Sulcus-deepening trochleoplasty with MPFL reconstruction may prevent dislocation
Key takeaways:
- Sulcus-deepening trochleoplasty with medial patellofemoral ligament reconstruction yielded satisfactory results.
- Patients reported improved clinical outcomes. There were low rates of dislocation and arthritis.
Published results showed sulcus-deepening trochleoplasty with adjuvant medial patellofemoral ligament reconstruction may yield positive clinical outcomes with low dislocation rates at long-term follow-up.
David H. Dejour, MD, and colleagues performed a retrospective review of 43 patients (48 knees) who underwent thick-flap sulcus-deepening trochleoplasty with MPFL reconstruction. Mean follow-up was 14.8 years.
Outcome measures included patellar dislocation, IKDC score, Kujala scores and patient satisfaction. Researchers noted four patients (8.3%) were lost to follow-up, leaving a final cohort of 44 knees.
At follow-up, mean IKDC score was 65.7, mean Kujala score was 77.5 and mean patient satisfaction score was 8.2. Researchers found one patient (2%) had a traumatic patellar dislocation that was managed with nonoperative treatment.
Researchers also assessed postoperative radiographs of 34 knees at final follow-up. They found 14 knees (41%) were Iwano grade 1, seven knees (21%) were Iwano grade 2 and 13 knees (38%) had no signs of patellofemoral arthritis.
“Sulcus-deepening trochleoplasty with MPFL reconstruction grants satisfactory results and prevents patellar redislocations with no or minimal patellofemoral arthritis,” the researchers wrote in the study.
