposure. However, 4 cases of an osteosarcoma developing without prior radiation exposure have been reported. In this article, we report a fifth case of degeneration of an aneurysmal bone cyst to a fibroblastic osteosarcoma. In addition to reviewing the earlier cases, we describe the radiologic, pathologic, and immunohistochemical basis of this diagnosis...

Septic arthritis of the shoulder girdle remains relatively uncommon, with Staphylococcus aureus and β-hemolytic streptococci the typical offending organisms in adult patients. Rare cases of Streptococcus viridans, an oral bacterium with low virulence, have been reported in the setting of septic arthritis, mostly involving the knee joint or the sternoclavicular joint. In this article, we report a case of Streptococcus mitis infection of the glenohumeral joint that likely resulted from hematogenous spread after oral trauma in a patient with poor underlying dentition...

Inferior dislocation (luxatio erecta) is the most uncommon form of dislocation of the glenohumeral joint. The chance that a person endures the specific direction of forces to dislocate both shoulders simultaneously makes bilateral luxatio erecta even more uncommon. In this article, we report the case of a man who sustained bilateral luxatio erecta when he jumped from a falling scaffold and tried grabbing onto another structure.

We conducted a study to identify and contrast patterns in the treatment of common injuries that occur in National Football League (NFL) players and National Collegiate Athletic Association (NCAA) Division I football players. Orthopedic team physicians for all 32 NFL and 119 NCAA Division I football teams were asked to complete a survey regarding demographics and preferred treatment of a variety of injuries encountered in football players. Responses were received from 31 (97%) of the 32 NFL and 111 (93%) of the 119 NCAA team physicians...

Quadriceps and hamstring injuries occur frequently in football and are generally treated conservatively. While return to competition following hamstring strains is relatively quick, a high rate of injury recurrence highlights the importance of targeted rehabilitation and conditioning. This review describes the clinical manifestations of thigh-related soft-tissue injuries seen in football players. Two of these-muscle strains and contusions-are relatively common, while a third condition-the Morel-Lavallée lesion-is a rare, yet relevant injury...

Total knee arthroplasty (TKA) has evolved into a very successful procedure to relieve pain and improve function in the patient with advanced arthritis. Both short- and long-term outcomes are dependent on optimal surgical technique. In this article, I share a few of the many lessons learned over more than 40 years of experience performing TKA regarding exposure, alignment, bone preparation, correction of deformity, and prosthetic implantation.

Providing care to football players often involves recognizing and treating nonorthopedic conditions. We report on common ophthalmologic, dental, and dermatologic conditions seen by the football team physician.

Football has the highest injury rate amongst popular American sports. Of those injuries that end seasons or careers, the knee is the most common culprit. This is of particular concern because knee injuries are most common in football. This article reviews 4 of the most common knee injuries in American football, with emphasis on epidemiology, risk factors, and treatment outcomes. The injuries reviewed are tears of the anterior cruciate ligament, medial collateral ligament, medial patellofemoral ligament, and posterior cruciate ligament...
