[Arthrolysis of the knee joint]

Area of Science:

• Orthopedic surgery
• Biomechanics of the knee joint

Context:

• Extensor rigidity of the knee joint, a condition impacting joint mobility.
• Payr's surgical technique for addressing knee extensor rigidity.

Purpose:

• To evaluate the efficacy of Payr's surgical treatment for knee extensor rigidity.
• To assess the functional outcomes, specifically knee flexion, in patients undergoing this procedure.

Summary:

• Fourteen patients with knee extensor rigidity underwent surgical treatment using Payr's method.
• All patients achieved a knee flexion exceeding 90 degrees post-surgery.
• The study highlights the continued relevance of this surgical approach for appropriate patient candidates.

Impact:

• Demonstrates the effectiveness of Payr's surgical technique in restoring knee function.
• Provides evidence for the value of this intervention in contemporary orthopedic practice.
• Supports the consideration of this procedure for specific patient populations with knee extensor rigidity.
