Background: Reconstruction of the anterior cruciate ligament (ACL) is one most common procedures in orthopaedic surgery. However, even with advances surgical techniques and implants, some patients still have residual anterolateral rotatory laxity after reconstruction. A thorough study anatomy region knee needed. Purpose: To determine measurements points attachments (ALL). Study Design: Descriptive laboratory study. Methods: Dissections structures were performed 20 human cadavers. After...
We present a new technique for the combined intra- and extra-articular reconstruction of anterior cruciate ligament. Intra-articular is performed in an outside-in manner according to precepts anatomic femoral tunnel technique. Extra-articular with gracilis tendon while respecting parameters origin insertion points path described knee anterolateral
Recent anatomic studies have confirmed the presence of a true ligament structure, anterolateral (ALL), in region knee. This structure is involved rotatory instability knee and might explain why some isolated reconstructions anterior cruciate result residual pivot shift. Therefore, when considering least invasive method for reconstruction this it important to identify corresponding bony landmarks on radiographic images.To establish femoral tibial ALL frontal lateral views.Descriptive...
No consensus exists regarding the anatomic characteristics of knee anterolateral ligament (ALL). A critical analysis dissections described in previous studies allows division ALL into 2 groups with similar characteristics. The presence considerable variability suggests that authors may not be referring to same structure.To perform a lateral dissection, by layers, seeking characterize variants for on knee. We hypothesized we would identify and these have distinct characteristics.Descriptive...
Background: Isolated reconstruction of the anterior cruciate ligament (ACL) does not reestablish normal knee biomechanics in cases associated injuries to anterolateral structures. Studies evaluating potential clinical effect (ALL) injury on treatment ACL are necessary validate findings biomechanical studies. Purpose: To evaluate outcomes and failure rate patients with without ALL diagnosed using magnetic resonance imaging. Study Design: Cohort study; Level evidence, 2. Methods: A prospective...
Background: Tibial tubercle osteotomy with concomitant distalization for the treatment of patellar instability remains controversial, as it may cause anterior knee pain and chondral degeneration. Purpose: To evaluate radiographic, clinical, functional outcomes in patients who had patella alta underwent tibial (TTO-d) well medial patellofemoral ligament reconstruction. Study Design: Case series; Level evidence, 4. Methods: Included this study were 25 (31 cases) (mean age at surgery, 28.7...
Abstract Objective: To assess the feasibility of entire micro fragmented adipose tissue knee injection procedure under local anesthesia. From subcutaneous harvesting and microfragmentation process to intrarticular injection. Methods: A patient with bilateral osteoarthritis underwent intra-articular Patient-related outcomes were collected before procedure, 12 months, 24 months follow-up. Womac, Koos, VAS recorded. Results: The visual analog scale, KOOS questionnaire, WOMAC score all improved...
The tibial tubercle-trochlear groove (TT-TG) is used as the gold standard for patellofemoral malalignment.To assess 3 patellar tendon-trochlear (PT-TG) angle measurement techniques and PT-TG distance (tendinous cartilaginous TT-TG) predictors of instability.Cohort study (diagnosis); Level evidence, 3.Three measurements were measured in 82 participants with instability 100 controls using magnetic resonance imaging (MRI). Measurement landmarks line tangent to posterior femoral condyles,...
Although the medial patellotibial ligament (MPTL) has been neglected regarding its function in patellar stability, recently, importance terminal extension and during flexion recognized. Indications for reconstruction of patellofemoral combined with MPTL are subluxation, instability, children anatomic risk factors knee hyperextension associated generalized laxity. We describe a quadricipital tendon autografts.
The current study analyzed changes in anterior cruciate ligament (ACL) and lateral collateral stress as a result of mechanical varus. In an exploratory pilot study, progressive varus was introduced to male finite element model the lower limb at different knee flexion angles. Nine situations were (combinations 0°, 30°, 60° 5°, 10° varus). ACL measured via section force, von Mises stress, fiber stress. Lateral force. For all 3 measures ACL, maximum values found extension, decreased with...
Background: The degree of knee hyperextension in isolation has not been studied detail as a risk factor that could lead to increased looseness or graft failure after anterior cruciate ligament (ACL) reconstruction. Purpose: To analyze whether more than 5° passive is associated with worse functional outcomes and greater primary ACL reconstruction hamstring tendon autograft. Study Design: Cohort study; Level evidence, 3. Methods: A cohort patients who had autografts was divided into 2 groups...
<h2>Abstract</h2> Combined injuries involving the anterior cruciate ligament (ACL) and posterolateral corner (PLC) occur in approximately 10% of complex knee injuries. The current tendency is to reconstruct both ACL structures PLC. In multiple ligaments, a potential problem reconstruction convergence tunnels lateral walls femur. As solution this problem, we propose combined technique for PLC with single tunnel femoral wall. ACL/PLC performed 2 semitendinosus tendons 1 gracilis tendon....
Septic arthritis is an infrequent disease although very important due to the possibility of disastrous outcomes if treatment not adequately established. Adequate information concerning epidemiology septic still lacking uncommon nature as well struggle establish a correct case-definition.To epidemiologically characterize population seen at Hospital das Clínicas, University São Paulo with diagnosis between 2006 and 2011.Sixty-one patients diagnosed knee 2011 were retrospectively evaluated.
