Consequences for preoperative pain and function when postponing elective knee and hip arthroplasty.

Introduction: The coronavirus outbreak causes postponement of elective surgery. We evaluated how pain, function and general health were impacted by postponing elective knee and hip arthroplasty in patients with knee and hip osteoarthritis with no known surgery rescheduling date due to the coronavirus outbreak.

Methods: This study included 194 patients from a Danish public hospital with postponed elective primary knee or hip arthroplasty due to the lockdown.

White blood cell scintigraphy for differentiation of infection and aseptic loosening: a retrospective study of 76 painful hip prostheses.

Background: Diagnosis of an infected arthroplasty is often difficult. Fever, abnormal physical findings, radiographic changes, findings at bone scintigraphy, an elevated erythrocyte sedimentation rate, CRP, and leucocytosis are not specific enough. We evaluated the diagnostic value of white blood cell scintigraphy.
