Osteochondral Allograft Transplant is a possible option for younger patients versus a total knee replacement. A knee allograft is a procedure where cartilage and bone from a cadaver is transplanted into a patient.
Anterior Cruciate Ligament (ACL) Reconstruction
The anterior cruciate ligament is one of the major stabilizing ligaments in the knee. It is a strong rope like structure located in the center of the knee running from the femur to the tibia. When this ligament tears unfortunately it doesn’t heal and often leads to the feeling of instability in the knee.
ACL reconstruction is a commonly performed surgical procedure and with recent advances in arthroscopic surgery can now be performed with minimal incision and low complication rates.

Unicondylar Knee Replacement
This simply means that only a part of the knee joint is replaced through a smaller incision than would normally be used for a total knee replacement. The knee joint is made up of 3 compartments, the patellofemoral and medial and lateral compartments between the femur and tibia (i.e. the long bones of the leg). Often only one of these compartments wears out, usually the medial one. If you have symptoms and X-ray findings suggestive of this then you may be suitable for this procedure.

Revision Knee Replacement
This means that complete or a part of your previous knee replacement needs to be revised. This operation varies from a very minor adjustment to a massive operation replacing significant amount of bone and hence is difficult to describe in full.

The meniscus is a “pad” of cartilage that evens out the distribution of weight on the bones in your knee joints. You have two in each knee.

Articular Cartilage Defect
Damage to the joint surface of the knee is extremely common. The surface of the knee is covered with cartilage – called the articular cartilage. Damage to the articular cartilage can be associated with a traumatic injury such as a motor vehicle accident or athletic injuries but even more commonly occurs spontaneously without associated traumatic causes. In these instances the symptoms can sometimes be confused with those of arthritis.

Anterior Cruciate Ligament (ACL) Tear
The knee joins your upper leg bone (the femur) with the lower leg bone (the tibia) in a joint that’s strong and flexible. Four ligaments hold the two bones in the proper positions relative to one another

Patellofemoral Instability results from one or more dislocations or partial dislocations, also called subluxations. This misalignment can damage the underlying soft structures such as muscles and ligaments that hold the knee in place.

Medial patellofemoral ligament realignment is a surgical procedure indicated in patients with severe patellar instability. Medial patellofemoral ligament is a band of tissue that extends from the femoral medial epicondyle to the superior aspect of the patella.

Arthritis is a general term covering numerous conditions where the joint surface or cartilage wears out. The joint surface is covered by a smooth articular surface that allows pain free movement in the joint. This surface can wear out for a number of reasons; often the definite cause is not known.

Patellar Tendon Tear
Patella tendon rupture is the rupture of the tendon that connects the patella (knee cap) to the top portion of the tibia (shin bone). The patellar tendon works together with the quadriceps muscle and the quadriceps tendon to allow your knee to straighten out.

Quadriceps Tendon Tear
Quadriceps tendon is a thick tissue located at the top of the kneecap. The quadriceps tendon works together with the quadriceps muscles to allow us to straighten our leg. The quadriceps muscles are the muscles located in front of the thigh.

Articular or hyaline cartilage is the tissue lining the surface of the two bones in the knee joint. Cartilage helps the bones move smoothly against each other and can withstand the weight of the body during activities such as running and jumping.

Loose bodies are small loose fragments of cartilage or a bone that float around the joint. The loose bodies can cause pain, swelling, locking and catching of the joint.

Osteonecrosis is a condition in which death of a section of bone occurs because of lack of blood supply to it. It is one of the most common causes of knee pain in older women.

Posterior cruciate ligament (PCL), one of four major ligaments of the knee, is situated at the back of the knee. It connects the thighbone (femur) to the shinbone (tibia).

Posterolateral instability is a condition which occurs when there is damage to the postero-lateral corner, the structures that support the outside of the knee joint. It usually results from injury to the knee ligaments.
