“…More specifically, PF arthritis presents constantly with AKP, and other authors have documented that patients with established PF arthritis that required surgical treatment had a history of significantly higher AKP than controls (22 % vs 6 %, p<0.001) [48]. The risk of long-term arthritis after ACL reconstruction has been questioned in the literature, and the possibility of PF arthritis following ACL reconstruction has been recently re-emphasized [49][50][51].…”

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.

“…[11] Furthermore, it is plausible that AKP in adults may precede the development of osteoarthritis in later years. [12] Despite its prevalence, chronicity and impact, AKP remains one of the most challenging musculoskeletal conditions managed by practitioners. [13] Since greater pain severity and longer symptom duration are predictive of poor prognosis, [14] early effective management may be the key to limiting the longer-term impact of the condition.…”

INTrOdUçãOA instabilidade fêmoro-patelar é ainda um grande desafio para o ortopedista, não havendo consenso sobre a melhor abordagem, se conservadora ou cirúrgica (1,2) e, nos casos de indicação cirúrgica, qual a melhor técnica a ser empregada. Aquelas que envolvem a liberação do retináculo lateral associada à plastia do vasto medial são denominadas realinhamento proximal (3,4) e podem ser realizadas por via aberta ou fechada (artroscópica) (5) . As que utilizam procedimentos ósseos sobre a tuberosidade tibial anterior, com o intuito de melhorar a biomecânica articular, são denominadas realinhamento distal (4,6) (Figura 1).Dejour et al (7) considerou quatro fatores predisponentes à luxação: displasia troclear, inclinação lateral da patela, interpretada como displasia do vasto medial oblíquo, patela alta e lateralização da tuberosidade tibial anterior (aumento do ângulo "Q"). Nas últimas décadas, tem sido dada maior importância ao ligamento fêmoro-patelar medial como estabilizador articular, sendo seu reparo descrito principalmente nos casos de luxação traumática e na ausência de fatores predisponentes (8,9) . Outros procedimentos cirúrgicos a ser considerados, porém em situações de exceção, são as trocleoplastias e as patelectomias parciais ou totais (8) .Didaticamente, podem-se dividir as instabilidades crônicas fêmoro-patelares em quatro grupos: as instabilidades maiores (luxação habitual e inveterada), instabilidades objetivas (luxação recidivante e traumática), instabilidade potencial e artrose fêmoro-patelar (1,6,7) .
