Rim Plate Augmentation of the Posterolateral Bare Area of the Tibial Plateau Using a 3.5-mm Precontoured Locking Compression Plate: A Cadaveric Study.

Objective: To evaluate the effectiveness of an additional rim plate [3.5-mm precontoured locking compression plate (LCP)] for stabilizing the posterolateral fragment in lateral tibial plateau fractures.

Methods: Standard lateral locking plates [either a proximal tibial plate (PTP) or a proximal tibial locking plate (PTLP)] were applied to 40 matched pair knees from 20 fresh-frozen cadavers followed by the application of a secondary rim plate [variable angle LCP (VALCP)] posterior laterally.

Treatment of Kienböck's disease using a fourth extensor compartmental artery as a vascularized pedicle bone graft.

Background: Vascularized bone grafts for the treatment of Kienböck's disease may facilitate revascularization and remodeling of the avascular lunate. The aim of this study was to evaluate the radiological and clinical results obtained when a fourth extensor compartmental artery (ECA) bone graft was used to treat Kienböck's disease.

Methods: Between May 2009 and June 2012, 13 patients (6 men, 7 women) with Kienböck's disease were treated with placement of fourth ECA vascularized bone grafts.

Two- to Four-Year Follow-up Results of Total Knee Arthroplasty Using a New High-Flexion Prosthesis.

Purpose: The purpose of this study was to evaluate minimum 2-year follow-up results of total knee arthroplasty (TKA) performed using a new high-flexion prosthesis design (LOSPA).

Materials And Methods: The 2- to 4-year results of 191 consecutive TKAs (177 patients) with the LOSPA posterior-stabilized prosthesis were evaluated. The patients were assessed clinically and radiographically using the Knee Society scoring system (KSS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC).
