Age at the Time of Surgery Does Not Compromise the Outcome of Deepening Trochleoplasty: Results from Under- and Over 30-Years-Olds: Patellofemoral

Key Points

To evaluate the influence of age at surgery on patient-reported outcomes in individuals undergoing deepening trochleoplasty for recurrent lateral patellar dislocation.
Retrospective cohort study using prospectively maintained database.
Assessment of patient-reported outcomes with BPII 2.0 and NAS for pain and knee function.
Comparison between patients ≥30 years and <30 years, evaluating data at mean follow-up of 30-33 months post-surgery.
Both age groups showed significant improvement in patient-reported outcomes with BPII 2.0 (p<0.0001).
No significant difference in outcomes for patients ≥30 years vs. <30 years (final follow-up p=0.24).
High percentage of patients in both groups achieved minimum clinically important difference of 10 points (88.2% SG vs. 89.7% CG, p=0.99).

Abstract

Objectives: Lateral patellar dislocation (LPD) typically occurs in the young and active population but might also affect patients over 30 years of age. Conflicting reports regarding the influence of age at the time of surgery and postoperative patient-reported outcome measures (PROMs) have been reported. Therefore, this study aimed to evaluate whether age at the time of surgery influences patient-reported outcomes (PROMs) in individuals undergoing tailored surgical treatment for recurrent LPD, including deepening trochleoplasty (TP). We hypothesized that patients ≥30 years would achieve PROMs comparable to those 0.1). The AMADEUS scores were 80.1 ± 15 points (CG) and 82.1 ± 14.2 points (SG) (p=0.57), respectively. No correlation was found for ‘AMADEUS’ and postoperative BPII 2.0 scores (p= 0.19; r2= 0.01) Conclusion: Deepening TP, as part of a tailored surgical treatment plan for recurrent LPD, yielded satisfying results, irrespective of patient age at the time of surgery.
