Anterior cruciate ligament tear in Hong Kong Chinese patients.

Objective: To investigate the associations between patient sex, age, cause of injury, and frequency of meniscus and articular cartilage lesions seen at the time of the anterior cruciate ligament reconstruction.

Setting: University affiliated hospital, Hong Kong.

Patients: Medical notes and operating records of 672 Chinese patients who had received anterior cruciate ligament reconstruction between January 1997 and December 2010 were reviewed.

Femoral radiographic landmarks for popliteus tendon reconstruction and repair: a new method of reference.

Background: Although the popliteus muscle-tendon complex is one of the most important structures in controlling posterolateral rotatory stability of the knee, not much literature has been reported concerning the use of femoral radiographic landmarks of the popliteus tendon in repair and reconstruction.

Hypothesis: By using standardized radiographic techniques, the femoral insertion of the popliteus tendon could be more precisely determined by the Blumensaat line than by the extension line of the posterior cortex.

Study Design: Descriptive laboratory study.

Tunnel positions in transportal versus transtibial anterior cruciate ligament reconstruction: a case-control magnetic resonance imaging study.

Purpose: The purpose of this study was to examine the difference in the position of bone tunnels prepared by the transportal technique versus the transtibial technique in anterior cruciate ligament (ACL) reconstruction.

Methods: A consecutive series of 42 patients receiving single-bundle ACL reconstructions were recruited between July 1, 2007, and December 31, 2008. The preparations of the femoral tunnel were performed by the transtibial technique in the first 21 cases and by the transportal technique in the subsequent 21 cases.

Early results of all-inside meniscal repairs using a pre-loaded suture anchor.

Objectives: To report the clinical and radiological results of all-inside meniscal repairs using a pre-loaded suture anchor.

Design: Case series.

Setting: Regional hospital, Hong Kong.

Distal femur rotation relates to joint obliquity in ACL-deficient Chinese.

Background: The lower limb osteometry of Chinese differs from that of whites. The joint line of the knee in the coronal plane in Chinese is more medially inclined and the posterior condylar angle of the distal femur in the axial plane is larger. However, it is unclear whether there is any direct association between the coronal plane and axial plane osteometry.

Delay in ACL reconstruction is associated with more severe and painful meniscal and chondral injuries.

Purpose: The goal of our study was to investigate the associations between surgical delay, pain and meniscus, and articular cartilage lesions seen at the time of ACL reconstruction.

Methods: One hundred and sixty-two consecutive patients who had received ACL reconstruction were recruited. The preoperative International Knee Documentation Committee (IKDC) questionnaires, and cartilage and meniscal lesions seen at the time of surgery were analysed.
