Recession wedge trochleoplasty as an additional procedure in the surgical treatment of patellar instability with major trochlear dysplasia: Early results

Abstract

Recession wedge trochleoplasty is a feasible additional procedure addressing bony trochlear abnormality in the surgical treatment of patellar instability. Our attitude is to perform it never in isolation but associated to realignment of the extensor apparatus according to the à la carte surgery concept. It seems to be effective in preventing future patellar dislocation and reducing anterior knee pain in case of painful patellofemoral instability with a major dysplastic trochlea, or in revision cases when other realignment procedures have failed.

Surgical treatment of patellofemoral instability using trochleoplasty or MPFL reconstruction: a systematic review

“…While all articles defined clear inclusion criteria, only half of them described exclusion criteria [10,15,23,27,29,33,35]. There were different inclusion criteria in most of the studies.…”

Arthroscopic Deepening Trochleoplasty: The Technique

“…3 Based on the these assumptions and our good experience with the ADT, our indications have recently been widened to include patients troubled by chronic AKP, who have not responded positively Adding wobble board and Airex balance, step and lunges. Week [13][14][15][16] Adding NMES with one leg on Bosu balance trainer, pertubation and jogging on trampoline, and crawl.…”

“…This is illustrated by multiple studies in which improvements in patella stability, reduction of anterior knee pain (AKP), and better quality of life have been shown compared with other surgical procedures in cases with severe trochlear dysplasia. [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] The open trochleoplasty is associated with the risk of arthrofibrosis, infection, prolonged pain, and scar formation. 24 With respect to other surgical procedures, the use of minimally invasive surgery has been found to reduce these risks; the same applies to the arthroscopic deepening trochleoplasty (ADT) presented here.…”

Trochleoplasty: Historical Overview and Dejour Technique

“…Beaufils also followed this technique. 9,35 In 2010, David Dejour presented a modification of the "Lyonnaise School" sulcus-deepening trochleoplasty with the combination of soft tissue procedures. 36 This improved surgical technique was the result of the more meticulous analysis of the trochlear dysplasia.…”
