What is patellofemoral offset?
Changes in patellofemoral joint offset (PFO) refers to a mismatch between the preoperative and postoperative anteroposterior geometry of the patellofemoral joint. It remains unclear whether these changes lead to adverse outcomes in TKA.
What is patellofemoral arthritis?
Description. Patellofemoral arthritis occurs when the articular cartilage along the trochlear groove and on the underside of the patella wears down and becomes inflamed. When cartilage wears away, it becomes frayed and, when the wear is severe, the underlying bone may become exposed.
How long does a patellofemoral replacement last?

What is the treatment for patellofemoral arthritis?
These include adaptations in activity, such as avoiding stairs, limiting squats and lunges, and decreasing impact sports; physical therapy to stretch and strengthen surrounding muscles; and use of medication such as acetaminophen or non-steroidal anti-inflammatory drugs (NSAIDs) to relieve pain.
How long does patellofemoral surgery take?

Are kneecaps removed during knee replacement?

It is sometimes called “runner’s knee” or “jumper’s knee” because it is common in people who participate in sports—particularly females and young adults—but PFPS can occur in nonathletes, as well.
What is isolated patellofemoral arthritis?
Isolated patellofemoral arthritis (IPA) is a debilitating condition characterised by a loss of articular cartilage on the patella facets, the trochlear groove or both.
What is patellofemoral pain syndrome (jumper’s knee)?
It is sometimes called “runner’s knee” or “jumper’s knee” because it is common in people who participate in sports—particularly females and young adults—but patellofemoral pain syndrome can occur in nonathletes, as well. The pain and stiffness it causes can make it difficult to climb stairs, kneel down, and perform other everyday activities.
What are the treatment options for patellofemoral arthritis (PFA)?
