“…Thus, 77% were satisfied with the procedure. Donnel et al [13] described 15 patients (17 knees) who underwent deepening trochleoplasty with a mean follow-up of three years. Trochleoplasty was indicated if there was a boss greater than 6 mm, and associated procedures were performed as required.…”

Sulcus deepening trochleoplasty is a technically demanding procedure with precise indications: high grade trochlear dysplasia with patellar instability and/or abnormal tracking. The main goal is to decrease the prominence of the trochlea and to create a new groove with normal depth, thus optimising patellar tracking. Associated abnormalities should be specifically treated. Recurrence of instability is very rare after this procedure and is more likely to result from missed associated abnormalities. Although results seem very good in terms of instability, further evidence is still needed since the groups of patients in the published series are heterogeneous. Trochleoplasty is not indicated for patellofemoral arthritis or pain. As any surgical procedure, sulcus deepening trochleoplasty is liable to complications.

“…A considerable number of causes for patellar instability such as trochlear dysplasia, MPFL insufficiency, increased Q-angle, patella alta, an increased tibial tuberosity-trochlear groove (TT-TG) distance, VMO weakness or valgus alignment have been described [5][6][7]. In the last decades, an increasing number of surgical procedures have been…”

“…Trochlear dysplasia is considered to be one of the most relevant factors of patellar instability [2,5,[7][8][9][10][11][12]. To date, trochlear dysplasia has been defined as a flat, articular zone of variable length, which is situated proximally and is associated with a shallow groove distally [2].…”

The central trochlea has been considered as the major location of dysplasia. The purpose of this study was to investigate the influence of the lateral trochlea on patellar stability and to establish a new method for measuring the lateral trochlea on sagittal magnetic resonance (MR) images. Twenty-eight knees of 23 patients suffering from lateral patellar subluxation (12 knees with radiological signs of central trochlear dysplasia) and of 46 patients without patellofemoral complaints (without central trochlear dysplasia) were analysed. The lateral condyle index was designed to measure the lateral trochlea by comparing the anterior cartilaginous trochlea (a) and the posterior aspect (p) [(a:p)× 100]. The lateral condyle index showed high interrater reliability (r=.94) and was significantly (p<0.001) lower in symptomatic patients (86%) than in the control group (93%). These results show high clinical relevance of the lateral trochlea as another factor for patellar instability.
