Tibial tubercle advancement osteotomy with bone allograft for patellofemoral arthritis: a retrospective cohort study of 50 knees

摘要

Patients and methods Forty consecutive patients (21 females and 19 males) in a single centre underwent 50 tibial tubercle advancement osteotomy procedures for patellofemoral arthritis between January 1993 and April 2007. Twenty knees with patellar maltracking also underwent medialisation of the tibial tubercle (6–12 mm) in addition to the standard 10–15 mm elevation. Femoral head bone allograft blocks were utilised in all cases, and all patients achieved bony union without further surgery. Forty-five knees had previously undergone arthroscopy, 18 with arthroscopic lateral releases.
