Bilateral Knee Arthroplasty in Patients Affected by Windswept Deformity: A Systematic Review.

Background: "Windswept" deformity (WSD) consists of a non-frequent condition in which the patient presents a valgus deformity in one knee and a varus deformity in the other. We performed a review of the available literature to aggregate the accessible data on the outcomes of bilateral knee arthroplasty in patients with WSD and to discuss the surgical challenges that this condition might pose.

Methods: A systematic review of the literature following the PRISMA guidelines was conducted.

Lateral unicompartmental knee arthroplasty (UKA) showed a lower risk of failure compared to medial unicompartmental knee arthroplasty in the Register of Prosthetic Orthopedic Implants (RIPO).

Introduction: The present study aimed to investigate differences in survivorship between medial and lateral unicompartmental knee arthroplasty (UKA) by analyzing the data of an Italian regional registry. The hypothesis was that, according to recent literature, lateral implants have comparable survivorship with regard to the medial implants.

Materials And Methods: The Register of Orthopaedic Prosthetic Implants (RIPO) of Emilia-Romagna (Italy) database was searched for all UKAs between July 1, 2000, and December 31, 2019.

Analysis of different geometrical features to achieve close-to-bone stiffness material properties in medical device: A feasibility numerical study.

Background And Objective: In orthopedic medical devices, elasto-plastic behavior differences between bone and metallic materials could lead to mechanical issues at the bone-implant interface, as stress shielding. Those issue are mainly related to knee and hip arthroplasty, and they could be responsible for implant failure. To reduce mismatching-related adverse events between bone and prosthesis mechanical properties, modifying the implant's internal geometry varying the bulk stiffness and density could be the right approach.

Does Implant Design Influence Failure Rate of Lateral Unicompartmental Knee Arthroplasty? A Meta-Analysis.

Background: Lateral unicompartmental knee arthroplasty (UKA) is a viable solution for isolated lateral compartment arthritis. Several prosthetic designs are available such as fixed-bearing metal-backed (FB M-B), fixed-bearing all-polyethylene (FB A-P), and mobile-bearing metal-backed (MB M-B) implants. The purpose of this meta-analysis is to compare failure rates of different prosthetic designs.

Lateral Closing Wedge High Tibial Osteotomy for Medial Compartment Arthrosis or Overload.

Lateral closing wedge osteotomies are still actual treatments of unicompartmental arthrosis and deformities. This article focuses on surgical timing, indications, and technique to achieve a pain-free knee joint and a normal weight forces distribution.

Diagnosis and Treatment of Infected Shoulder Arthroplasty: Current Concepts Review.

Periprosthetic shoulder infection (PSI) is an emerging pathology which requires many improvements in diagnosis and treatment to obtain a satisfying success rate. Different approaches have been described. This article summarizes current concepts of diagnostic process and main treatments described in the literature.
