    INTRODUCTION We developed an accelerated clinical pathway involving outpatient surgery for patients undergoing total knee arthroplasty (TKA) who are healthy enough for early discharge.METHODS Between March 2014 and April 2015, 89 TKAs were performed at a single institution by a single orthopaedic surgeon. 31 patients met the inclusion criteria for the study. All patients received 2 g tranexamic acid and 750 mg cefuroxime sodium intravenously 30 minutes prior to surgery. A multimodal protocol for perioperative pain management was used for all patients.RESULTS 31 patients (three male, 28 female), with a mean age of 67 (range 49-78) years, who underwent TKA were enrolled in this study. The mean length of hospital stay was 28.7 (range 16-49) hours and mean duration of surgery was 92 (range 75-128) minutes. Combined spinal epidural anaesthesia was performed for 23 (74.2%) patients and general anaesthesia was used in 8 (25.8%) patients. Among the 31 patients, 23 (74.2%) patients were discharged within 23 hours of surgery.CONCLUSION Early discharge of patients following outpatient surgery for TKA was not associated with any procedure-related complications among the selected patients up to three months postoperatively.

    Comparison of patients undergoing revision total hip arthroplasty and patients undergoing re-revision

    - OBJECTIVE: The aim of this study is to compare the demographic, clini-cal, and surgical characteristics of patients who underwent revision hip replacement sur-gery and those who underwent re-revision sur-gery. The secondary outcome is the investiga-tion of the factors that play a role in estimating the time between primary arthroplasty surgery and revision surgery.PATIENTS AND METHODS: The patients who underwent revision hip arthroplasty in our clinic between 2010-2020, patients with at least 2 years of follow-up, and who underwent re-revision surgery if needed were included. Demographic and clinical data were investigated. RESULTS: Of the 153 patients who met the study criteria, 120 (78.5%) underwent revision (Group 1) and 33 (21.5%) underwent re -revi-sion (Group 2). The mean age of Group 1 was 53.5 (32-85), and of Group 2 was 67 (38-81) (p=0.003). In both groups, patients who un-derwent hip replacement due to fracture had more revisions and re-revisions (p=0.794). While 53.3 of the patients in Group 1 did not need additional implants, 72.7% of the pa-tients in Group 2 needed additional implants (p=0.010). Fracture-dislocation, fistula, and the need for debridement after the revision were statistically significantly higher in pa-tients who underwent re-revision. Harris hip scores (HHS) were statistically lower in pa-tients who went for re-revision. CONCLUSIONS: The need for reoperation in patients who have undergone revision total hip arthroplasty (THA) surgery is due to the fact that the patient's age is advanced and the indi- cation for surgery is a fracture. While the rate of fistula, fracture, dislocation, and debride- ment increases after re-revision surgeries, the HHS values that indicate clinical success also decrease. We believe that studies with larger participation and longer follow-up periods are needed to explain this issue better.

    Malignant transformation of monostotic fibrous dysplasia into angiosarcoma in the proximal tibia
    (Wolters Kluwer Medknow Publications, 2021-04-01) Yalçınkaya, Ulviye; YALÇINKAYA, ÜLVİYE; Narter, Selin; NARTER, SELİN; Bilgen, Muhammet S.; BİLGEN, MÜHAMMET SADIK; Yazıcı, Zeynep; YAZICI, ZEYNEP; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Genel Cerrahi Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Ortopedi Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.
    The majority of bone angiosarcomas are primary tumors while secondary angiosarcomas arise after radiation therapy or bone infarctus. This article presents a case of malignant transformation of monostotic fibrous dysplasia into angiosarcoma. An 80-year-old female presented with pain on right cruris. Radiological examination revealed a lesion with lytic areas and destruction of cortical bone on right tibia. Gross and histopathological examination showed two areas with an abrupt transition. The solid component was composed of curved, immature bony trabeculae in a fibroblastic stroma. The other component involved epitheloid cells forming slit-like vascular spaces. The diagnosis of angiosarcoma and fibrous dysplasia was given. Malignant transformation of fibrous dysplasia into angiosarcoma is extremely rare; as this is the sixth case in the existing literature. Prognosis of fibrous dysplasia is generally good and less than 1% of the patients develop a malignant tumor. Therefore, patients with fibrous dysplasia should be offered a life-long follow-up.
