Osteoarthritis (OA) - Osteoarthritis (OA) - DefinitionDefinition
Osteoarthritis may result from wear and tear on the joint
•The normal cartilage lining is gradually worn away and the underlying bone is exposed.
![Page 56: Disorders of Lower Limb](https://reader036.vdocuments.us/reader036/viewer/2022070519/58ee14bf1a28ab343a8b4673/html5/thumbnails/56.jpg)
Osteoarthritis (OA) - Osteoarthritis (OA) - DefinitionDefinition•The repair mechanisms of tissue absorption and
synthesis get out of balance and result in osteophyte formation (bone spurs) and bone cysts

Asymmetrical joint space narrowing from loss of articular cartilage
The medial (inside) part of the knee is most commonly affected by osteoarthritis.
OA – Radiographic Diagnosis

OA – Radiographic Diagnosis•Asymmetrical joint space narrowing
•Periarticular sclerosis
•Osteophytes
•Sub-chrondral bone cysts

OA – Arthroscopic Diagnosis
Normal Articular Cartilage
Ostearthritic degenerated cartilage with exposed subchondral bone
Arthroscopy allows earlier diagnosis by demonstrating the more subtle cartilage changes that are not visible on x-ray

•OA is a condition which progresses slowly over a period of many years and cannot be cured•Treatment is directed at decreasing the symptoms of the condition, and slowing the progress of the condition
•Functional treatment goals:•Limit pain•Increase range of motion•Increase muscle strength
OA – Disease Management
![Page 61: Disorders of Lower Limb](https://reader036.vdocuments.us/reader036/viewer/2022070519/58ee14bf1a28ab343a8b4673/html5/thumbnails/61.jpg)
OA – Non-operative Treatments
•Pain medications•Physical therapy•Walking aids•Shock absorption•Re-alignment through orthotics•Limit strain to affected areas

•Osteoarthritis usually affects the inside half (medial compartment) of the knee more often than the outside (lateral compartment).
•This can lead to the lower extremity becoming slightly bowlegged, or in medical terms, a genu varum deformity
Proximal Tibial Osteotomy
![Page 63: Disorders of Lower Limb](https://reader036.vdocuments.us/reader036/viewer/2022070519/58ee14bf1a28ab343a8b4673/html5/thumbnails/63.jpg)
Proximal Tibial Osteotomy•In the procedure to realign the angles, a wedge of bone is removed from the lateral side of the upper tibia.
•A staple or plate and screws are used to hold the bone in place until it heals.
•This converts the extremity from being bow-legged to knock-kneed.
•The Proximal Tibial Osteotomy buys some time before ultimately needing to perform a total knee replacement. The operation probably lasts for 5-7 years if successful.
