The Chitranjan Ranawat Award: Running Subcuticular Closure Enables the Most Robust Perfusion After TKA: A Randomized Clinical Trial
Maintaining robust perfusion is an important physiologic parameter in wound healing. The effect of different closure techniques on wound perfusion after total knee arthroplasty (TKA) has not been established previously and may have implications for wound healing.
What Is the Relationship Between Depressive Symptoms and Pain During Functional Tasks in Persons Undergoing TKA? A 6-year Perioperative Cohort Study
Preoperative depressive symptoms have been shown in some but not all studies to be associated with poor self-reported pain and function outcomes. In addition, depressive symptoms after surgery have been shown to improve relative to preoperative levels.
Is Neuraxial Anesthesia Safe in Patients Undergoing Surgery for Treatment of Periprosthetic Joint Infection?
There is concern that neuraxial anesthesia in patients undergoing surgery for treatment of a periprosthetic joint infection (PJI) may increase the risk of having a central nervous system infection develop. However, the available data on this topic are limited and contradictory.
Increased contact stresses after meniscectomy have led to an increased focus on meniscal preservation strategies to prevent articular cartilage degeneration. Platelet-rich plasma (PRP) has received attention as a promising strategy to help induce healing and has been shown to do so both in vitro and in vivo. Although PRP has been used in clinical practice for some time, to date, few clinical studies support its use in meniscal repair.
Is There an Advantage to Knotless Barbed Suture in TKA Wound Closure? A Randomized Trial in Simultaneous Bilateral TKAs
Effective wound closure is critical to minimizing wound complications and withstanding the forces associated with early knee motion after TKA. Barbed sutures allow for knotless fixation, have been used successfully in other specialties, and may provide for more even distribution of tension along the length of the incision; however, data regarding unidirectional barbed sutures from randomized trials have raised important concerns about their use. Bidirectional barbed sutures offer a potential alternative, but have not been studied extensively in orthopaedic surgery.
Articular cartilage has minimal endogenous ability to undergo repair. Multiple chondral restoration strategies have been attempted with varied results.
Lateral Opening-wedge Distal Femoral Osteotomy: Pain Relief, Functional Improvement, and Survivorship at 5 Years
Distal femoral varus osteotomy may be used to treat valgus knee malalignment or to protect a knee compartment in which cartilage restoration surgery (such as osteochondral or meniscus allografting) has been performed. Medial closing-wedge osteotomy has demonstrated good success in treatment of osteoarthritis in published series, but few studies have evaluated distal femoral lateral opening-wedge osteotomy in terms of correction of deformity, pain and function, and survivorship.
Restoration of posterior condylar offset during TKA is believed to be important to improving knee kinematics, maximizing ROM, and minimizing flexion instability. However, controversy exists regarding whether there are important anatomic differences between sexes and whether a unisex knee prosthesis can restore the anatomy of knees in males and females.
Do Glycemic Markers Predict Occurrence of Complications After Total Knee Arthroplasty in Patients With Diabetes?
Patients with diabetes have increased risk of infections and wound complications after total knee arthroplasty (TKA). Glycemic markers identifying patients at risk for complications after TKA have not yet been elucidated.
Is There a Difference in Total Knee Arthroplasty Risk of Revision in Highly Crosslinked versus Conventional Polyethylene?
Highly crosslinked polyethylene (HXLPE) was introduced to reduce wear and associated osteolysis in total knee arthroplasty (TKA). However, there is limited clinical evidence that HXLPE is more effective than conventional polyethylene (CPE) in TKA.
