Follow-up of a new arthroscopic technique for implantation of matrix-encapsulated autologous chondrocytes in the knee.

Purpose: The purpose of this study was to evaluate the clinical and sequential imaging follow-up results at a mean of 36 months after an arthroscopic technique for implantation of matrix-encapsulated autologous chondrocytes for the treatment of articular cartilage lesions on the femoral condyles.

Methods: Ten patients underwent arthroscopic implantation of autologous chondrocytes seeded onto a bioabsorbable scaffold. The patients were evaluated clinically using a visual analog scale (VAS) for pain and International Knee Documentation Committee (IKDC), Lysholm, and Tegner scores.

High dietary calcium intake decreases bone mobilization during pregnancy in humans.

Unlabelled: Calcium metabolism of the mother is modified during pregnancy because of the mineralization of the fetus skeleton.

Objective: To evaluate the association of calcium intake and bone demineralization during pregnancy.

Material And Methods: At each trimester of pregnancy a validated food frequency intake questionnaire was administered to assess individual daily calcium intake in a cohort of 206 pregnant women, residents of Mexico City.
