Patient Acceptable Symptom State for the Forgotten Joint Score in Primary Total Knee Arthroplasty

BackgroundIn order to better understand the clinical benefits of total knee arthroplasty (TKA) and improve the interpretability of the Forgotten Joint Score (FJS-12), the establishment of a meaningful change in score is necessary. The purpose of this study is to determine the threshold of the FJS-12 for detecting the patient acceptable symptom state (PASS) following primary TKA.MethodsWe retrospectively reviewed all patients who underwent elective, primary TKA and answered both the FJS-12 and the Knee Injury Osteoarthritis Outcome Survey, Joint Replacement KOOS, JR surveys 1-year postoperatively. The questionnaires were administered via a web-based electronic application. KOOS, JR score was used as the anchor. The anchor for PASS calculation should relate pain, physical function, and patient satisfaction. Two statistical methods were employed: (1) the receiver operating characteristic (ROC) curve point; (2) 75^th percentile of the cumulative percentage curve of patients who had the KOOS, JR score difference larger than the cut-off value.ResultsThis study included 457 patients. The mean 1-year FJS-12 score was 42.6 ± 27.8. The mean 1-year KOOS, JR score was 68.0 ± 17.2. A high positive correlation between FJS-12 and KOOS, JR was found (r = 0.72, P < .001) making the KOOS, JR a valid external anchor. The threshold score of the FJS-12 which maximized the sensitivity and specificity for detecting a PASS was 33.3 (AUC = 0.78, 95% CI [0.74, 0.83]). The cut-off value computed with the 75^th percentile approach was 77.1 (95% CI [73.9, 81.5]).ConclusionThe PASS threshold for the FJS-12 was 33.3 and 77.1 at 1-year follow-up after primary TKA using the receiver operating characteristic (ROC) curve and 75^th percentile approaches, respectively. These values can be used to assess the successful achievement of a forgotten joint.Level III EvidenceRetrospective Cohort Study.

Identifying Aseptic Revision Total Knee Arthroplasty Diagnoses That Achieve Minimal Clinically Important Difference and Patient Acceptable Symptom State

BackgroundMinimal clinically important difference (MCID) defines a meaningful clinical change in patient-reported outcome measures. Patient acceptable symptom state (PASS) provides a patient-reported outcome measures threshold value to indicate a satisfactory clinical state. MCID and PASS for revision total knee arthroplasty (rTKA) are ill-defined. Moreover, it is unknown whether diagnosis influences the likelihood of achieving MCID or PASS. The purpose of this study was to calculate MCID for aseptic rTKA and compare the percentage of patients achieving MCID and PASS per diagnosis.MethodsAn institutional registry of rTKA was used. First-time aseptic rTKA were included. Demographics, revision diagnosis, preoperative Knee Injury and Osteoarthritis Outcome Score, Jr (KOOS Jr), and 1-year postoperative KOOS Jr were recorded. The 1-year postoperative KOOS Jr PASS score was available. MCID was calculated using distribution-based methods. Three hundred fifty eight first-time aseptic rTKAs were analyzed. The 3 most common diagnoses were aseptic loosening (n = 156), instability (n = 109), and stiffness (n = 37).ResultsThe mean KOOS Jr 1-year postoperative MCID for rTKA was 10.3. Overall, 75.4% achieved MCID and 56.9% achieved PASS. The percentage of patients per diagnosis achieving MCID and PASS, respectively, were periprosthetic fracture (100, 44), aseptic loosening (94, 60), implant fracture (88, 63), stiffness (60, 38), instability (59, 61), polyethylene wear/osteolysis (57, 57), and metal allergy (44, 33).ConclusionAseptic rTKA MCID is 10.3 for KOOS Jr at 1 year postoperatively. rTKA outcomes vary depending on preoperative diagnosis. Even in diagnoses with a high proportion of MCID achieved, less than 2/3 of patients achieved PASS, suggesting rTKA provides noticeable improvement but may not return patients to a satisfactory state.     

Preoperative Osteoarthritic Grade Affects Forgotten Joint Status and Patient Acceptable Symptom State After Robotic Arm-Assisted Unicompartmental Knee Arthroplasty

BackgroundThis retrospective observational study was designed to investigate the association between radiographic Ahlbäck osteoarthritis (OA) grade and postoperative joint perception in a cohort of patients undergoing medial robotic arm-assisted unicompartmental knee arthroplasty (RA-UKA), using the Forgotten Joint Status and Patient Acceptable Symptom State (PASS) as outcomes.MethodsBetween January 2014 and May 2019, 660 patients (719 knees) underwent medial RA-UKA at 2 centers. Ahlbäck OA grade was measured on preoperative knee radiographs. Postoperatively, patients were administered the Forgotten Joint Score-12 (FJS-12) and 5-level Likert scale to assess patients’ satisfaction. Correlations were described among FJS-12, satisfaction, and Ahlbäck OA grade by means of logistic regression models.ResultsA total of 547 patients (602 knees) were assessed at a mean follow-up of 3.5 years (standard deviation 1.4). A total of 293 cases were graded as Ahlbäck 1 (Group A) and 309 knees were graded as Ahlbäck>1 (Group B). Statistically significant difference was detected in mean FJS-12 (P < .001), but not in the postoperative satisfaction level (P = .06) between the 2 groups. Patients in Group B had a significantly higher probability of attaining a “forgotten knee” after the operation, compared to Group A (P < .05). Cases in Group A had a significantly lower probability of achieving the PASS (P < .01).ConclusionPatients with higher grades of OA (Ahlbäck>1) were more likely to attain a “forgotten knee,” while patients with less severe OA (Ahlbäck 1) were less likely to achieve the PASS after RA-UKA. Although patients with less severe OA reported fairly good outcome, cases in which the results will be poorer are currently difficult to predict.     

良性疾病接受胰十二指肠切除术的临床分析

目的：了解胰十二指肠切除术中良性病例所占比例，分析其病变类型，探讨术前、术中诊断及其它治疗方式的可行性。方法：回顾性分析我院1996～2001年期间206例术前诊断为胰头或壶腹周围恶性肿瘤而作胰十二指肠切除术病例中，术后病理诊断为良性病变者23例的临床、病理资料。结果：术后病理检查发现慢性胰腺炎14例，胰头囊腺瘤2例，十二指肠乳头异位胰腺1例，十二指肠乳头良性腺瘤4例，胆总管下段炎性狭窄2例。良性病变占整个胰十二指肠切除术病例的11．2％。结论：在作胰十二指肠切除术的良性病变中慢性胰腺炎占大多数。术中取活检作冰冻切片病理检查是鉴别良、恶性病变的最有效方法。对这些良性病变可选择保守治疗或行较小的局部切除术。

Influence of Patient and Hospital Characteristics on Anesthesia Time in Medicare Patients Undergoing General and Orthopedic Surgery

Background: Procedure time is a clinically important variable that is often analyzed when studying quality and efficiency. Norms for procedure length have not been reported from Medicare data sets, nor has the influence of patient and hospital characteristics on procedure time been estimated using Medicare data.

Methods: The authors obtained Medicare claims on all patients aged 65-85 years who underwent general surgical and orthopedic surgical procedures in Pennsylvania. Anesthesia procedure time was estimated from anesthesia time units bills supplied from Medicare on 20 common general and orthopedic surgery procedures, and models to determine the influence of hospital and patient characteristics were developed.

Results: Of the 77,638 patients, 31,472 had general surgery and 46,166 underwent orthopedic procedures. The median anesthesia time for general surgery was 133 min, and for orthopedic surgery it was 146 min. After adjusting for principal procedure, hospital, and physiologic severity, covariates associated with increased anesthesia time included: multiple procedure on same day + 18.3 min (P < 0.0001); transfer-in + 6.7 min (P = 0.0002); black race + 5.5 (P < 0.0001); coagulation disorders + 4.9 (P = 0.0012); and paraplegia + 4.5 (P = 0.0006). Lower-income black patients had significantly longer procedure times than lower-income white patients (+ 7 min; P < 0.0001). Among the 15 hospitals with the largest black surgical populations, 5 hospitals had statistically significant procedure lengths for black versus white patients, ranging from + 9 to + 16 min.
