Grade III valgus deformity (tibiofemoral alignment > 20°) is present in only 0.5% of patients receiving total knee arthroplasty. Furthermore, cases with a valgus deformity exceeding 40° are even rarer. Since they mostly affect elderly, polymorbid patients, successful outcome means a great challenge. We report on a case of a 90-year-old patient with a valgus deformity of 47°. The patient was preoperatively restricted to a wheel chair, unable to walk, and only able to stand for a few seconds. The maximal knee flexion was 100°, and there was an extension deficit of 15°. The WOMAC score was 91; the EQ-5D-5L Index was 0.048. She was treated with a constrained hinged prosthesis. Postoperatively, the axis was 6° valgus. After 3 months of rehabilitation, she was independent using a wheeled walker. The maximal flexion of the knee was 110° and there was no extension deficit. The WOMAC score was 45; the EQ-5D-5L Index was 0.813. This case demonstrates the possibility of a satisfactory result and an improvement in quality of life and mobility with a plausible timetable and with reasonable use of resources even in advanced age and severe valgus deformity.

Abstract Background The aim of this study was to compare the mid-term clinical and radiographic outcomes between medial-pivotal (MP) insert and double-high (DH) insert used under cruciate-retaining condition in ADVANCE® total knee arthroplasty (TKA). Methods The follow-up was conducted for 158 consecutive patients underwent unilateral ADVANCE® TKA from January 2011 to April 2014. 84 MP inserts and 74 DH inserts were used under cruciate-retaining condition. A 1:1 propensity score matching (PSM) analysis was performed between MP insert and DH insert to compare the clinical and radiographic outcomes. Results After a 1:1 PSM, 120 patients (60 pairs) were matched between MP insert and DH insert. The baseline demographic parameters and clinical scores were comparable between the two groups. The postoperative clinical outcomes at an averaged 8-year follow-up of both groups were significantly improved. The range of motion (ROM) of DH group was better than that of MP group and equivalent Knee Society Function Score (KSFS) between the two groups was found. However, the Knee Society Score (KSS), Western Ontario and McMaster Universities Arthritis Index (WOMAC) score and Forgotten Joint Score (FJS) of MP group were found to be significantly superior than those of DH group. Comparable complication rate and revision rate were observed between the two groups. The radiographic results were also equally good between MP and DH group. Conclusions Although the mid-term clinical and radiographic outcomes of DH insert are fairly good, the clinical scores of DH group were worse than those of MP group.

Sagittal Deformity

AbstractSagittal deformity of the knee is commonly corrected to neutral biomechanical axis (±3 degrees) during total knee arthroplasty (TKA), which is a widely accepted goal. Recent advances in surgical technology have made it possible to accurately plan and fulfill these goals. One of these is robotic-assisted TKA, which has been noted to help increase accuracy and precision of restoring a neutral mechanical axis. While there are data confirming the ability of robotic devices to better correct knee alignment than the manual technique, there is a lack of data concerning the use of the robotic devices in more complex cases, such as those in patients with severe varus or valgus deformity, as well as in flexion contractures. Therefore, the purpose of this case study is to present three cases in which the robotic-assisted TKA device was used to correct a severe varus and severe valgus deformities. Based on this case series, it should be noted that the robotic device can also help correct severe varus/valgus deformities and flexion contractures.

Purpose The aim of this study was to evaluate the efficacy of revision total knee arthroplasty (TKA) with cementless metaphyseal sleeves without stems either in the femoral or tibial side or in both. Methods In this retrospective study, 51 patients (51 knees) operated in the period 2010 to 2015 met the above-mentioned criteria and were invited to a medical examination including X-rays. Forty-six were available for the study. Mean follow-up was 37 months. Knee Society score (KSS) (objective knee score), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, and range of motion (ROM) were used as outcome scores and compared with baseline values. X-rays were also examined and compared with postoperative exams to evaluate the presence of loosening, radiolucent lines, and bone ingrowth. Satisfaction of the patients was also investigated using a linear scale from 1 to 10. Results KSS improved from 39 to 77 (p < 0.01); WOMAC score improved from 76 to 41 (p < 0.01). Twenty-four (52%) patients were satisfied, 15 (32%) were partially satisfied, and 7 (16%) were unsatisfied. ROM improved from 93 to 96 degrees (nonsignificant difference). X-rays showed no loosening of the implants, radiolucent lines in 4 patients (3 of them were asymptomatic) and bone ingrowth in 43 out of 46 patients. Conclusion In this short-term retrospective study, the use of sleeves without stem was a safe and effective procedure in revision TKA. We found a significant improvement in clinical results compared with baseline values and no signs of implant loosening. Level of Evidence Level IV, therapeutic case series.
