However, the TT-TG distance gives no information about the location of the malformation.<\/jats:p>\n                  <jats:p>Hypothesis: Not all patients with a pathological TT-TG distance (\u226520 mm) had lateralization of the tibial tubercle.<\/jats:p>\n                  <jats:p>Study Design: Cohort study (diagnosis); Level of evidence, 2.<\/jats:p>\n                  <jats:p>Methods: Fifty-eight knees in 49 patients with 2 or more patellar dislocations and 60 knees in 30 volunteers with no history of dislocation were analyzed using magnetic resonance imaging (MRI). The tibial tubercle\u2013posterior cruciate ligament (TT-PCL) distance was defined as the mediolateral distance between the tibial tubercle midpoint and the medial border of the posterior cruciate ligament. The distance was measured parallel to the dorsal aspect of the proximal tibia (dorsal tibia condylar line). Three observers performed the measurements. Significant differences in the TT-PCL distance between the patient and the control group were estimated using an unpaired t test. The inter- and intraobserver variability of the measurement was performed.<\/jats:p>\n                  <jats:p>Results: The intraclass correlation coefficients for inter- and intraobserver variability of the TT-PCL distance were higher than 0.74 and 0.93, respectively. A statistically significant difference ( P &lt; .05) was found between the TT-PCL distance in the control group (mean [SD], 18.4 [3.35] mm) and in patients (21.9 [4.30] mm). The mean (SD) TT-TG was 18.9 (5.16) mm in the patient group and 11.9 (4.67) mm in the control group ( P &lt; .05). In the control group, 95% had a TT-PCL distance &lt;24 mm. In the patient group, 22 of 58 knee joints (38%) had a TT-PCL distance \u226524 mm. Seventeen of 40 knee joints (43%) with a TT-TG distance \u226520 mm had a TT-PCL distance &lt;24 mm.<\/jats:p>\n                  <jats:p>Conclusion: Only 57% of the patients with a pathological TT-TG distance (\u226520 mm) had lateralization of the tibial tubercle in relation to the posterior cruciate ligament. The TT-PCL distance is an alternative method for determining the position of the tibial tubercle.<\/jats:p>","DOI":"10.1177\/0363546512438762","type":"journal-article","created":{"date-parts":[[2012,3,14]],"date-time":"2012-03-14T01:00:32Z","timestamp":1331686832000},"page":"1119-1125","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":268,"title":["Tibial
