Longitudinal morphological change of acetabular subchondral bone cyst after total hip arthroplasty in developmental dysplasia of the hip

European Journal of Orthopaedic Surgery & Traumatology, 2018
The purpose of this study is to clarify morphological changes of acetabular subchondral bone cyst after total hip arthroplasty for osteoarthritis secondary to developmental dysplasia of the hip.Two hundred and sixty-one primary cementless total hip arthroplasties of 208 patients, 18 males, 190 females, were retrospectively reviewed.

The Location and Severity of Preoperative Subchondral Bone Marrow Lesions Were Not Associated With Inferior Postoperative Outcomes After Medial Unicompartmental Knee Arthroplasty or Total Knee Arthroplasty

The Journal of Arthroplasty, 2016
Inferior outcomes for medial unicompartmental knee arthroplasty (UKA) patients with preoperative medial tibial bone marrow lesions (BMLs) were recently reported. The purpose of this study was to compare the location and severity of BML on postoperative outcomes after medial UKA and TKA using a larger sample size and more rigorous magnetic resonance ...

Total Hip Arthroplasty is the Most Effective Treatment for Atraumatic Subchondral Insufficiency Fractures of the Femoral Head.

Bulletin of the Hospital for Joint Disease (2013), 2023
Subchondral insufficiency fracture of the femoral head (SIFH) is a relatively newly used diagnosisfollowing an insidious onset of hip pain in individuals without apparent antecedent trauma. The aim of this study was to investigate the outcomes of a consecutive series of patients with SIFH treated at one institution.A total of 93 patients aged 23 to 91 ...

Differentiating Subchondral Insufficiency Fracture from Osteonecrosis May Help Avoid Unnecessary Total Hip Arthroplasty

The Journal of Hip Surgery, 2018
AbstractDifferentiation of subchondral insufficiency fracture (SIF) from osteonecrosis (ON) is clinically important. The purpose of this study is to correlate the X-ray and magnetic resonance imaging (MRI) findings in cases that have been diagnosed histopathologically as SIF or ON, define features on X-ray and MRI analysis, and identify clinical ...

Robotic-assisted unicompartmental knee arthroplasty in a patient with combined medial compartment arthritis and subchondral defect of the medial femoral condyle

The Knee, 2012
Subchondral defects, or severe osteoarthritic changes, of the medial compartment may complicate component positioning and require proper planning and exact placement to ensure adequate and stable fixation and proper postoperative kinematics. This is a case report on our experience with a CT-based robotic tactile guidance system for unicompartmental ...

Human bone marrow mesenchymal stem cell injection in subchondral lesions of knee osteoarthritis: a prospective randomized study versus contralateral arthroplasty at a mean fifteen year follow-up

International Orthopaedics, 2020
Recently, mesenchymal stem cells (MSCs) have been proposed as potential treatment modalities for knee osteoarthritis. However, indications and long-term results have not been frequently reported. The purpose of this study was to determine whether bone marrow lesion on MRI are predictive of risk progression to total knee arthroplasty during the first ...

Positive effect of removal of subchondral bone plate for cemented acetabular component fixation in total hip arthroplasty

The Bone & Joint Journal, 2015
We hypothesised that the removal of the subchondral bone plate (SCBP) for cemented acetabular component fixation in total hip arthroplasty (THA) offers advantages over retention by improving the cement-bone interface, without jeopardising implant stability.

Total shoulder arthroplasty with minimum 5-year follow-up: does the presence of subchondral cysts in the glenoid increase risk of failure?

Journal of Shoulder and Elbow Surgery, 2018
This study evaluated the effect of cystic changes in the glenoid on postoperative outcomes and implant survival after total shoulder arthroplasty (TSA).From 2004 to 2012, 75 patients underwent TSA for primary osteoarthritis with minimum 5-year follow-up.

Moderate-to-Severe Varus Deformity Is Associated With Conversion to Arthroplasty in Patients Who Have Subchondral Insufficiency Fracture of the Knee

The Journal of Arthroplasty
Although untreated subchondral insufficiency fractures of the knee may result in progression of osteoarthritis, leading to arthroplasty in approximately 30% of cases, the factors associated with the requirement for arthroplasty remain unknown. We hypothesized that varus deformity would be associated with increased risk of nonoperative treatment failure
