A Rare Case of Ruptured Appendicitis Secondary to Metastatic Ovarian Cancer.

BACKGROUND Patients with advanced stage ovarian cancer typically have vague non-specific abdominal symptoms related to pelvic tumor, metastasis, and ascites. When these patients present with more acute abdominal pain, appendicitis is rarely considered. Acute appendicitis due to metastatic ovarian cancer has been sparsely documented in the medical literature; only twice, to our knowledge.

Risk Factors for Repeat Debridement, Spacer Retention, Amputation, Arthrodesis, and Mortality After Removal of an Infected Total Knee Arthroplasty With Spacer Placement.

Background: Chronic periprosthetic joint infection (PJI) after total knee arthroplasty (TKA) is most commonly addressed with a 2-stage exchange procedure. The purpose of this study is to examine the natural history of patients who have undergone prosthesis removal and spacer placement and evaluate risk factors for outcomes other than reimplantation.

Methods: Patients who underwent removal of an infected TKA and placement of an antibiotic spacer for PJI were identified in a Medicare database.

Narcotic Use and Total Knee Arthroplasty.

Background: Although the United States is in the midst of a narcotic epidemic, risk factors for use and the impact of perioperative narcotic use on total knee arthroplasty (TKA) outcomes is ill-defined.

Methods: A national database was queried for patients who underwent primary TKA from 2007 to 2015. Patients taking narcotics in the preoperative, and for a prolonged period of time postoperatively, were identified.
