Tibial Tuberosity Anteromedialization for Patellofemoral Chondral Disease
2017
Background:Tibial tuberosity anteromedialization (TTA) is a well-established treatment option for patellofemoral chondral disease that is resistant to nonoperative treatment. However, the prognostic factors of this procedure are unknown.Purpose:To analyze the prognostic factors correlated with the midterm outcomes of TTA for patellofemoral chondral disease and determine the survivorship.Study Design:Case series; Level of evidence, 4.Methods:Indications of TTA for chondral disease included skeletal maturity, age <65 years, lateral release, and (3) minimum 2-year follow-up. Exclusion criteria were (1) previous knee surgeries, (2) previous patellar dislocations, (3) inflammatory/rheumatic conditions, (4) major combined procedures other than lateral release, (5) focal chondral lesions amenable to cartilage r...
