In the long run, eliminating the fibular bone should result in no difficulties walking. Following surgery, you will be placed on bed rest for a day or two. Hopefully, you'll be sitting outside in a chair soon after this. At the conclusion of the first week, you will be able to walk with the assistance of physiotherapists. You may require crutches until the wound has healed and you've begun strengthening your leg muscles. During the first year after surgery, you can expect to experience occasional pain, swelling, and instability in the remaining knee. However, most patients are able to work with these problems by performing certain exercises. If you continue to have pain beyond a year, then another operation might be required. The functional importance of the ankle joint is that it allows us to stand up straight with our legs under control. The fibula acts as a support underneath the tibia; without it, the lower leg would be very weak. The fibula also provides stability to the ankle because it connects to several bones including the talus, heel, and arch of foot. In addition, it controls the angle at which the lower leg meets the thigh. People usually think that bones are solid structures that cannot be changed after birth, but this is not true. Bone tissue is constantly remodeled and rebuilt. Old bone cells are absorbed by special cells called macrophages, which are part of the immune system.
