“…Whereas there are several studies that evaluated the combined reconstruction of the MPFL with a tibial tuberosity transfer or trochleoplasty [1,10,20,23], to our knowledge this is the first study that describes the technique and clinical outcome of a combined femoral derotation osteotomy and anatomical reconstruction of the MPFL in patients with patellofemoral instability and increased femoral anteversion.…”

“…Trochlear dysplasia has been directly associated with both recurrent patellar dislocation [18][19][20] and AKP [21,22] in patients with patellar instability, since it has been observed in 96 % of patients with PF disorders and in only 3 % of controls [15,22]. The surgical correction of trochlear dysplasia is done with the sulcusdeepening trochleoplasty procedure, in which the elevated groove is eliminated and the abnormal sulcus is deepened [23][24][25]; this can also rarely be enriched by the addition of patellar osteotomy in order to achieve a better congruency between the two articulating bones [26]. Some authors have also suggested that trochlear dysplasia may extend more distally to the intercondylar notch and therefore could be more frequent in patients with ACL tears due to a reduced intercondylar notch size that predisposes to ACL injury (Fig.…”

Purpose The purpose of the present epidemiologic study is to record the radiographic presence of trochlear dysplasia and patella alta in patients who undergo anterior cruciate ligament (ACL) reconstruction as a potential underlying factor for postoperative anterior knee pain (AKP). Methods All consecutive cases of skeletally-mature ACLdeficient knees that would undergo ACL reconstruction in three different hospitals were prospectively included during a six-month period. Inclusion criteria were acute and subacute ACL injury with no previous ipsilateral knee operation. Patients with chronic ACL tears, prior-to-ACL-injury history of patellar instability or other PF disorders were excluded from the study. Results A total of 299 knees were included (mean age 32± ten years). Forty-four (14.7 %) knees had a positive 'crossing sign' in the lateral X-rays and 255 (85.3 %) had no sign of trochlear dysplasia (p<0.01). Among the cases with trochlear dysplasia, 41 (93 %) had type A trochlear dysplasia with the presence only of the 'crossing sign' and three (7 %) had type C trochlear dysplasia. Patellar height results included a mean Caton-Deschamps index of 1.0± 0.14 (0.5-1.4). Twenty (6.6 %) knees had an index of less than 0.8, and two (0.6 %) knees had an index less than 0.6. In contrast, 15 (5.0 %) knees had an abnormal value of more than 1.2, indicating patella alta. ConclusionsThe most important finding of the study is the increased prevalence of trochlear dysplasia and patella alta in patients with ACL injury, when compared to the incidence of trochlear dysplasia and patella alta in the general population in the literature. This finding could sound as an alert of a possible additional risk factor for post-operative anterior knee pain after ACL reconstruction.

“…Ntagiopoulos et al followed 27 patients for an average of 7 years after sulcus deepening trochleoplasty for recurrent patellar instability. Sulcus angles decreased from an average of 152°-141° and there were no cases of patellar dislocation following the procedure 66 . At latest follow-up, no patients had radiographic evidence of patellofemoral osteoarthritis and knee pain and function improved significantly from pre-operative meas- Post-operative tibia fracture is also possible following tibial tubercle osteotomy.…”
