Description of intervention(s) / exposure
In the initial stage of the reconstructive surgery, the orthopedic surgeon, using a crown drill and a guide with an olive, takes cylindrical fragments of the spongy bone from the side of the proximal part. The collection of the graft takes about 5 minutes and is made of a skin cut with a length of 15 millimeters. During follow-up visits (2 weeks, 6 weeks, 12 weeks and a year and 2 years after the surgery) at the orthopedic clinic, the aesthetics of the scar and symptoms from the graft collection site will be assessed. As the control group will have their transplants collected from another place, the study cannot be randomized.

Comparator / control treatment
In the initial stage of the reconstructive surgery, the orthopedic surgeon, using a crown drill and a guide with an olive, takes cylindrical fragments of the spongy bone from the side of the iliac region. The collection of the graft takes about 5 minutes and is made of a skin cut with a length of 50 millimeters. During follow-up visits (2 weeks, 6 weeks, 12 weeks and a year and 2 years after the surgery) at the orthopedic clinic, the aesthetics of the scar and symptoms from the graft collection site will be assessed.

Summary
Brief summary
Purpose of the study is to prove that minimally invasive method of obtaining autgenic spongy bone grafts from the proximal part of the tibia is a safe method that allows for good cosmetic results and does not cause pain from the site of the graft collection. This procedure is efficent an safe and doesn't cause any artifical pain .
