arthroplasty and high tibial osteotomy are utilized, in general, for the
treatment of similar pathology. Their
relative use varies with the age or demands of the patient and the experience
of the surgeon. There are some
relative indications and contra indications for both procedures. High
tibial osteotomy is utilized in the younger, higher demand patient, who will
tolerate some degree of residual discomfort in return for less restriction on
his/her activity level. Ligamentous
laxity and flexion deformity are relative contra indications. However, recent techniques such as opening
wedge osteotomies and allograft material have allowed us to expand our
indications. Soft tissue tensioning
can also be accomplished with the use of a unicompartmental prosthesis, but
patient selection is extremely important.
The morbidly obese patient or the osteoporotic patient are poor candidates for unicompartmental knee replacement. When osteotomies become too complicated, it is often prudent to use a uni or TKA.  Previous Lecture
