Imaging techniques including MR scanning and ultrasound were discussed. However it was noted that for standard orthopaedic practice in the UK plain films were the initial imaging available. The importance of taking a skyline view was stressed. The Dejour protocol was then outlined where the lateral Xray of the knee assesses the patellar height, the presence of dysplasia of the trochlear groove, and, if present, its boss height. A CT scan defines the patellar tilt angle, and with cuts through the tibial tubercle, the offset of the tibial tubercle from the trochlear groove (TTTG). The four abnormalities that can be defined are then corrected at operation. All patients undergo a lateral release. If the patellar tilt angle is greater than 20° then a medial reefing is performed. If the patellar height is greater than 1.2, a distalisation of the tibial tubercle to correct this to 1.0 is done. A MG of greater than 2Omm leads to a correction by an Elmsie medial tubercle transfer. A boss height of greater than 6mm suggests a trochleoplasty should be performed. However the Dejour protocol is yet to be validated. It was concluded that imaging is essential for analysing

Axial radiographs were obtained under valgus and external rotation stress at 45° of knee flexion with and without contraction of the quadriceps muscle in order to assess the dynamics of patellar subluxation or dislocation. The radiography was performed on 82 knees in 61 patients with
Treatment of patellar instability in adolescents is controversial. Some investigators have advocated early repair of the medial structures, whereas others have treated this injury nonoperatively. The medial patellofemoral ligament, is a primary restrictor and stabilizer of the patella, and has acquired a significant role in the treatment of instability in children and adolescents. The authors present a prospective study of 39 consecutive patients (45 knees), without physeal closure, who underwent plasty of the medial patellofemoral ligament for the treatment of symptomatic

Introduction:
The paediatric population present unique challenges to the knee surgeon, particularly when treating recurrent patellofemoral instability(PFI), the management of which is poorly standardised. Through the EPPIC BASK National Trainee Collaborative, we aimed to identify which procedures (and in which combination) are being used to surgically manage recurrent PFI in skeletally immature patients across the UK. A retrospective national service evaluation via a trainee collaborative analysing local trust data between 1st January 2014 and 31st December 2019. Data from institutions registered for EPPIC was compiled and compared to the national guidelines for adults.Abstract

Chronic patello-femoral joint instability leads to recurrent subluxation and dislocation affecting knee function and preventing participation at sport. Traumatic dislocation of the patella results in rupture of the medial patello-femoral ligament (MPFL) in the majority of cases with a high incidence of chronic instability after a second dislocation. MPFL reconstruction can prevent recurrent dislocation and improve knee function. We report on our experience in MPFL reconstruction using hamstring tendons and its effect on the knee function in patients with chronic patello-femoral joint instability. In this prospective study from 2005 to 2008, 68 patients (69 knees) with chronic patello-femoral instability were treated with MPFL reconstruction through a minimally invasive and arthroscopically assisted approach. In this procedure the semintendonosis with or without the gracilis tendon is routed from the pes anserinus to the most distal portion of the medial intramuscular septum before being secured to the superomedial border of the patella. All patients were evaluated pre-operatively and then post-operatively for a mean of 25 months (range 12-48 months). Knee function was assessed by the Tegner, Kujala and Lysholm scores. There were 44 (65%) women and 24 (35%) men. Average age was 27 years. There were 2.7 mean pre-operative patellar dislocations (range 2-7). Mean follow-up was 19.6 months (range 12 to 56 months). IKDC score improved from 48.2 to 74.2, Kujala scores improved from 55.4 to 85.3. Lysholm scores improved from 52.4 to 77.3. Tegner activity scores improved from 2.5 to 5.4. There were overall 87% good to excellent results. No recurrent dislocations or wound related complications. Medial patello-femoral reconstruction can provides excellent results in the treatment of patello-femoral joint instability with poor knee function.
