Soo-Hyun Kim, Sang-Ho Ahn, Gil-Su Jung, Jin-Hyun Kim, Yun-Woo Cho
[Purpose] The biomechanical effects of foot orthoses on malalignment syndrome have not been fully clarified. This experimental investigation was conducted to evaluate the effects of orthoses on the gait patterns of patients with malalignment syndrome. [Subjects and Methods] Ten patients with malalignment syndrome were recruited. For each participant, kinematic and kinetic data were collected under three test conditions: walking barefoot, walking with flat insoles in shoes, and walking with a biomechanical foot orthosis (BFO) in shoes...

More than 80% of runners are out of alignment. The standard back examination should include assessment of pelvic alignment. An awareness of pelvic malalignment and the the malalignment syndrome is essential to allow one to provide proper care of a runner. The 3 most common presentations usually respond to a supervised, progressive treatment program. The validity of any research into the biomechanics of running should be questioned if the study has failed to look at whether pelvic malalignment was present and whether the altered, asymmetrical biomechanical changes attributable to the malalignment itself could have affected the results of the study...

BACKGROUND: Knee pain in cerebral palsy (CP) is associated with increased patellofemoral forces present when walking with flexed knees. In typically developing children, knee pain and patellofemoral dysfunction are associated with obesity, genu valgum, femoral anteversion, and external tibial torsion. These problems are also common in CP, and may contribute to knee problems in this population. The purposes of this study were to define the prevalence of knee pain and patellofemoral dysfunction in children with CP, and to identify physical and gait characteristics (using 3-dimensional gait analysis data) that predispose them to such problems...

49 patients underwent subcutaneous lateral retinacular release for pa tell of emo ral malalignment syndromes by a new technique utilizing the arthroscope and electrocautery. In this technique, the tight lateral patellofemoral ligament and lateral retinaculum are transected with the electrocautery under direct arthroscopic visualization. It is possible to directly observe the progress and completeness of the release, and to cauterize any bleeding vessels sequentially as they are transected. The procedure is simple, quick, and has a low 3...

BACKGROUND: Torsional malalignment syndrome (TMS) is a well defined condition consisting of a combination of femoral antetorsion and tibial lateral torsion. The axis of knee motion is medially rotated. This may lead to patellofemoral malalignment with an increased Q angle and chondromalacia, patellar subluxation and dislocation. Conservative management is recommended in all but the most rare and severest cases. In these cases deformity correction requires osteotomies at two levels per limb...

INTRODUCTION: Pelvic tilt is an established measure of position which has been tied to sagittal plane spinal deformity. Increased tilt is noted in the setting of the aging spine and sagittal malalignment syndromes such as flatback (compensatory mechanism). However, the femoral heads are often poorly visualized on sagittal films of scoliosis series in adults, limiting the ability to determine pelvic incidence and tilt. There is a need to establish a coronal plane (better visualization) pelvic parameter which correlates closely with pelvic tilt...

Patella malalignment syndrome is characterized by pain in the anterior portion of the knee. There can be numerous causes; however, the end result appears to be excessive lateral pressure on the patellofemoral articulation. This problem commonly affects athletes as an overuse injury. Standard conservative treatment attempts to decrease inflammation and increase strength whereas surgical techniques seek to correct the actual cause of the malalignment. The biomechanical approach advocated in this article employs the standard conservative treatments in addition to a passive forced technique designed to reduce lateral pressure by stretching the lateral retinaculum and patella compression to facilitate cartilage metabolism...

Patellar malalignment syndrome is a condition that presents with clinical symptoms such as popping, giving-way, effusion, buckling, weakness, patellar subluxation, and pain with certain activities. Realignment of the patella through conservative techniques has become the main emphasis of treatment. Due to this emphasis on patellar realignment, a need for a quantitative measurement of patellar orientation has developed. The A-angle is a goniometric measurement that assesses the relationship of the patella to the tibial tubercle...

INTRODUCTION: Imbalanced soft tissue tension between medial and lateral para-patellar structures is the most common pathogenic cause of patellar malalignment syndrome. Despite the fact that an effective technique has not been developed, this disorder is usually treated conservatively. This prospective study tried to identify an effective alternative treatment for patellar malalignment syndrome. MATERIALS AND METHODS: Forty female patients (age, 20-40 years) with bilateral patellar malalignment syndrome were randomly divided into two groups...

We present a long-term review of a girl aged 11 years and 4 months with medial primary recurrent subluxation of both patellae of several months evolution associated with miserably malalignment syndrome. Not one case of medial recurrent dislocation of the patellae has been described previously. Three years previously following a jump she had suffered a right patellar luxation - self-reduced and not immobilised - followed by 10 subsequent episodes of subluxation and three more medial luxations. She could hardly walk autonomously due to persistent or habitual subluxation and patellofemoral pain, mainly in the right knee...

BACKGROUND: Pelvic floor muscles have potential to influence relative pelvic alignment. Side asymmetry in pelvic floor muscle tension is claimed to induce pelvic malalignment. However, its nature and amplitude are not clear. There is a need for non-invasive and reliable assessment method. An intervention experiment of unilateral pelvic floor muscle activation on healthy females was performed using image data for intra-subject comparison of normal and altered configuration of bony pelvis...

Anterior knee pain is one of the more frustrating problems that orthopaedic surgeons treat. This study investigates the results of surgical correction of miserable malalignment syndrome associated with significant patellofemoral pain. The authors identified and retrospectively reviewed 14 consecutive patients with 27 limbs associated with excessive femoral anteversion, excessive tibial outward rotation, and patellofemoral pain. All of the patients were initially reviewed by the senior author and subsequently treated by ipsilateral outward femoral osteotomy and inward tibial osteotomy...

PURPOSE: Bracing is commonly used to correct patellar malalignment syndromes. However, there are little objective data documenting the effect of such supports on patellofemoral joint relationships. The purpose of this study was to assess the effectiveness of an elastic patellofemoral sleeve brace in altering patellar tracking in subjects with patellofemoral pain. METHODS: Ten female subjects (12 patellofemoral joints) between the ages of 17 and 46 participated in this study...

Over a 7-year period (1984-1991), nine patients (aged 10-18 years) with 13 involved extremities were operatively treated for symptomatic severe torsional malalignment of the lower extremity and associated patellofemoral pathology. Physical examination and analysis of gait revealed severe rotational deformity characterized by excessive femoral anteversion and external tibial torsion. The cosmetic and functional pathologic effect of this torsional malalignment was centered about the knee joint. In all patients, conservative treatment, including therapy for muscle strengthening and nonsteroidal medication, was unsuccessful in alleviating suspected patellofemoral pain...

Fourteen children (19 feet) ranging in age from 2.1 to 17.0 years (mean, 7.6 years) underwent tibial osteotomy for treatment of congenital talipes equinovarus (CTEV). The indications for tibial osteotomy were persistent or recurrent equinovarus deformity and internal rotation of the foot (medial malalignment syndrome), in most cases with severe distortion of the hindfoot joints resulting from previous operations. In 12 feet (9 children), bi- or triplanar supramalleolar osteotomy for the correction of all the elements of the deformity was performed...

Retropatellar pain often accompanies malalignment syndromes and frequently is attributed to excessive patellofemoral contact stresses. Elevation (anterior displacement) of the tibial tubercle has been recommended to relieve these conditions. The degree to which patellar contact forces are decreased and the extent to which elevation alters medial-lateral forces have not been studied directly. We performed anterior translation of the tibial tubercle in knees from cadavers and measured the effect on the magnitude of the three-dimensional patellofemoral contact force with use of a specially designed 6-degrees-of-freedom force transducer, with the natural patellar articular surface in place...

In 29 patients with patellofemoral complaints paired values of Q-angle and internal hip rotation were determined. In addition the patellar height index of Insall & Salvati (1971) was calculated from measurements on lateral radiographs of the knees. Both Q-angle and internal hip rotation were significantly higher in women than in men and there was a statistically significant correlation between these two measurements. There was no significant correlation between Q-angles and patellar height indexes. As external hip rotation can generally be taken as a measure of internal femoral torsion, these findings favour the hypothesis of a torsional malalignment syndrome of the patellofemoral joint...

Eighteen patients (26 knees) giving a history of patellar dislocation and/or subluxation and continued patellar symptoms underwent evaluation to determine the efficacy of their rehabilitation programs. Four-channel cine-electromyography was utilized to assess the relative muscular effort of the vastus medialis, vastus lateralis, vastus medialis obliquus, and rectus femoris in a series of exercises. Ten degrees of flexion of the knee reduced effective muscle effort in the vasti group to an average of 1/4 of the muscle effort demonstrated in full extension of the knee...

Patellar pain must be separated from other causes of internal derangement of the knee by a careful history and precise examination followed by appropriate investigations. Once the cause of the pain is determined, malalignment or malposition of the patella must be sought. The Merchant view of the patellar femoral joint is recommended in this regard to demonstrate patellar incongruence. The malalignment syndrome may or may not show the pathologic changes described as "chondromalacia" and respond particularly well after proximal patellar realignment...
