Mini-invasive Quadriceps-plasty for Severe Flexion-Impeding Knee Stiffness

Area of Science:

• Orthopaedic Surgery
• Biomechanics
• Reconstructive Surgery

Background:

• Severe knee stiffness significantly impacts patient mobility and quality of life.
• Current surgical options for knee stiffness often involve extensive procedures with potential complications.
• A need exists for minimally invasive and effective techniques to address flexion-impeding knee stiffness.

Purpose of the Study:

• To describe a novel mini-invasive quadriceps-plasty technique for treating severe knee stiffness.
• To evaluate the safety and efficacy of this surgical approach.
• To provide a detailed procedural description with video illustration for surgical application.

Main Methods:

• A mini-invasive quadriceps-plasty performed through a small supralateral knee incision.
• Key procedural steps include retinacular and patellofemoral joint release.
• Re-creation of suprapatellar pouch and gutters, overlapping Z-plasty of rectus femoris and vastus intermedius, and vastus lateralis transfer.

Main Results:

• The described mini-invasive quadriceps-plasty was found to be safe and effective in clinical application.
• The technique addresses severe flexion-impeding knee stiffness.
• Detailed description and video illustration enhance surgical understanding and application.

Conclusions:

• The mini-invasive quadriceps-plasty is a viable and effective surgical option for severe knee stiffness.
• This technique offers a less invasive approach compared to traditional methods.
• The detailed presentation facilitates adoption and application by orthopaedic surgeons.
