Summary
Snapping pes syndrome is rare at the knee but can occur after total knee arthroplasty. Residual bony prominences or alignment changes post-surgery may cause these snapping symptoms.
Area of Science:
- Orthopedic Surgery
- Biomechanics
Background:
- Snapping syndrome, characterized by audible or palpable snapping, is uncommon at the knee joint.
- Pes anserinus bursitis and tendinopathy are common causes of snapping in the general population.
Purpose of the Study:
- To report the first known case of snapping pes syndrome following total knee arthroplasty (TKA).
- To highlight potential etiologies of this rare complication after TKA.
Main Methods:
- Case report detailing clinical presentation and diagnostic findings.
- Review of relevant literature on snapping knee and TKA complications.
Main Results:
- A patient developed snapping pes syndrome after undergoing TKA.
- The snapping was attributed to a residual bony prominence and altered limb alignment post-surgery.
Conclusions:
- Snapping pes syndrome is a rare but possible complication after TKA.
- Surgeons should consider residual bony irregularities and changes in alignment as potential causes of snapping symptoms in TKA patients.
