Midterm Outcome after Mega-Prosthesis Implanted in Patients with Bony Defects in Cases of Revision Compared to Patients with Malignant Tumors.
Use of mega-prostheses is a common option for the treatment of patients with malignant tumors as well as in patients with large osseous defects at the time of revision surgery. No studies have compared the two groups to determine whether there is a relative difference in clinical outcomes. We performed a midterm-outcome-study to evaluate our results in these two patient populations. Deep infection was found more often in our revision group (29.5% vs. 9.1%), however no significant differences in WOMAC-results could be found between the two groups. Surgeons should recognize the high complication rate as well as the differences in results using mega-prostheses in these two distinct groups of patients.
