The consultant for prosthetic surgery at King Khalid University, Dr. Muhammad Al-Otaibi, has proven the specificity of the Saudi knee size in the field of orthopedics and artificial prostheses of the knee joint, relative to the joints of European and North American countries (Caucasian), used in the industrial installations currently used in the Kingdom, through specialized scientific research published in Saudi Medical Journal finally. The research comes in view of the need for a large segment of citizens for artificial implants and the increasing demand for them in order to change the way of life as societies change. Al-Otaibi stressed the importance of scientific research and its employment in what serves society, which is one of the most important pillars and functions of universities and what they provide to humanity, pointing out that researching the privacy of the Saudi knee is an urgent need, given the high cases of patients who are eligible for knee joint replacement operations.
Dr. Al-Otaibi pointed out that orthopedic surgeons from outside the countries that manufacture artificial joints (European and North American countries) noted that there is a percentage of mismatch if they are used in other countries, especially in Asia, explaining that the mismatch of prosthetic joints available in the market from several companies has led to Patient dissatisfaction, through the presence of some pain as a result of the mismatch, which confirmed his desire through his research to document this scientifically, with the help of radiology to check the knee size readings of patients through accurate CT scans. The research study showed the need for small industrial joint sizes commensurate with the bone size of the Saudi knee for a large part of patients in the Kingdom, after applying the methodology for evaluating all computerized tomography images of the knee obtained from southwestern Saudi Arabia, which confirmed that Saudi patients They have “morphological” features that do not match the widely available artificial implants designed for Caucasian knees, and the need to design new implants that take these differences into account.
It is noteworthy that the study was carried out on 100 knees of 50 Saudi male and female patients whose ages ranged between 28-85 years. No statistical differences were found in measures of age and angle of “Sasaki” between male and female patients, and the difference in joint measurements (Caucasian) available, Which is much larger in males than in females, but the size of the knee joint in the research sample of patients proved the small bone formation of the joint and the need to find joints that take this into account.
