Effectiveness of Negative-Pressure Wound Therapy following Total Hip and Knee Replacements.

In this review, we assess the effects of negative-pressure wound therapy (NPWT) following primary hip and knee replacement surgery with a systematic review of randomized controlled trials (RCTs). We searched the Cochrane Bone, Joint, and Muscle Trauma Group's Specialized Registry on June 12, 2018; the Cochrane Central Register of Controlled Trials (CENTRAL, 2018, Issue 1); Ovid MEDLINE (1946-2018); and Embase (1980-2018). To identify RCTs, we combined a subject-specific search strategy with a sensitivity-maximizing version of the Cochrane highly sensitive search strategy.

High Medium-Term Survivorship of Cruciate-Retaining Total Knee Arthroplasties (110 Knees) for Valgus Deformity.

The main purpose of this article is to evaluate the clinical outcomes and survivorship of cruciate-retaining (CR) knee arthroplasties for valgus deformity. This article is retrospective consecutive series of 110 valgus knees using CR implants with a minimum 2-year follow-up. Deformity correction was achieved using stepwise sequential soft tissue releases (iliotibial band, popliteus tendon, lateral collateral release through sliver femoral condylar osteotomy).

Satisfactory medium-term outcomes with lateral condylar sliver osteotomy to correct valgus deformity in total knee replacements.

Purpose: To describe a surgical technique in correcting valgus deformity during total knee replacement and evaluate medium-term clinical outcomes.

Methods: This was a retrospective consecutive series of total knee replacement for severe valgus deformity of patients who underwent a lateral ligament complex release with a sliver osteotomy of the lateral femoral condyle with a minimum 1-year follow-up and recording objective and patient-reported outcome measures.

Results: Twenty-three patients (25 knees) were included with median follow-up of 5 years (range 1-15 years) and average age 67.

Degenerative meniscal tears of the knee: evaluation and management.

Meniscal injuries are among the most common orthopaedic injuries seen in knee clinics. Meniscal tears can occur as a result of acute injuries or chronic degeneration. However, the exact incidence of meniscal tears is difficult to ascertain because of the high number of asymptomatic tears and the high rate of degenerative tears in patients with advanced degenerative joint disease.

The efficacy of a "double-D-shaped" wire marker for radiographic measurement of acetabular cup orientation and wear.

Historically, wire markers were attached to cemented all-plastic acetabular cups to demarcate the periphery and to measure socket wear. The wire shape was either a semi-circle passing over the pole of the cup, or a circle around the cup equator. More recently, "double-D" shaped markers were introduced with a part-circular aspect passing over the pole and a semi-circular aspect parallel to the equatorial plane.
