Background: Osteoporosis is the most common metabolic disorder affecting bone which develops because of normal ageing, excessive bone loss during adulthood and impaired development of peak bone mass. Awareness among physicians is vital for the early detection and timely treatment and hence fractures prevention. The present study was carried out to study the knowledge, attitude and practice towards osteoporosis among general practitioners working in Al Majmaah, KSA. Methodology: This crosssectional research was conducted among all the qualified family physicians, general practitioners and resident doctors in Majmaah province, KSA. Data collection was done based on a standardized KAP questionnaire. Results: All the data were entered and analysed according to the intentions of the present work. Good level of knowledge concerning the diagnosis was observed among the study subjects and a high proportion of respondents believed in the preventive strategies of the disease. Responses were obtained from total of43 practitioners who included 23.3% female, and 76.7% male in and around Majmaah province. Majority (72.1%) of the respondent's attitude was that osteoporosis has major effect on the health of the community. In relation to practice aspects, prescription of 76.7% responders includes bisphosphonates as the most commonly used drug for treatment of osteoporosis. Conclusion: A considerable level of knowledge and positive attitude towards osteoporosis was found; however, practices for the prevention of osteoporosis still need improvement. There is a need to extend the medical knowledge of general practitioners in Al Majmaah Province, KSA, regarding the contemporary management of osteoporosis and its risk factors. Professional training programs are required to enhance the practitioner's knowledge and attitude to improve their practices.

Introduction: Total knee arthroplasty (TKA) is considered a highly recommended procedure, to improve the life of patients suffering from knee arthritis by relieving pain and deformity. Knee morphology and anthropomorphic features have evolved as the most reliable source of information to design TKA prostheses. But unfortunately, the amorphic features of Western patients are the preferred choice of data for the development of suitable implants. This study is conducted for commencing to evaluate the geometric parameters of the knee joints of Saudi Arabian male and female subjects which is indispensable to the design of knee prosthesis used for compatriotic patients. Material and Methods: A total of 13 parameters of tibia and femur were studied in a group of 150 normal subjects including 110 females and 40 males. A subsequent magnetic resonance imaging scan was done for all the studied cases and a reproducible result was obtained. Results: The Saudi females were found to have smaller dimensions of parameters of tibia and femur than those in Saudi males. The results when compared with other reports from different countries, we find marked difference in their dimensions. Discussion and Conclusion: Our study suggests that there exists a morphological mismatch between the knee anatomy of people of Saudi Arabia and people of other countries. Implantation of such implants prepared on the basis of outsider data could not justified to use in the Saudi population.
