“…Comorbidities were recorded on standardized forms as being ''present'' or ''not present.'' Outcomes were measured using the Medical Outcomes Study SF-36 [24,25,33], the WOMAC [2,3,34], the functional and clinical components of the Knee Society Severity Index (KSS) [14], and the Lower Extremity Activity Scale (LEAS) [30]. The WOMAC and the SF-36 provide good estimates of patient outcomes following joint replacement [11,22,23], and the LEAS was developed specifically for use in the rev-TKA population [30].…”

The number of revision total knee arthroplasties (rev-TKA) is increasing every year. These cases are technically difficult and add considerable burden on the healthcare system. Many patients have concomitant low back pain that may interfere with functional outcome. We asked whether having low back pain at baseline would influence amount and rate of improvement on standardized outcomes measures after rev-TKA. We retrospectively reviewed 308 patients from prospectively collected data in a multicenter study. A minimum 24-month followup was available for 221 patients (71.8%). Patients with low back pain at baseline had worse scores on most instruments than their counterparts at baseline, 12 months postsurgery, and 24 months postsurgery. The data suggest concomitant back pain in patients undergoing rev-TKA affects their outcomes as measured by standardized instruments. Orthopaedic surgeons should counsel their patients with back pain regarding the possibility of slower or less complete recovery.

“…For practical reasons, if a conditionspecific outcome measure such as the WOMAC is to be used routinely by therapists in clinical practice, it must be as short and simple as possible. For these reasons, three reduced versions of the WOMAC have recently been proposed; 5,6,9 any advantages of one version over the others are unclear, however.…”

Purpose: To compare the original and reduced versions of the Berg Balance Scale (BBS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), as completed by patients following total hip arthroplasty (THA) or total knee arthroplasty (TKA), with respect to their potential utility in clinical and research settings. Method: Patients with THA (n ¼ 26) or TKA (n ¼ 28) were evaluated before and after 5 to 7 weeks' participation in a home-based exercise programme. They were assessed using the original versions of the BBS and the WOMAC; scores for the reduced versions of the BBS and the WOMAC were extracted from the original versions. Results: Good to excellent correlations (r b 0.80) were observed between the original and the reduced versions of the BBS and the WOMAC. The index of responsiveness, evaluated using standardized response means (SRM), was similar for the original and the reduced versions of the BBS and the WOMAC function sub-scale. Conclusions: The reduced versions of the BBS and the WOMAC provided similar information to the original versions and were equally responsive. These reduced versions comprise fewer questions and may be completed in considerably less time, which suggests that they may be advantageous for clinical and research use.

“…All patients underwent CT scans of the lower limb according to the standardized Perth protocol [12], and detailed measurement of coronal, sagittal, and rotational alignment was performed by a blinded independent assessor (CG, SH). Patient-reported outcomes were assessed using the Oxford Knee Score (OKS, 0-48 worst to best) [33], the reduced WOMAC (0-100 worst to best) score [42], the pain and function components of the Knee Society Score (KSS, 0-100 worst to best) [26], the Forgotten Joint Score (FJS, 0-100 worst to best) [4,31], EuroQol EQ-5D [11], and visual analog scales measuring pain at rest and when mobilizing (0-10 none to worst). Scores were measured preoperatively and at 6, 12, and 24 months postoperatively.…”

Background Neutral mechanical alignment (MA) in total knee arthroplasty (TKA) aims to position femoral and tibial components perpendicular to the mechanical axis of the limb. In contrast, kinematic alignment (KA) attempts to match implant position to the prearthritic anatomy of the individual patient with the aim of improving functional outcome. However, comparative data between the two techniques are lacking.Questions/purposes In this randomized trial, we asked: (1) Are 2-year patient-reported outcome scores enhanced in patients with KA compared with an MA technique? (2) How does postoperative component alignment differ between the techniques? (3) Is the proportion of patients undergoing reoperation at 2 years different between the techniques? Methods Ninety-nine primary TKAs in 95 patients were randomized to either MA (n = 50) or KA (n = 49) groups. A pilot study of 20 TKAs was performed before this trial using the same patient-specific guides positioning in kinematic alignment. In the KA group, patient-specific cutting blocks were manufactured using individual preoperative MRI data. In the MA group, computer navigation was used to ensure neutral mechanical alignment accuracy. Postoperative alignment was assessed with CT scan, and functional scores (including the Oxford Knee Score, WOMAC, and the Forgotten Joint Score) were assessed preoperatively and at 6 weeks, 6 months, and 1 and 2 years postoperatively. No patients were lost to followup. We set sample size at a minimum of 45 patients per treatment arm based on a 5-point improvement in the mean Oxford Knee Score (OKS; the previously reported minimum clinically significant difference for the OKS in TKA), a pooled SD of 8.3, 80% power, and a two-sided significance level of 5%. Results We observed no difference in 2-year change scores (postoperative minus preoperative score) in KA versus MA The institution of one or more of the authors (SWY, MLW, AB, BF) has received, during the study period, funding from Stryker (Kalamazoo, MI, USA) One or more of the authors (AB, MLW, BF) or a member of his or her immediate family, has or may receive payments or benefits, during the study period, an amount of less than USD 10,000 from Stryker.
