Background
Postoperative suction drains are used after total knee arthroplasty to avoid intra-articular hematoma formation although they can increase blood loss due to a negative suction effect. The use of tranexamic acid to reduce blood loss may nullify this. The aim of this study was to compare outcomes in patients undergoing total knee arthroplasty with or without drains and to analyze whether the drain's diameter also has an impact.
Methods
This is a prospective randomized study of patients undergoing unilateral total knee arthroplasty performed by a single surgeon. The study population was divided into three groups (A, 10G drain; B, 12G drain; and C, no drain). Pain, blood loss, swelling, wound-related complications, functional outcomes and questionnaire-based outcomes were assessed postoperatively.
Results
Each group had 35 patients comparable in most demographic and pre- and intraoperative characteristics. During the first 6 hours postoperatively, opioid consumption was significantly higher when the drain was not used (
p
= 0.036). At 3 months postoperatively, new Knee Society Score (NKSS) was highest with the use of 12G drain (
p
= 0.018). However, NKSS at 1 year was comparable across the three groups. With the use of tranexamic acid, blood loss and incidence of soakage of dressing were unaffected by the presence or absence of a drain. The calf girth, suprapatellar girth, soakage of dressing and range of motion were comparable in all three groups. There was no incidence of surgical site infection or deep vein thrombosis.
Conclusions
Presence of a suction drain significantly reduces opioid consumption during the first 6 hours after total knee arthroplasty. Use of a drain made no difference to the functional outcome at 1 year postoperatively. With the use of tranexamic acid in total knee arthroplasty, the total blood loss and the requirement of blood transfusion were unaffected by the presence or absence of closed suction drainage or by the bore of the drain used. The clinical parameters such as swelling, range of motion, infection and deep vein thrombosis also remained the same.
Wilson's disease (WD) is a rare inherited disorder of copper metabolism. It chiefly has hepatic, neurological and ophthalmic manifestations. Although osteoporosis, rickets and early arthritis are common features of WD, they are under-recognized. Musculoskeletal manifestations very rarely lead to diagnosis of the disease. Here we present a case of a 12-year-old girl who presented with a 3-month-old pathological fracture of neck of femur. WD was diagnosed on investigating the cause of the pathological fracture, which was managed by performing a conventional McMurray's intertrochanteric osteotomy. At 6 months follow up, fracture had united and patient was able to ambulate with support. WD can be a rare cause of pathological fracture. A high index of suspicion must be maintained in patients of pathological fracture presenting with associated neuropsychiatric or hepatic manifestations.
Combined therapy of NSAIDs and bisphosphonates shows excellent results over a period of one year. Joint-preserving surgeries are effective even in Koshino stage 3 SPONK.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
