1/13. Uncommon causes of anterior knee pain: a case report of infrapatellar contracture syndrome.The uncommon causes of anterior knee pain should always be considered in the differential diagnosis of a painful knee when treatment of common origins become ineffective. A case is presented in which the revised diagnosis of infrapatellar contracture syndrome was made after noting delayed progress in the rehabilitation of an active female patient with a presumed anterior horn medial meniscus tear and a contracted patellar tendon. The patient improved after the treatment program was augmented with closed manipulation under arthroscopy and infrapatellar injection of both corticosteroids and a local anesthetic. Infrapatellar contraction syndrome and other uncommon sources of anterior knee pain, including arthrofibrosis, Hoffa's syndrome, tibial collateral ligament bursitis, saphenous nerve palsy, isolated ganglions of the anterior cruciate ligament, slipped capital femoral epiphysis, and knee tumors, are subsequently discussed. Delayed functional advancement in a rehabilitation program requires full reassessment of the patient's diagnosis and treatment plan. Alternative diagnoses of knee pain are not always of common origins. Ample knowledge of uncommon causes of anterior knee pain is necessary to form a full differential diagnosis in patients with challenging presentations.- - - - - - - - - - ranking = 1keywords = ganglion (Clic here for more details about this article) |
2/13. The quadriceps tendon cyst: an uncommon cause of chronic anterior knee pain.The causes of knee pain are manifold. One of the uncommon causes of chronic anterior knee pain are cysts and ganglia. magnetic resonance imaging not only reveals the intra-articular pathology but also accurately depicts such cystic structures about the knee. As part of this case report, a cyst of the lateral border of the quadriceps tendon is presented as a cause of such discomfort. Although cystic lesions around the knee are a common clinical problem, the described location is rare. After surgical revision of the lateral border of the quadriceps tendon and excision of the cyst, the patient was found to be asymptomatic.- - - - - - - - - - ranking = 1.5732898959492keywords = cyst (Clic here for more details about this article) |
3/13. Intraarticular knee ganglion: a case report of an unusual cause of limping in a 4-year-old.This report describes a 4-year-old boy who presented to the orthopaedic clinic with a primary complaint of limping and refusal to bear full weight on his right leg. An extensive evaluation revealed an intercruciate ganglion cyst of the knee. Diagnostic arthroscopy of the right knee was performed, and the cyst was aspirated and debrided. magnetic resonance imaging of the knee 3 months and 1 year postoperatively showed a small remnant of the cyst adjacent to the posterior cruciate ligament. At the most recent clinical examination, 13 months postoperatively, the patient was symptom free. To the best of our knowledge, this is the youngest patient in the literature to be diagnosed with an intraarticular knee ganglion.- - - - - - - - - - ranking = 104.95573926175keywords = ganglion cyst, ganglion, cyst (Clic here for more details about this article) |
4/13. giardiasis-associated arthralgia in children.BACKGROUND: giardiasis is the most common intestinal parasitosis in mexico. Usual symptoms of the acute infection are diarrhea, abdominal pain, nausea, and weight loss. Children are more frequently affected than adults. Various extra-intestinal manifestations have been reported, among which are arthritis and arthralgia. methods: A series of 10 children with arthralgia and cysts of giardia lamblia in feces seen during 13 years of private practice were presented. Ages ranged between 5 and 11 years, and 70% of the children are males. RESULTS: The joints involved in all cases were the knee and the ankle. No joint flogosis or changes in local temperature were observed. Other associated symptoms were abdominal pain (100%), abdominal distension (70%), flatulence (50%), less consistent stools (50%), anemia (30%), and increased erythrocyte sedimentation rate (60%). c-reactive protein and rheumatoid factor were negative in all cases. arthralgia disappeared after treatment with metronidazole when coproparasitoscopic analyses were negative. CONCLUSIONS: arthralgia associated with giardiasis in children is a rare entity, relatively benign, and leaves no sequelae.- - - - - - - - - - ranking = 0.1748099884388keywords = cyst (Clic here for more details about this article) |
5/13. Postmeniscectomy osteonecrosis.In the last few years, postmeniscectomy osteonecrosis has been reported, especially in elderly patients, with low incidence, unclear physiopathology, and without long periods of follow-up. We report a case diagnosed and followed-up for a 3-year period using magnetic resonance imaging. In the initial phase, a large area of intramedullary edema was evident; after 3 months, the edema had decreased (it was no longer evident at 1 year examination) and a clearly defined area of osteonecrosis was evident with very high signal intensity on high-contrast sequences. After 3 years, the lesion showed a degenerative cyst appearance with an osteosclerotic rim and completely disrupted cartilage.- - - - - - - - - - ranking = 0.1748099884388keywords = cyst (Clic here for more details about this article) |
6/13. A case of intra-articular snapping hip caused by articular cartilage detachment from the deformed femoral head consequent to Perthes disease.We treated a relatively rare case of intra-articular snapping hip caused by an articular cartilage fragment detached from the deformed femoral head consequent to Perthes disease. We report the pathology as well as diagnosis and treatment of this case. A 24-year-old man presented with right coxalgia. He was diagnosed with Perthes disease at a young age and was treated conservatively. Six months before the patient visited our department, he started having intense pain accompanied by a clicking sound when he extended and at the same time externally rotated the right hip joint from a flexed position. Although a radiogram showed Stulberg class 3 deformity of the femoral head, the joint space was well preserved and no bone cyst or bone spur formation was seen. Computed tomography (CT) and magnetic resonance imaging (MRI) showed no abnormal findings inside the femoral head and in the hip joint. However, when 5 mL of 2% lidocaine hydrochloride was injected into the hip joint, the snapping phenomenon persisted but the sharp pain was temporarily resolved. Arthroscopic finding showed a valve-shaped detachment of articular cartilage in the anteromedial side of the femoral head. Arthroscopic shaving of the detached fragment was conducted. The pain and clicking sound accompanying hip joint movement disappeared postoperatively. hip joint arthroscopy is useful for the diagnosis and treatment of intra-articular type snapping hip when the cause of snapping is inside the joint cavity.- - - - - - - - - - ranking = 0.1748099884388keywords = cyst (Clic here for more details about this article) |
7/13. Dorsal wrist syndrome repair.Dorsal wrist pain with or without a palpable dorsal wrist ganglion is a common complaint. Watson developed the concept of the dorsal wrist syndrome (DWS) which is an entity encompassing pre-dynamic rotary subluxation of the scaphoid and the overloaded wrist. We reviewed 20 cases of DWS treated surgically. There were nine males (11 wrists) and nine females (nine wrists). Post-operative follow-up ranged from five to 67 months (mean, 37 months). At operation, we observed SLL tears in eight wrists and dorsal ganglia in 12 cases. Following surgery, 12 cases reported being pain free, five had mild pain, two moderate pain and one case reported severe pain. Post-operative extension/flexion was 73/70 average. Post-operative grip strength was 28 kg average. We believe that excision of the posterior interosseous nerve and the dorsal capsule including the ganglion, if present, provides pain relief in DWS.- - - - - - - - - - ranking = 2keywords = ganglion (Clic here for more details about this article) |
8/13. Mucoid degeneration of the anterior cruciate ligament--a report of two cases.We report two cases of mucoid degeneration of the anterior cruciate ligament (ACL). Mucoid degeneration of the ACL is a very rare cause of knee pain. There have been only seven reported cases of mucoid degeneration of the ACL in the English literature. We reviewed previous reports and summarized clinical features and symptoms, including those found in our two cases. MRI is the most useful tool for differentiating mucoid degeneration of the ACL from an intraligamentous ganglion or other lesions in the knee joint. If this disease is considered preoperatively, it can be diagnosed easily based on characteristic findings.- - - - - - - - - - ranking = 1keywords = ganglion (Clic here for more details about this article) |
9/13. Ganglion cyst of the anterior cruciate ligament: a case report.A ganglion is a cystic swelling that usually arises close to tendons or joints. Its occurrence inside a joint is rare, and its diagnosis is usually incidental during magnetic resonance imaging or arthroscopy. It may be painful or asymptomatic. Some patients may have a trauma history. ganglia may mimic intra-articular lesions like tears of the anterior cruciate ligament or meniscus. magnetic resonance imaging is the investigation of choice for diagnosis. ganglia commonly arise from the anterior cruciate ligament, but can also arise from other structures such as the posterior cruciate ligament or meniscus. ganglia are typically treated by arthroscopic excision and debridement. We report a case of ganglion cyst of the anterior cruciate ligament in a 16-year-old man.- - - - - - - - - - ranking = 101.48016922707keywords = ganglion cyst, ganglion, cyst (Clic here for more details about this article) |
10/13. Glenoid-labral cyst entrapping the suprascapular nerve: dissolution after arthroscopic debridement of an extended SLAP lesion.Glenoid labral cysts are commonly associated with labral tears, which can cause pain or instability. We present the case of a patient, referred for neurological complaints, who was actually suffering from supraspinatus nerve entrapment syndrome. Electroneurogram studies showed an isolated lesion of the branch to the infraspinatus muscle. magnetic resonance imaging confirmed a glenoid labral cyst extending from the cranial glenoid to the scapular notch. After arthroscopic debridement of an extended SLAP-lesion that had caused joint fluid extrusion, the dissolution of the cyst was associated with complete neurological recovery. The patient is pain free and range of motion is normal. An attempt at an arthroscopic procedure seems warranted in cases like this, since cysts that accompany labral tears can dissolve after rigorous debridement of the torn labrum, much like meniscal cysts. Extended and hazardous open excisions can thus be avoided.- - - - - - - - - - ranking = 1.5732898959492keywords = cyst (Clic here for more details about this article) |
