Keblish's lateral subvastus approach for total knee arthroplasty: A technical note.

Abstract

Keblish's lateral surgical approach for total knee arthroplasty enables a direct release of the lateral structures in valgus deformities. In recent years, the development of quadriceps-sparing techniques has improved early functional recovery after arthroplasty, which has been well described using a medial approach. The authors present Keblish's lateral subvastus approach for genu valgum deformities, with key surgical considerations and preliminary outcomes. The novelty of this technique lies in its combination of a lateral subvastus approach with Keblish's Z-plasty, aiming to optimize quadriceps recovery while ensuring secure knee closure following valgus deformity correction. The Keblish's lateral subvastus approach provided adequate surgical exposure without any observed complications in this small short follow-up series, allowing for early recovery of active knee extension and satisfactory clinical outcomes.
