Realignment osteotomies in the treatment of chronic instabilities of the knee associated with malalignment (case report)

INTRODUCTIONChronic knee instabilities associated with malalignment are complex and unusual disorders with various treatment modalities.PRESENTATION OF CASEWe describe two cases of chronic instability of the knee with malalignment. Furthermore, we describe realignment osteotomies as the treatment of chronic instabilities for these cases.DISCUSSIONIn the literature review, there are few cases of chronic instabilities treated by realignment osteotomy. Only soft tissue procedures are not enough to treat the chronic instability of the knee with limb malalignment.CONCLUSIONDeformity analysis with good preoperative planning and then realignment of the lower extremity, lead to better results and will preserve the joint from instability.
