Three young men running and playing footballSuper Bowl excitement is taking a hold of the San Francisco Bay Area as we prepare for hundreds of thousands of visitors to come and enjoy the game and our beautiful City by the Bay. Some of you may be inspired to go out for a pick-up game in the local park. Before you go, be aware of the risks of injury.

There are four main categories of injuries that are common among football players: traumatic injuries, concussions, overuse injuries and heat sickness. Today we will focus on traumatic injuries.

Perhaps the most common traumatic injury among football players occurs in the knee. Specifically, players are prone to tearing their anterior cruciate ligament (ACL) and less commonly, their posterior cruciate ligament (PCL). Changing direction rapidly or landing from a jump incorrectly can tear the ACL. The posterior cruciate ligament is often injured from a blow to the front of the knee while the knee is bent. Meniscus tears are also common, and can can occur when twisting, cutting, pivoting, or being tackled.

New Study Suggests Exercise as Best Treatment for Lower Back Pain

Lower Back PainIf you are like most Americans, you have likely experienced an episode of lower back pain at some point in your life. You may have tried a variety of self-help preventive treatments such as special insoles or back braces. However, a new study this week, published in the Journal of the American Medical Association Internal Medicine (JAMA) suggests that exercise may be the best treatment, and those other treatments may be a waste of money.

Researchers reviewed 21 clinical studies, which included over 30,000 people who had suffered an acute episode of lower back pain, and how they were treated. They determined that exercise — almost any exercise — reduced the risk of a repeat episode within a year by 25 to 40 percent. The exercise must be sustained, however. The study did show that the prevention benefit of exercise decreases after a year.

How to Get Fit and Avoid Injury

Woman Running by the BayLike clockwork, the gym fills up in the days immediately following the indulgences of the holiday season. The regulars, the ones who have been coming (somewhat) faithfully over the previous year roll their eyes and wish for the quieter days of February, when many of the “newbies” will have lost their resolve to get fit.

Most concerning during January, either at the gym, the court, on the track, or the on-the-street urban boot camp is the risk of injury among novices as well as rejuvenated former athletes. Many exercise-related injuries are due to overuse of a muscle or a joint. These overuse injuries often are a result of taking on too much too soon, or from improper technique.

Before you launch your next couch-to-marathon mobile app, we strongly recommend these simple steps to avoid injury:

Joint Conversations With Doctor Peter Callander – Knee Arthritis and Knee Replacement Surgery

In the following Joint Conversations interview put on as part of the Sutter Health Novato Community Hospital Bone & Joint program, we learn about orthopedic surgeon, Doctor Peter Callander who specializes in hip & knee replacement surgery. Doctor Callander currently serves as the director of the Bone & Joint Program at the Novato Community Hospital and is also the company physician for the San Francisco Ballet.

One of the more common reasons for a joint replacement is arthritis. This type of arthritis occurs when cartilage in a joint has worn away leaving bones to come in contact with each other resulting in inflammation of the joint, pain, and stiffness. This specific type of joint inflammation or arthritis is called osteoarthritis and generally happens later on in life after a person has worn down the cartilage in their joint. However, osteoarthritis doesn’t always effect people in their later years, genetic factors and joint trauma can cause osteoarthritis to affect people in their younger years.

Knee Replacement Surgery More Precise With New Technology

In In The News, Robert E. Mayle MD

Millions of Americans undergo Knee Replacement Surgery every year but the success of the surgery depends on whether or not the replacement fits. A new device being used in the Bay Area is making knee replacement surgeries more precise. The device, known as Verasense, is part of a system that helps ensure a better fit for knee replacement. To get the best fit the Verasense device is first inserted into the knee. The device is almost the same size as the knee replacement but is embedded with a microchip sensor that beams data to a monitor next to the operating table. As the knee is moved during surgery the sensor measures the pressure at different points on the surface of the joint. If the Verasense is off balance the surgeon can remove bone or tissue to smooth out the movement. If it is too loose or too tight the surgeon can use thicker or thinner replacement caps. After the knee is in balance the surgeon can fit the patient with permanent replacement caps that will be the contact point of the new knee.

Doctor Robert Mayle Donates An Orthopedic Surgery

Salomon Zapeda had been in constant pain for over a year after he injured his knee at work. An MRI showed a torn meniscus in his knee that is a common injury routinely repaired, but Salomon didn’t have access to health insurance or Medi-Cal.  Operation Access, a Bay Area nonprofit that helps pair low-income and undocumented families with health care resources, was able to pair Salomon with CPOSM orthopedic surgeon Doctor Mayle who performed the orthopedic surgery free of charge. The goal of the donated surgery was to clean up Salomon’s torn meniscus and then allow him to regain his strength and range of motion over the next couple of weeks.

Hip ReplacementIn the following interview with Doctor Mayle on KSRO’s Joint Conversations, we learn about Doctor Mayle of California Pacific Orthopedics and Sports Medicine, and his field of expertise – hip & knee replacement.  Surprisingly enough, Dr. Mayle’s patients run from the age of 25 to the age of 100. Factors such as genetics, injury and general wear and tear of the joint can all cause the need for a replacement. Doctor Mayle also talks about hip arthritis and the symptoms that may arise from loss of cartilage.

Scuba Diving Only Six Weeks After Hip Replacement

In the video above, Judith floats slowly towards her underwater GoPro video camera and bit by bit shows a message for Dr. Callander, “New Hip, Scoped Knee, THANK YOU Doctor Callander!”

Scuba diving and underwater video have been Judith’s hobby since 1996 and she has completed 500 dives. Prior to surgery, Judith experienced difficulty with getting her scuba gear on and off and at times lacked confidence on difficult dives due to increasing problems with her hip and knee. Following surgery, with Doctor Callander, Judith returned to scuba diving within six weeks. Although Judith is retired, she continues to travel the world and scuba dive in both calm waters and at times the more difficult dives of rougher conditions in remote locations like the Fiji islands.

Hip Arthroscopy Procedure Not Exclusive to Professional Athletes

Reports on SF Giants’ pitcher Tim Lincecum are showing an excellent prognosis after his recent surgery on his left hip. While he has a significant recovery time to return to his major league pitching, surgeons are suggesting he may be able to participate in spring training next year.

“The procedure, called hip arthroscopy, is an innovative procedure that provides certain patients who may be at risk for early hip arthritis with an option to potentially prevent hip replacement surgery,” says CPOSM’s orthopedic surgeon Keith Chan, MD, who specializes in this minimally invasive procedure. “For certain patients, particularly those who are very active, this can be an excellent option.”

Competitive Kickboxing After Hip Resurfacing

Two years after his hip resurfacing operation with CPOSM’s Dr. Peter Callander, Ryan Roy can sit in a full lotus position for the first time in his life. He says he has more strength and flexibility in his hips than ever before because of his extensive rehabilitation program. In April 2015, he returned to the ring as the first professional Muay Thai kickboxer with a metal hip joint.

Ryan Roy has been training as a Muay Thai kickboxer since the age of 17 and is dedicated to his sport. In 2011 he started to experience increasingly severe hip pain – it got so bad that he couldn’t sleep and found it difficult to continue teaching kickboxing at his gym in Mountain View, T2 Muay Thai. X-rays confirmed that the cartilage in one hip joint was gone. He went to a series of hip specialists who all said that he needed a Total Hip Replacement (THR). Because traditional hip replacements increase the risk of joint dislocation, a THR operation would probably have ended Ryan’s career as professional kickboxer. In his words, this was “just not an option.”
