Summary
Peroneal nerve dysfunction can occur after total knee arthroplasty, causing mobility and sensory issues. Surgical decompression improved range of motion and resolved pain in affected patients.
Area of Science:
- Orthopedics
- Neurology
- Surgical Innovation
Background:
- Total knee arthroplasty (TKA) is a common procedure for knee osteoarthritis.
- Postoperative complications can impact patient outcomes and rehabilitation.
- Peroneal nerve dysfunction is an under-recognized complication following TKA.
Observation:
- This study reports on 11 patients experiencing peroneal nerve dysfunction post-TKA.
- Patients presented with either limited range of motion or sensory disturbances.
- Electrodiagnostic testing confirmed dysfunction despite intact motor strength.
Findings:
- Surgical decompression of the peroneal nerve was performed on all 11 patients.
- Patients with motion deficits showed an average improvement of 40° in range of motion.
- All patients with sensory symptoms reported resolution of leg and foot pain.
Implications:
- Peroneal nerve dysfunction should be considered in TKA patients with poor rehabilitation or persistent lateral leg pain.
- Surgical intervention can effectively manage this complication.
- Awareness among orthopedic surgeons is crucial for timely diagnosis and treatment.

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
