Abstract:
A modification of range of motion of the knee can significantly change a patient's quality of life. In general, range of motion of 0° to 125° is adequate for most activities of daily life. The rate of knee arthrofibrosis after ligament reconstruction is reported to be between 0% and 4%; after tibial fracture due to high-energy trauma, the rate is about 7%, with an undetermined incidence after limb lengthening. The purpose of this study was to describe a modification of the operative technique of Judet. We describe minimally invasive quadricepsplasty in 4 steps, aiming to obtain an end result with an arc of movement of at least 120° to 130°. We believe that our technique is a good option for the treatment of the stiff knee, having low morbidity and being an easy method to perform.

Types of Errors: Detection and Minimization
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
