OrthAlign, Inc. is committed to providing orthopedic
surgeons with user-friendly, cost-effective, surgical
navigation products for precise alignment. The KneeAlign™
system provides the surgeon with simple, precise tibial
resection for total knee arthroplasty (TKA). This cut is
often described as the foundation for a successful TKA,
and tibial malalignment, in
particular, has been associated with increased risk of
implant failure and revision surgery.3
For the past decade, the principal alternative to
conventional instrumentation in TKA has been large
console computer-assisted surgery (CAS) systems. These
CAS systems have been shown to significantly improve TKA
alignment results, with a recent meta-analysis of data
from 29 randomized clinical trials finding that 9% of
TKAs performed with CAS resulted in mechanical axis
malalignment of greater than 3º vs. a 31.8% outlier rate
for TKAs performed using conventional instrumentation.4
However, only about 3% of TKAs are performed using CAS
in the United States.5 There are a number of reasons why
orthopedic surgeons have not adopted CAS, including its
extended learning curves, longer average procedure
times and high capital costs.
The KneeAlign™ system is designed to fit within the
surgeon's current technique, helping to ensure that the
operation proceeds quickly and efficiently. In addition,
the KneeAlign™ system requires no capital expenditures
and, based on clinical experience, entails only a short
learning curve, allowing the surgeon and hospital to
quickly evaluate the system at minimal cost.
