Background: Nosocomephobia, a type of posttraumatic stress disorder (PTSD), is a diagnosis of an extreme fear of hospitals that can hinder current/future medical care. There is little research on how nosocomephobia affects elective surgery or how acupuncture can help patients cope.
Methods: Using the transactional model of stress/coping, this qualitative case study examined the role of acupuncture in nosocomephobia patients' elective surgery appraisal processes.
Introduction: Instability after total knee arthroplasty (TKA) remains a leading cause of revision TKA and can lead to patient dissatisfaction. While many companies have developed midlevel constrained (MLC) polyethylene inserts in primary TKAs, there is little data on their outcomes.
Purpose: We sought to analyze short-term outcomes including survivorship, rates of manipulation under anesthesia (MUA), and improvements in patient-reported outcome measures (PROMs) preoperatively to postoperatively in one design of MLC TKA.
Medial unicompartmental knee arthroplasty (mUKA) is a highly effective treatment for the management of isolated osteoarthritis in the medial compartment. While favorable long-term survivorship is seen in most series, the long-term rate of revision after mUKAs remains higher than that for total knee arthroplasty. Poor indications and poor surgical technique are often responsible for mUKA failure.

- A systematic review was conducted to examine how patient characteristics in randomized controlled trials (RCTs) for revision total joint arthroplasty (rTJA) compare with those in the general US patient population undergoing similar procedures.
- The study analyzed 46 RCTs, finding that demographic factors such as age and BMI showed only small differences when compared to national patient cohorts from HCUP NIS and ACS-NSQIP.
- The findings suggest that the rTJA RCT patient population closely resembles the broader US demographic, with minimal differences that are unlikely to affect clinical outcomes.
Modern primary cementless total knee arthroplasty (TKA) is increasingly popular, but there is limited evidence on its benefits, early complications, and failures. : We sought to evaluate operative time, early survivorship, and outcomes of cementless versus cemented TKA of the same design. : As part of this single-center, multisurgeon, retrospective cohort study, we reviewed 598 primary, unilateral TKAs (170 cementless, 428 cemented) of the same design from 2016 to 2018.
