“…Just recently Baumann et al reported on a study group of 77 skiers after tibial plateau fractures in a long-term follow-up study. It was found out that the PROM-score “forgotten knee score (FJS)”, which had been measured initially at arthroplasty, also significantly correlates with osteoarthritic radiologic knee joint degeneration in fracture cases [ 9 ].…”

“…In the past surgeon oriented outcome measurements such as the Tegner-, Lysholm- or Oxford-Score were widely accepted and established as the only clinical outcome measurement in knee surgery [ 4 , 5 ]. Other studies focused on return to sports after tibial plateau fractures [ 6 , 7 ] but overtime patient-reported outcome measurements have gained importance as well as tools for assessing the return to daily activity and working life [ 8 , 9 ].…”

BackgroundTibial plateau fractures requiring surgery are severe injuries of the lower extremity. Tibial plateau fractures have an impact not only on physically demanding jobs but notably on general professional life too. The aim of this study was to assess how the professional activity of patients will be affected after a tibial plateau fracture.Methods39 consecutive patients (ages 20–61 years) were retrospectively included in the study and were clinically examined at a minimum of 14 month postoperatively. Inclusion criteria were surgical treatment of tibial plateau fractures between November 2009 and December 2012. The clinical evaluation included the Lysholm score and the Oxford Knee Score. Fractures were classified and analyzed using the AO classification. Intensity of work was classified as established by the REFA Association. The patients themselves provided postoperative duration of the incapacity of work and subjective ratings.Results17 (43.6%) women and 22 (56.4%) men were examined with a mean follow-up of 29.7 ± 10.4 months (range 14–47). According to the AO classification there were 20 (51.3%) B-type-fractures and 19 (48.7%) C-type-fractures. The median incapacity of work was 120 days (range 10–700 days) with no significant differences between B- and C-type-fractures. Four (10.3%) patients reduced their working hours by 10.5 h per week on average. Patients with low workload (REFA 0–1, median incapacity of work 90 days, range 10–390 days) had a significant shorter incapacity of work than patients with heavy workload (REFA 2–4, median incapacity of work 180 days, range 90–700 days) (p < 0.05). The median Lysholm score decreased significantly from 100 points (range 69–100) before the injury to 73 points (range 23–100) at the time of the follow-up. All patients received postoperative physiotherapy (median 25 appointments, range 6–330), with a significant higher number of appointments for C-type-fractures than for B-type-fractures (p = 0.004).ConclusionA relationship was found between workload and the duration of incapacity of work after tibial plateau fractures. The post-injury shift to less demanding jobs and the reduction of working hours highlight the impact of a tibial plateau fracture on a patient’s subsequent physical ability to work.

“…Therefore, it is compiled for an older, physically less active patient population. However, recent studies have proven reliability in younger patients[ 12 , 13 , 17 - 19 , 34 ]. The FJS measures the patient’s ability to forget the joint in everyday life, which is seen as ultimate goal resulting in maximum patient satisfaction[ 11 ].…”

“…We found a mean FJS of 41.6 points in our patient population. Recently, Baumann et al [ 34 ] published a validation study on the FJS in long-term results of patients in a posttraumatic condition after tibial head fracture in 77 skiers. They found an increased joint awareness of 70.7 points in the FJS 9-13 years after injury.…”

BACKGROUND A fracture of the acetabulum is an uncommon, but serious injury. Established outcome tools do not reflect the patient’s perspective after fracture of the hip joint. Originally designed for post-arthroplasty patients, the Forgotten Joint Score (FJS) is a patient-reported outcome measurement (PROM) tool evaluating the disease-specific health-related quality of life (HR-QoL). AIM To validate the FJS in patients after acetabular fracture. METHODS In a prospective mono-centric cohort study, we evaluated 100 patients at mean 5.2 ± 3.6 years after a fracture of the acetabulum. The validation study followed the complete COSMIN checklist protocol. For calculation of convergent validity, we used the Tegner-Activity Scale, the Western Ontario and McMaster Universities Osteoarthritis Index, the EuroQol-5D, and a subjective rating of change as an anchor variable. RESULTS We confirmed good internal consistency with a Cronbach‘s alpha of 0.95. With an intraclass correlation coefficient of 0.99 (95%CI: 0.97, 0.99), test-retest reliability of the FJS was excellent. Correlation coefficients between the questionnaires were moderate to high ranging from |0.56| to |0.83| (absolute value). No relevant floor or ceiling effects occurred. Standard error of measurement was 3.2 and smallest detectable change (SDC) was 8.8. Thus, changes greater than 8.8 points between two assessments denote a real change in FJS. CONCLUSION The FJS is a valid and reliable tool for evaluation of patient-reported outcome in posttraumatic condition after acetabular fracture. The SDC indicating a real clinical improvement was 8.8 points in the FJS. We could confirm responsiveness of the FJS and found no relevant floor- or ceiling effects.

“…The total score derived from the individual questions ranges from 0 to 100 with high scores indicating good outcome, i.e., a low level of joint awareness. The questionnaire has shown good reliability and validity in psychometric analyses [6, 18] and has been validated in German [2, 3] and English [18].…”

Purpose The clinical benefits of total knee arthroplasty (TKA) are well defined, but little attention has been paid to the cross‐cultural variation. The objective of this study was to compare case mix and outcomes following TKA in Swiss and Scottish patients. Methods Data from local registries at a Swiss and a Scottish orthopaedic hospital were extracted to evaluate: (A) age, sex, body mass index (BMI), self‐reported health status (EQ‐5D), and joint awareness (Forgotten Joint Score‐12 (FJS‐12)) at pre‐surgery, (B) improvement in EQ‐5D and FJS‐12 scores from pre‐surgery to 1 year, and (C) patient satisfaction at 1 year. Results Data from 2075 Swiss and 994 Scottish TKA patients were available from the local registries. Swiss and Scottish patients differed in age (69.3 vs 68.8 years, p = 0.046), sex ratio (62.9% vs 56.9% women, p = 0.002) and BMI (29.6 vs 30.9, p < 0.001). At pre‐surgery, FJS‐12 scores were comparable (Swiss 12.1 vs Scottish 10.9, n.s.), but EQ‐5D scores were better in Swiss patients (0.52 vs 0.40, p < 0.001). Post‐operative improvement was greater in Switzerland for the FJS‐12 (+ 55.1 vs + 32.2, p < 0.001), but not for the EQ‐5D (+ 0.31 vs + 0.29, n.s.). The satisfaction rate was similar in both groups (88.3% vs 89.6%, n.s.). Conclusion Subtle cross‐cultural variation was evident in TKA case‐mix factors between the two countries. Satisfaction and improvement in health status were similar, while improvement in joint‐specific outcome was notably greater in Switzerland. Understanding cross‐cultural variability of the outcome has important implications when interpreting study and registry data from other countries and when counselling a patient in daily practice. Level of evidence Retrospective cohort, Level III.
