Stretching has been widely used to increase the range of motion. We assessed the effects of a stretching program on muscle-tendon length, flexibility, torque, and activities of daily living of institutionalized older women. Inclusion/exclusion criteria were according to Mini-Mental State Examination (MMSE) (>13), Barthel Index (>13) and Lysholm Scoring Scale (>84). Seventeen 67 ± 9 year-old eld...

BACKGROUND Tunnel enlargement and coalition following double-bundle anterior cruciate ligament (ACL) reconstruction with hamstring tendon autografts has not yet been sufficiently studied. HYPOTHESIS The incidence and the degree of femoral tunnel enlargement will be significantly greater than those for tibial tunnel enlargement after anatomic double-bundle ACL reconstruction using hamstring te...

BACKGROUND Multiligamentous injuries of knee are a complex problem in orthopaedics. Combined ACL-PCL injuries are uncommon, usually associated with knee dislocations. Extremity vascular status is essential because of possible arterio-venous compromise. These complex injuries require a systematic evaluation and treatment. Single setting simultaneous arthroscopic ACL and PCL reconstruction or a s...

Background Quadrupled (4-strand) hamstring tendon autografts are commonly used in anterior cruciate ligament (ACL) reconstruction, but there is significant variability in their diameter. The 5-strand hamstring autograft has been used as a means of increasing the graft diameter in patients with undersized hamstring grafts. Purpose To report the outcomes of primary ACL reconstruction using 5-st...

PURPOSE Hamstring strain reinjury rates can reach 30% within the initial 2 wk after return to sport (RTS). Incomplete recovery of strength may be a contributing factor. However, relative strength of the injured and unaffected limbs at RTS is currently unknown.The purpose was to characterize hamstring strength and morphology at the time of RTS and 6 months later. METHODS Twenty-five athletes w...

BACKGROUND Anterior cruciate ligament (ACL) reconstruction, using hamstring auto-graft is a common surgical procedure, which often leads to persistent hamstring muscle-strength deficiency and reduced function. The purpose of this randomized controlled trial (RCT) is to investigate the effect of a combined, progressive, strength and neuromuscular exercise intervention on knee muscle strength, fu...

PURPOSE The goal of this study was to evaluate the clinical outcome of single-bundle posterior cruciate ligament (PCL) reconstruction with retention of the PCL remnant and hamstring tendon autograft with interference screw fixation in patients with isolated PCL laxity. TYPE OF STUDY Prospective case series with minimum 2-year follow-up evaluation. METHODS Thirty-one patients for whom conser...

Purpose  The purpose of this study was to retrospectively evaluate the clinical outcome of revision anterior cruciate ligament (ACL) reconstruction with contralateral hamstring tendon autografts, specifically with regard to patient satisfaction, return to preinjury activity level, and postoperative functional outcomes. Methods  Between 2004 and 2011, 23 patients underwent revision ACL reconstru...

The purpose of this study was to evaluate the existence of differences in the rehabilitation of patients after ACL reconstruction using bone-patellar tendon-bone graft and the four-strand semitendinosus and gracilis tendon grafts, through a literature revision. The researched databases were MEDLINE, EMBASE, LILACS, COCHRANE and PEDro. The inclusion criteria were published studies with methodolo...

Why do some hamstring and quadriceps strains take much longer to repair than others? Which injuries are more prone to recurrence? Intramuscular tendon injuries have received little attention as an element in 'muscle strain'. In thigh muscles, such as rectus femoris and biceps femoris, the attached tendon extends for a significant distance within the muscle belly. While the pathology of most mus...
