Glossary of Knee Terms Introduction Although we are keen and experienced skiers this page is not intended to be a didactic and authoritative reference on skiing knee injuries. We will leave aside obvious general factors like skill levels, terrain, snow and weather conditions, fitness and tiredness and concentrate on numerous physical and clinical issues which we are interested in.

Therefore, the content of this page is specific to our clinical practice and reflects our orthopedic interests, in particular skiing-injury related knee problems ligament, chondral and subchondral injuries.

The number of people in the UK who ski or snowboard is rising - over 1. Unfortunately, as with every other outdoor sport, snow sports are associated with a risk of injury. But that risk is much lower than most people believe - less than 0.

Generally, it is safe to say that skiing and snowboarding are indeed safe sports. Also, other studies revealed a lower risk for sustaining knee injuries when using carving skis compared with traditional skis.

Bicycle Helmets for the Season Many competitions also require the rider to do a complex trick. But not all competitions call for a trick to win the gold; some intermittent competitions are based solely on height and distance of the launch of the snowboarder.

Due to the introduction of the short and shaped carving skis, the distribution of ACL injury mechanisms seems to have changed in recreational skiing.

Recent studies on carving skiers indicate that the main ACL injury mechanism in recreational skiing is a forward twisting fall creating a valgus external rotation of the knee joint. It seems likely that the shorter length of carving skis compared with traditional skis causes a change in the distribution of ACL injury mechanisms in recreational skiing from the backward twisting fall which seems to be a typical mechanism of ACL injury among elite competitive skier to the forward twisting fall.

For recreational skiing, it seems likely that the use of carving skis altered the distribution of the most common ACL injury mechanisms contributing to a decrease in the ACL injury risk.

Gerhard Ruedl et al. Letter to the Editor. AJSM October re: Bere T et al.: More than 9 out of 10 of the injured skiers were women, with an average age of Women aged over 25 are 2.

Fitness, or the lack of it, plays an important role in general. Women are also more likely than men to suffer a serious knee injury due to ill-fitting ski boots - up to half of all knee injuries are caused by loose-fitting or over-tightened ski boots. Although female knees seem to be anatomically more susceptible to such injury, anatomic differences in the distal femur the width of the intercondylar notch do not appear to contribute to the sex difference in ACL injury rates.

The results of the study performed by Anderson and collaborators 1 give credence to the hypothesis that the sex difference in ACL tear rates is caused primarily by a difference in several interrelated intrinsic factors, including body fat, strength of the hamstring and quadriceps muscles, and the size of the ACL.

The phase of menstrual cycle may be one of the risk factors that influence knee ligament injury among female alpine skiers. The likelihood of sustaining an anterior cruciate ligament injury does not remain constant during the menstrual cycle: Female athletes are between two and eight times more likely to injure their anterior cruciate ligaments than men 3.

In our clinical practice we have also seen increased numbers of female skiing knee injuries in skiers at all skill levels resulting in partial MCL and full ACL tears.

These injuries are almost always associated with extensive subchondral injuries bone bruising and bone marrow oedema. Typically, most injuries in this group involve slow speed, slow deceleration and twisting in relatively deep snow.

Most of the time the bindings do not release or release too late, which is not surprising as many other ski knee injuries occur because bindings fail to release. Beynnon, PhD, et al.: The American Journal of Sports Medicine Hormones affect knee laxity, but effects vary among patients: Not all women, however, experience the KJL changes at the same time during their cycles.

The authors assessed serum samples, KJL, and knee joint mechanics angle, moment, and impulse at the follicular, ovulation, and luteal phases in 26 women.

They found no significant differences in knee joint mechanics across the menstrual cycle no phase effect.Blowout on the Bayou.
