Synoviale Erkrankungen und freie Körper des Hüftgelenks

Synovial disorders and loose bodies are one of the most common indications for hip arthroscopy. Arthroscopic intervention has been reported for loose bodies, synovial plicae, synovial chondromatosis, pigmented villonodular synovitis (PVNS) as well as rheumatoid and septic arthritis. One major advantage in comparison to radiologic imaging is the ability to inspect, biopsy, and treat within one procedure. In contrast to an arthrotomy, hip arthroscopy avoids the potential risks of extensive surgical exposure and prolonged rehabilitation. Nevertheless, hip arthroscopy cannot be promoted as curative in all synovial disorders. In patients with loose bodies, synovial plicae, initial septic arthritis and, to a certain extent, PVNS curative therapy and "restitutio ad integrum" can be achieved. In contrast, in patients with synovial chondromatosis and rheumatoid arthritis, the goal of hip arthroscopy is to enable the correct diagnosis and to provide symptomatic relief and maintain or improve joint function. Success or failure of arthroscopic treatment depends on proper patient selection and a correct arthroscopic technique.     

Arthroscopy in primary synovial chondromatosis of the hip: description and outcome of treatment

Between 1985 and 2000, 120 patients underwent arthroscopic management for primary synovial chondromatosis of the hip. We report the outcome of 111 patients with a mean follow-up of 78.6 months (12 to 196). More than one arthroscopy was required in 23 patients (20.7%), and 42 patients (37.8%) went on to require open surgery. Outcomes were evaluated in greater detail in 69 patients (62.2%) treated with arthroscopy alone, of whom 51 (45.9%) required no further treatment and 18 (16.2%) required further arthroscopies. Of the 111 patients, 63 (56.7%) had excellent or good outcomes. At the most recent follow-up, 22 patients (19.8%) had undergone total hip replacement. Hip arthroscopy proved beneficial for patients diagnosed with primary synovial chondromatosis of the hip, providing good or excellent outcomes in more than half the cases.

Arthroscopy of the hip--surgical treatment of synovial osteochondromatosis

The hip arthroscopy is an efficient procedure in treatment of synovial chondromatosis in selected patients. The advantages compared to open procedures are lesser operative moribidity and faster postoperative recovery.     

Arthroskopische Synovektomie des Hüftgelenks

Objective

The aim of the treatment is reduction of hip pain through arthroscopic synovectomy of the hip joint, reduction in activity of the synovial disease and removal of loose bodies in chondromatosis.

Indications

Synovialitis of the hip due to synovial disease, such as pigmented villonodular synovitis (PVNS) and chondromatosis, synovialitis of the hip due to a further diseases of the hip. The disease must be treatable by arthroscopy (e.g. femoroacetabular impingement and lesion of the acetabular labrum).

Contraindications

Suspicion of malignant synovial disease, extensive synovitis, especially in those areas of the hip which are difficult to reach or inaccessible to arthroscopy, primary disease not sufficiently treatable by arthroscopy, e.g. coxarthrosis.

Surgical technique

Arthroscopy of the central compartment of the hip is carried out by lateral, anterolateral (alternatively inferior anterolateral) and posterolateral portals, using all portals both for the camera and for instruments. In the central compartment synovectomy of the acetabular fossa is performed. A shaver and/or a high frequency diathermy applicator (HF applicator) are employed for removal of the synovial membrane. For arthroscopy of the peripheral compartment lateral, anterolateral (alternatively inferior anterolateral) and superior anterolateral portals are established and all portals are used both for the camera and instruments. In the peripheral compartment, the synovial membrane of the anterior, anteromedial, anterolateral and as far as possible posterolateral areas of the hip is removed. The dorsolateral synovial plica needs to be spared.

Postoperative management

Non-steroidal anti-inflammatory drugs (NSAIDs) are administered as prophylaxis of heterotopic ossification for 10 days. Contraindications for NSAIDs need to be considered. Thrombosis prophylaxis with low molecular weight heparin over 5 days. Mobilization with full weight bearing. Intensive physiotherapeutic exercises for at least 6 and possibly up to 12 postoperative weeks. Radiosynoviorthesis 6–8 weeks after surgery depending of the histopathological results.

Results

From June 2007 to December 2013 a total of 20 patients with specific synovial diseases were treated with hip arthroscopy of which 18 had chondromatosis and 2 had PVNS. A telephone interview was carried out after an average of 40.2 months (range 8–92 months) and revealed a recurrence rate of the synovial disease of 20?%. In two cases (10?%) a second arthroscopy was necessary due to recurrent symptoms but without return of the synovial disease.

Arthroscopic Retrieval of over 100 Loose Bodies in Shoulder Synovial Chondromatosis: A Case Report and Review of Literature

Synovial chondromatosis is a rare and benign condition of unknown cause. It is also known as synovial osteochondromatosis. It is characterized by involvement of the synovial tissue, which lines various joints of our body. Initial symptoms range from pain in the joint, locking of the joint at times, especially the knee, to arthritis of the joint that is a late feature of this condition. Although large joints such as the knee are commonly affected, involvement of the shoulder joint is a rare occurrence. Historically an open arthrotomy was preferred for removal of loose bodies coupled with a thorough synovectomy. However, arthroscopy for loose body retrieval has gained popularity over the past two decades. Arthroscopic surgery is an extremely skilled procedure and there is a learning curve for operating in certain anatomical areas such as the shoulder. However, not only does an arthroscopy provide the surgeon with an excellent view of the shoulder but the patient also has a faster recovery. We report a rare case of shoulder synovial chondromatosis in which more than 100 loose bodies were successfully retrieved by an arthroscopy in an individual who had an excellent outcome post‐surgery, reaffirming our faith in the procedure. A detailed literature review of arthroscopic procedures is also presented.     

Synovial Chondromatosis of the Shoulder

Articular synovial chondromatosis is a rare disease commonly affecting the knee, hip or elbow, and characterised by the formation of metaplastic cartilaginous foci in the synovium. A case of synovial chondromatosis affecting the shoulder joint is now reported because of the extreme rarity of the disease in this situation.

Hip Arthroscopy Update

The management of hip injuries in the athlete has evolved significantly in the past few years with theadvancement of arthroscopic techniques. The application of minimally invasive surgical techniques has facilitated relatively rapid returns to sporting activity in recreational and elite athletes alike. Recent advancements in both hip arthroscopy and magnetic resonance imaging have elucidated several sources of intraarticular pathology that result in chronic and disabling hip symptoms. Many of these conditions were previously unrecognized and thus, left untreated. Current indications for hip arthroscopy include management of labral tears, osteoplasty for femoroacetabular impingement, thermal capsulorrhaphy and capsular plication for subtle rotational instability and capsular laxity, lateral impact injury and chondral lesions, osteochondritis dissecans, ligamentum teres injuries, internal and external snapping hip, removal of loose bodies, synovial biopsy, subtotal synovectomy, synovial chondromatosis, infection, and certain cases of mild to moderate osteoarthritis with associated mechanical symptoms. In addition, patients with long-standing, unresolved hip joint pain and positive physical findings may benefit from arthroscopic evaluation. Patients with reproducible symptoms and physical findings that reveal limited functioning, and who have failed an adequate trial of conservative treatment will have the greatest likelihood of success after surgical intervention. Strict attention to thorough diagnostic examination, detailed imaging, and adherence to safe and reproducible surgical techniques, as described in this review, are essential for the success of this procedure.     

Synovial chondromatosis of the shoulder.

Articular synovial chondromatosis is a rare disease commonly affecting the knee, hip or elbow, and characterized by the formation of metaplastic cartilaginous foci in the synovium. A case of cynovial chondromatosis affecting the shoulder joint is now reported because of the extreme rarity of the disease in this situation.     

Results of total hip and total knee arthroplasties in patients with synovial chondromatosis

This retrospective analysis examines the outcome of total joint arthroplasty for severe arthritis in patients with synovial chondromatosis. All 11 patients treated with total hip arthroplasty (n = 7) or total knee arthroplasty (n = 4) returned for follow-up at a mean of 10.8 years after surgery. Pain and functional scores improved significantly in all patients. Knee range of motion improved in all patients. Synovial chondromatosis recurred in 1 knee (25%) and 1 hip (14%). Total joint arthroplasty is a valuable treatment option for these patients with predictable improvement in pain and function. Knee range of motion is likely to improve but may be less than expected for primary total knee arthroplasty. Patients remain at risk for recurrence.     

Arthroscopic treatment of synovial chondromatosis of the knee

Between 1971 and 1987, arthroscopy was performed in 39 patients with synovial chondromatosis of the knee; 29 of these patients (32 knees) were followed an average of 3.5 years. A good result was obtained in 78% of the cases. Removal of loose bodies was the only treatment in 31 of the 32 knees. A synovectomy was performed in one case. No synovectomies were performed secondarily. Only three patients required a second arthroscopic procedure. The essential prognostic factor for a good functional result is the condition of the femorotibial cartilage. We concluded that simple arthroscopic removal of cartilaginous bodies without synovectomy is the treatment of choice for synovial chondromatosis of the knee.     

Arthroscopic intervention in early hip disease

Advancement in diagnostic and therapeutic applications for hip arthroscopy have dispelled previous myths about early hip disease. Arthroscopic findings have established the following facts: Acetabular labral tears do occur; acetabular chondral lesions do exist; tears are most frequently anterior and often associated with sudden twisting or pivoting motions; and labral tears often occur in association with articular cartilage lesions of the adjacent acetabulum or femoral head, and if present for years, contribute to the progression of delamination process of the chondral cartilage. Magnetic resonance arthrography represents an improvement over conventional magnetic resonance imaging, it does have limitations when compared with direct observation. Although indications for hip arthroscopy are constantly expanding, the most common indications include: labral tears, loose bodies, chondral flap lesions of the acetabular or femoral head, synovial chondromatosis, foreign body removal, and crystalline hip arthropathy (gout, pseudogout, and others). Contraindications include conditions that limit the potential for hip distraction such as joint ankylosis, dense heterotopic bone formation, considerable protrusio, or morbid obesity. Complication rates have been reported between 0.5 and 5%, most often related to distraction and include sciatic or femoral nerve palsy, avascular necrosis, and compartment syndrome. Transient peroneal or pudendal nerve effects and chondral scuffing have been associated with difficult or prolonged distraction. Meticulous consideration to patient positioning, distraction time and portal placement are essential. Judicious patient selection and diagnostic expertise are critical to successful outcomes. Candidates for hip arthroscopy should include only those patients with mechanical symptoms (catching, locking, or buckling) that have failed to respond to conservative therapy. The extent of articular cartilage involvement has the most direct relationship to surgical outcomes. Improvements in technique and instrumentation have made hip arthroscopy an efficacious way to diagnose and treat a variety of intra-articular problems.     

Kiefergelenkerkrankungen

In practice, functional disorders of the temporomandibular joint and the surrounding muscles are much more frequent than true diseases of this joint. The two can usually be distinguished from one another by their typical history, signs and symptoms. In patients with disc displacement, disc perforation or osteoarthrosis, surgery is only an option if a set of distinct symptoms are present that do not respond to non-surgical treatment. Surgery may vary from arthroscopy to open surgery in a stepwise algorithm. However, in patients with synovial chondromatosis, developmental diseases, condylar hyperplasia, arthritis, ankylosis and tumors of this joint, surgery should be the first form of treatment considered.
