Treatment of Recurrent Hemarthrosis Following Total Knee Arthroplasty Using Surgical Interventions

BackgroudRecurrent hemarthrosis following total knee arthroplasty (TKA) is a rare complication. Its pathophysiology and standard treatments have not yet been established. In this study, we report 7 cases of recurrent hemarthrosis after TKA in which failure of the initial conservative treatment was followed by angiographic embolization; in 1 of the 7 cases, arthroscopic electrocauterization was also performed after treatment failure with selective embolization.MethodsFrom January 2015 to May 2018, 7 patients visited our hospital due to recurrent hemarthrosis after TKA. Their medical records and serologic test results were reviewed to check for the presence of any bleeding disorder and history of anticoagulant use. Implant malalignment and instability were checked using X-ray. In all cases, the conservative treatment failed, so interventional angiography with selective embolization was performed, which was also followed by arthroscopic electrocauterization if the outcome was unsatisfactory.ResultsThe interval between TKA and the onset of hemarthrosis ranged from 3 to 76 months (average, 34.1 months). There was no coagulopathy and instability. All patients underwent conservative treatment at an interval of 4.3 months and the rate of relapse was 3.1 on average. On the interventional angiography, 6 cases showed vascular blush, and 1 case had pulsatile bleeding. The average duration for interventional angiography was 90.9 minutes. The average length of follow-up was 38.8 months. Embolization was successfully performed in 4 cases. In 2 of 3 failed cases, the symptoms improved without further treatment. In the remaining 1 failed case, the patient had a relapse of hemarthrosis, so an arthroscopic procedure was performed, which led to identification of the suspicious bleeding point by using preoperative angiographic findings. Electrocauterization was performed and active bleeding was stopped. All cases with recurrent hemarthrosis achieved improvement.ConclusionsInterventional angiography was used to aid in the diagnosis of recurrent hemarthrosis, and therapeutic selective embolization provided satisfactory clinical results. Even if selective embolization fails, interventional angiography may be helpful for further surgical procedures because it reveals vascular blush of a bleeding site. Therefore, interventional angiography and selective embolization should be considered to be a useful treatment for recurrent hemarthrosis after TKA.     

A case of delayed recurrent hemarthrosis after posterolateral reconstruction of the knee with a staple fixation at the lateral femoral epicondyle

We present a case of delayed recurrent hemarthrosis after posterolateral reconstruction of the knee with staple fixation of the tendon graft at the lateral femoral condyle. A 20-year-old man had undergone a reconstructive surgery of the knee with allogeneic Achilles tendon aimed to reinforce lateral collateral ligament and popliteofibular ligament. At 4 months after surgery, recurrent swelling of the operated knee after minor exertion developed. The radiographs showed prominent staples at the lateral side of lateral femoral condyle. The arthroscopy revealed that the staples were salient intra-articularly at lateral gutter of the knee, and the adjacent lateral capsule seemed abraded, through which the longitudinal fibers of iliotibial band were seen. Iatrogenic iliotibial band syndrome owing to the prominent staple was speculated. The staples were removed under arthroscopic guidance, and there has been no recurrence thereafter. A staple fixation over bony prominence is not advisable and the interference screw might be a better alternative method of fixation.     

Acute hemarthrosis: a histological, biochemical, and biomechanical correlation of early effects on the anterior cruciate ligament in a rabbit model

The early histological, biochemical, and biomechanical characteristics of the anterior cruciate ligament (ACL) were determined in a rabbit model of acute hemarthrosis. The ACLs of 19 rabbits were given seven consecutive daily knee injections of 2 ml of fresh autologous blood, and then compared to contralateral ACLs from control knees injected with 2 ml of lactated Ringer's solution daily for 7 days. The rabbits were then sacrificed. Synovial proliferation with iron deposition within synoviocytes was observed; however, the architecture of the ACL was maintained. Additionally, the total collagen content, collagenase activity, and biomechanical properties of the ACL were unaltered.     

Delayed recurrent hemarthrosis after staple fixation of tibial avulsion fracture of the posterior cruciate ligament: a case report

This study reports a case of unusual vascular complication related to the staple fixation for the tibial avulsion fracture of the posterior cruciate ligament (PCL). The patient, who experienced recurrent hemarthrosis 12 months after staple fixation for the avulsion fracture of the PCL, was successfully managed by removing the staple and suturing the bleeding focus of the popliteal artery. Injury to the popliteal artery by the prominent staples could be the culprit causing the recurrent hemarthrosis. This type of delayed popliteal artery injury should be kept in mind in open reduction and internal fixation for the tibial avulsion fracture of the PCL.     

Angiosarcoma after revision total knee arthroplasty

BackgroundHemarthrosis after total knee arthroplasty (TKA) is a relatively rare complication. Although most cases are effectively treated with conservative therapy, some cases require angiographic embolization or surgical intervention. Angiosarcoma is a rare malignant tumor derived from the vascular endothelium with neovascular hyperplasia and mainly arises in the skin and superficial soft tissue, and less frequently in deep soft tissue and bone. Although malignant neoplasms such as angiosarcoma in the vicinity of orthopedic implants were reported, the causal relationship between development of the malignant tumor and the orthopedic implant is widely debated in the literature.Case presentationWe report the case of a 68-year-old female with angiosarcoma that developed in the knee joint 2 years after revision TKA. The patient exhibited severe persistent bleeding, which reached 1000–1400 ml per day for 4 months. Histological analysis of the synovial tissue in the knee joint showed large cells with nuclear atypia. Immunohistochemical staining showed cells that were positive for CD31, CD34, and D2-40, and she was diagnosed with angiosarcoma. The patient underwent an amputation at the level of the thigh, and her general condition immediately improved after the operation. The patient did not exhibit bleeding from the site of amputation, and no local recurrence or distant metastases were detected 1 year after the amputation.ConclusionsTo the best of our knowledge, this represents the first report of angiosarcoma 2 years after revision TKA. Further careful follow up is needed, given the high-grade malignancy.     

Delayed diagnosis of a pseudoaneurysm with recurrent hemarthrosis of the knee joint

This is a case report of recurrent hemarthrosis of the knee joint over 3 months. The patient, a 47-year-old male had three arthroscopic procedures with multiple joint punctures over a 3-month-period prior to our initial consultation. The first procedure (arthroscopic synovectomy) was done for suspected infection following a series of hyaluronic acid injections. Recurrent hemarthrosis developed subsequent to this. Upon further evaluation, a pseudoaneurysm of the superior middle genicular artery was detected and successfully treated with selective angiographic embolization.     

Shoulder hemarthrosis due to a bleeding pseudoaneurysm

We describe a patient with advanced shoulder osteoarthritis who developed a spontaneous hemarthrosis due to a bleeding pseudoaneurysm. This rare cause of intra-articular hemorrhage is important to establish because specific treatment may offer relief and prevent further bleeding.     

Spontaneous hemarthrosis following thrombolytic therapy for acute myocardial infarction

We describe a 45-year-old man who developed a spontaneous hemarthrosis of his right knee following thrombolytic therapy with streptokinase and rtPA for acute myocardial infarction. Surprisingly, despite the wide use of thrombolytic therapy, only four cases of spontaneous hemarthrosis following thrombolysis have been previously reported. Prompt aspiration of the joint, after stopping anticoagulant therapy, and splinting will provide early diagnosis and may prevent further damage to the joint.
