<prompt> All of the following are true about the upper end of tibia except -Ossification center for the upper end fuses by 18 yearsIt gives attachment to meniscal cartilage on intercondylar areaIt gives attachment to semi-membranosusPosterior aspect of patella articulates with upper end of tibia laterally  <response>: Secondary ossification centre for upper end fuses with the shaft at 16- 18 years.Attachment in the intercondylar area Before backwards- Anterior horn of medial meniscus- Anterior cruciate ligament- Anterior horn of lateral meniscus- Posterior horn of lateral meniscus- Posterior horn of medial meniscus- Posterior cruciate ligamentPosterior surface of patella, only the upper 34th is articular, which articulates with femur at different phases of movement of knee joint.
