Chapter 5 80 surgical complications, are most relevant to determine post-surgical outcome. This warrants the use of PROMs in this patient category. Third, a difference in the level of preoperative chondropathy between younger and older patients could influence postoperative outcome, but a quantifiable report on the preoperative chondral status is lacking in our study. A lot of patients with patellar luxation or subluxation have some amount of patellofemoral chondropathy, this is inherent to the underlying pathology. It has not been demonstrated that pre-operative chondral status is associated with postoperative outcome. However, a surgeon should be aware of the possible interaction of chondral status and outcome of surgery. Conclusion In this cross-sectional study, pain scores of 113 patients who have undergone a lateral facet elevating trochlear osteotomy for patellar instability were reported. Age at time of surgery was correlated with an increased pain score at rest with an average of 9.5 points (scale 0-100) for every 10 years of age. Age at time of surgery was not correlated with overall satisfaction.
