Maquet osteotomy for chondromalacia patellae: avoiding the pitfalls

Area of Science:

• Orthopedic Surgery
• Biomechanics
• Knee Joint Anatomy

Background:

• The classic Maquet procedure aims to reduce patellofemoral joint pressure.
• Previous surgical interventions for patellofemoral issues can result in complications or treatment failure.
• Patellofemoral joint decompression is crucial for managing knee pain and dysfunction.

Purpose of the Study:

• To evaluate the efficacy of a modified Maquet procedure for anterior tibial tubercle displacement.
• To assess the safety and complication rates associated with the modified Maquet technique.
• To determine the outcomes of this modified procedure in patients with prior failed knee surgeries.

Main Methods:

• A modified Maquet procedure involving anterior tibial tubercle displacement was performed.
• Forty-four patients were included: 20 retrospectively and 24 prospectively.
• Prospective patients included those with prior failed Hauser operations, patellectomy, proximal realignment, or patellar shaving.

Main Results:

• The modified Maquet procedure effectively decompressed the patellofemoral joint.
• Strict adherence to the technique prevented all major complications.
• Excellent results were observed in nine patients who underwent the procedure after a failed Hauser operation, attributed to reduced patellofemoral compression.

Conclusions:

• The modified Maquet procedure offers an effective solution for patellofemoral joint decompression.
• This technique demonstrates a low complication rate when performed with strict adherence.
• The modified Maquet procedure is a valuable option for patients with persistent patellofemoral issues, including those with prior surgical failures.
