Video Summary

In this video, the speaker discusses a study on type 2 tibial spine fractures. The study aimed to determine if bringing the fractures into an extended position reliably reduces them. The study used MRI images and included 10 patients under 18 years of age. The results showed that the displacement of the fragments only reduced by less than a millimeter in the extended position. The study had some limitations, including a small sample size and difficulty in patient collection. The speaker concludes that none of the reductions went below 4 millimeters and more research is needed to determine how much displacement is too much. Another study discussed in the video focused on all-inside anterior cruciate ligament reconstruction with hamstring autograft. The study aimed to consistently yield grafts with a diameter of 8mm or larger. The technique involved harvesting the semitendinosus tendon and, if deemed insufficient, also harvesting the gracilis tendon. The results showed that the technique consistently achieved grafts of at least 8mm, with the majority being 8.5mm or larger. The technique allows surgeons to achieve the ideal graft size without using allograft tissue.
