BACKGROUND Hamstring muscle strains often recur. The authors studied the effect of the grade of initial injury on the subsequent risk of reinjury. HYPOTHESIS No difference in reinjury rate between acute low-grade (grades I and II) and high-grade (III and IV) hamstring muscle strains would be seen. STUDY DESIGN Cohort study (prognosis); Level of evidence, 1. METHODS Between 1999 and 2007, ...

The purpose of this study was to examine intratester reliability of a test designed to measure tightness in the hamstring muscles. The test measures the angle of knee flexion with a pendulum goniometer after active knee extension with the hip stabilized at 90 degrees flexion. The angle of knee flexion represents hamstring tightness. After an instruction session for the subjects, the hamstring m...

High hamstring tendinopathy is an uncommon overuse injury seen in running athletes. Patients typically report deep buttock or thigh pain. A detailed physical examination and, occasionally, imaging studies are necessary to confirm the diagnosis. Rehabilitation involves soft-tissue mobilization, frequent stretching, and progressive eccentric hamstring strengthening and core stabilization exercise...

[Purpose] The aim of this study was to investigate the effect of kinesio taping (KT) on the kinematics of the lumbo-pelvic-hip complex during forward bending by individuals with reduced hamstring extensibility. [Subjects] Eighteen males with reduced hamstring extensibility were randomly assigned to one of two groups:, the hamstring KT group (n=9), or the sham KT group (n=9). [Methods] The kinem...

Background: Hamstring muscle injuries are among the most common lower extremity injuries in athletes. Pain in the posterior thigh and leg weakness are usual presenting symptoms. Less dramatic onset in nonathletes, without pain in the posterior thigh, is more often thought of as an ischial bursitis or as pain from the sacroiliac joint or the gluteal or piriformis muscles. Pain localized over the...

The use of autogenous hamstring tendon as a graft source for anterior cruciate ligament (ACL) reconstruction continues to gain in popularity. The low harvest morbidity and excellent biomechanical graft properties coupled with improved fixation of soft tissue grafts are all reasons for excellent clinical outcomes of ACL reconstruction using hamstring tendons. In addition, surgeon awareness of th...

Proximal hamstring avulsions from the ischium are becoming more frequently recognized, secondary to their disability when treated nonoperatively. The acute repair of these injuries is becoming prevalent given the improved outcomes reported in the literature. Anatomic studies have recently been conducted on the proximal hamstring origin; however, there are few reports on surgical techniques for ...

Treatment of proximal hamstring avulsions is challenging regarding both timing and choice of repair. In chronic situations, the tissue can become attenuated, bringing into question the need for adjunctive allograft. In general, proximal hamstring avulsions are affixed back to the ischial tuberosity with suture anchors, with allograft used as needed for chronic situations. This article reports o...

Anterior cruciate ligament reconstruction is one of the most commonly performed procedures in orthopaedics, with more than 125,000 performed in the United States per year. There are several reconstruction graft choices that can be used to reconstruct the native anterior cruciate ligament, with autograft hamstring tendons being one of the most commonly used. Preparation of a hamstring autograft ...
