Knee Injuries, Surgeries, and Vitamin D Status. The knee joint is one of the largest and complex joints. It connects the thigh bone to the shinbone, which has a very important role in:
Because of the complexity of the knee joint, it is highly susceptible to injuries. The most common injuries include tears in the:

The meniscus is the cartilage between the knee joint that absorbs the impact/shock when running, playing sports, yard work, hiking, bicycling, etc. It cushions the joint and maintains stability.
Meniscus tears are common in sports that have a lot of jumping, starting/stopping quickly, changing direction suddenly, like volleyball, basketball, tennis, soccer, football. This is when the meniscus tears. Surgery can be required, depending on the severity/extent of the injury and tear.
The patellar tendon works with the knee muscles in the front of the thigh to straighten the leg. Tears in the patellar tendon are common among middle-aged individuals and those that participate in running or jumping sports.
Knee dislocations happen when the knee bones shift out of position. This can happen after a fall, car crash, or high-speed impact. It can also be caused by twisting the knee while the foot stays planted. Dislocations require relocation. However, sometimes a dislocated kneecap corrects itself and returns to the proper position. Other cases can require a mild sedative to allow a doctor to relocate the knee. Dislocations generally take around six weeks to fully heal.
The anterior cruciate ligament or ACL is knee tissue that joins the upper and lower leg bones and maintains the knees’ stability. The ACL can be torn if the lower leg over-extends forward or if the leg gets twisted. ACL injuries are common knee injuries and account for around 40% of sports-related injuries. These injuries can range from a small tear in the ligament to a severe injury where the ligament tears completely or gets separated from the bone. Treatment depends on the severity of the injury. Depending on various factors including the severity of the tear, surgery could be required.
For most cases, surgery is done using arthroscopy technology. This procedure uses small incisions to insert a camera and surgical instruments into the joint. Usually, two or three incisions are needed with recovery time being quicker than large incision surgery where the whole knee is opened. Minimally invasive arthroscopic surgery is preferred by sports medicine experts. With this procedure:
However, sometimes a large incision is required for complex surgical techniques. Common knee surgery procedures include:
This method allows the ability to see inside the knee joint. The procedure is often recommended for:
A full knee replacement is known as arthroplasty. When the joint is damaged beyond repair from injury or disease, an implant is placed in the knee joint restoring function. A small amount of cartilage and bone from the shinbone and thigh bone gets removed for perfect placement of the new knee joint.
Most knee replacements last around 15 – 20 years. For individuals that have knee replacement early, then a new operation for new implants could be required. Here, the surgeon removes the original prosthesis and replaces it with a new one.
Some knee injuries do not require complete replacement. Here, only the worn-out portion of the joint is replaced. As an example, the cartilage that has been lost in an area of the knee can be repaired with a partial replacement.
A study on athletes that underwent ACL surgery looked at their vitamin d status and how it affected their recovery.
Each of the patients in this study had their vitamin levels measured before the operation and were grouped based on their vitamin D status:
All were followed for two years with their surgery recovery being measured with two systems.
The Lysholm score, which is a 100 point scoring system that looks at an individual’s knee functions that include:
The WOMAC score is a scoring system that measures:
After 2 years, the Lysholm score and the WOMAC scores were similar.
However, there was a difference in the graft failure rate which was about 6% in group 1 with the lowest vitamin D and around 2% in groups 2 and 3. This shows that the lowest vitamin D status has three times the failure rate compared with those that had increased vitamin D levels. Vitamin D is a known anti-inflammatory with metabolic functions that are documented. Therefore, vitamin D does improve surgical success and recovery in healthy athletes.
