Postoperative improvement in patient-reported outcomes after neutral alignment medial open wedge high tibial osteotomy for medial compartment knee osteoarthritis in patients aged ≥70 years versus younger patients.

Purpose: To compare the postoperative clinical and radiological outcomes in patients aged ≥70 years following neutral alignment medial opening-wedge high tibial osteotomy (NA-MOWHTO) for medial compartment knee osteoarthritis (KOA) to those observed in younger patients.

Methods: The data of patients who underwent NA-MOWHTO for medial compartment KOA between September 2018 and June 2022 were retrospectively analysed. The patients were categorised into groups Y (<70 years) and O (≥70 years).

Valgus knee deformity due to nonunion of lateral Hoffa fracture: A case report.

Hoffa fractures are rare intra-articular injuries, and nonunion of Hoffa fractures is rarer. We report the case of an adult male with a nonunion of a Hoffa fracture by open reduction and internal fixation in which the lateral meniscus tear was treated by an arthroscopic surgery. A healthy 38-year-old man who had a history of untreated trauma to the left knee in a motorcycle accident 11 years ago presented to our hospital with the complaint of chronic left knee pain for 5 years.

Younger age is a significant factor for poorer adherence in fracture patients who received low-intensity pulsed ultrasound: A retrospective study.

Background: The factors for poor adherence to therapy in patients with postoperative fracture who are treated with low-intensity pulsed ultrasound remain unknown. Therefore, we designed a retrospective cohort study to determine the various factors for poorer adherence to therapy in patients with postoperative fracture who were treated with low-intensity pulsed ultrasound therapy.

Methods: We retrospectively analyzed the data of postoperative patients who underwent low-intensity pulsed ultrasound after fracture surgery from January 2010 to May 2019.

Addition of 3D-CT evaluation to radiographic images and effect on diagnostic reliability of current 2018 AO/OTA classification of femoral trochanteric fractures.

Introduction: The AO/OTA classification for diagnosing femoral trochanteric fractures (31A fractures) was revised in 2018. No studies have investigated whether the addition of CT to radiographic diagnosis improves the inter-rater reliability of classifying 31A fractures with the current AO/OTA criteria. The study aimed to test the hypothesis that the addition of three-dimensional CT (3D-CT) to radiographic diagnosis would improve diagnostic reliability.

Clinical Outcome of Mid-Length Proximal Femoral Nail for Patients With Trochanteric Hip Fractures: Preliminary Investigation in a Japanese Cohort of Patients More Than 70 Years Old.

Introduction: The TFN-ADVANCED Proximal Femoral Nailing System (TFNA) 235 mm (DePuySynthes) and Proximal Femoral Nail Antirotation (PFNA)-II 240 mm (DePuySynthes) were developed to obtain better stability for patients with trochanteric hip fractures without increasing surgical time and amount of blood loss. However, there are currently no studies concerning clinical and radiological outcomes of patients treated using these proximal femoral nails (PFNs) that have been performed in the Japanese population. The aim of this study was to retrospectively evaluate the clinical outcomes associated with 235 to 240 mm PFNs for Japanese patients >70 years old with trochanteric hip fractures who could walk independently before the injury.

Clinical outcomes of open reduction and internal fixation for intra-articular complex tibial plateau non-union with 3-year minimum follow-up.

Background: A tibial plateau fracture is one of the most challenging fractures for both knee and trauma surgeons because of the high incidence of post-traumatic knee osteoarthritis. To our knowledge, there has been no study concerning the clinical outcomes after surgery in patients with non-union of complex intra-articular tibial plateau fractures. Thus, the present study aimed to assess and report the clinical outcomes in them.

Management of infected non-union of subtrochanteric fracture: Two cases.

Infected non-union of subtrochanteric fractures is challenging to treat. We experienced two cases and had good clinical results. Treatment strategy comprised debridement without hesitation after considering later limb lengthening; insertion of the proximal lateral bone edge spike into the distal bone marrow cavity until achieving medial-side bony contact and holding good alignment to compensate for the medial-side bone loss, according to the modified Dimon method; and internal fixation with an angled plate in the decubitus position.
