Treatment of knee stiffness after tibial plateau fractures according to its chronicity.

	Duration of stiffness
	<3 months	3–6 months	>6 months
Treatment	MUA	Arthroscopic release	Open release
Considerations	Some authors routinely associate it with arthroscopic release.	Some authors propose it with a shorter evolution time.	Assess the type of stiffness (flexion/extension) to decide the adequate surgical technique.
		Some authors associate endoscopic extra-articular quadriceps release or pie-crusting.
