Background: This study aimed to determine whether physical findings reflecting triceps surae strength recovery could predict return to activities such as jogging and sports and whether patients' age and sex would influence recovery of triceps surae strength postoperatively.
Methods: Between 2009 and 2013, 96 consecutive cases of postoperative acute Achilles tendon rupture were reviewed. The postoperative triceps surae strength recovery rate was investigated in all patients by using half body weight 1-time heel rise, full body weight (FBW) 1-time heel rise, FBW 20-time heel rise, jogging, and full return to sports activities.
Purpose: Intrafraction prostate displacement (IFPD) through the course of conventionally fractionated radiotherapy was observed by real-time tracking.
Materials And Methods: IFPD was observed by using a CyberKnife real-time tracking system over 39 serial fractions in two patients. Stereoscopic X-ray images tracking the implanted fiducial markers were obtained with mean intervals of 58 s.
Background: Medial collateral ligament tibial avulsion is rare. Consequently, diagnostic criteria and a treatment regimen for medial collateral ligament tibial side avulsions remain to be established. The purpose of this study is to clarify the clinical features of medial collateral ligament tibial side avulsions.

Of 414 strains that were isolated from specimen (mainly from sputum) and assumed to be bacteria causing in infection, 407 strains were examined. The isolated bacteria were: Staphylococcus aureus 64, Streptococcus pneumoniae 96, Haemophilus influenzae 87, Pseudomonas aeruginosa (non-mucoid) 52, P.

Purpose: The purpose of this study was to evaluate the clinical results of anatomic double-bundle (DB) anterior cruciate ligament (ACL) reconstruction in which anatomic position of femoral socket apertures was validated using three-dimensional (3D) computed tomography (CT) modelling.
Methods: Anatomic DB ACL reconstructions with hamstring autografts were performed in 34 patients. Two femoral sockets were created through a far anteromedial (AM) portal behind the lateral intercondylar ridge with the assistance of intraoperative 3D fluoroscopic navigation.
Revision anterior cruciate ligament (ACL) reconstruction is accompanied by several technical challenges that must be addressed, such as a primary malpositioned bone tunnel, pre-existing hardware, or bone defects due to tunnel expansion. We describe a surgical technique used to create an anatomic femoral socket using a 3-dimensional (3D) fluoroscopy-based navigation system in technically demanding revision cases. After a reference frame is rigidly attached to the femur, an intraoperative image of the distal femur is obtained, which is transferred to a navigation system and reconstructed into a 3D image.

Background: The purpose of this study was to evaluate the influence of image-free computer-assisted navigation system update on outcome in total knee arthroplasty.
Methods: Thirty-three knees were replaced using the Stryker 3.1 image-free navigation system and 49 knees were replaced using the Stryker 4.

A young female athlete suffered from the residual instability of the knee after anterior cruciate ligament (ACL) reconstruction with hamstring autograft. The 3-dimensional (3-D) CT scan showed the "high noon" positioning of the primary femoral bone tunnel. The revision surgery with anatomic double-bundle technique was performed two years after the primary surgery and the femoral tunnels were created with the assistance of the 3-D fluoroscopy-based navigation.

These defects have limited ability to heal and may progress to osteoarthritis. The prevalence of knee osteoarthritis among athletes is higher than in the non-athletic population.

Methods: Thirty-four patients were divided into 2 groups of 17 depending on the sequence of preparation of the 2 femoral tunnels. In group A, the AM tunnel was prepared first, whereas the PL tunnel was prepared first in group P.
In anatomic double-bundle anterior cruciate ligament (ACL) reconstruction, it is more technically demanding, even for experienced surgeons, to place 2 femoral tunnels within the ACL attachment than to place 2 tibial tunnels. We describe a technique using a three-dimensional (3-D) fluoroscopy-based navigation system to place 2 femoral tunnels accurately. After a reference frame is rigidly attached to the femur, an intraoperative image of the distal femur is obtained.

Catastrophic antiphospholipid syndrome (CAPS) is a small subset of APS characterized by widespread systemic thrombotic disease with multiorgan failure. We herein describe an autopsy case of CAPS who developed severe respiratory failure due to acute respiratory distress syndrome (ARDS) as the initial manifestation.
