BACKGROUND: Results of anterior cruciate ligament (ACL) reconstruction are traditionally excellent in younger and nonarthritic patients. During the past few decades, people older than 60 years have become more active than ever, with more demanding physical lifestyles. An increase also has been noted in active patients with diagnosed ACL injuries. More patients are requesting treatment for ACL deficiency in hopes of returning to preinjury levels of activity. PURPOSE: The aims of this study were to evaluate the results of ACL reconstruction in patients older than 60 years in terms of functional recovery, return to sports, and postoperative incidence of osteoarthritis and to compare their results with published results of different age groups...

OBJECTIVES: With the increasing number of primary anterior cruciate ligament (ACL) reconstructions, the need for revision ACL surgery has risen over the past few years. The purpose of the present study is to retrospectively compare the clinical outcome of ipsilateral versus contralateral hamstring tendon autografts for ACL revision surgery, specifically with regard to patient satisfaction, post-operative functional outcomes, and return to sports. METHODS: Between 2004 and 2011, 64 patients underwent ACL revision surgery...

Tears of the patellar and quadriceps tendon are common in the active population, especially in athletes. At present, several techniques for surgical repair and reconstruction are available. When reruptures occur, a reconstruction is mandatory. In the present paper, we describe a surgical technique for patellar and quadriceps tendon reconstruction using ipsilateral hamstring autograft. After routine hamstring tendon harvesting, the tendon ends are prepared using a whip stitch. A transverse tunnel is drilled in the midportion of the patella, the hamstring graft is passed through the patella, and firmly secured to the patellar tunnel openings with sutures...

BACKGROUND: Rehabilitation progression and return-to-play (RTP) decision making following hamstring strain injury (HSI) can be challenging for clinicians, owing to the competing demands of reducing both convalescence and the risk of re-injury. Despite an increased focus on the RTP process following HSI, little attention has been paid to rehabilitation progression and RTP criteria, and subsequent time taken to RTP and re-injury rates. OBJECTIVE: The aim of this systematic review is to identify rehabilitation progression and RTP criteria implemented following HSI and examine the subsequent time taken to RTP and rates of re-injury...

Proximal hamstring avulsion is an uncommon muscle injury with a lack of consensus on indications and the timing and technique of surgery. Poor clinical symptoms and difficulties in the diagnostic process can lead to a false diagnosis. The authors present three cases of proximal hamstring avulsion, two complete and one partial ruptures of the biceps femoris muscle. MRI and ultrasound scans were used for optimal treatment alignment. Acute surgery reconstruction (< 4 weeks) was done in two patients. Re-attachment of the full thickness ruptures was performed to the original place and secured by suture anchors, the partial rupture was fixed by a simple suture...

Tibiofemoral knee dislocation is a rare but serious limb-threatening injury. Without prompt recognition and management, amputation or long-term functional impairment may result. The authors present a case of bilateral sequential knee dislocation, secondary to low-energy trauma, in a patient with Systemic Lupus Erythematosus and antiphospholipid syndrome. Adequate stability was achieved on both occasions by reconstruction of the postero-lateral corner and MCL. During the first reconstruction, ipsi-lateral autograft, as well as hamstring tendons from the contra-lateral side, were used to strengthen the graft...

: Reduced physical activity is a primary risk factor for increased morbidity and mortality, People with spinal cord injury (SCI) have reduced activity for a lifetime, as they cannot volitionally activate affected skeletal muscles. We explored whether low force and low frequency stimulation is a viable strategy to enhance systemic energy expenditure in people with SCI. PURPOSE: To determine the effects of low stimulation frequency (1 Hz, 3 Hz) and stimulation intensity (50 mA and 100 mA) on energy expenditure in people with SCI...

BACKGROUND: T20 (Twenty20 or 20 over) cricket has emerged in the last decade as the most popular form of cricket (in terms of spectator attendances). International consensus cricket definitions, first published in 2005, were updated in 2016 to better reflect the rise to prominence of T20 cricket. METHODS: Injury incidence and prevalence rates were calculated using the new international methods and units for elite senior male Australian cricketers over the past decade (season 2006-2007 to season 2015-2016 inclusive)...

Although most ACL injury prevention programmes encourage greater hip and knee flexion during landing, it remains unknown how this technique influences tibiofemoral joint forces. We examined whether a landing strategy utilising greater hip and knee flexion decreases tibiofemoral anterior shear and compression. Twelve healthy women (25.9 ± 3.5 years) performed a drop-jump task before and after a training session (10-15 min) that emphasised greater hip and knee flexion. Peak tibiofemoral anterior shear and compressive forces were calculated using an electromyography (EMG)-driven knee model that incorporated joint kinematics, EMG and participant-specific muscle volumes and patella tendon orientation measured using magnetic resonance imaging (MRI)...

BACKGROUND: Small-diameter hamstring tendons are frequently encountered during anterior cruciate ligament (ACL) reconstructions in patients with short stature or those who are skeletally immature. The role of augmenting these small-diameter autografts with allograft is unclear. PURPOSE: To assess clinical outcomes and failure rates in adolescent patients with small hamstring tendon autografts (<7 mm) that were either augmented with soft tissue allograft or accepted "as is" and not augmented...

CONTEXT: Neurodynamic tension affects hamstring extensibility and stretch tolerance, and is considered important in hamstring injury management. Neurodynamic tension was postulated to affect segmental muscle extensibility and stretch tolerance, and potentially also demonstrate extra-segmental and contralateral effects. OBJECTIVES: Assess the effects of a novel sciatic-tibial neurodynamic tension technique, the modified long sit slump (MLSS), on segmental, extra-segmental and contralateral muscle extensibility and stretch tolerance...

Rupture of the proximal tendon enthesis of the hamstring muscle (ICM) accounts for approximately 10% of all injuries of the ICM. It occurs most commonly in athletes and active middle-aged individuals. The complete rupture of all three tendons in active patients is generally seen as an indication for surgical repair of the tendon enthesis; however, the correct diagnosis is often not reached in a timely manner. This can lead to prolonged symptoms with pain, weakness and neuralgia. Operative treatment consists of anchor repair of the tendons resulting in good clinical outcome in several case series...

BACKGROUND: To investigate the association between running exposure and the risk of hamstring strain injury (HSI) in elite Australian footballers. METHODS: Elite Australian footballers (n=220) from 5 different teams participated. Global positioning system (GPS) data were provided for every athlete for each training session and match for the entire 2015 season. The occurrences of HSIs throughout the study period were reported. Receiver operator characteristic curve analyses were performed and the relative risk (RR) of subsequent HSI was calculated for absolute and relative running exposure variables related to distance covered above 10 and 24 km/hour in the preceding week/s...

The rehabilitation process begins immediately after injury to the anterior cruciate ligament (ACL). The goal of preoperative rehabilitation is to prepare the patient for surgery. Current rehabilitation programs focus on strengthening exercises and proprioceptive and neuromuscular control drills to provide a neurologic stimulus. It is also important to address preexisting factors, especially for the female athlete, that may predispose to future injury, such as hip and hamstring weakness. Our goal in the rehabilitation program is to restore full, unrestricted function and to assist the patient to return to 100% of the preinjury level while achieving excellent long-term outcomes...
