Knee Dislocation in Newborns: Risks and Future Considerations - Orthopedics

My newborn baby girl has a dislocated knee?


Hello Dr.
Wang: My recently born daughter dislocated her left knee (according to the doctors, it occurred in utero).
We have been consulting Dr.
Lin at Chengda Hospital, who has helped my daughter with knee rehabilitation and applied a cast.
I would like to ask Dr.
Wang if my daughter will have any long-term effects? Will her mobility be affected? Will she need rehabilitation? Additionally, my daughter had a nuchal cord at birth, which was a natural delivery.
After my wife gave birth, her uterus had poor contraction and there was continuous bleeding (which was later successfully managed).
My question is, if I want to conceive a second child, will this issue occur again? Can you help me understand how to prevent my daughter's condition from happening again in the next pregnancy? Thank you for taking the time to read my questions.

A Zhi, 30~39 year old female. Ask Date: 2005/10/28

Dr. Wang Shouji reply Orthopedics


Hello, A-Zhi: I apologize for the delayed response due to my busy schedule, and I appreciate your understanding.
Congenital knee dislocation can be classified into mild and severe types.
The mild type is often associated with abnormal fetal positioning.
The severe type is related to certain systemic diseases.
It is also important to check for any associated issues with the hip joint or foot.
Based on your daughter's treatment, it appears to be mild.
Rehabilitation is essential after treatment.
The most common issue is the range of motion in the knee joint, which may include difficulty fully extending or bending the knee.
In severe cases, surgical intervention may be required.
As for whether it will occur in the next pregnancy, it is related to its causes.
If it is not due to a systemic disease and is associated with abnormal fetal positioning, there should not be a hereditary tendency.
Wishing you health and happiness.
Wang Shou-ji, Changhua Hospital, cares about your health.

More Info


Knee dislocation in newborns, while rare, can occur during the birthing process, particularly in cases of complicated deliveries. In your situation, it seems that your daughter experienced a knee dislocation at birth, which was subsequently managed with casting by Dr. Lin at Chengda Hospital. Understanding the implications of this condition and the potential for future complications is crucial for both you and your daughter.


Risks and Future Considerations
1. Potential for Long-term Effects: The long-term prognosis for a newborn with a knee dislocation largely depends on the severity of the dislocation and the effectiveness of the treatment. If the dislocation was reduced properly and the knee joint is stabilized with a cast, many children can recover without significant long-term issues. However, there is a possibility of complications such as joint instability, limited range of motion, or even early onset arthritis later in life. Regular follow-ups with an orthopedic specialist will be essential to monitor her knee's development.

2. Need for Rehabilitation: Rehabilitation may be necessary depending on how well the knee heals. Physical therapy can help strengthen the muscles around the knee and improve flexibility, which is crucial for normal function. The need for rehabilitation will be assessed by your healthcare provider as your daughter grows and her knee develops.

3. Mobility Concerns: Initially, your daughter may have some limitations in mobility due to the cast and the healing process. However, most children adapt quickly, and with appropriate treatment, they can often return to normal activities. It's important to encourage gentle movement as she grows, as this will aid in her recovery.


Considerations for Future Pregnancies
Regarding your concerns about future pregnancies, particularly in light of your wife's complications during delivery:
1. Risk of Recurrence: While every pregnancy is unique, certain factors can increase the risk of complications. If your wife experienced uterine atony (poor contraction of the uterus) leading to excessive bleeding, it may be beneficial for her to consult with an obstetrician before attempting to conceive again. They can evaluate her health and provide recommendations to minimize risks in future pregnancies.

2. Preventive Measures: To reduce the likelihood of similar issues in future pregnancies, your wife may be advised to maintain a healthy lifestyle, manage any pre-existing conditions, and receive regular prenatal care. Close monitoring during labor and delivery can also help manage any potential complications more effectively.

3. Genetic Considerations: While knee dislocation itself is not typically hereditary, if there are concerns about joint stability or connective tissue disorders in your family, it may be worth discussing these with a genetic counselor. They can provide insights into any potential risks for future children.


Conclusion
In summary, while your daughter may face some challenges due to her knee dislocation, with proper treatment and monitoring, many children recover well and lead active lives. It's essential to maintain open communication with your healthcare providers to ensure she receives the best care possible. For future pregnancies, consulting with an obstetrician can help address any concerns and develop a plan to minimize risks. Your proactive approach to understanding these issues is commendable and will serve your family well as you navigate these challenges.
