Abstract: The present invention discloses a renovated titanium mesh used for repairing bone defects in knee joint replacement. The renovated titanium mesh (1) includes transverse ribs (2) for implanting the renovated titanium mesh into a human body and longitudinal ribs (3) for supporting the transverse ribs (2). The transverse ribs (2) and the longitudinal ribs (3) are crisscrossed to form the meshed renovated titanium mesh (1). In the renovated titanium mesh of the present invention, the meshed structure of the renovated titanium mesh can ensure the bone ingrowth of a patient, and the renovated titanium mesh can be cut to provide a high degree of matching for the patient and to thus satisfy the patient's demand; the renovated titanium mesh can better ensure the bone ingrowth of the patient and be advantageous for the later recovery of the patient.
