Clinical outcomes of medial patellofemoral ligament reconstruction in patients with an increased tibial tuberosity–trochlear groove distance

Abstract

Case-control study, Level III.

Correlation of the tibial tuberosity–trochlear groove distance with the Q-angle

“…Other authors found significantly elevated TT-TG distances in patients with patellar dislocations [2]. The fact that an elevated TT-TG distance may lead to patellofemoral instability has been clearly proven in the published literature [25,32].…”

Clinical outcome in MPFL reconstruction with and without tuberositas transposition

“…According to Matsushita et al [16], no significant correlations were observed between TT-TG distance and postoperative Kujala. Maybe it can be considered to avoid two cohorts and to test reliability of a single MPFL reconstruction in case of a patella luxation.…”

A prospective randomized trial evaluating two different tensioning techniques for medial patellofemoral ligament reconstruction

“…The patellar height was evaluated by the Insall-Salvati index on the lateral radiographs [11]. The tibial tuberosity to trochlear groove (TT-TG) distance was measured on CT scans [10].…”

“…In the literature, the graft tension was mostly assessed by direct vision via the arthroscopy, and the patella was centered in the trochlear groove during the first 30°of flexion before the final graft fixation [8][9][10]. In our clinical practice, we found that graft tension could be self-balanced well during the range of extension-flexion movements of the knee without the direct arthroscopic view.…”
