The Anderson Knee and Shoulder Center, located at 2100 Webster Street, Suite 309 in San Francisco, brings together two top San Francisco Orthopedic surgeons - Dr.
Lesley Anderson and Dr. Robert Purchase. Both doctors aim to be among the San Francisco and Marin's best knee and shoulder surgeons, help patients choose the best
nonsurgical or surgical options for knee, shoulder, and other general orthopedic surgery needs. Newest technologies/treatments for arthritis, cartilage and ligament
injuries are passions as well for these two top Bay Area Specialist.
By David Geier, MD
amstring injuries are some of the most
common injuries in football, baseball,
track and field, rugby, and soccer. In fact,
an acute hamstring strain is believed to
be the most common injury in adult male
soccer players, makes up between 12 percent
and 16 percent of all injuries.
Acute hamstring strains usually require a
2- to 6-week absence from sports, and they have
a fairly high recurrence rate, especially in the first
few weeks after return to play. Knowing how
an injury occurs, risk factors and prevention
efforts can help keep athletes healthy.
Acute hamstring strains are generally
noncontact injuries. Sprinting, such as
in passing plays in football and running
from home plate to first base in baseball,
is a common activity leading to injury.
The risk for acute hamstring strain increases
with age and levels of competition. Other
risk factors include imbalances in hamstring
strength, decreased flexibility of the hip
flexors, and higher body weight.
Multiple studies of injuries of American
football show predominance of these injuries
in preseason. Hamstring muscle weakness and
deconditioning of the athletes in the off-season
could be factors in the timing of the injuries.
By far, the biggest risk factor for a hamstring
strain is a history of prior injury. A soccer
player who previously suffered a hamstring
strain is more than twice as likely to suffer
another injury. Inadequate recovery
and rehabilitation from the original
injury and return to play too quickly
could play a role. It is believed
that even with a comprehensive
rehabilitation program, an athlete's
chance of recurrent injury
is still high.
efforts have increased
due to the long
absences from sports
and high recurrence rates.
Identifying athletes with
hamstring strength imbalances
and correcting them and having
athletes perform agility and trunk
stabilization programs may be
beneficial. Given the amount of hamstring
strains occurring in preseason, athletes
should enhance their sport-specific
conditioning prior to the early training
sessions. Focusing on sprinting, interval
running, acceleration drills, and eccentric
hamstring strengthening may prevent
some hamstring injuries.
