Nonresorbable suture tape (FiberTape<jats:sup>\u00ae<\/jats:sup>, FT) is possibly becoming an option to tendon grafts for MPFL\u2010R. Patella\u2010side fixation of FT can be performed with suture anchors or via soft\u2010tissue fixation. The aim of this study was to investigate patellar tracking considering soft\u2010tissue\u2010based and anchor\u2010based patella\u2010side fixation techniques.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In eight fresh\u2010frozen human knee joint specimens (m\/f 4\/4; age 75\u2009\u00b1\u200910 years), the MPFL was identified, and a rupture was placed near the femoral insertion site. In the study group (SG; 4\u00a0knees), soft\u2010tissue fixation of the FT was performed at the medial patellar retinaculum; in the control group (CG; 4\u00a0knees), FT was fixed at the patella via suture anchors. For native MPFL (nMPFL), ruptured (\u201cinjured\u201d) MPFL (iMPFL) and reconstructed MPFL (FT\u2010MPFL\u2010SG, respectively, FT\u2010MPFL\u2010CG) cone beam CT scans were performed in 15\u00b0, 30\u00b0, and 45\u00b0 of knee joint flexion. Patellar tracking was assessed using the radiological parameters patellar tilt (PT), congruence angle (CA) and posterior patellar edge\u2010trochlear groove ratio (PTR).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>All recorded radiological parameters increased, respectively, decreased in the CG and SG from the nMPFL to the iMPFL state.

All investigated parameters of patellotrochlear alignment were positively, respectively, negatively significantly (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05) correlated throughout all evaluated conditions (nMPFL, iMPFL, FT\u2010MPFL\u2010SG, FT\u2010MPFL\u2010CG).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>MPFL\u2010R with a nonresorbable suture tape can normalize patellar maltracking in fresh\u2010frozen human knee joint specimens in earlier degrees of knee joint flexion independent of patella\u2010side fixation technique.
