Complications Associated With Medial Opening-Wedge High Tibial Osteotomy Using a Locking Plate: A Multicenter Study.

Background: The aim of this study is to investigate complications following medial opening-wedge high tibial osteotomy using a locking plate. In addition, we aimed to compare postoperative outcomes between the complicated and the uncomplicated group.

Methods: This study enrolled 209 patients who underwent medial opening-wedge high tibial osteotomy between 2010 and 2015.

The Learning Curve for Biplane Medial Open Wedge High Tibial Osteotomy in 100 Consecutive Cases Assessed Using the Cumulative Summation Method.

Purpose: The purpose of this study was to investigate whether surgical experience could improve surgical competency in medial open wedge high tibial osteotomy (MOWHTO).

Materials And Methods: One hundred consecutive cases of MOWHTO were performed with preoperative planning using the Miniaci method. Surgical errors were defined as under- or overcorrection, excessive posterior slope change, or the presence of a lateral hinge fracture.

Difference in the degree of improvement in patient-reported outcomes after total knee arthroplasty between octogenarians and sexagenarians: a propensity score matching analysis.

Background: As the population ages, the use of primary total knee arthroplasty (TKA) is on the rise in the octogenarian population.

Aims: The objective of this study was to compare patient-reported outcomes after TKA in octogenarians versus sexagenarians.

Methods: This retrospective case-controlled comparative study with a propensity score matching analysis was conducted by 251 patients who underwent TKA for degenerative osteoarthritis of the knee.
