“…In addition, reporting of complication rates is highly variable [12,16,26]. In part, this can be attributed to varying methods of complication recording among authors [21], small samples sizes [4,20], limited followup [12,16,20], and the absence of a comparator group [2,11,13].…”

Total Knee Arthroplasty in the Elderly: Does Age Affect Pain, Function or Complications?

Cochrane

et al. 2013

“…In these kinds of cases, the HFKS shows that knee function is suboptimal in the high-function range. Furthermore, although pain and function of the knee are much improved after TKA according to currently used outcome tools [1,13,16], patient satisfaction is only approximately 85%. We believe the use of the HFKS allows identification of some of the unsatisfactory aspects of the outcome after TKA, which is a first step toward further enhancing the outcome of TKA.…”

“…We therefore developed a new scoring system for patients with higher levels of flexion to eliminate ceiling effects observed with current systems. Questions/purposes The purposes of this study were (1) to determine whether the high-flexion knee score eliminates the ceiling effect, (2) to assess the validity and responsiveness of the high-flexion knee score, and (3) to determine whether the high-flexion knee score can aid in differentiation of the knee status of patients at the ceiling level. Methods We prospectively studied 165 patients with 201 well-functioning knees who had undergone primary TKA.…”

A New High-flexion Knee Scoring System to Eliminate the Ceiling Effect

Lee

2012

Background Various scoring systems document improvement after TKA, but most are associated with a ceiling effect that may fail to distinguish between patients having different levels of knee function after TKA. We therefore developed a new scoring system for patients with higher levels of flexion to eliminate ceiling effects observed with current systems. Questions/purposes The purposes of this study were (1) to determine whether the high-flexion knee score eliminates the ceiling effect, (2) to assess the validity and responsiveness of the high-flexion knee score, and (3) to determine whether the high-flexion knee score can aid in differentiation of the knee status of patients at the ceiling level. Methods We prospectively studied 165 patients with 201 well-functioning knees who had undergone primary TKA. We obtained Knee Society scores, WOMAC scores, Feller scores, SF-36 scores, and high-flexion knee scores for all patients. The high-flexion knee score includes items that reflect knee function in the high functional range, such as sitting on or rising from the floor, squatting, or kneeling. We determined the ceiling effects and score distributions of various scoring systems. We performed a convergent validity test of the high-flexion knee score by correlation analysis with these various scoring systems. Responsiveness of the high-flexion knee score was assessed by correlation analysis of changes in various scoring systems. To determine whether the high-flexion knee score can aid in differentiation of knee status of patients at the ceiling level, relative responsiveness of the various scores in the ceiling versus below the ceiling range was determined. Results The high-flexion knee score showed no ceiling effect, whereas the other systems did. Addition of the highflexion knee score to the other scoring systems eliminated these ceiling effects and resulted in more normalized score distributions. The high-flexion knee score correlated (r = À0.77) with WOMAC in postoperative scores, and it also correlated with the changes in WOMAC (r = À0.69) and SF-36 physical functioning (r = 0.62).

“…Despite increasing demand for TKAs and cost-effectiveness of the procedure [11,16,17], a substantial number of patients who undergo a TKA are dissatisfied with the outcomes, with reported satisfaction rates varying between 75% and 89% [1,6,7,23,24,36,41,51], regardless of patient demographics or severity of disease.…”

Do Psychological Factors Predict Poor Outcome in Patients Undergoing TKA? A Systematic Review

Background A subgroup of patients undergoing TKA is unhappy with the outcome of surgery and preoperative psychological factors may play a role in their dissatisfaction. Questions/purposes We asked whether (1) psychological factors, as measured by preoperative self-reported questionnaires, predicted poor outcome after TKA, and (2) whether certain psychological factors examined predicted poor outcome better than others. Methods We performed a systematic review and metaanalysis of prospective observational studies published in MEDLINE, CINAHL 1 , EMBASE TM , and PsycINFO 1 databases from their date of inception to October 2013, augmented with a manual search of bibliographies. Study eligibility was performed according to an a priori protocol. Included studies were assessed for quality according to the Newcastle-Ottawa scale. Two reviewers independently performed the search, identified eligible studies, assessed their methodologic quality, and extracted data. Outcomes of interest included postoperative dissatisfaction, pain, or limited function of the patients.
