Intraoperative Acoustics: Auditory Cues in Hip Reconstructive Surgery.

Background: Orthopaedic surgeons rely on visual and tactile cues to guide performance in the operating room (OR). However, there is very little data on how sound changes during orthopaedic procedures and how surgeons incorporate audio feedback to guide performance. This study attempts to define meaningful changes in sound during vital aspects of total hip arthroplasty (THA) within the spectrum of human hearing.

A Consistent Anatomic Landmark for Identifying the Lateral Femoral Circumflex Artery in a Direct Anterior Hip Approach.

A direct anterior approach (DAA) is a technique practiced by arthroplasty surgeons that can be technically challenging, most notably for inexperienced surgeons. The lateral femoral circumflex artery (LFCA) is a branch of the femoral artery that crosses the surgical field during DAA and is an important landmark for superficial surgical dissection. If the vessel is not identified, significant bleeding may occur, and visualization may be impaired.

Socioeconomic Status Is Associated with Risk of Above-knee Amputation After Periprosthetic Joint Infection of the Knee.

Background: Above-knee amputation (AKA) is a severe but rare complication of TKA. Recent evidence suggests there are sex and racial disparities with regard to AKA after TKA. However, whether lower socioeconomic status is associated with an increased risk of AKA after TKA has not been conclusively established.

Cementless femoral fixation in total hip arthroplasty.

A number of cementless femoral stems are associated with excellent long-term survivorship. Cementless designs differ from one another in terms of geometry and the means of obtaining initial fixation. Strict classification of stem designs is important in order to compare results among series.

Knee arthrotomy repair with a continuous barbed suture: a biomechanical study.

We compared knee arthrotomy closures using interrupted biodegradable sutures and running bidirectionally barbed sutures in cadaveric specimens subjected to cyclic loading. During the initial 2000 flexion cycles, both groups maintained closure and no suture ruptured. Suture throws were then sequentially cut to weaken the repairs, and the knees were cyclically flexed after each cut.

Chronic expanding hematoma of the lateral thigh and massive bony destruction after a failed total hip arthroplasty.

Pseudotumors have been described around both stable and failed total hip arthroplasties. The causes are varied and include polyethylene debris and masses associated with metal-on-metal bearings. We present a patient with a massive tumor of the thigh that grossly and pathologically was associated with recurrent bleeding and extensive bony destruction.
