1. When the center of the best-fitted circle of the acetabulum coincide with the center of the femoral head, the concruency of the joint is considered normal (CnI =100%).The app calculates automatically the congruency index.
2. Joint congruency can be rated subjectively according to the surgeons experience but according to international literature, evaluation and monitoring hip joint congruency is crucial to judge and predict the outcome of treatment.
3. Although corrective hip osteotomies for the realignment of the dysplastic acetabulum is the main goal of treatment strategies, if the joint space congruency remain fair this end up in failure.

5. All information received from the software output must be clinically reviewed regarding its plausibility before patient treatment! Congruence Index App indicated for assisting healthcare professionals.
6. With transparent circular template-Moses template- you try to find the best-fitted circle superimposed over the femoral head, you mark the femoral head center and with the same manner you locate the acetabular center of the weight bearing zone.
7. Congruence is present when the center of the femoral head (ball) and that of the acetabulum (socket) coincide.
8. Lack of hip congruence between the femoral head and the acetabulum leads to increased local contact stresses, degeneration and consequently to premature arthritis.
9. The App measures objectively the congruence and gives values as percentage (Congruence Index) which can be used for evaluation or comparisons of treatments modalities like acetabular osteotomies in developmental dysplasia or Legg-Calve-Perthes disease of the hip.
10. The results are printed as a percentage of congruency of the hip joint and the hip is categorized as normal or abnormal.
11. Joint congruency as an indication for rotational acetabular osteotomy.
