The prevalence of reversing of extension coronal deformity during flexion and how that may change the routine algorithm of soft tissue balancing in total knee arthroplasty (TKA) has not been published. We name this phenomenon, the reversing coronal deformity (RCD). We observed 12% (45 patients) of coronal deformities consistently reverse in flexion in the osteoarthritic knees before surgery. We conclude that RCD phenomena need to be addressed in every TKA and collateral ligament release need to be modified or avoided; otherwise postoperative flexion instability may be inevitable. Femoral rotation adjustment with posterior capsule release has to be attempted first in RCD patients. We define RCD as the reversing of a coronal extension deformity of more than 2° while the knee reaches 90°of flexion. That is to say a 2° or more varus knee in extension becomes a 2° or more valgus at 90° of flexion or vice versa. We retrospectively analyzed, in a multicenter study the alignment patterns of 387 (US = 270, UK = 117) consecutive computer navigated TKA subjects (June 2004–May 2008). 364/387 (US = 252, UK = 112) subjects were eligible for analysis (23 subjects had incomplete data: US = 18, UK = 5). The coronal deformity kinematics was observed during the range of motion and the range of medial /lateral deflections were analyzed.Introduction
Method
The patient-physician relationship is a complex interaction and the importance of effective communication is well documented. The importance and implications of effective physician-patient communication is highlighted by the implementation of Communication Skills as a core competency by ACGME. The purpose of this study was to evaluate anonymous surveys completed by orthopaedic clinic patients to assess their visit experiences and whether they would recommend their physician to a friend or family member. Data were collected from patients exiting SIUs Division of Orthopaedic Surgery outpatient clinics through the completion of an anonymous survey. The survey was distributed on a sample of days between 2002 and 2004 and again in 2009. Responders were asked to complete the survey and return it prior to leaving the office. Participating surgeons were aware of the project occurring but did not know the dates on which surveys would be collected from their clinic patients. All surveys were scanned for data entry and if there was any difficulty with the scanning process then the data was entered manually.Purpose
