QID 3150 (Type "3150" in App Search)
A 65-year-old male undergoes a primary total knee arthroplasty. His preoperative radiographs are seen in figures A and B. Postoperative examination reveals an inability to dorsiflex his ankle or extend his toes. Sensation is decreased along the dorsum of his foot as well as between the 1st and 2nd toes. All of the following are risk factors for this complication following total knee arthroplasty EXCEPT?

Peroneal nerve palsy following a total knee arthroplasty has been shown to be associated with postoperative epidural analgesia, correction of large valgus deformities, and preoperative diagnosis of neuropathy in the involved extremity (either centrally or peripherally). One may also sustain peroneal nerve palsies following aberrant retractor placement intraoperatively.

Idusuyi et al performed a retrospective review and found a significant increase in the relative risk of developing a peroneal nerve palsy following total knee arthroplasty in patients who received postoperative epidural analgesia, had prior lumbar laminectomies, and had preoperative valgus deformities of greater than 12 degrees.

The review by Nercessian et al discusses the above risk factors, treatments and prognosis of a peroneal nerve palsy following total knee arthroplasty. Most studies in this review demonstrated approximately 50% complete recovery with a higher likelihood of complete recovery associated with a less severe initial injury. The time to recovery ranged from 18 months to 5 years, and while nerve exploration was seen to help in a small group of patients, this treatment modality remains controversial.
