Giant cell tumor (GCT) is a benign bone tumor with aggressive characteristics. They are more prevalent in the third decade of life and demonstrate a preference for locating in the epiphyseal region of long bones. They have a high local recurrence rate, which depends on the type of treatment and initial tumor presentation. The risk of lung metastases is around 3%.Between October 2010 and August 2014, nine patients diagnosed with locally advanced GCT or with pathological fracture to the knee level underwent surgical treatment. The aim of this study was to evaluate the results of the treatment, particularly with regard to relapse, and to conduct a literature review.There was a predominance of males (77.7%). The most common location was the distal femur. Four patients (44%) developed local recurrence in the first year after surgery, three in distal femur and one in proximal tibia. Of the two patients with pathologic fracture at diagnosis, one of them presented recurrence after five months.The treatment of GCT is still a challenge. The authors believe that the best treatment method is wide resection and reconstruction of bone defects with non-conventional endoprostheses. Patients should be aware and well informed about the possible complications and functional losses that may occur as a result of the surgical treatment chosen and the need for further surgery in the medium and long term.

Objective: The objective of this study was to perform a functional evaluation of diabetic patients with plantar ulcers using the American Orthopaedic Foot and Ankle Society (AOFAS) score. Methods: In this prospective cohort study, 50 diabetic patients treated in an outpatient clinic under conservative management were consecutively evaluated for active ulcers on the foot. The ulcer mean progression time, size and classification and the AOFAS score were evaluated. Results: Among the sample, 38 (76%) were men, the mean age was 64 years, and the mean body mass index was 28.27 kg/m2. The mean ulcer progression time was 9 months, and 40 (80%) patients were classified as Wagner grade 1. There was a significant difference in AOFAS scoresbetween ulcer grades. Conclusion: The AOFAS score can be used for functional evaluation in diabetic patients with ulcers. However, due to the peculiarities of this population, it is important to search for new and more comprehensive evaluation instruments. Level of Evidence II; Prognostic Studies; Prospective Study.
