various joint surfaces are lined with
cartilage, which is a very tough, shock
absorbing material. With problems such
as strain, fracture, or osteoarthritis,
they may someday need to be replaced.
The main objective of joint reconstruction
is to replace the injured or worn joint
surfaces with materials such as metal,
plastic, polyethylene, ceramics, or
a combination of those materials. The
material selected depends on the reason
for the surgery, as well as which joint
is being replaced.
At Urquhart Orthopedic Associates,
our surgeons are experts at joint reconstruction,
and employ the latest techniques in
shoulder, hip and knee replacement,
including the minimally invasive
procedures for hip and knee replacement.
Your hip is a ball and socket joint, which
allows bending and straightening of your
body and movement of your lower limbs.
Osteoarthritis is the main reason for
hip replacement surgery, but there are
other conditions, including trauma, which
may require the need for a hip replacement.
Hips and knees are the most commonly replaced
The knee, the largest hinge-type joint
in the body is also one that gets injured
often. Even though major muscle groups,
like hamstrings support your knees, injury
or disease can cause weakness, pain, and
limited function. For many, knee replacement
is the only way to reduce the pain, and
restore function and quality of life.
Your shoulder is a ball-and-socket joint,
and has a greater range of motion than
any other joint in the body. One can hit
a tennis ball and throw a baseball because
of the shoulder’s impressive range
of motion. Injury, arthritis and overuse
can cause degeneration, leading to pain,
weakness and decreased range of motion
of the shoulder. In some patients this
can only be cured with shoulder replacement
Shoulder replacement surgery is much less
common than hip and knee replacements,
as the shoulder is not a weight bearing
joint. Many people are not even aware
that the shoulder can be replaced.
