The condition is generally chronic, and is marked by tenderness and swelling of the bone and pain. Acute periostitis is due to infection, is characterized by diffuse formation of pus, severe pain, constitutional symptoms, and usually results in necrosis. It can be caused by excessive physical activity as well, as in the case of medial tibial stress syndrome (also referred to as tibial periostalgia, soleus periostalgia, or shin splints).

High tibial osteotomy High tibial osteotomy High tibial osteotomy is an orthopaedic surgical procedure which aims to correct a varus deformation with compartmental osteoarthritis. It is usually reserved for younger patients who are generally more active. Angular deformities were first described by Mikulicz-Radecki in 1880. He observed that the axis of the lower extremity passes through the three joints of the hip, knee and ankle in normal individuals and the knee center deviates from this line in angular deformities of the knee. In this case, the medial compartment will bear the weight in genu varum and the lateral compartment will bear weight in
