Objective: The paper is intended to analyze and evaluate the specific clinical effects of patients who suffered from invasive bone tumors at proximal tibia and received the rotating-hinge knee prosthesis replacement.

Method: 1,000 cases of patients with invasive bone tumors at proximal tibia all received the treatment of rotating-hinge knee prosthesis replacement. After the operation, the 4-year follow-up visit was conducted on these patients to understand knee joint recovery, complication incidence rate and illness recurrence rate etc. for an evaluation of the treatment effects.

Results: The average time of follow-up visit was 4.1 ± 0.5 years and 837 patients recovered well. The clinical score system of osteoclastoma showed that the average score was above 3 with the overall effective treatment rate at 83.7%. 163 patients suffered from illness recurrence with the recurrence rate at 16.3%, and 97 (9.7%) patients suffered from complications during the post-operation recovery with the average knee joint flexion at (95.5 ± 2.4)° and straightening knee joint flexion up to 180°.

Conclusion: Good treatment effects are achieved among patients who suffered from invasive bone tumors at proximal tibia and received the rotating-hinge knee prosthesis replacement, and the treatment is beneficial to the knee joint functions and normal limb movement.
