|
Purpose: This study was performed to find out whether tibial bone defect preceeding the surgery has an effect on the outcome of patients who have undergone total knee replacement therapy with an evaluation period of more than five years.
Materials and Methods: Osteoarthritis patients who were treated with total knee replacement and evaluated for more than 5 years were selected, of which 42 patients were with tibial bone defects, and 21 without. Clinical evaluation were made on the basis of pre- and post-operative Knee Society Knee Score and Functional Score, radiological evaluation using the American Knee Society Score. and range of motion, tibio-femoral angle, subjective satisfaction, complication were evaluated.
Results: Knee fuction score and subjective satisfaction of the two groups showed significant improvement after the surgery, but comparison between the two was statistically insignificant. Radiological evaluation showed radiolucency in zone 1 and 2 of tibia in the majority of both groups, but dissociation of the inserted device was not shown.
Conclusion: In the cases of tibial bone defect, bone cement, screw fixation enforced with autograft, and wedge metal insertions can be considered to be effective in treating patients by total knee replacement surgery.
