    Is there any way to repair or rebuild torn cartilage?

    Whether any biological tissue will repair or not depends on many factors including: the nature of the tissue; where the tissue is located; what forces act on the tissue; and what nutrients are available to assist with the repair. If the athlete is young (has many stem cells available) and the tissue is subjected to rest, then the tissue will generally heal quickly. Cartilage is interesting, particularly in the knee. There is an area within the knee cartilage (meniscus) that has a poor blood supply and if the tear is in that particular area, the chances are that it will require surgery to repair it. Nutritional supplements including glucosamine and chondroitin have shown in some studies to assist in the healing of cartilage and degenerative joints.

    I have a small, bony growth on my big toe. What is it and should I have it removed?

    This doesn’t sound very ominous, but a growth anywhere on the body needs to be inspected and evaluated by a doctor, particularly if it is getting larger over time. The doc should be able to determine if the growth has a more malignant (harmful) or benign (harmless) appearance. The doc should also try to determine if the growth is bony or consists of soft tissue; solid or cystic; painful or painless; and, very importantly, is it attached to or separate from the underlying tissues. All of these features will assist the doc to decide if a biopsy is necessary and if the growth needs to be removed.

    Will a sauna help my muscles recover faster after an intense weight workout?

    The role of (extreme) temperature manipulation – heating and cooling – in the recovery of heavily exercised skeletal muscles has been debated for years and remains controversial. Many athletes swear blindly that their personal strategy works, though no scientific studies have shown quicker or slower recovery rates with a sauna. There is also an equal number of studies that do and do not show that cooling the muscle assists in recovery. Many Super 14 and other elite teams use cooling in their recovery plans (either refrigeration rooms or ice baths), but none (to the best of my knowledge) use heat.
