Reports of fungal infection after total knee arthroplasty are extremely rare. In most reports, the infecting organism is a Candida species. The present report describes a case involving a 73-year-old immunocompetent woman who underwent total knee arthroplasty and presented one month later with signs of prosthetic infection. She underwent joint debridement and the fluid was sent for culture and sensitivity testing. The culture showed growth of Trichosporon asahii. The patient was administered intravenous and intra-articular injections of amphotericin B, followed by antifungal treatment with voriconazole for one year. At 26 months of follow-up, there was no evidence of infection and the patient was ambulating with a walker. To the authors’ knowledge, the present case is the first report of T asahii infection following knee replacement. Early detection, prompt institution of the appropriate antibiotics and regular follow-up are recommended.

Aims The primary aim of this study was to assess whether patient satisfaction one year after total knee arthroplasty (TKA) changed with longer follow-up. The secondary aims were to identify predictors of satisfaction at one year, persistence of patient dissatisfaction, and late onset dissatisfaction in patients that were originally satisfied at one year. Patients and Methods A retrospective cohort consisting of 1369 patients undergoing a primary TKA for osteoarthritis that had not undergone revision were identified from an established arthroplasty database. Patient demographics, comorbidities, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores, and Short Form 12 (SF-12) questionnaire scores were collected preoperatively, and one and five years postoperatively. In addition, patient satisfaction was assessed at one and five years postoperatively. Logistic regression analysis was used to identify independent predictors of satisfaction at one and five years. Results The overall rate of satisfaction did not change from one (91.7%, n = 1255) to five (90.1%, n = 1234) years (p = 0.16). Approximately half (n = 53/114) of the patients who were dissatisfied at one year became satisfied with their TKA at five years, whereas 6% (n = 74/1255) of those who were satisfied at one year became dissatisfied at five years. At one year, patients with lung disease (p = 0.04), with depression (p = 0.001), with back pain (p <  0.001), undergoing unilateral TKA (p = 0.001), or with a worse preoperative WOMAC pain score (p = 0.04) were more likely to be dissatisfied. Patients with gastric ulceration (p = 0.04) and a worse WOMAC stiffness score (p = 0.047) were at increased risk of persistent dissatisfaction at five years. In contrast, a worse WOMAC pain score (p = 0.01) at one year was a predictor of dissatisfaction in previously satisfied patients at five years. Conclusion Three groups of dissatisfied patients exist after TKA: ‘early’ dissatisfaction at one year, ‘persistent’ dissatisfaction with longer follow-up, and ‘late’ dissatisfaction developing in previously satisfied patients at one year. All three groups have different independent predictors of satisfaction, and potentially addressing risk factors specific to these groups may improve patient outcome and their satisfaction.

Objective To examine the association between single-surgeon learning curve and clinical outcomes following total knee arthroplasty (TKA). Methods This prospective study included the first consecutive patients undergoing TKA conducted by the same surgeon using the JOURNEY II Bi-Cruciate Stabilized Knee System (Smith & Nephew, Andover, MA, USA). Patients were assessed preoperatively, and at three months and one year postoperatively using Oxford Knee Score (OKS), Knee Society Score (KSS) and Knee Function Score (KFS). Outcomes were statistically analysed using sequential patient cohorts. Results Fifty patients were grouped into five sequential cohorts of 10 patients each. All patients showed significant improvement in postoperative knee scores following TKA. There was a trend toward increased improvement in knee scores in the later patient cohorts, at the three-month and 1-year follow-up. Conclusions The single-surgeon learning curve for minimally invasive TKA had a small effect on knee satisfaction scores at 3 months and 1 year following surgery in the first 50 consecutive cases, and only minor complications were encountered. A larger trial is necessary to draw generalizable conclusions regarding patient outcomes during surgeon learning.

A bi-cruciate stabilized (BCS) guided-motion total knee arthroplasty (TKA) design was introduced to improve knee kinematics by more closely approximating those of a normal knee. Previous studies have shown a high incidence of complications with this implant type, which led to recent modifications of the design by the manufacturer. The current study was undertaken to assess whether the use of a guided-motion knee system with an extension-first surgical technique is associated with a similar rate of short-term adverse outcome as reported in literature. The secondary aim was to assess if there were any differences between the original and modified implant designs. This retrospective study enrolled 204 consecutive patients (204 knees) undergoing TKA for osteoarthritis of the knee, with the first 154 receiving cemented Journey BCS I implants and the remaining 51 receiving cemented Journey BCS II implants when these became available. At follow-up, patients were tested for the presence of iliotibial friction syndrome (ITB-F) and midflexion instability. Knee score and function score were taken preoperatively, at one year, and at final follow-up. Outcome data between the two implant types were compared using the Mann-Whitney test. No patients were lost to follow-up. Mean follow-up time for the cohort was 24.5 ± 7.8 months (range, 12 - 36 months). There were no cases of stiffness (flexion < 90°). Incidence of ITB-F syndrome was considered low: three (2.0%) knees in the BCS I group and two (3.9%) in the BCS II group (p = 0.367). Five (2.5%) knees presented with mild instability in midflexion, three (2.0%) in the BCS I group and two (3.9%) in the BCS II group (p = 0.367). One patient with a BCS I implant required reoperation for aseptic loosening 23 months postoperatively. At one-year follow-up, there were no significant differences in range of motion, knee score, or function score. When used in combination with an extension-first surgical technique, good early functional results with an acceptable rate of complications were obtained with both the original and the updated Journey BCS knee implant. Long-term follow-up studies are needed to confirm our findings.

AbstractThis study aimed to evaluate whether manipulation under anesthesia (MUA) affect clinical outcome including range of motion (ROM) and patient satisfaction after total knee arthroplasty (TKA). It is hypothesized that MUA improves clinical outcomes and patient satisfaction after primary TKA. This retrospective study analyzed 97 patients who underwent staged bilateral primary TKA. MUA of knee flexion more than 120 degrees was performed a week after index surgery just before operation of the opposite site. The first knees with MUA were classified as the MUA group and the second knees without MUA as the control group. ROM, Knee Society Knee Score, Knee Society Functional Score, Western Ontario and McMaster Universities (WOMAC) score, and patient satisfaction were assessed. Postoperative flexion was significantly greater in the MUA group during 6 months follow-up (6 weeks: 111.6 vs. 99.8 degrees, p < 0.001; 3 months: 115.9 vs. 110.2 degrees, p = 0.001; 6 months: 120.2 vs. 117.0 degrees, p = 0.019). Clinical outcomes also showed similar results with knee flexion during 2 years follow-up. Patient satisfaction was significantly high in the MUA group during 12 months (3 months: 80.2 vs. 71.5, p < 0.001; 6 months: 85.8 vs. 79.8, p < 0.001; 12 months: 86.1 vs. 83.9, p < 0.001; 24 months: 86.6 vs. 85.5, p = 0.013). MUA yielded improvement of clinical outcomes including ROM, and patient satisfaction, especially in the early period after TKA. MUA in the first knee could be taken into account to obtain early recovery and to improve patient satisfaction in staged bilateral TKA.
