My daughter (19 years old) fell from the stairs a month ago. Initially, she suffered from bruises on her knees, but we didn’t go to a doctor. This one week, she has been experiencing so much pain on her knees, especially when she moves. The doctor suggested she undergo an MRI. According to the doctor, her meniscus is a bit torn and he has advised she undergo arthroscopy. Is it necessary, Doctor, or is there any other way?
dr. Ang Chia Liang replied 2 years ago

Likely the meniscus tear is not going to heal properly on its own. It has been causing her pain for one month and now the pain is worse. At 19 years old, it is better to undergo Arthroscopy to repair the meniscus. The important thing is to repair the meniscus, so that she can have a good knee for many more years to come. Without repair, it is likely that she will have on-going pain in the knee.

Doctor, I am 22 years old with 30 degrees of scoliosis. My orthopaedic doctor suggested only to wear traction. But I am not confident with my appearance now. Can I ask for a surgery to fix my back bone?
dr. Ang Chia Liang replied 2 years ago

The types of surgery to fix scoliosis involves putting in metal implants and the back will become more stiff and less flexible. Fixing the back bone at 22 years old can improve your appearance but will decrease your function. Also, there is a risk of requiring further surgeries in future when other parts of the back bone gives problems. On the whole, it may be better not to operate at 22 years old with 30 degrees of scoliosis, unless yearly monitoring shows progression of scoliosis.

Doctor, I am 50 years old. I had herniated nucleus pulposus (HNP) in L4 and L5. I went for a surgery to implant two pieces of silicones 4 years ago. But I have been feeling pain in my back lately, whenever I sit or when I stand up after sitting. Is this a sign of recurrence of my problem? What should I do?
dr. Ang Chia Liang replied 2 years ago

When pain comes back after some time, it could be a sign of further degeneration of the spine, or issues related to the silicone implant. You should undergo an "MRI scan of the lumbar spine with contrast" to check the current condition first.

I have been feeling pain on my tailbone if I sit for too long. But my work keeps me sitting all day. Are there any suggestions for me to fix this problem?
dr. Ang Chia Liang replied 2 years ago

Tailbone pain is something that may take a long time to recover from. A few suggestions to help you are:

1) Take regular breaks from sitting. Stand up and stretch every 1 – 2 hours
2) Daily exercises to stretch the muscles around the tailbone. You can refer to
3) Make sure your seat has a lumbar support and push your back against the support
4) Use a ring cushion to avoid pressure on the tailbone

Every time I rotate my thumb, I hear a “cracking” sound. It hurts as well. What condition is this, Doctor?
dr. Ang Chia Liang replied 2 years ago

A cracking sound and pain indicates one of two things usually: it could be an injury of the ligament around the thumb, or it could be degeneration of the cartilage in the thumb.

There are treatments for these conditions but you will need a physical examination and maybe MRI too.

I have a crooked spine. Is it treatable? What should I do to fix this problem?
dr. Ang Chia Liang replied 2 years ago

A hunched spine/posture is not uncommon. A lot of the times, it is to do with each person's bone and muscle structure that he becomes hunched.

If there is no pain, you can do regular back and neck core exercises to strengthen the core muscles and get a better posture. You can learn from a professional such as a Physiotherapist. Other things to do to help you maintain good posture is using a chair with a lumbar support and sitting all the way back in the chair to ensure your spine is straight. Doing these can help you correct the posture to some extent.
