A Case of Subchondral Insufficiency Fracture of the Knee at Lateral Femoral Condyle Treated With Unicompartmental Knee Arthroplasty.

Spontaneous insufficiency fracture of the knee is a potentially devastating yet poorly understood disease entity that can lead to secondary osteoarthritis. Most cases involve the medial femoral condyle, and the lateral femoral condyle is rarely affected. The optimal treatment for spontaneous insufficiency fracture of the lateral femoral condyle remains undetermined, and there are no previous dedicated reports on treatment outcome with unicompartmental knee arthroplasty.

A Cross Sectional Study on Knowledge, Attitude and Practice related to Human Papillomavirus Vaccination for Cervical Cancer Prevention between Medical and Non-Medical Students in Hong Kong.

Background: One of the most important aetiologies of cervical cancer is Human Papillomavirus (HPV) infection. While vaccination is an effective way in preventing high risk HPV infection, HPV vaccine uptake rate in Hong Kong has been low. Considering the proven effectiveness of HPV vaccination and the low vaccination uptake rate in Hong Kong, this study was conducted to compare the knowledge, attitude and practice towards HPV vaccination for cervical cancer prevention between medical and non-medical students in the University of Hong Kong.
