Beyond the above-listed more commonly encountered complications associated with trochleoplasty procedures, postoperative superficial wound complications have been reported [37]. Given the intra-articular nature of the procedure and potential fixation devices used for trochleoplasty flap reduction, hardware removal has been reported in the literature as well [31, 32]. Continued patellar instability and increased pain from baseline have also been reported from the potential over- or under-correction resulting in patellar incongruence [38, 39] at the time of surgery.
