“…3). A WOMAC pain subscale greater than or equal to 10 has been shown to be a clinically accurate criterion in evaluating hip osteoarthritis as well as those patients undergoing nonarthroplasty hip surgery [9,13,25,27,39]. Patient-acceptable symptom state and minimal clinically important improvement are important factors when choosing a subjective outcome measure.…”

Background The Bernese periacetabular osteotomy (PAO) continues to be a commonly performed nonarthroplasty option to treat symptomatic developmental hip dysplasia, but there are few long-term followup studies evaluating results after PAO. Questions/purposes (1) What is the long-term survivorship of the hip after PAO? (2) What were the validated outcomes scores among patients who had PAO more than 14 years ago? (3) What factors are associated with longterm failure? Methods One hundred fifty-eight dysplastic hips (133 patients) underwent PAO between May 1991 and September 1998 by a single surgeon. Of those, 37 hips (34 patients [26%]) were lost to followup; an additional seven patients (5% [eight hips]) had not been seen in the last 5 years. The 121 hips (in 99 patients) were retrospectively evaluated at a mean of 18 years (range, 14-22 years).Survivorship was assessed using Kaplan-Meier analysis with total hip arthroplasty (THA) as the endpoint. Hips were evaluated for activity, pain, and general health using the UCLA Activity Score, modified Harris hip score, WOMAC, and Hip disability and Osteoarthritis Outcome Score (HOOS). Failure was defined as a WOMAC pain subscale score C 10 or having undergone THA. Hips were divided into three groups: asymptomatic (did not meet any failure criteria at any point in time), symptomatic (met WOMAC pain failure criteria at previous or most recent followup), and replaced (having undergone THA). A multinomial logistic regression model using a general estimating equations approach was used to assess factors associated with failure.Results Kaplan-Meier analysis with THA as the endpoint revealed a survival rate (95% confidence interval [CI]) of 74% (66%-83%) at 18 years. Twenty-six hips (21%) underwent THA at an average of 9 ± 5 years from the surgery. Sixty-four hips (53%) remained asymptomatic and did not meet any failure criteria at most recent followup. Thirty-one hips (26%) were symptomatic and considered failed based on a WOMAC pain score of C 10 with a mean ± SD of 11 ± 4 out of 20 at most recent followup. Although some failed initially by pain, their most recent WOMAC score may have been \ 10. Of the 16 symptomatic hips that failed early by pain (reported a WOMAC pain subscale score C 10 in the prior study), two were lost to followup, two underwent THA at 16 and 17 years, four still failed because of pain at most recent followup, and the remaining eight had WOMAC pain scores \ 10 at most recent followup. Asymptomatic hips reported better UCLA Activity Scores (asymptomatic: mean ± SD, 7 ± 2; symptomatic: 6 ± 2, p = 0.001), modified Harris hip scores (pain, function, and activity sections; asymptomatic: 80 ± 11; symptomatic: 50 ± 15, p \ 0.001), WOMAC Each author certifies that he or she, or a member of his or her immediate family, has no funding or commercial associations (eg, consultancies, stock ownership, equity interest, patent/licensing arrangements, etc) that might pose a conflict of interest in connection with the submitted article.

“…Due to the fact that many patients receive HRA to continue their highly active lifestyle, we thought it interesting to use the FHS, a performance-based assessment developed by Konan et al, 29 in order to delineate any difference in postoperative function between HRA and THA in our patient sample. The FHS involves a set of 5 tasks which end in a score for the patients hip in 3 domains (Function, Difficulty and Pain).…”

“…The FHS involves a set of 5 tasks which end in a score for the patients hip in 3 domains (Function, Difficulty and Pain). 29 The function score is calculated by using the patient’s objective performance in each task, while difficulty and pain scores are calculated from patient’s answers on a subjective 0–10 scale. A lower score is superior on the FHS scale.…”

“…Postoperative outcomes were quantified with several patient-reported outcome measures (PROMs) at the final study visit, including; Harris Hip Score (HHS), Functional Hip Score (FHS), Single Alpha Numeric Evaluation (SANE) and Forgotten Joint Score (FJS). 28–31 Outcome scores were collected by clinical appointment in 49 patients (79.0%) or phone interview in 13 patients (21.0%). Preoperative HHS as well as age, American Society of Anesthesiologists (ASA) score and body mass index (BMI) at time of surgery was retrospectively collected from a prospectively collected database in each patient for each procedure.…”

Hip resurfacing arthroplasty and total hip arthroplasty in the same patient: which do they prefer?

et al. 2019

Introduction: Hip resurfacing arthroplasty (HRA) is an alternative to conventional total hip arthroplasty (THA) with potential advantages of preserving femoral bone stock and the ability to participate in higher impact activities. This study compares outcomes, satisfaction and preference in patients who underwent HRA in 1 hip and THA on the contralateral side. Methods: 62 Patients with an HRA in 1 hip and a contralateral THA were retrospectively identified at 3 centres, consisting of 38 males and 24 females with 53 patients (85.5%) undergoing HRA first. A survey regarding satisfaction and preference for each procedure and outcome scores were obtained. Results: Patients were younger (51.5 vs. 56.6 years, p = 0.002) and had longer follow-up on the HRA hip (11.0 vs. 6.0 years, p < 0.001). HRA was associated with larger increase in Harris Hip Score from preoperative to final follow-up (35.8 vs. 30.6, p = 0.035). 18 Patients (29.0%) preferred HRA, 19 (30.6%) preferred THA and 25 (40.3%) had no preference ( p = 0.844). When asked what they would choose if they could only have 1 surgery again, 41 (66.1%, p < 0.001) picked HRA. Overall satisfaction ( p = 0.504), willingness to live with their HRA versus THA for the rest of their life ( p = 0.295) and recommendation to others ( p = 0.097) were similar. Conclusions: Although HRA is associated with risks related to metal-on-metal bearings, it showed greater increase in patient-reported outcomes and a small subjective preference amongst patients who have undergone both conventional and resurfacing arthroplasty.

“…However, they have significant drawbacks. These include "floor" and "ceiling" effects [10] such as the preoperative floor effects and postoperative ceiling effects seen in the WOMAC and SF-36 scores of patients undergoing total hip arthroplasty [11], and the ceiling effects seen in the Harris hip scores of patients undergoing total hip arthroplasty [12]. PROMs can also give mixed messages and can be negatively influenced by psychosocial factors [13,14], measuring the patient's perception of an outcome, rather than the true outcome.…”

Purpose We present the Aberdeen Weight-Bearing Test (Knee), an objective test specific for anterior knee discomfort assessed via load bearing. We assess its validity by performing it on normal subjects with no knee symptoms and subjects who had undergone anterograde tibial nailing. Methods Two scales are placed parallel on the floor with the dials concealed from the subject. The subject then kneels with one knee on each scale. The weight through each knee is recorded at 0, 15, 30, 45, and 60 s. The proportion of total body weight on each leg at each timepoint is calculated, and a ratio calculated from the values. A value of 1 equates to equal weight on each leg. The test was performed on 53 normal subjects and 38 subjects who had undergone tibial nailing. Results In the normal group, no significant difference in mean ratio of weight distribution (left:right) was seen at any timepoint (mean ratio range = 0.98-0.99, p value range = 0.18-0.64). In the tibial nail group, a difference was observed in mean ratio of weight distribution (injured:uninjured) favouring the uninjured leg, reaching significance at 0, 15, 30, and 45 s (mean ratio range = 0.88-0.94, p value range = 0.01-0.02). At 60 s, the mean ratio was 0.93 (p = 0.09). Conclusion The Aberdeen Weight-Bearing Test (Knee) is an objective, easily reproducible, specific test for anterior knee discomfort. It produces different results in individuals who have undergone anterograde tibial nailing compared to individuals with no knee symptoms.
