| Summary: | Introduction: Habitual patellar dislocation is rare. This study shares insights from a case series and surgical technique description. Method: ology: Four patients with habitual patellar dislocation were treated using the INTERVALCUT technique, including medial patellofemoral and patellotibial ligament reconstruction, and the Roux-Goldthwait procedure. Kujala, Lysholm, and KOOS scores were evaluated during follow-up. Results: With an average follow-up of 8.51 years, significant improvements were noted in all scores. Two patients with dislocation <20° required proximal release for severe shortening, while two with dislocation at 20–35° stabilized with three-interval releases. No major complications occurred, and all patients achieved functional recovery. Discussion: The INTERVALCUT technique addresses both proximal and distal extensor mechanism segments, surpassing limitations of traditional techniques focused on distal releases. This comprehensive approach minimizes fibrosis and extension deficits, enabling better recovery. Conclusion: INTERVALCUT is a safe, effective, and customizable technique for managing habitual patellar dislocation in flexion, offering excellent functional outcomes and low complication rates. |
