| HemiCAP™ Tå (MTP)
The Arthrosurface HemiCAP™ system is a surgical method
for the treatment of localized cartilage lesions and defects
in the major joints. This system is comprised of three elements;
a three-dimensional mapping technology, a set of instruments
to map and prepare the damaged area and a cobalt-chrome and
titanium implant. The CAP™ system precisely aligns the
surface of the implant to the contours of the patient's articular
cartilage surface, thus filling the defect and restoring a
smooth and continuous articular surface. The CAP™ system
has been developed so that it can be utilized via minimal
access surgical techniques.
The HemiCAP™ Instrument Set enables the surgeon to
accurately place the implant and precisely map the curves
of the articular surface, in real-time, under direct or arthroscopic
visualization, with no angle-induced errors or magnification
errors that might exist with MRI, or X-ray imaging techniques.
The HemiCAP™ system is intended to provide an effective
interim means for managing pain and disability in the middle-aged
patient until a total joint replacement treatment option becomes
more necessary, and is part of a clinical treatment strategy
to help avoid early-age-revision scenarios. The prosthetic
may also provide a treatment option for the older patient
who may not tolerate the morbidity of a total joint replacement
procedure.
The HemiCAP™ implants and instruments are designed
to remove a minimal amount of bone stock, preserve functional
structures and tissues, and allow for an uncomplicated removal
in the event of revision.

Introduction
The Arthrosurface HemiCAP™ (Contoured Articular Prosthetic)
Resurfacing System is a surgical method for the treatment
of localized lesions and defects in the major joints. This
system is comprised of three elements; a mapping technique,
a set of instruments to prepare the damaged area and place
the resurfacing prosthesis, and the HemiCAP™ implant.
The CAP™ system precisely aligns the surface of the
implant to the contours of the patient's articular cartilage
surface, thus filling the defect and restoring a smooth and
continuous articular surface. The CAP™ system has been
developed so that it can be utilized via minimal access surgical
techniques.
One component of the HemiCAP™ system is a set of reusable
instruments that are used to map and prepare the defect sites
for receipt of the implant. The HemiCAP™ implants come
in a variety of sizes and curvature profiles designed for
the different surface anatomies. Arthrosurface continues to
design products and development marketing strategies to address
other painful joints of the body.

Description
The HemiCAP™ implant is a rounded, cap-like implant
made from a cobalt chrome alloy with a central post on the
implanted, or bone side. Cobalt chrome is a material that
has been used in total joint reconstruction devices for over
two decades. This material has proven to provide a safe, effective
and strong weight-bearing surface in joints. This metal alloy
exhibits lubricious qualities very similar to articular cartilage
when implanted in a joint. The fixation component that looks
like a screw is made of Titanium, another material that has
been used in Orthopedics for decades.
The HemiCAP™ surgical procedure begins the same way
as all arthroscopic procedures. Two or more small access incisions
are made in order to access the joint. One of the access holes
is used to insert the arthroscope which is like a small telescope.
This is inserted into a cannula or tube which is used to protect
the arthroscope and also allow for a saline fluid to flow
into the joint. The second hole or portal is used to introduce
different instruments during the operation. When an articular
defect is confirmed, the central axis in the middle of the
defect is located and a component that looks like a screw
is implanted to establish the mechanism for anchoring the
resurfacing implant. Using this first component as a central
axis, several specially designed instruments are introduced
to map the contours of the patient's articular cartilage surrounding
the defect and to prepare the tissue in and around the defect
itself for the resurfacing implant. Once the site is prepared,
the HemiCAP™ resurfacing implant is brought into position
and seated.
