“…Further, advances in image acquisition and technology such as image overlapping and dynamic imaging studies (muscle contraction/relaxation, knee extension/flexion) have led to new parameters, such as trochlear dysplasia and tibial tuberosity-trochlear groove distance, along with patellar height, tilt, and deviation. These criteria are utilized to analyze patellofemoral joint morphology and help define abnormal anatomy 2,9,36…”

The purpose of this research was to identify reliable tomographic measurements that can detect patellofemoral abnormality and allow quantification of the risk of patellar dislocation in patients with potential patellar instability. A cross-sectional study in 921 patients with anterior pain or knee instability of at least 6 months’ duration was conducted from July 2001 to December 2009. All subjects were clinically evaluated and underwent radiography and computed tomography of their knees. According to their degree of dislocating patellar dysplasia, the subjects were classified into groups for statistical comparison. There was a statistically significant difference in all measurements when the groups were compared, except for external tibial torsion angle. The most sensitive and specific measurements for determining patellar instability were the trochlear groove angle, tibial tubercle-trochlear groove distance, average patellar tilt, and average patellar height. Patients with potential patellar instability, increased tibial tubercle-trochlear groove distance, and patellar height, tilt, and deviation measurements had a greater risk for patellar dislocation. The clinical relevance of this study is to determine measurements that are able to tell us about patellar dislocation risk.

“…Laxity has been unanimously shown to predispose to recurrent patella dislocation 65 66. In this review it has only been reported in one study23 and was found in 62.5% of patients. A standardised clinical Q angle protocol needs to be established and validated before including this measurement in the assessment of recurrent patellar dislocation.…”

Patellofemoral joint alignment is a major risk factor for recurrent patellar dislocation in children and adolescents: a systematic review

ImportanceThe complex interplay of risk factors that predispose individuals to recurrent patellar dislocation is poorly understood, especially in paediatric patients who exhibit the most severe forms.ObjectiveThe primary aim of this study was to systematically review the current literature to characterise the lower limb alignment, patellofemoral morphology and soft tissue restraints of the patellofemoral joint (PFJ) through medical imaging measurements in paediatric recurrent patellar dislocators and age-matched control participants. The secondary aims were to synthesise the data to stratify the factors that influence PFJ stability and provide recommendations on the assessment and reporting of PFJ parameters in this patient population.Evidence reviewA systematic search was performed using CINAHL, the Cochrane Library, EMBASE, PubMed and Web of Science databases until June 2017. Two authors independently searched for studies that included typical children and adolescents who experienced patellar dislocation and also had direct measures of structural and dynamic risk factors. The methodological quality of the included studies was assessed through a customised version of the Downs and Black checklist. Weighted averages and SDs of measures that have been reported in more than one study were computed. A fixed-effects model was used to estimate the mean differences with 95% CIs regarding the association of recurrent patellar dislocation with patella alta, tibial tuberosity to trochlear groove (TT-TG) distance and bony sulcus angle.Findings20 of 718 articles met the inclusion criteria. Thirty-one risk factors were found; however, only 10 of these measurements had been assessed in multiple articles and only four had both dislocator and control population results. With respect to controls, patients with recurrent patellar dislocations had higher TT-TG distance (p<0.01) and higher bony sulcus angle (p<0.01).Conclusions and relevanceBased on the current scientific literature, increased TT-TG distances and bony sulcus angles predispose children and adolescents to recurrent patellar dislocation. Besides these measurements, studies reporting on recurrent patellar dislocation in children and adolescents should also include characterisation of lower limb alignment in coronal and axial planes and assessment of generalised ligamentous laxity.Level of evidenceSystematic review of prognostic studies, Levels II–IV.

“…There were persistent quadriceps weakness and atrophy present in the operated patients. Aulisa et al 40 reported skeletally immature knees that underwent a lateral release, medial retinacular plication, and Galeazzi semitendinosis hemitransfer through the patella. At a minimum follow-up of 4-years, they found 62% excellent and 38% good results.…”

Knee injuries in the youth athlete

As community-based, organized youth sports have increased in popularity over the last several years, so has the rise of pediatric orthopaedic sports medicine as a subsubspecialty. Although nonsurgical fractures and overuse injuries are seen most commonly, the incidence of surgical injuries, particularly about the knee, is on the rise. This article will review and synthesize recent advances in the treatment of knee disorders resulting from youth sports participation.
