to monitor brain health long term and
help determine the effectiveness of dif-
ferent therapies.
Quadrant Biosciences has partnered
with the Hall of Fame (HOF) Players
Foundation to monitor the brain health
of retired National Football League ath-
letes using the toolkit. As part of contin-
ued concussion research, the company
is also collecting saliva samples to mon-
itor for epigenetic biomarkers.
Testing began in April 2018 with new
participants being added in August.
Complications around the perineal post
and current boot technology in hip
arthroscopy include nerve dysfunction
symptoms and problems in the groin
area have long bedeviled sports medi-
cine physicians.
Dipmann et al. published in Arthros-
copy in 2014 found 46% of hip arthros-
copy patients reported nerve dysfunc-
tion symptoms. In addition, 22% still
reported symptoms after 26 weeks and
18% still reported symptoms after one
year. And Frandsen et al. published in

the Journal of Hip Preservation Surgery in
2017 found 32% of patients reported
problems in groin area.
The problems were temporary and dis-
appeared typically within two to four
weeks. Some patients reported numb-
ness after two months.
Now Stryker has developed a very novel
system which reduces groin complica-
tions, minimizes heel slip, and improves
range of motion for hip arthroscopy.
It also gives surgeons better visibil-
ity, allowing them to see and do more
which also improves patient outcomes.
A recent study of 1,000 hip arthros-
copies performed without the use of a
perineal post found in every case that
the procedure allows safe, adequate,
reproducible access to the hip joint
without groin-related soft tissue or
nerve complications. The study was
published in March of 2018 in The
American Journal of Sports Medicine.
Patent filings occurred between 2015
and 2018. ♦
