The patient progresses to full range of motion from 6-12 wk. |
The patient should have full range of motion by 12 wk. |
Brace wear |
The patient wears a hinged knee brace locked in extension for the first 2 wk except when performing range-of-motion exercises. |
An unlocked hinged knee brace is worn during the day after 2 wk. The patient keeps the brace locked in extension at night for the first 6 wk. |
Bracing is discontinued at 6 wk. |
Exercises |
The patient may do heel slides, quadriceps sets, straight-leg raises, and hamstring and calf stretching for the first 6 wk. |
