The Brisbane Orthopaedic and Sports Medicine Centre Knee Service
is comprised of a team of orthopaedic surgeons with a subspecialty
in knee surgery who develop a treatment plan tailored to each
individual patient’s
needs. The Centre
provides comprehensive orthopaedic services for all conditions of
the knee including
anterior cruciate ligament (ACL) reconstruction, cartilage repair,
chondromalacia and knee
arthroscopy.
The Centre's Knee Orthopaedic Physicians
Services Offered
The Centre offers a wide range of expertise and
treatment options. We specialise in both open and arthroscopic surgery.
The most common types
of surgery performed are anterior cruciate ligament (ACL) reconstruction,
cartilage repair, arthroscopic knee surgery and surgical replacement
of the knee joint.
- Anterior Cruciate Ligament (ACL) Reconstruction - The
anterior cruciate ligament (ACL) is one of four stabilising ligaments
of the knee. It prevents abnormal anterior displacement and
rotation
of the lower leg. The ACL may be injured with excessive pivoting or
twisting of the knee as well as hyperextension, hyperflexion or lateral
trauma
to the knee. When the ACL is torn, the patient may hear or feel a "pop" in
the knee, followed by swelling and difficulty continuing their activity.
The patient may have a hard time walking and may also feel a sense
of instability. An ACL tear is best diagnosed in a physical examination
by an orthopaedic physician. An MRI (magnetic resonance image) may
be obtained to confirm an ACL tear, as well as identify injury to other
parts of
the knee.
- Cartilage Repair - For knee joints to function properly,
the knee requires a smooth gliding articular cartilage surface on the
ends of the bones. This
surface is
composed of a thin layer of slippery, tough tissue called hyaline cartilage.
This cartilage acts to distribute force during repetitive pounding-like
movements, such as jumping or running. A knee injury can cause cartilage
lesions or locking, which can cause localized pain hindering movement
and causing further deterioration of the joint surface.
- Chondromalacia - Chondromalacia patellae is a painful
disorder of the knee, most commonly affecting adolescents, in which
the cartilage directly behind the kneecap
is damaged. When it occurs in adults it is known as retropatellar
arthritis. The cause is uncertain. Pain is felt when the knee is straightened
and is particularly bad when running, jumping, climbing or descending
stairs.
Most orthopaedic surgeons agree that chondromalacia should first
be
treated conservatively.
- Knee Arthroscopy - Arthroscopy is a surgical technique
whereby a tube-like instrument is inserted into a joint to inspect,
diagnose and repair tissues.
- Meniscal Tears - The meniscus is a crescent-shaped
disk of cartilaginous tissue found in several joints in the body. The
knee joint has two, and is held
in place with ligaments. Their main function is to reduce friction
during
joint movement. Meniscal tears are most commonly caused by twisting
or hyperflexion of the joint. In many cases, using proper techniques
while
exercising or playing sports may be able to prevent a meniscal tear.
When a tear occurs there is usually a "pop" noted at the
time of injury, followed by joint tenderness and knee pain. Recurrent
knee
catching is also a symptom. A physical examination, x-rays and MRI
are tests available to determine a meniscus tear. Treatment may include
ice,
anti-inflammatory medication and physiotherapy. For very active
patients, surgery may be indicated.
