Evaluation of the usefulness of non-weight-bearing tunnel view using X-ray in the short term after medial meniscus posterior root tear onset: a retrospective study.

Background: This study aimed to examine whether the non-weight-bearing tunnel view X-ray is effective for short-term evaluation of medial meniscus posterior root tear (MMPRT) by assessing the X-ray characteristics at the initial and follow-up visits.

Methods: This was a retrospective longitudinal study of 26 enrolled knees diagnosed with MMPRT on magnetic resonance imaging. The distance between the medial tibial eminence and medial femoral condyle (MTE-MFC distance) and medial tibiofemoral joint (MTFJ) width were measured by obtaining non-weight-bearing tunnel view and frontal view X-ray radiographs.

Medial Meniscus Posterior Root Reconstruction and Open-Wedge High-Tibial Osteotomy for Medial Meniscus Posterior Root Tear With Varus Knee Alignment: A Retrospective Study on Short-Term Outcomes.

Purpose: We describe 13 cases of medial meniscus posterior root tear (MMPRT) with varus knee alignment treated with medial meniscus posterior root reconstruction (MMPR-R) and open-wedge high-tibial osteotomy (OWHTO) to identify an optimal MMPRT treatment.

Methods: We retrospectively reviewed 13 patients (mean age: 66.3 ± 8.

Osteosynthesis with Arthroscopy of a Nonunited Tibial Anterior Cruciate Ligament Avulsion Fracture 30 Years after Injury.

There are a few reports on the treatment of nonunited tibial anterior cruciate ligament (ACL) avulsion fractures. To our knowledge, this is the first report of a case of nonunited tibial ACL avulsion fracture 30 years after injury. A 36-year-old woman injured her knee during a road traffic accident 30 years ago.

Type V Tibial Tubercle Avulsion Fracture with Suspected Complication of Anterior Cruciate Ligament Injury: A Case Report.

: Type V tibial tubercle avulsion fractures are extremely rare; therefore, information on them remains limited. Furthermore, although these fractures are intra-articular, to the best of our knowledge, there are no reports on their assessment via magnetic resonance imaging (MRI) or arthroscopy. Accordingly, this is the first report to describe the case of a patient undergoing detailed evaluation via MRI and arthroscopy.

Medial Meniscus Posterior Root Reconstruction and Open- Wedge High Tibial Osteotomy for Medial Meniscus Posterior Root Tear with Varus Knee: A Case Report.

Introduction: Pull-out suture, suture anchor, and open- wedge high tibial osteotomy have been widely used for surgical treatment of medial meniscus posterior root tear, and relatively good clinical results have been reported. However, radiologic and arthroscopic findings are not sufficient. This report describes the first case, to the best of our knowledge, of medial meniscus posterior root reconstruction and high tibial osteotomy for medial meniscus posterior root tear with varus knee.

Localized Pigmented Villonodular Synovitis of the Bilateral Knee: A Case Report.

Introduction: Localized pigmented villonodular synovitis (PVNS) is a rare and benign condition of synovial tissue proliferation that affects the joints, tendon sheaths, and bursae. This case report is the first to describe a patient with a diagnosis of localized PVNS of the knee after presentation with bilateral and simultaneous onset of associated knee pain.

Case Report: A 28-year-old Japanese woman presented to our hospital with a 1-year history of bilateral knee pain and right knee locking that started 1 month ago.

Arthroscopic Osteophyte Resection for Osteophyte-Induced Popliteal Impingement.

Popliteal tendinitis causes lateral knee pain. A cause is impingement of the popliteal tendon by lateral femoral condylar osteophytes. Conservative and surgical treatments have been reported; however, popliteal impingement is a relatively rare disease, and no treatment has been established.

Arthroscopic Medial Meniscus Posterior Root Reconstruction and Pull-Out Repair Combined Technique for Root Tear of Medial Meniscus.

Repair of medial meniscus posterior root tear is important in preventing rapid progression of knee osteoarthritis. There are many repair techniques for medial meniscus posterior root tears, and good clinical results have been reported. Conversely, in terms of improving extrusion and healing meniscal injuries, sufficient results have not been obtained.

Consistent modelling of material weight loss and gas release due to pyrolysis and conducting benchmark tests of the model-A case for glovebox panel materials such as polymethyl methacrylate.

It is necessary to consider how a glove box's confinement function will be lost when evaluating the amount of radioactive material leaking from a nuclear facility during a fire. In this study, we build a model that consistently explains the weight loss of glove box materials because of heat input from a flame and accompanying generation of the pyrolysis gas. The weight loss suggests thinning of the glove box housing, and the generation of pyrolysis gas suggests the possibility of fire spreading.
