An unusual presentation of mycetoma around knee joint as a subcutaneous mass - A case report.

Introduction: Mycetoma is a form of chronic granulomatous disease which involves subcutaneous tissues and causes bone destruction in advanced stages. The characteristic features are sinus formation, granules formation, and mass in subcutaneous region.

Case Report: A 19-year-old male presented to our out-patient clinic with complaint of a painless swelling around the medial aspect of the right knee joint for 8 months with no sinus or discharge of granules.

Pes Anserinus Bursitis: A Case Report.

Pes anserinus bursitis is a differential diagnosis for knee pain, that may be misdiagnosed. Without proper physical examination and thorough history taking, the diagnosis of pes anserinus may be delayed. We present a case report of this condition, involving both primary care and the emergency department.

Ultrasonography findings in knee osteoarthritis: a prospective observational cross-sectional study of 100 patients.

Worldwide, knee osteoarthritis (KOA) accounts for 2.2% of total years lived with disability. There is a low correlation between joint tissue damage and pain intensity.

Giant pes anserinus bursitis: A rare soft tissue mass of the medial knee.

Bursae are small, jelly-like sacs that are located throughout the body, mainly around the shoulder, elbow, hip, knee, and heel in a number over 150. They contain a small amount of fluid, and are positioned between bones and soft tissues, acting as cushions to help reduce friction. Pes anserinus bursae, despite being clinically frequent, are not visible either by ultrasound (US) or magnetic resonance image (MRI).

Rupture of pes anserine bursa in a patient with pes anserine pain syndrome due to osteoarthritis.

Pes anserinus pain syndrome is a common, clinically defined condition that is characterized by pain around the medial knee and tenderness over the upper medial tibia. The anserine bursa could be the site of proliferative and inflammatory conditions due to knee osteoarthritis, leading to pain and fluid retention. However, rupture of the pes anserinus is rare.

Accuracy and efficacy of ultrasound-guided pes anserinus bursa injection.

Purpose: To compare the accuracy and efficacy of ultrasound (US)-guided versus blind pes anserinus bursa (PAB) injection in patients with pes anserinus tendinobursitis (PATB).

Methods: Forty-seven patients with clinically diagnosed PATB were randomly assigned to a US-guided group or a blind group of steroid injection. In the US-guided group, the injectate was delivered under sonographic visualization.

Pes Anserinus Bursitis due to Tibial Spurs in Children.

Osteochondromas are the most common bone tumours. Although these tumors are relatively common in the long bones of children, the varied clinical and radiographic presentation of such neoplasms around the knee joint can cause diagnostic delays, especially when not associated with a palpable swelling. Proximal tibial osteochondromas can sometimes unusually present as spurs/ rose thorns leading to pes anserinus bursitis and vague knee pain.

Pes Anserinus Syndrome Caused by Osteochondroma in Paediatrics: A Case Series Study.

Introduction: Osteochondroma is a common benign bone tumor, protruding from the underlying normal bone. Osteochondromas can cause pain depending on their location and size. The pes anserinus is located at the proximal medial side of the tibia, where the tendinous insertions of the sartorius, gracilis and semitendinosus muscles collectively attach.

Effects of kinesiotaping versus non-steroidal anti-inflammatory drugs and physical therapy for treatment of pes anserinus tendino-bursitis: A randomized comparative clinical trial.

Objective: Pes anserinus tendino-bursitis is a condition caused by repetitive friction over the bursa or direct trauma to knee joint and it presents with proximal medial tibial pain and swelling. The aim of this study is to determine the effects of kinesiotaping in comparison with naproxen and physical therapy in treatment of pes anserinus tendino-bursitis.

Methods: In a randomized comparative clinical trial 56 patients with clinical diagnosis of pes anserinus tendino-bursitis were randomly assigned to kinesiotaping and naproxen/physical therapy (28 patients in each group).

Ultrasonographic assessment of pes anserinus tendon and pes anserinus tendinitis bursitis syndrome in patients with knee osteoarthritis.

Objective: The aim of this study was to assess the ultrasonographic (US) findings of pes anserinus tendon and bursa in patients with knee osteoarthritis (OA) with or without clinical pes anserinus tendinitis bursitis syndrome (PATBS).

Methods: A total of 157 female patients with the diagnosis of knee OA on both knees (314 knees), and 30 age, and body mass index- matched healthy female controls without knee pain (60 knees), were included in the study. PATBS was clinically diagnosed.

Giant cell tumor of the pes anserine bursa (extra-articular pigmented villonodular bursitis): a case report and review of the literature.

Pigmented villonodular synovitis (PVNS) is a rare, benign, proliferating disease affecting the synovium of joints, bursae, and tendon sheaths. Involvement of bursa (PVNB, pigmented villonodular bursitis) is the least common, and only few cases of exclusively extra-articular PVNB of the pes anserinus bursa have been reported so far. We report a case of extra-articular pes anserine PVNB along with a review of the literature.

Anserine syndrome.

Knee pain is a common complaint in clinical practice, and pes anserinus tendino-bursitis syndrome (PATB) has been frequently diagnosed based only on clinical features that may cause equivocal interpretations. Patients complain of characteristic spontaneous medial knee pain with tenderness in the inferomedial aspect of the joint. Studies with different imaging modalities have been undertaken during the last years to identify whether these patients suffer from bursitis, tendinitis, or both.

[Treatment of Pes anserinus bursitis with debridement under arthroscopy].

Objective: To explore the clinical effectiveness of debridement in treatment of Pes anserinus bursitis under arthroscopy by comparing the curative effect of three therapies: local block therapy, open operation and debridement under arthroscopy.

Methods: From January 2000 to January 2007, 90 cases of unilateral Pes anserinus bursitis were treated with debridement under arthroscopy (group A, n=30), local block therapy (group B, n=30) and open operation (group C, n=30), respectively. The group A included 18 males and 12 females, aged (40.

Overload syndromes of the knee in adolescents: Sonographic findings.

Overload syndromes are caused by repetitive microtrauma, and the knee joint is most frequently affected in adolescents. The reason for this is that the knee joint is engaged in almost all sports activities. Pathologies related to the anterior aspect of the knee are: femoropatellar pain, jumper's knee syndromes, Osgood-Schlatter disease, Sinding-Larsen-Johansson syndrome and patellar stress fractures; to the medial aspect: semimembranous tendon enthesopathy and pes anserinus bursitis; to the lateral aspect: iliotibial band syndrome (runner's knee), popliteus and femoral biceps tendon enthesopathy; to the posterior aspect: fabella syndrome and medial gastrocnemius muscle tendon enthesopathy.

Pigmented villonodular bursitis/diffuse giant cell tumor of the pes anserine bursa: a report of two cases and review of literature.

Pigmented villonodular synovitis (PVNS) is a benign but potentially aggressive lesion, characterized by synovial villonodular proliferation with hemosiderin pigmentation and stromal infiltration of histiocytes and giant cells. This consists of a common family of lesions, including localized and diffuse forms of pigmented villonodular synovitis, giant cell tumor of the tendon sheath (nodular tenosynovitis) and the very rare cases of extra-articular pigmented villonodular synovitis arising from the bursa (pigmented villonodular bursitis or diffuse giant cell tumor of the tendon sheath). The purpose of this paper is to present two rare cases of pigmented villonodular bursitis arising from the pes anserinus bursa.

Knee pain in saphenous nerve schwannoma: case report.

The differential diagnosis of anteromedial knee pain is extensive and can be associated with meniscal tear, medial collateral ligament sprain, or pes anserinus bursitis. An association between knee pain and a peripheral nerve sheath tumor has rarely been reported. The authors describe the case of a 44-year-old man with a saphenous nerve schwannoma who presented with vague pain in the medial aspect of his knee mimicking the clinical presentation of a meniscal tear.

Risk factors for pes anserinus tendinitis/bursitis syndrome: a case control study.

Background: Pes anserinus tendinitis/bursitis (PATB) is a frequent cause of knee pain. Its predisposing factors are still controversial.

Objectives: Assess the effect of a set of demographic, clinical, somatometric, and biomechanical factors on the risk for PATB.

Correlation between ultrasonographic findings and the response to corticosteroid injection in pes anserinus tendinobursitis syndrome in knee osteoarthritis patients.

The objectives of this study were to assess the ultrasonographic (US) findings in patients with knee osteoarthritis (OA) with pes anserinus tendinitis or bursitis (PATB) syndrome and to determine the correlation between the US findings and the response to local corticosteroid injection. We prospectively studied 26 patients with knee OA with clinically diagnosed PATB syndrome. A linear array 7 MHz transducer was used for US examination of the knee.

Polyethylene-induced pes anserinus bursitis mimicking an infected total knee arthroplasty: a case report and review of the literature.

Polyethylene-induced pes anserinus bursitis after total knee arthroplasty (TKA) with the clinical manifestations mimicking an infected TKA is a very rare occurrence. We report such a case in a 74-year-old woman. She developed recurrent draining papules on the anterolateral aspect of the knee because of polyethylene-induced chronic pes anserinus bursitis 8 years after TKA.

Ultrasonographic evaluation of pes anserinus tendino-bursitis in patients with type 2 diabetes mellitus.

Objective: To assess musculoskeletal ultrasonographic (US) findings in patients with type 2 diabetes mellitus (DM) with and without pes anserinus (PA) tendinitis or bursitis syndrome; and to determine possible etiologic factors such as systemic diabetic microvascular disease complications in these patients.

Methods: The knee joints were examined with an ultrasound real-time scanner using a 10 MHz electronic linear transducer in 48 patients with type 2 DM and 25 controls. The presence of systemic diabetic microvascular disease complications was evaluated.
