Objective To analyze the application of patellar tendon reconstruction using hamstring tendon in segment resection of the tumor of the proximal tibial and knee replacement of tumor prosthesis. Methods From June 2008 to June2015, 20 patients underwent tumor-type knee prosthesis replacement for the treatment of proximal tibial erosion tumor. The hamstring tendon graft was used for reconstruction of the resected patellar tendon, the medial head of the gastrocnemius muscle was used to cover the prosthesis and reconstruct the patellar tendon, solid reconstruction of knee extension apparatus.The clinic efficacy was evaluated after operation. Results The results of the 20 patients were followed up. The follow-up time was about 12-80 months, average 30 months. Six months after surgery, patients received Enneking knee function evaluation,lower extremity function was excellent in 16 cases, good in 4 cases. The recurrence occurred in one osteosarcoma patient, the recurrence rate was 5%, then the patient was amputed. The patient died in the third follow-up year. No evidence of local recurrence or distant metastasis in other patients was found. There were no infection, peroneal nerve injury and other complications. Conclusion The application of hamstring tendon for patellar tendon reconstruction in segment resection of the tumor of the proximal tibial and tumor-type knee prosthesis replacement can reconstruct knee extensor device very well,which is safe and reliable.
