Background:Patella is uncommon site for all of primary and metastatic bone tumors; but in some reports chondroblastoma and giant cell tumor were the most common tumors in this site. Surgical management varies in patients based on the kind of tumor. Also, function of knee after treatment varies based on the kind of the surgery and tumor. Previous surveys on this object are a few case reviews or reports in literature reviews.Methods:13 patients with patellar tumor treated between 1985-2006 in Shafa-Yahyaian, Pars, and Milad hospitals were assessed. Signs, symptoms and paraclinical data before and after operation were evaluated. All of the patients underwent surgical management. Results of treatment were assessed in long term fallow up.Findings:From 13 patients, 5 cases were chondroblastoma, 3 cases were giant cell tumor, 2 were ABC, 2 were metastases, and 1 case was UBC.Pain and knee effusion were the most common symptoms of patellar tumor. Range of motion of knee and the force of quadriceps muscle after surgery without patellectomy were better than the surgery of patellectomy. Recurrence was seen in one patella retained case.Conclusion:In our study, chondroblastoma was the most common tumor in patella. Pain and knee effusion were the most common symptoms in patella tumors. Range of motion of knee and the force of quadriceps muscle in patella retaining were better than patellectomy.Key words:Patellar tumors, chondroblastoma, giant cell tumor
