“…At present, no elderly patients with congenital absence of a ligament have been found. The literatures point out that some patients may not have any symptoms (patients with absence or incompetence in a cruciate ligament often do not complain about joint instability), because they may have adapted to those pathological anatomical conditions[10,20]. However, with age or after sudden trauma, the balance of the knee for which the patient has already compensated is destroyed, causing knee instability, recurrent dislocation, and even pain and other symptoms that accelerate the progression of knee osteoarthritis[21].…”

BACKGROUNDHypoplasia of bilateral cruciate ligaments is a rare congenital malformation. The diagnosis of such diseases and indications for the various treatment options require further analysis and discussion.CASE SUMMARYThe patient is a 26-year-old Chinese woman who has been suffering from knee pain since the age of 8 years, 2-3 episodes a year. Three years ago, due to the practice of advanced yoga poses, the frequency of left knee pain increased, requiring prompt medical treatment. Magnetic resonance imaging demonstrated an absence of both anterior and posterior cruciate ligaments of both knees with abnormal posterior tilting of the tibial plateau. Bilateral subluxation of the knee joint was also found, therefore tibial osteotomy was performed. The patient reported at the 24 mo follow-up that the frequency of pain and instability had been reduced and function restored.CONCLUSIONOsteotomy may be an effective method to treat patients with congenital cruciate ligament deficiency with posterior tibial plateau tilting. The diagnosis of congenital cruciate ligament deficiency shall be based on the combination of patient’s medical history, clinical manifestations, and findings from imaging to avoid possible misdiagnosis. Based on the symptoms, frequency of attacks, and intent of the individual, appropriate treatment options shall be identified.

The human knee joint usually suffers progressive deterioration with time. The conventional cure of this issue is to replace it with an alternate knee by applying the prosthesis implant. The reason is that the process causes the abrasion of the different materials rather than just sliding or rolling. This study aims to develop the numerical measurement of the knee prosthesis’s geometry, which fulfils the mechanical requirements of the human knee. The MSC.ADAMS programme was applied to demonstrate the movement of the human knee joint in terms of rotation and flexion. The changes between the condyles of the developed multibody of the prosthesis related to the flexion angle ranging from 20–120° were investigated and presented. The boundary conditions were determined, and simulations performed using the ADAM’s programme. An average value of 0.7 was reached for the slip ration, with the maximum getting up to 0.79. An angle between 110–120° for the flexion angle was obtained. It can be said that the application of the multibody model saves time as there is no involvement of the tibia and the femur as required for the knee prosthesis. More importantly, as the application of the test machine is omitted in our process, our model’s approximations to a human knee are carried out directly. Without cost, several measurements for the knee prosthesis could be made and repaired. The study results provide the necessary insight for future tests regarding the movement of the knee joint.
