An adjustable brace was applied with the maximum flexion set at 30°.
We hypothesized that a high-flexion implant design, Scorpio Non-Restrictive Geometry cruciate-retaining knee prosthesis, would allow clinical early maximum flexion of at least 125°.
If the subject has difficulty transferring resistance from one limb to the other, the therapist may assist by stabilizing the seat in the desired cyclocentric zone as the lower limb moves from maximum flexion into extension at the top of the pedal revolution.
The ligament elongations were calculated as the differences in ligament lengths at maximum flexion for PLL, CL, LF, and ISL+SSL and at maximum extension for ALL and MTD, relative to the neutral posture lengths.
We registered the maximum flexion, abduction, internal rotation at 0°, 30°, 60° and 90° of flexion.
Using the compression/distraction unit of the fixator, the fixator was locked at night in maximum flexion and extension alternately.
The wrist and elbow were positioned at joint angles replicating standing position, maximum flexion and extension during normal locomotion, and amplexus (known from Peters and Aulner, 2000), and the muscle lengths were measured between the marker ties.
At 1 year follow-up, the maximum flexion range of knee movement was measured by a physician assistant who was blinded to the study design, using a standard goniometer with the patient in the supine position on a table.
The subject's knee is imaged at nominal 0°, 15°, 30°, 45°, 60°, 75°, 90°, and maximum flexion by adjusting the step height using different numbers of Plexiglas fitted increments, each with a thickness of 19 mm (0.75 inches).
