Hamstring injuries in elite Track and Field athletes :
In the current presentation we will present our experience treating ttrack and field athletes with hamstring injuries based on objective clinical measurements (knee range of motion) and ultrasound (US) imaging findings with time to return to athletic activities.A new clinical classification scheme for hamstring injuries” will presented.
Material-Methods: All the athletes with an acute hamstring injury and no history of previous pathology in the posterior thigh or sciatica, were evaluated by measuring the knee active ROM (AROM) deficit compared to the uninjured side, 48 hours after their injury, by two examiners. An age matched group of controls was also examined. An US scan identified the muscle lesion (if present) and measurements (width and length of lesion expressed in cm) in the longitudinal view were performed. All athletes were managed nonoperatively with the same principals and rehabilitation protocol. The “full rehabilitation time” (time interval from the injury to full athletic activities) was recorded.
Results: AROM measurements achieved substantial agreement between theexaminers. US scans showed that biceps femoris was injured in 75% of athletes. Values of width and length of the muscle lesions, measured by US scan, were significantly different comparing mean values between different injury grades. About 45% of the athletes will have returned to full activities within 10 days after their injury and another 35% within 20 days (grades I and II), whereas 16% (grade III) will return after a month and 4% (grade IV) after two months.
Conclusion: Addition to history and clinical examination knee AROM deficit is an objective, reproducible and accurate measurement of the severity of hamstring injuries in athletes. AROM deficit 48 hours after the injury was also predictive of the length of FRT. US imaging we think that is not necessary for I degree injuries following our clinical classification but it is useful for high grade(III-IV) hamstring injuries .

Acute Lateral Ankle Sprains In Track & Field Athletes: A Proposal Of An Expanded Classification
We present a longitudinal observational study on classification of acute lateral ankle ligament injuries in track & field athletes, based on objective criteria. These very common and sometimes troublesome sports injuries are treated functionally but there is a lack in international literature in predicting the time needed for full recovery.
Ten year follow-up study comparing conservative versus operative treatment of anterior cruciate ligament ruptures. A matched-pair analysis of high level athletes
Objective: To compare long term outcome of highly active patients with anterior cruciate ligament ruptures treated operatively versus non-operatively.
Design: We reviewed high level athletes with an anterior cruciate ligament rupture on either MRI or arthroscopic evaluation more than 10 years previously, who were treated conservatively. They were pair-matched with patients who had had an anterior cruciate ligament reconstruction with bone-patella-tendon-bone, with respect to age, gender and Tegner activity score before injury.Participants: In total 50 patients were pair-matched.
Results: We found no statistical difference between the patients treated conservatively or operatively with respect to osteoarthritis or meniscal lesions of the knee, as well as activity level, objective and subjective functional outcome. The patients who were treated operatively had a significantly better stability of the knee at examination.
Conclusion: We conclude that the instability repair using
a bone-patella-tendon-bone anterior cruciate ligament reconstruction is a good knee stabilising operation. Both treatment options however show similar patient outcome at 10 year follow up.
ACL injuries. Diagnosis, treatment and rehabilitation
The ability to recognize the ACL deficient knee is lacking, even among orthopaedic surgeons. The history of an acute ACL tear is remarkably constant, because the injury is often non contact, and patients usually report a twist on the flexed knee, turning to the same side as the injured knee, although hyperextension or direct injury is the cause in some sports. Patients often remember a loud pop, but, because there are no nociceptors in the ACL, pain is not an immediate feature in the isolated lesion. Players may attempt to continue to play, but they usually stop because the knee feels insecure. Pain ensues in association with a hemarthrosis: 70% of acute hemarthroses of the knee are associated with a tear of the ACL. The diagnosis must be confirmed before treatment is offered.
