Modified Medial Collateral Ligament Indentation Technique in Total Knee
Arthroplasty with Severe Type II Valgus Deformity

Endorsed by: Dr. Samir Babaria, Orthopedic Surgeon, Ahmedabad

Introduction
Valgus deformities are reported in around 10% of patients with end-stage arthropathy who have
undergone total knee arthroplasty (TKA). 1,2

Valgus deformities have been classified into three types by Krackow. Type II valgus deformity
3
involves medial soft tissue laxity such that the deformity cannot be completely corrected. Thus,
3
treatment of patients with type II valgus deformities is complex and may involve multiple
reconstructive options to address the soft tissue imbalance. 3,4

The present study assessed the clinical outcomes of a modified technique for indentation of the
medial collateral ligament (MCLI), and compared with the traditional lateral structures release (LSR)

surgical approach for any significant benefit. 4

Methods

This study retrospectively enrolled 43 patients Krackow type II valgus deformity of >20°

from May 2008 to June 2017. Patients were flexion

included in the study based on the following
criteria : (iii) underwent unilateral primary TKA
