Key Takeaways:
Knock knees (valgus) and bow legs (varus) are conditions that affect the alignment of the legs, typically resulting from knee problems such as arthritis.
Knee replacement surgery can significantly improve leg alignment, helping to distribute weight more evenly across the knee joint.
While knee replacement can typically correct angulation that has developed due to arthritis, very extreme cases may not be fully corrected.
Leg alignment issues like knock knees or bow legs can also increase the risk of developing osteoarthritis due to uneven wear and tear on the knee joint.
Prior to surgery, consultation with a healthcare provider is crucial to assess the severity of your condition and discuss potential benefits and risks.
Knee Replacement for Knock Knees and Bow Legs
A common question that arises in the orthopedic field is whether knee replacement surgery can correct leg alignment issues like knock knees or bow legs. This article aims to delve into these conditions, how they are caused and the role of knee replacement in treating them.
What are Knock Knees?
Knock knees, medically known as genu valgum (valgus deformity), is a condition where the knees angle in towards one another and may touch each other when the legs are straightened. Individuals with knock knees have a distinct space between their feet and ankles when they stand. This condition is common during development in children and usually corrects itself as they grow. However, in some adults, it can persist or develop due to obesity, arthritis or injury.
What are Bow Legs?
On the other hand, bow legs, or genu varum (varus deformity), is a condition where the knees bow outwards, creating a noticeable gap between the knees when the feet are placed together. It's common at an early age in children up to the age of 3. In adults, it can occur due to conditions such as rickets, Blount’s disease or as a result of arthritis in the knee.
The Role of Knee Replacement Surgery in Correcting Leg Alignment
Knee replacement surgery, also known as knee arthroplasty, can play a significant role in correcting leg alignment problems caused by arthritis. During the procedure, the surgeon can adjust the alignment of the leg to straighten it out. This adjustment aims to distribute weight more evenly across the knee joint which can help to alleviate pain and improve function.
However, it's important to note that the extent of the correction is dependent on the severity of the angulation. While knee replacement can typically improve any angulation that has developed over time due to arthritis, it may not fully correct extreme cases of knock knees or bow legs. Still, significant improvement is usually achievable.
The Impact of Leg Alignment on Knee Health
Having knock knees or bow legs can put extra stress on certain parts of the knee joint, increasing the risk of developing osteoarthritis over time. This abnormal alignment can lead to uneven wear and tear on the joint, causing pain, stiffness and functional impairment. Therefore, correcting the alignment of the leg through knee replacement surgery not only improves the appearance of the legs but also contributes to better knee health.
Consultation and Assessment Prior to Surgery
Before deciding on knee replacement surgery, it's crucial to consult with a healthcare provider. They will assess the severity of your condition, consider your overall health and discuss with you both the potential benefits and risks of the surgery. This consultation is an essential step in ensuring the most appropriate treatment for your specific situation.
While knee replacement surgery may not be able to fully correct extreme cases of knock knees or bow legs, it can significantly improve the alignment of the legs in many cases. This improvement can lead to reduced pain, improved function and better overall knee health.
