Total joint arthroplasty in haemophilia

In severely affected haemophilic patients arthropathy is a common problem which can lead to considerable pain and functional deficit. Surgical management, including total joint arthroplasty, can be undertaken if conservative management fails. A search of the literature showed that a number of studies describing the use of total knee arthroplasty (TKA) and total hip arthroplasty (THA) in haemophilia have been published, whereas shoulder, elbow and ankle arthroplasties are confined to case reports. This paper reviews the functional outcome of arthroplasty in the different joints, the postoperative and long-term complications, and the impact of HIV. Although complications are commonly described and the surgery is technically demanding, the results suggest that arthroplasty, particularly of the hip and knee, can be a valuable option in the management of severe haemophilic arthropathy.     

Preliminary results for the use of knee mega‐endoprosthesis in the treatment of musculoskeletal complications of haemophilia

Complications of haemophilia in the knee region are rare and difficult to treat. Use of surgical treatments such as total knee arthroplasty cannot satisfactorily restore knee function in patients with these complications, which include massive haemophilic pseudotumour, fracture around the knee and haemarthrosis. To analyse the postoperative results of patients suffering from complications of haemophilia and treated with a knee mega‐endoprosthesis, to discuss and compare this type of surgical management with other types of treatments used in similar cases. We retrospectively analyse the surgical results of patients who were treated with a knee mega‐endoprosthesis for complications of haemophilia. Three severe haemophilic arthritic knees, of which two were combined with femoral condylar fractures, were treated in a one‐stage surgery, and another two knees which presented with massive haemophilic pseudotumours and bony defects were treated in a two‐stage operation. Mean age at time of surgery was 28.5 years old and mean follow‐up time was 22.8 months; the mega‐endoprosthesis surgery was successfully performed in four cases and the mean range of motion increased from 29.5° preoperatively to 96.75° postoperatively. The Knee society score function score value increased from 25 to 82.5. One knee was amputated because of uncontrollable recurrent haemorrhage. Roentgenograms did not show any signs of loosening of the prostheses. Use of Mega‐endoprosthesis in the treatment of complications of haemophilia can offer patients suffering from massive pseudotumours with bone defect, severe contracture knee haemophilic arthritis and fractures around a haemophilic knee a viable treatment option.     

Total joint arthroplasty: the final solution for knee and hip when synovitis could not be controlled

Summary.  In severely affected haemophilic patients knee and hip arthropathy is a common problem, which can leads to considerable pain and functional deficit. Surgical management, including total knee and hip arthroplasty, can be undertaken if conservative management fails. This paper reviews the functional outcome of arthroplasty in the knee and hip, the postoperative and long-term complications, and the impact of HIV. Although complications are commonly described and the surgery is technically demanding, the results of the author of this paper and the review of the literature suggest that arthroplasty of the hip and knee can be a valuable option in the management of severe haemophilic arthropathy.     

Haemophilic; Arthropathy: Assessment of Quality of Life After Total Knee Arthroplasty

The goal of this study was to examine how the known effects of total knee arthroplasty (TKA) on clinical outcome parameters translate into improved quality of life, as measured with validated condition-specific and generic questionnaires (Knee Society Score, WOMAC, SF-12, transition questions), addressing physical, mental and social health. Eleven patients (13 knees) undergoing TKA from 1986 to 1994, with the diagnosis of severe haemophilic arthropathy of the knee, were followed-up over a 4-year period on average. TKA was found to reduce the burden of disease to levels similar to patients with osteoarthritis undergoing hip arthroplasty. Clinical and functional improvement after TKA translated into a substantial and significant increase in quality of life and patient satisfaction, found in objective as well as in patient-perceived measures. However, the physical functional ability did not reach the same level as in the corresponding population not affected by haemophilia, due to residual symptoms and impairment of other joints.

Aspects of current management: orthopaedic surgery in haemophilia

Summary. If continuous prophylaxis is not feasible due to expense or lack of venous access, we must aggressively treat major haemarthroses (including arthrocentesis) to prevent progression to synovitis, recurrent joint bleeds, and ultimately end‐stage osteoarthritis (haemophilic arthropathy). For the treatment of chronic haemophilic synovitis, radiosynovectomy should always be indicated as the first procedure. If, after three procedures with 6‐month interval, radiosynovectomy fails, an arthroscopic synovectomy must be indicated. Between the second and fourth decades, many haemophilic patients develop joint destruction (arthropathy). At this stage possible treatments include alignment osteotomy, arthroscopic joint debridement, arthrodesis (joint fusion) and total joint arthroplasty. For the hip press‐fit uncemented components (hemispherical acetabulum, flanged femoral stem, metal‐to‐polyethylene) are recommended whilst for the knee a posterior‐stabilized (PS) cemented design is advised. Muscular problems must not be underestimated in haemophilia due to their risk of developing compartment syndromes (which will require surgical decompression) and pseudotumours (which will require surgical removal or percutaneous treatment). Regarding patients with inhibitors, the advent of APCCs and rFVIIa has made major orthopaedic surgery possible, leading to an improved quality of life for haemophilia patients. Concerning local fibrin seal, it is not always necessary to achieve haemostasis in all surgical procedures performed in persons with haemophilia. However, it could be a good adjunct therapy, mainly when a surgical field potentially will bleed more than expected (i.e. patients with inhibitors), and also in some orthopaedic procedures (mainly the surgical removal of pseudotumours).     

Is joint effusion on MRI specific for haemophilia?

Magnetic resonance imaging (MRI) scores for haemophilic arthropathy are useful for evaluation of early and moderate arthropathy. The most recent additive International Prophylaxis Study Group (IPSG) MRI scale for haemophilic arthropathy includes joint effusion. However, it is unknown whether joint effusion is haemophilia specific. Correct interpretation of joint effusion is needed for outcome assessment of prophylactic therapies in haemophilia care. The aim of this study was to compare joint effusion on MRI between young adults with haemophilia and healthy controls. MRI's of both knees and ankles of 26 haemophilic patients (104 joints) and 30 healthy active men (120 joints) were assessed. Scans in both groups were performed in 2009/2010 and 2012 respectively. Joint effusion was measured and scored according to the MRI atlas referred by the IPSG MRI scale for haemophilic arthropathy. Median age of haemophilic patients and healthy controls was 21 and 24 years respectively. In haemophilic patients 23% of knees and 22% of ankles showed joint effusion. Healthy controls had significantly more positive scores for knee effusion (67%, P < 0.01) and a comparable scores for effusion in the ankle (17%). Joint effusion according to criteria of the IPSG MRI scale was observed significantly more often in knees of healthy controls, while findings in ankles were similar. These data suggest that joint effusion in knees and ankles is not haemophilia specific. Inclusion of joint effusion in the MRI scale is expected to reduce its specificity for haemophilic arthropathy.     

Synovectomy for haemophilic arthropathy: 6–21 years of follow-up in 16 patients

Abstract. Objectives . To assess the efficacy of synovectomy in reducing recurrent haemarthroses and joint pain in patients suffering from haemophilic arthropathy. Moreover, to study whether synovectomy could improve joint mobility or postpone progression of joint destruction. Design . A retrospective study was conducted addressing joint-related symptoms and findings, and the need of orthopaedic surgery during follow-up. Setting . Oslo Sanitetsforenings Rheumatism Hospital/The National Hospital, the National Centre for Orthopaedic Surgery for approximately 180 Norwegians suffering from severe congenital coagulation deficiencies. Subjects . Twelve patients with haemophilia A, two patients with von Willebrand's disease and two patients with factor VII deficiency in which 21 synovectomies (nine knees. six ankles and six elbows) were performed. Main outcome measures . Joint pain, joint mobility, frequency of haemarthroses and radiographic joint scores at follow-up were compared to preoperative figures, and the number of joints in need of total joint replacement or arthrodesis was evaluated. Results . Synovectomy proved efficacious in reducing recurrent haemarthroses and joint pain in all patients. The total range of motion was not improved, but correction of extension deficiency of the knee was accomplished. The progression of arthropathy was not arrested by synovectomy as judged by the radiographic assessment; and in four patients arthroplasty of the knee, and in two patients arthrodesis of the ankle, had been performed. A major wound haemorrhage and subsequent wound rupture was seen in one patient who developed high-titred neutralizing antibodies to factor VIII. Conclusions . Synovectomy for haemophilic arthropathy is safe and efficacious in reducing recurrent haemarthroses and joint pain. Synovectomy should not be performed to improve joint mobility. The progression of the arthropathy is not arrested, and subsequently many patients will be candidates for arthroplasty or arthrodesis.     

Perioperative clotting factor replacement and infection in total knee arthroplasty

Total knee arthroplasty, or replacement (TKR), is now the most commonly performed surgical procedure performed in adults with haemophilia. It is indicated when end-stage haemophilic arthropathy results in intractable pain and reduced function. In patients with haemophilia, however, there has always been a concern about the high risk of infection, which carries with it potentially catastrophic consequences. The aims of this study were to review the case series of TKR for haemophilic arthropathy published in the medical literature, comparing the published infection rates and the differing clotting factor replacement regimes employed. Nineteen retrospective case series were identified; representing 556 TKR's in 455 patients with an overall infection rate of 7.9%. Case series which maintained a high level of clotting factor replacement throughout the first two postoperative weeks, however, had an infection rate of 2.15%, significantly lower than that of case series using the clotting factor replacement regime currently recommended in the World Federation of Hemophilia guidelines (9.22% P = 0.00545). We believe this study supports the use of a high level clotting factor replacement regime, replacing clotting factors to maintain them at a higher level for a longer period of time than currently recommended in international guidelines.     

Correction of fixed contractures during total knee arthroplasty in haemophiliacs

Encouraging clinical experience has increased the indications for prosthetic knee arthroplasty in haemophiliacs. The medical status, physical disability, age and projected activity levels are the major factors in determining treatment for the patient with unilateral or bilateral haemophilic arthropathy of the knee. In more severely involved knees of patients with haemophilia, flexion contracture is a common deformity. In addition, valgus, external rotation deformity and posterior subluxation of the tibia may exist. The surgeon must have the expertise and experience to correct these deformities sufficiently when performing a total knee arthroplasty. A properly performed soft-tissue release which achieves balance between the medial and lateral ligamentous structures and posterior capsule can provide stability to the knee with a semiconstrained prosthesis. In cases with severe deformity requiring resection of the posterior cruciate ligament a posterior cruciate substituting prosthesis may be necessary.     

Force fluctuations during the Maximum Isometric Voluntary Contraction of the quadriceps femoris in haemophilic patients

In the general population, the degenerative processes in joints are directly related to adult age, and osteoarthrosis represents the most frequent musculoskeletal alteration. In the haemophilic patient, the degenerative processes in the joint begin at very early ages, and are directly related to musculoskeletal bleeding episodes, which are occasionally subclinical and constitute haemophilic arthropathy. In the haemophilic patient, arthropathy constitutes the most frequent, severe and disabling pathology, and its assessment includes muscular force-related parameters. We have studied the value of Maximum Isometric Voluntary Contraction in the quadriceps femoris of 46 subjects, 28 haemophiliacs (16 severe, eight moderate and four mild) and 18 healthy individuals with a view to establishing appropriate values of force and to restoring physical therapy recommendations. The maximum force values were significantly greater (P < 0.001) in the healthy individuals group. The mild haemophiliacs group also presented significant differences of force (P < 0.05) in relation to the severe and moderate haemophilic patient groups. The mild and severe haemophilia patients presented greater fluctuations of force (P < 0.001) than the control group, the haemophilia group have a minor skill to produce constant force. The seriousness of the arthropathy in the knee is directly related to diminished values of maximum force. Our work evidences that patients with severe haemophilia present a greater degree of arthropathy in relation to moderate and mild haemophilia patients. Haemophilic arthropathy is associated with muscular atrophy and strength deficit. In haemophilic patients, the deficit of maximum force and the presence of fluctuations may suggest an increased risk of bleeding during physical activities and the need to programme specific physical therapy guidelines which increase muscular power through resistance training.     

Shoulder hemiarthroplasty to manage haemophilic arthropathy: two case studies

Bleeds within the shoulder joint can lead to significant joint destruction and may have associated pain, decreased range of movement (ROM), and impaired function. Conservative management should involve prompt administration of Factor VIII and physiotherapy to address all surrounding structures so as to minimize further damage. If conservative management fails to relieve severe, unremitting shoulder pain in the presence of underlying arthropathy, then arthroplasty may be considered. Outcomes of arthroplasties performed for osteoarthritis and rheumatoid arthritis appear favourable. Few articles, however, have addressed shoulder arthroplasty to manage haemophilic arthropathy, and no reports have documented the rehabilitation process. Three hemiarthroplasties were performed at the Royal Brisbane and Women's Hospital on two men with haemophilia. There were no surgical or postoperative complications. Rehabilitation included intensive physiotherapy. The results in each case revealed a decrease in pain, and an increase in ROM and function postoperatively. These findings suggest that hemiarthroplasty with postoperative physiotherapy may be a feasible option to manage severe, chronic and progressing shoulder pain as a result of haemophilic arthropathy of the shoulder.     

Viscosupplementation in haemophilic arthropathy: a long-term follow-up study

Haemophilic arthropathy is the most common clinical manifestation of haemophilia, secondary to recurrent haemarthroses and chronic synovitis. Modern bleeding-preventing drugs have limited significantly the incidence of severe arthropathy, and primary approach is usually conservative. Use of intra-articular injections of hyaluronan acid is considered one of the most efficient treatments for early stages of articular degenerative diseases. Assessment of long-term effectiveness of intra-articular administration of hyaluronic acid (HA) in knees, ankles and elbows of patients affected by haemophilic arthropathy was done for 46 patients (10 elbows, 24 knees and 25 ankles) affected by haemophilic arthropathy. They received injections of HA and were evaluated with Visual Analogue Scale, Short Form-36, World Federation of Haemophilia score and Petterson score with a 6-year mean follow-up. Most of the patients showed improvement in pain relief and functional recovery without any complications: only a limited number of patients (8.6%) found poor results, undergoing surgery or other further treatments in the follow-up period for persistent pain or limitation. Viscosupplementation is an effective therapeutic strategy in early stages of haemophilic arthropathy, with no complications and long-term good clinical results.     

Knee joint arthroplasty in a patient with haemophilia A and high inhibitor titre using recombinant factor VIIa (NovoSeven®): a new case report and review of the literature

Elective orthopaedic surgery is regularly withheld from patients with haemophilia and high inhibitor titre despite the presence of severe arthropathy and urgent medical need. A knee joint arthroplasty was performed in a patient with severe haemophilia A and a high inhibitor titre using recombinant factor VIIa (rFVIIa) as the sole coagulation factor. There was no abnormal bleeding during surgery although an increased blood loss through surgical drains did occur during the first 6 h postoperatively. Rehabilitation was started on day 1 and continued for 3 months. Walking commenced on day 4. After 1 year of follow-up, the clinical outcome of surgery was considered excellent with no pain, knee mobility at 0-5-90 degrees, and an International Knee Society score of 95/100. No rFVIIa-associated side-effects or thrombotic complications were reported. In conclusion, knee joint arthroplasty is now an option for haemophilia patients with a high inhibitor titre. An international review of all available data on elective orthopaedic surgery in inhibitor patients is required so that the optimal treatment regime can be defined and the short- and long-term risk-benefit ratio of surgery compared to that of noninhibitor patients.     

Sonography for assessment of haemophilic arthropathy in children: a systematic protocol

Radiological imaging of joints in children with haemophilia is important to detect abnormalities, grade their severity and monitor the effects of treatment. Scoring systems for staging haemophilic arthropathy have been developed based on plain film or magnetic resonance imaging (MRI) findings. Radiographs alone may be inadequate for evaluating joint disease in children with haemophilia on prophylaxis while MRI may be difficult to access and require the child to be sedated. Sonography can be a useful complementary modality in the evaluation of haemophilic arthropathy that is readily available and does not require the child to be sedated. In this paper, we briefly review the current imaging scales available for the assessment of haemophilic arthropathy and present a systematic protocol for sonographic assessment of the knee and ankle in haemophilic children along with examples of findings in joint effusion/hemarthrosis, synovial hypertrophy and cartilage loss. Also, we correlate the ultrasound findings with the corresponding MRI images demonstrating the anatomic planes used for imaging acquisition. Sonography is a promising technique for the assessment of soft tissue changes which are the earliest findings in haemophilic arthropathy. Further investigation is required for evaluation of osteochondral changes given limitations of sonography in this regard and in minimizing operator dependency, especially if applied in multicentric clinical trials.     

Total knee and hip arthroplasty in haemophilic patients

We evaluated the long-term results of three total hip and nine total knee arthroplasties in nine haemophilic patients with disabling pain and end-stage arthropathy. These patients have been followed over a period of 2–12 years (mean 6.9). One patient had a post-operative haematoma, which was evacuated; two patients required manipulation of the knee because of a limited range of motion. There were no infections. At follow-up, all but two patients were completely free of pain; two patients had occasional pain. The functional improvement was impressive with an average increase in the knee score from 37 to 80 points post-operatively. The hip score increased from 36 to 85 points. The range of motion was increased in seven joints, unchanged in two joints and decreased in three. One total hip arthroplasty was revised after 9 years for aseptic loosening. One total knee demonstrated nonprogressive radiographic evidence of aseptic loosening. Median consumption of coagulation factor concentrate in severe haemophiliacs decreased from 47.00 U yr⁻¹ (range 16.000–144.000) before surgery, to 25.000 U yr⁻¹ (range 18.000–132.000) at 2 years after surgery. Conclusion: hip and knee arthroplasty is a valuable option in symptomatic haemophilic patients with disabling arthropathy, in order to obtain pain relief and functional improvement. It is associated with a low rate of complications and may reduce the need for substitution of factor VIII and IX.     

Deep venous thrombosis was not detected after total knee arthroplasty in Japanese patients with haemophilia

Combined thrombo‐prophylaxis with mechanical and pharmacological methods is recommended in patients undergoing total knee or hip arthroplasty. As patients with ‘untreated inherited bleeding disorders such as haemophilia’ are at risk of bleeding, no prophylaxis has been prescribed for these patients. However, a retrospective study reported subclinical deep venous thrombosis (DVT) in 10% of patients with haemophilia undergoing major orthopaedic surgery. In this study, we aimed to evaluate the risk of DVT after total knee arthroplasty (TKA). We examined 38 TKA in 33 Japanese patients with haemophilia using ultrasonography. We did not detect DVT. The risk of DVT in patients with haemophilia after TKA may be lower than that in the general population. However, as patients with haemophilia progress in age, venous thromboembolism should be considered as a potential problem.     

The risk of elective orthopaedic surgery for haemophilia patients: Japanese single‐centre experience

Haemophilic arthropathy causes pain and a severely restricted range of motion, and results in a significant reduction in quality of life. When conservative treatments have failed, orthopaedic surgery is recommended for these patients with severe haemophilic arthropathy. However, surgery for haemophilia patients is challenging due to high complication rate such as infection, delayed wound healing and mortality. The aim of this study was to evaluate the incidence of early complications and identify preoperative risk factors of surgery for haemophilia patients. We report a series of haemophilia patients undergoing elective orthopaedic surgery between 2006 and 2012. During this period, 119 surgeries in 81 patients were prepared and 118 surgeries in 80 patients were actually performed. Four deep bacterial infections and four delayed wound healings occurred within 6 months postoperatively. One patient died preoperatively and four patients died postoperatively. Only the presence of inhibitor was a significant risk factor for infection. We found no risk factor related to delayed wound healing. Our data revealed alkaline phosphatase, albumin, platelet, alpha‐fetoprotein, presence of ascites and child classification C as predictors of perioperative mortality following elective orthopaedic surgery. Our role is to identify potential patients who present with risk factors for complications and attempt to seek the best determination of treatment strategy for these people.     

Management of haemophilic arthropathy

Summary.  Despite the tremendous benefit offered by primary prophylaxis, recurrent joint bleeding with progression to chronic synovitis and haemophilic arthropathy is still a daily concern for the multidisciplinary health care teams managing patients with severe haemophilia or haemophilia complicated by inhibitor development. Advanced stages of arthropathy could be prevented by regular assessment of musculoskeletal status and thus early detection of symptoms, daily rehabilitation exercises at home, and implementation of appropriate physiotherapy and medical training. Patient's education and psychological counselling are crucial. New tools such as magnetic resonance imaging are promising for the monitoring of these patients and might promote early detection of arthropathy and thus appropriate preventive measures to avoid further joint deterioration can be implemented. Medical synovectomy such as radionucleide synoviorthesis is a simple and non-invasive procedure that often delays the need for surgery which despite considerable improvement in techniques and postoperative rehabilitation remains a high-risk strategy in patients with severe haemophilia, especially those with inhibitors. In these high risk patients, availability of specific clotting factors such as activated prothrombin complex concentrate (FEIBA^®, Baxter, Vienna, Austria) and more recently, recombinant factor VIIa (rFVIIa, NovoSeven^®, Bagsvaerd, Denmark) has allowed to perform effective and safe orthopaedic procedures. The on-going EUREKA study will undoubtedly provide additional information about the optimal use of rFVIIa in this context.     

Haemophilia in Poland

The primary aim of this study was to analyse the data on 2269 haemophilic patients in the Polish National Register of Inherited Bleeding Disorders -- 1953 haemophilia A patients and 316 haemophilia B patients. Haemophilia A occurred in 1512 families, haemophilia B in 240 families. In the majority of haemophilia A and B cases severe haemophilia prevailed (59.7% and 56.6% respectively). In about 50% of haemophilic patients, no family history of bleeding diathesis was reported. For haemophilia A patients the mean age was 30.9 years and for haemophilia B patients, 29.2 years. Prevalence of haemophilia in Poland is approximately 1:12 300 inhabitants (1:5600 males). The second aim was to describe the orthopaedic status of severe haemophilia patients and to relate this status to the type of replacement therapy they received prior to the study. Ninety-two severe haemophilia patients (median age 26.0 years) were enrolled in the study. Right and left knee, elbow and ankle joints were evaluated clinically using the Gilbert scale. X-ray examinations were evaluated according to the Pettersson scale. Knee joints proved to be most affected. Eighty-four patients (91.3%) reported pain. Only one scored 0 on the Gilbert scale, another on the Pettersson scale. Thirty-seven per cent of patients used orthopaedic equipment, either occasionally or constantly. Twenty-five per cent had a history of orthopaedic surgery. Thirty-eight per cent were unemployed with some form of social subvention. On-demand treatment was applied. None of the patients received primary prophylaxis. The mean consumption of clotting factor concentrates was 68 054 IU per patient during the 12 months prior to the current study. These results indicate that in Poland all severe haemophilia patients above 20 years are affected by haemophilic arthropathy.     

Knee and hip arthroplasty infection rates in persons with haemophilia: a 27 year single center experience during the HIV epidemic

Total joint replacement (TJR) is an option for the management of chronic haemophilic arthropathy. Because surgery is technically challenging, there is a high rate of deep prosthetic infections, particularly in human immunodeficiency virus (HIV)-infected individuals. We determined the incidence of deep infection rates following total knee and hip arthroplasties in HIV-seropositive and HIV-seronegative persons with haemophilia. Fifty-one primary joint replacements were performed on 32 patients seen at a regional comprehensive haemophilia care center from 1975 to 2002. Thirty prostheses were placed in patients who were HIV-seropositive prior to surgery (n = 14) or seroconverted later (n = 16). Median age at the time of surgery was 33 years (range: 20-61) among 19 HIV-seropositive patients and 35 years (range: 26-74) among 13 HIV-negative patients. Median duration of follow-up was 83 months (range: 2-323). Rate of primary joint infection per artificial joint-year by HIV status was compared by Poisson regression. Main outcome measures were the incidence of primary replacement joint infections by HIV status. Deep infections developed in five (9.8%) of 51 replacement joints. There were two infections during 204.15 joint-years without HIV infection and three infections during 205.28 joint-years with HIV infection. The incidence rate of joint infection (0.98 vs. 1.46 per 100 joint-years) was not increased with HIV (relative risk, RR: 1.49, 95% CI: 0.25-8.93, P = 0.66). We conclude that HIV infection is not a contraindication to knee or hip replacement arthroplasty in the appropriate clinical setting.
