Open-wedge high tibial osteotomy in patients with discoid lateral meniscus.

Background: There are concerns about the progression of the lateral osteoarthritis (OA) should be taken into account when high tibial osteotomy (HTO) is performed in patients with discoid lateral meniscus (LM). This study evaluated the clinical results of HTO in patients with discoid LM and elucidated factors affecting the results.

Methods: This study evaluated 32 female patients with varus deformity and medial OA.

The patellofemoral joint does not deteriorate clinically after open-wedge high tibial osteotomy.

Background: After high tibial osteotomy (HTO), the loading of the lateral compartment can be increased. Moreover, the change of patellar height may adversely affect the patellofemoral joint and functional outcomes.

Hypothesis: We hypothesized that the cartilage of the lateral compartment and patellofemoral joint would worsen after open-wedge HTO and the overcorrection of HTO could worsen the cartilage state of the patellofemoral joint.

Does proximal femoral nail antirotation achieve better outcome than previous-generation proximal femoral nail?

Background: There are few studies in the literature comparing the clinical outcomes and radiographic results of proximal femoral nail (PFN) and proximal femoral nail antirotation (PFNA) for pertrochanteric femoral fracture (PFF) in elderly patients.

Aim: To evaluate both clinical and radiographic outcomes after fixation with PFN and PFNA in an elderly patient population.

Methods: One hundred fifty-eight patients older than 65 years with PFF who underwent fixation with either PFN or PFNA were included.

Can medial stability be preserved after open wedge high tibial osteotomy?

Purpose: This study evaluated the medial joint stability after high tibial osteotomy (HTO) releasing the superficial medial collateral ligament (sMCL) without cutting and repairing.

Methods: Twenty-one patients who performed HTO were enrolled. After an L-shaped incision was made in the pes anserinus, the sMCL was released from the distal portion during surgery.

Metastatic spinal tumor.

In accordance with extending survival periods of cancer patients, number of consecutively developing metastatic spinal tumor is also increasing. There have been improvements in the treatment results of metastatic spine tumor by virtue of the developments in diagnostic radiology, chemotherapy, adjuvant treatment, operative device and technique, discrete preoperative plan, and standardized operation. Accordingly, surgical indication has also increased.

Long-term results of anterior cruciate ligament reconstruction using bone-patellar tendon-bone: an analysis of the factors affecting the development of osteoarthritis.

Purpose: To evaluate the clinical outcomes and incidence of knee osteoarthritis (OA) and the factors associated with the onset of OA in the 3 compartments of the knee joint separately after anterior cruciate ligament (ACL) reconstruction with bone-patellar tendon-bone autograft.

Methods: Clinical and radiologic assessments were obtained from 117 patients (80.1%).

A comparative study between thoracoscopic surgery and posterior surgery using all-pedicle-screw constructs in the treatment of adolescent idiopathic scoliosis.

Study Design: A retrospective comparative study.

Objective: To present the results of thoracoscopic surgery in the treatment of adolescent idiopathic scoliosis (AIS) and to compare the results of thoracoscopic surgery with those of posterior surgery.

Summary Of Background Data: Although racoscopic scoliosis correction has attracted attention since the early 2000s, its use has declined gradually, whereas posterior surgery using pedicle screws has become popular.
