Radiographic sign of persistent soft-tissue imbalance after knee replacement.

چکیده
We report on the radiological findings in a series of 871 consecutive primary condylar knee replacements followed up for an average of four years. A new radiological sign has been identified, consisting of a smoothly tapering wedge of cement visible beneath the horizontal portion of the tibial component on the anteroposterior radiograph. This was found in 25.4% of our cases and appears to indicate a persistent soft-tissue imbalance following condylar arthroplasty of the knee. The cement-wedge sign was associated with a highly significant increase in radiolucent lines at the tibial cement-bone interface.

Soft-tissue balance and recovery of proprioception after total knee replacement.
Decreasing proprioception of the knee is multifactorial and is a function of age and degenerative joint disease. Soft-tissue release during total knee replacement may have an influence. We have quantified soft-tissue imbalance at the time of knee replacement and attempted to eliminate it at full extension, using established methods. We studied the influence of residual soft-tissue imbalance on ...
متن کاملPreoperative radiographic valgus alignment predicts the extent of lateral soft tissue release and need for constraint in valgus total knee arthroplasty
Background In total knee arthroplasty (TKA) for valgus knees, the decision to use a constrained implant is often made intraoperatively depending on the extent of soft tissue releases performed and residual soft tissue imbalance. The purpose of this study is to determine if preoperative radiographic criteria of valgus knees can predict the extent of soft tissue releases required and the level of...

Ochronosis or black joints disorder is a rare autosomal recessive disorder caused by deficiency of homogentisic acidoxidase. Orthopaedic manifestations are common and mostly involve spine and large joints such as knee and hip.Arthropathy is progressive and will eventually leads to arthroplasty. Not being familiar with this disorder might lead todevastating complications. We present a 57 year-ol...
متن کاملEpithelialization Over a Scaffold of Antibiotic-Impregnated PMMA Beads: A Salvage Technique for Open Tibial Fractures with Bone and Soft Tissue Loss When all Else Fails
The management of soft tissue defects in tibial fractures is essential for limb preservation. Current techniques are not without complications and may lead to poor functional outcomes. A salvage method is described using three illustrative cases whereby a combination of flaps and antibiotic-impregnated polymethylmethacrylate beads are employed to fill the bony defect, fight the infection, and...
متن کاملA New Physical Examination Technique for Evaluating Valgus Knee Deformity: Swing Test
Valgus deformity can exist during knee flexion besides extension, which could lead to patellofemoral joint instability and soft tissue imbalance in the flexion gap, and thus complicate the surgical procedures. Valgus deformity during knee flexion can be measured by radiographic analysis using long‐film radiograph and computed tomography (CT) scans.[4] It usually results from a bone defect in th...
