Table 3 - Anatomic Studies in Total Knee Arthroplasty
Nerve Study At Risk Maneuver Study Finding
Saphenous Nerve Lee et al37 Anterior Arthrotomy Average distance superior to tibial tubercle 16.82 mm
Tanavalee et al40 Midline vs MIS arthrotomy
No difference in ability to avoid inferior branch of the saphenous nerve with either strategy given its position.
Common Peroneal Nerve
Sankineani et al33 Posterolateral Corner Inside Out Release
7.8 - 26.2 mm from posterolateral capsule.
Yang et al34 Posterolateral Corner Inside Out Release
11.76 - 21.2 mm from the tibia and no difference between valgus aligned knees or neutral aligned knees.
Tibial Nerve Chinnappa et al36 Stretch Mean lengthening was 3.5 mm in TKA series with no nerve injuries in 91 cases.
Kerns et al23 Stretch Tibial nerve more tolerant of stretch injury with higher loads to failure. Likely why TN injury occurs with CPN injury.
