New data showed the tibial tubercle was more posteriorly positioned in patients with patellar cartilage lesions compared with patients with intact patellar cartilage.
Researchers retrospectively reviewed 17 patients who underwent patellofemoral cartilage restoration or repair procedures, 20 control patients who underwent partial meniscectomy with normal patellar cartilage and 15 patients with asymptomatic patellar chondrosis who underwent partial meniscectomy with patellar cartilage wear. Preoperative axial They used T2 MRI sequence to measure the sagittal tibial tubercle–trochlear groove (sTTTG) distance. The nadir of the anterior trochlear cartilage was the first point and the second point was the anterior tibial tubercle. Investigators compared the patient groups with analysis of variance testing with Bonferroni corrections.
