Final answer:
Secondary complications from genu recurvatum include increased stress on the knee joint, knee pain and instability, and altered gait, which can lead to further joint and soft tissue issues.
Step-by-step explanation:
Genu recurvatum, also known as back knee or hyperextension of the knee, can lead to several secondary complications. Three significant complications include:
- Increased stress on the knee joint, which can exacerbate wear and tear on the articular cartilage, leading to premature osteoarthritis.
- Knee pain and instability, which may result from overstretched ligaments and tendons, affecting the individual's ability to perform daily activities and maintain an active lifestyle.
- Altered gait, as the hyperextension of the knee can cause compensatory changes in the individual's walking pattern, possibly leading to additional stress on other joints and soft tissues, resulting in pain and discomfort in the hips, back, or even the non-affected knee.
Patients with genu recurvatum should engage in physical therapy and possibly use orthotic devices to prevent or manage these complications.
