Patients with Krackow type II valgus
deformity >20° who underwent a
primary unilateral TKA

MCLI LSR
20 patients 23 patients

Radiological parameters
Valgus angle (VA)

Clinical assessments were done:
Preoperatively Thickness of the
Postoperatively polyethylene insert
(3 months, 1 year, and
annually thereafter)
Functional outcomes

Results Implant Evaluation

The mean follow-up period of the study was
62.4 months. 4 The MCLI group compared to the LSR group
used :
4
Significant improvement in deformity and pain thinner polyethylene inserts
in all the patients was reported. 4 fewer number of constrained condylar inserts

Table 2: Assessment of use of implants in MCLI and LSR
No statistically significant differences were groups 4
recorded in preoperative (KSS t = 0.481, P =

0.752; KSF t = 0.392, P = 0.631) or
postoperative (KSS t = 0.449, P = 0.930; KSF t MCLI LSR
= 0.143, P = 0.782) patient outcome scores
