NexGen® Complete Knee Solution Cruciate Retaining Augmentable Knee (CRA)
The NexGen CRA, a cruciate retaining implant, is intended for patients who,
in the physician's judgement, have adequate bone stock and whose ligaments
provide adequate joint stability but may require augmentation or stem
extensions for fixation or bone loss compensation. The CRA is frequently
used for patients undergoing "revision" or surgery for replacement of an
existing knee joint. The CRA is designed to help accommodate people with the
ability and desire to perform activities that require at least 0-120 degrees
of flexion such as, walking, sitting, and climbing stairs.NexGen CRA Case Study
The x-rays shown are from a 79-year-old male, candidate for revision total
knee replacement surgery, who had symptoms of night pain, severe pain when
walking or climbing stairs, and difficulty in bending activities. Range of
motion preoperatively was 0-95 degrees and his ligaments were stable.
Postoperatively, the patient recovered well and had a range of motion
after rehabilitation of 0-111 degrees. Note: This case study represents
the outcome of only one patient and results may vary.
