Orthopaedic surgical procedures are increasingly being performed in outpatient settings. The drive for cost reduction without compromising patient safety and outcomes has increased interest in outpatient total shoulder arthroplasty (TSA). The primary aim of this study was to perform a review of the evidence regarding the outcomes and cost-effectiveness of outpatient TSA.

A search of the PubMed, Embase, and Cochrane Library databases was performed using several keywords “outpatient,” “shoulder replacement,” “ambulatory,” “day case,” “day-case,” “shoulder arthroplasty,” “same day,” and “shoulder surgery.” Studies that were published from May 2010 to May 2020 in the English language were considered. Research design, questions, and outcomes were recorded for each study. Qualitative and quantitative pooled analysis was performed on the data where appropriate.

Twenty studies met the inclusion criteria. Six retrospective studies compared complication rates between inpatient and outpatient cohorts and found no ent selection is the most critical factor that predicts the success of outpatient TSA. selleck products While outpatient TSA is significantly less costly than inpatient TSA, patients undergoing outpatient TSA are more likely to be healthier than patients undergoing inpatient TSA. More high-quality long-term studies are needed to add to this body of evidence.

We present a case of a 35-year-old-man with a giant sclerosing epithelioid fibrosarcoma (SEF) of the thigh. The patient presented with a history of a painful thigh mass. Plain radiographs revealed a soft-tissue mass with extensive calcifications, whereas on magnetic resonance imaging, a lobulated mass between the adductors and the posterior muscles of the thigh was noted. A wide en block resection was undertaken, and the histopathology confirmed the diagnosis of SEF. Postoperative radiation therapy was followed. The patient had no signs of recurrence at the 4-year follow-up.

The clinicopathological, imaging characteristics, and treatment options of this rare soft-tissue tumor are discussed.

Recently, there has been a resurgence of interest in primary anterior cruciate ligament (ACL) repair that has the potential to preserve native tissue using a more minimally invasive approach. Multiple repair techniques for different tear types have been reported over the last decade.

From a healing perspective, proximal tears can be reapproximated directly to the femoral wall because they have better intrinsic healing capacity than midsubstance tears. These procedures can be classified further as direct suture repair with or without static or dynamic augmentation. Current evidence does not support direct repair of midsubstance tears because of their limited healing capacity. In many instances, biological augmentation is needed to enhance the healing potential of the ACL.

While ACL repair is certainly not an effective surgical approach for all tears or in all patients, this procedure can be an effective and less morbid alternative to ACL reconstruction in carefully selected patients.

The overall current reported level of evidence of published studies has ranged from low to moderate, and thus there is a need for higher-quality, comparative studies in which outcomes of larger patient groups are compared with the current gold standard of ACL reconstruction.

A 34-year-old woman with developmental dysplasia of the hip (DDH) presented with chronic left hip pain related to a femoral head cyst. The patient strongly preferred a joint-preserving option. Periacetabular osteotomy (PAO) has shown reliable options for managing DDH, and femoral head fresh osteochondral allograft (FOCA) can be performed for cysts. We performed these procedures concomitantly for the first time. At 1-year follow-up, the patient had functional, pain-free motion and high satisfaction.

PAO and femoral head FOCA can be performed concomitantly with a common, anterior hip approach. They are a viable, joint-preserving option for patients with DDH and osteochondral lesions.

Chronic quadriceps tendon (QT) ruptures are uncommon injuries that present treatment challenges due to their complex nature and the limited evidence to guide management.

Timely diagnosis and surgical management of acute QT injury are imperative to optimize patient outcomes as delayed diagnosis leads to poorer results regardless of treatment modality.

Elements of chronic QT ruptures that may complicate surgical management include patient age, comorbidity, scar-tissue formation, amount of quadriceps muscle/ tendon retraction, and distalmigration of the patella with contraction of the tendon.

Treatment options for chronic QT ruptures include primary repair with or without vastus advancement, V-Y tendon lengthening with or without tissue augmentation, and autograft or allograft reconstruction.

We have previously shown that targeting smooth muscle integrin α5β1 interaction with fibronectin can mitigate the effects of airway hyperresponsiveness by impairing force transmission. In this study, we show that another member of the integrin superfamily, integrin α2β1, is present in airway smooth muscle and capable of regulating force transmission via cellular tethering to the matrix protein collagen I and, to a lesser degree, laminin-111. The addition of an inhibitor of integrin α2β1 impaired IL-13-enhanced contraction in mouse tracheal rings and human bronchial rings and abrogated the exaggerated bronchoconstriction induced by allergen sensitization and challenge. We confirmed that this effect was not due to alterations in classic intracellular myosin light chain phosphorylation regulating muscle shortening. Although IL-13 did not affect surface expression of α2β1, it did increase α2β1-mediated adhesion and the level of expression of an activation-specific epitope on the β1 subunit.
