Posterior Capsular Imbrication for Dynamic Genu Valgum.

Area of Science:

• Orthopaedic Surgery
• Biomechanics

Background:

• Symptomatic genu recurvatum (knee hyperextension >5°) is an uncommon condition causing pain and instability.
• Current treatments include nonoperative management and surgical options like posterior capsular imbrication or tibial osteotomies.
• Posterior capsular imbrication is indicated for genu recurvatum with minimal bony abnormalities, such as posterior tibial slope.

Purpose of the Study:

• To describe a modern arthroscopic technique for posterior capsular imbrication.
• To address the lack of technical and outcome literature on posterior capsular imbrication.

Main Methods:

• Arthroscopic posterior capsular imbrication technique for dynamic genu recurvatum.
• Focus on addressing soft-tissue laxity through capsular tensioning/imbrication.

Main Results:

• The technical note details the steps for performing the arthroscopic procedure.
• Provides a description of the surgical technique for posterior capsular imbrication.

Conclusions:

• Arthroscopic posterior capsular imbrication offers a potential surgical solution for dynamic genu recurvatum.
• Further research is needed to establish the outcomes of this technique.
