Evaluating two implant designs in patients undergoing primary total knee arthroplasty using a novel measure of early optimal recovery: a retrospective observational study.

Purpose: Quality of care in total knee arthroplasty (TKA) between implants was assessed using a novel composite outcome measure, early optimal recovery (EOR), to indicate ideal clinical outcomes and minimal healthcare resource utilization.

Methods: Patients that underwent primary TKA in the study group (ATTUNE® Knee System) or control group (LCS® COMPLETE Knee System) were included in this retrospective, single-center study. EOR was defined as no complications, no readmissions, no extra outpatient visits, ≤ 48 h length of hospital stay (LOS), and restored range of motion and pain perception at 3-month follow-up.

A Technique for Arthroscopic Osteochondral Autograft Transplantation of the Hip.

Osteochondritis dissecans of the hip is a rare condition with limited treatment options. For patients who have undergone arthroscopic microfracture and chondroplasty, long-term results showing clinical improvement are scarce. Although open osteochondral grafting is a demanding and invasive procedure, promising results are reported after short-term follow-up.

Knee upside down.

We present a case of a 19-year-old woman with a forced hyperextension trauma of the knee causing a posteromedial fracture, a medial meniscus root tear and rupture of the posterior cruciate ligament. The posteromedial fracture of the tibial plateau was treated operatively with open reduction and internal fixation. Anatomical reconstruction was achieved.

What is the Accuracy of Nuclear Imaging in the Assessment of Periprosthetic Knee Infection? A Meta-analysis.

Background: In the assessment of possible periprosthetic knee infection, various imaging modalities are used without consensus regarding the most accurate technique.

Questions/purposes: To perform a meta-analysis to compare the accuracy of various applied imaging modalities in the assessment of periprosthetic knee infection.

Methods: A systematic review and meta-analysis was conducted with a comprehensive search of MEDLINE and Embase in accordance with the PRISMA and Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) recommendations to identify clinical studies in which periprosthetic knee infection was investigated with different imaging modalities.
