Abstract: Objective 　To evaluate different choices of the surgical approach to recurrent giant cell tumors of bone. Methods 　In the recent 3 years, 23 cases of recurrent giant cell tumor were overviewed ret ropectively. The recurrence rate and the function of adjiacent joint were analyzed. Results 　In this series, 7 cases had curettage, 13 cases had wide resection and 3 cases had amputation. All patients had been followed up for a meantime of 26. 5 months. There were only 1 case of recurrence with lung metatasis and 1 case of death. In the wide resection group, 10 cases were reconst ruced with prosthetic replacement, and 2 cases with allograft . The enneking functional score of curettage group, prosthetic replacement group and allograf t group were 29. 8, 25. 2 and 22 respectively. There had statistically difference between curettage group and allograf t group ( P < 0. 05) . Conclusion 　In recurrent giant cell tumors of bone, curet tage method was recommended firstly. If there had any anti-index of curretage, lesions around the knee should be treated with wide resection and prosthetic replacement, and lesions around the wrist should be t reated with wide resection and allograft with or without arthrodesis. Lesions located in the pelvis and sacrum should be treated with wide resection.
