BACKGROUND: Knee osteoarthritis is a common and a disabling musculoskeletal disorder. Patients with knee osteoarthritis have activity limitations which are linked to the strength of the quadriceps muscle. Previous research reported that the relationship between quadriceps muscle strength and physical function is moderated by the level of knee joint frontal plane laxity. The purpose of the current study is to reexamine the moderation effect of the knee joint laxity as measured by stress radiographs on the relationship between quadriceps muscle strength and physical function...

Increase in the magnitude of lengthening during the limb lengthening procedure involves a high risk of decreased range of motion (ROM) in adjacent joints. Even though patients with achondroplasia can tolerate a relatively larger amount of lengthening owing to its inherent soft-tissue laxity, they often exhibit significant joint contractures during extensive lengthening. In the present study, we evaluated temporal changes in the ROM of the hip, knee, and ankle joints throughout the treatment period in 12 limbs of six patients with achondroplasia who had undergone extensive tibial lengthening...

BACKGROUND: Surgical treatment for shoulder instability generally involves labral repair with a capsular plication or imbrication. Good results are reported in both open and arthroscopic procedures, but there is no consensus on the amount or location of capsular plication that is needed to achieve stability and anatomic anterior, posterior, and inferior translation of the joint. QUESTIONS/PURPOSES: (1) What are the separate and combined effects of increasing plication magnitude and sequential additive plications in the anterior, posterior, and inferior locations of the joint capsule on glenohumeral joint translation in the anterior, posterior, and inferior directions? (2) What plication location and magnitude restores anterior, posterior, and inferior translation to a baseline level? METHODS: Fourteen cadaveric shoulders were dissected down to the glenohumeral capsule and underwent instrumented biomechanical testing...

Say-Barber-Biesecker-Young-Simpson's syndrome is one of the Ohdo-like syndromes. It is a very rare congenital condition that is commonly defined by its main clinical features that are blepharophimosis, ptosis, mental retardation, and delayed motor development. They are often associated with skeletal manifestations that are joint laxity, long thumbs and toes, and hypoplastic and/or dislocated patellae. To our knowledge, the available literature does not report any case where attention is drawn to management of skeletal aspect of this specific syndrome, especially surgically...

PURPOSE: Soft tissue balancing is of central importance to outcome following total knee arthroplasty (TKA). However, there are lack of data analysing the effect of tibial bone cut thickness on valgus laxity. A cadaveric study was undertaken to assess the biomechanical consequences of tibial resection depth on through range knee joint valgus stability. We aimed to establish a maximum tibial resection depth, beyond which medial collateral ligament balancing becomes challenging, and a constrained implant should be considered...

INTRODUCTION: Laxity in the trapeziometacarpal (TMC) joint is a debilitating condition usually affecting a young population. It can be treated operatively with ligament reconstruction. The purpose of this study was to determine the effectiveness of the Arthrex Mini TightRope® in reinforcing the stabilizing ligaments in an unstable TMC joint without decreasing the range of motion of the thumb. This method was compared with the "gold standard" published by Eaton and Littler in 1973...

Mucopolysaccharidosis IVA (MPS IVA, Morquio A syndrome) is an autosomal recessive disorder caused by the deficiency of N-acetylgalactosamine-6-sulfate sulfatase. Deficiency of this enzyme leads to the accumulation of specific glycosaminoglycans (GAGs), chondroitin-6-sulfate (C6S) and keratan sulfate (KS), which are mainly synthesized in the cartilage. Therefore, the substrates are stored primarily in the cartilage and its extracellular matrix (ECM), leading to a direct impact on bone development and successive systemic skeletal spondylepiphyseal dysplasia...

BACKGROUND: Total knee designs that attempt to reproduce more physiological knee kinematics are gaining attention given their possible improvement in functional outcomes. This study examined if a total knee designed for anatomic motion, where the soft tissue balancing was intended to replicate anatomical tibiofemoral contact forces, can more closely reproduce the laxity of the native knee. METHODS: In an ex-vivo setting, the laxity envelope of the knees from nine lower extremity specimens was measured using a rig that reproduced surgical conditions...

Background: Evaluation of shoulder joint laxity is an important component of the shoulder examination, especially in the setting of shoulder instability. Measures of generalized joint laxity, particularly the Beighton score, are often recorded and used to help make management decisions in these cases. However, no evidence is available to show that the Beighton score corresponds to specific measures of shoulder joint laxity. Purpose: To assess the correlation between the Beighton score and validated measures of shoulder joint laxity...

Femoral head and neck ostectomy (FHNO) is a salvage surgical procedure intended to eliminate hip joint laxity associated pain in the immature dog, or pain due to secondary osteoarthritis in the mature dog. The outcome of the procedure is associated with the size of the dog but the cause of a generally poorer outcome in larger breeds has not been determined. The objective of this study was to assess the long-term results of FHNO associated with unsatisfactory functional outcome by means of clinical examination and computed tomography (CT) scanning...

PURPOSE: Although soft tissue balancing is considered important for successful total knee arthroplasty (TKA), it is unclear whether the laxity and balance achieved intraoperatively change postoperatively. A recent study demonstrated anaesthesia significantly influenced knee joint laxity after TKA; however, there has been no comparison of the varus-valgus laxity immediately after TKA and in the postoperative period under the same anesthetic conditions. Therefore, quantitative stress arthrometric studies were conducted under identical conditions to identify changes in coronal ligament laxity after TKA spontaneously...

BACKGROUND: Instability is a common failure mode after total knee arthroplasty. There have been only a few methods to quantify anterior translation with fixed forces applied during surgery. The purpose of the study was to measure the anterior translation with a new device and to analyze the relationships between the amount of anterior translation and the joint gaps. METHODS: Fifty knees with medial osteoarthritis underwent surgery using a posterior-stabilized implant...

BACKGROUND: Joint hypermobility syndrome (JHS) is characterized by excessive connective tissue laxity manifest as joint hypermobility (JH) together with musculoskeletal symptoms. Previous studies have shown an association between JH/JHS and gastrointestinal symptoms, including irritable bowel syndrome (IBS), although its association with specific IBS subtypes is incompletely understood. We aimed to determine the prevalence of JH according to the subtypes of IBS, in particular IBS-C and IBS-D...
