Athletes Injured Young At Higher Risk of Recurring Dislocations Later

About 40 percent of adolescent patients experience a higher risk of recurring patellar dislocation, long-term after their initial surgery.

Patients who suffer patellar dislocations at a very young age are at a greater risk of recurring dislocations, specially long-term after their initial injury, reveals a new study. //

The research was presented at the American Orthopaedic Society for Sports Medicine's Annual Meeting in Toronto, Ontario, Canada.//

Elite Athletes Often Shine Sooner or Later -- but Not Both
A comparison on the performance of elite track and field athletes that were both younger and older than 20 revealed that just a few of the junior athletes see a similar success as their older athletes

‘Educating physicians and parents on the risks young athletes face can help take preventive measures to protect them from these injuries.’

Researchers received the Herodicus Award, presented to the best resident paper featured at the meeting, and determined by the Herodicus Society.

"Our research showed that within the study group, 104 patients had ipsilateral recurrent patellar dislocation, with over 20% of cases occurring in the first two years following the initial injury," noted Thomas L. Sanders, MD, corresponding author from the Mayo Clinic.

"By 15 and 20 years, this number had reached 54% of patients a concerning rate of recurrence."

Obsessive Passion Linked to Athletes Accepting Performance-Enhancing Drugs
Athletes with obsessive passion for their sports are more likely to be lenient towards the use of performance enhancing drugs, or PEDs, revealed a new study.

The study included 232 skeletally immature patients, defined as such if their proximal tibia and distal femoral physes were open at the time of dislocation. Those selected experienced a first-time lateral patellar dislocation between 1990 and 2010.

Subjects were followed for a mean of 12.1 years to determine rates of subsequent dislocations, or clinically significant patellofemoral arthritis.

Arthroscopic Surgery Can be Beneficial for Treating First-Time Shoulder Dislocations - Recent Study
Athletes are more prone to shoulder dislocations, where the upper arm bone gets removed from the cup-shaped socket.

"Despite high numbers of recurrence, our research showed that these young patients did not develop significant patellofemoral arthritis," commented Sanders.

"We hope to use our research to help educate both physicians and parents on the risks young athletes face after these injuries in their early years, and hopefully take steps to prevent them."

The study adds to previous studies, which typically show 40% of adolescent patients go on to experience a recurring patellar dislocation.
