PURPOSE: After reconstructing a torn ACL with a soft tissue allograft, the long-term healing process of graft maturation following the short-term healing process of graft incorporation into the bone tunnels might lead to recurring instability and concomitant decreases in the activity level, function, and patient satisfaction. Relying on roentgen stereophotogrammetric analysis (RSA), the primary purpose was to determine whether anterior laxity increased and whether patient-reported outcomes declined between 1 and 7 years for a particular graft construct, surgical technique, and rehabilitation programme...

BACKGROUND: Reduced quadriceps strength influences knee function and increases the risk of knee osteoarthritis. Thus, it is of significant clinical relevance to precisely quantify strength deficits in patients with knee injuries. PURPOSE: To evaluate isokinetic concentric quadriceps muscle strength torque values, assessed both from peak torque and at specific knee flexion joint angles, in patients with anterior cruciate ligament (ACL) injury, focal cartilage lesions, and degenerative meniscus tears...

INTRODUCTION: Knee muscles are commonly labelled as flexors or extensors and aptly stabilize the knee against sagittal plane loads. However, how these muscles stabilize the knee against adduction-abduction and rotational loads remains unclear. Our study sought to: (1) classify muscle roles as they relate to joint stability by quantifying the relationship between individual muscle activation patterns and internal net joint moments in all three loading planes, and (2) determine if these roles change with increasing force levels...

This study compared physical fitness components between fatigued and non-fatigued persons with MS and examined those components as correlates of fatigue. Sixty-two ambulatory persons with MS completed the Modified Fatigue Impact Scale (MFIS) and underwent assessments of cardiorespiratory capacity, lower extremity muscle strength (i.e., peak torque and asymmetry), body composition, and static balance over two different sessions 7 days apart. Participants were allocated into fatigue groups based on MFIS scores (non-fatigued group (i...

BACKGROUND: Hip arthroscopy is considered a safe procedure, considering the relatively low rate of complications. Despite several complications have been described following this surgical procedure, the present event has not yet been described. The purpose of the present study is to report an unpublished complication following hip arthroscopy, after reviewing 162 hip arthroscopies and finding iliotibial band syndrome (ITBS) in the knee during followup. MATERIALS AND METHODS: A retrospective review of 162 hip arthroscopies performed between September 2007 and June 2011 was carried out, evaluating patients who presented ITBS during followup...

: High- (HA) and low-arched athletes (LA) experience distinct injury patterns. These injuries are the result of the interaction of structure and biomechanics. A suggested mechanism of patellofemoral pain pertains to frontal plane knee moments which may be exaggerated in LA athletes. We hypothesize that LA athletes will exhibit greater peak knee abduction moments than high-arched athletes. METHODS: Twenty healthy female recreational athletes (10HA and 10LA) performed five over-ground barefoot walking and five barefoot running trials at a self-selected velocity while three-dimensional kinematics and ground reaction forces were recorded...

BACKGROUND: Varus thrust, defined as an abrupt increase of the knee varus angle during weight-bearing in gait, has been shown to be present in patients with moderate to severe knee osteoarthritis and is considered to be one of the risk factors for progression of symptomatic medial knee osteoarthritis. We evaluated the presence and magnitude of varus thrust and its relation with the Knee Adduction Moment in women with early medial knee osteoarthritis, and compared it to that in a group of controls and in a group of subjects with established medial knee osteoarthritis...

Chronic pain in older patients is often treated with pain medications, physical rehabilitation, interventional pain management, and/or psychological interventions. The administration of pain medications is the most common form of chronic pain treatment. Physiologic changes in older adults make them more susceptible to the potential side effects of oral pain medications, especially opioids. Interventional pain management offers an alternative treatment option. This article reviews some of the interventional techniques used to treat the most common sites of pain in older adults: back, knee, and hip...

BACKGROUND: The number of knee arthroplasties performed each year is steadily increasing. Although the outcome is generally favourable, up to 15 % fail to achieve a satisfactory clinical outcome which may indicate that the existing model of rehabilitation after surgery may not be the most efficacious. Given the increasing number of knee arthroplasties, the relative limited physiotherapy resources available and the increasing age and frailty of patients receiving arthroplasty surgery, it is important that we concentrate our rehabilitation resources on those patients who most need help to achieve a good outcome...

BACKGROUND: Knee osteoarthritis (OA) is a leading cause of disability in older adults (≥60) in the UK. If nonsurgical management fails and if OA severity becomes too great, knee arthroplasty is a preferred treatment choice. Preoperative physiotherapy is often offered as part of rehabilitation to improve postoperative patient-based outcomes. OBJECTIVES: Systematically review whether preoperative physiotherapy improves postoperative, patient-based outcomes in older adults who have undergone total knee arthroplasty (TKA) and compare study interventions to best-practice guidelines...

BACKGROUND: Skilled walking, such as obstacle crossing, is an essential component of functional mobility. Sensorimotor integration of visual and proprioceptive inputs is important for successful obstacle crossing. The objective of this study was to understand how proprioceptive deficits affect obstacle-crossing strategies when controlling for variations in motor deficits in ambulatory individuals with spinal cord injury (SCI). METHODS: 15 ambulatory individuals with SCI and 15 able-bodied controls were asked to step over an obstacle scaled to their motor abilities under full and obstructed vision conditions...

BACKGROUND: Following an ACL injury, reconstruction (ACL-R) and rehabilitation, athletes may return to play with a proprioceptive deficit. However, literature is lacking to support this hypothesis in elite athletic groups who have returned to international levels of performance. It is possible the potentially heightened proprioceptive ability evidenced in athletes may negate a deficit following injury. The purpose of this study was to consider the effects of ACL injury, reconstruction and rehabilitation on knee joint position sense (JPS) on a group of elite athletes who had returned to international performance...

Chronic ankle instability is a common pathological consequence of ankle sprains. However, screening tools which assess self-reported dysfunction offer little insight into clinical factors which may be useful to improve deficits. The purpose of this study was to identify factors that contribute most to self-reported dysfunction. 93 individuals completed the Cumberland Ankle Instability Tool (CAIT), active range of motion, dynamic postural stability assessments, and an arthrometer inversion stress test to assess lateral ankle laxity and stiffness...

STUDY DESIGN: Crossover design. CONTEXT: Excessive valgus and varus force which affected the knee joint during dynamic tasks has been often associated to lower extremity injuries. Strategies to increase the resistance against these asymmetries, such as, the use of a physioball between the knees or elastic bands around the knees are often applied in rehabilitation and conditioning programs. OBJECTIVE: The purpose of this study was to investigate the effect of performing leg press (LP) 45° using a physioball and elastic band over multiple sets with submaximal loads on electromyographic (EMG) amplitude and fatigue indices...
