Vascular malformations in muscles around the knee presenting as knee pain.

Vascular malformations involving the muscles around the knee can be a cause of knee pain. We studied ten such cases. All underwent magnetic resonance (MR) imaging which confirmed the diagnosis. Eight cases underwent wide surgical excision of the lesion, histology of which showed a vascular malformation with predominantly venous element. There was no recurrence in any of the operated cases at the last follow-up. We believe that most of these lesions can be treated successfully by careful preoperative planning aided by MR imaging and a wide-open excision of the lesion.

The 'Delhi active test' for detection of anterior cruciate ligament tears.

All the described tests for the detection of anterior cruciate ligament (ACL) tear are passive tests. For obese or muscular built patients these tests are cumbersome and often unsuitable. We describe for the first time a new method, the 'Delhi active test', by which a torn ACL can be detected irrespective of the size or build of the patient. The results of this test are reproducible and the diagnostic accuracy is comparable with other tests. We suggest that the 'Delhi active test' be used as one of the routine clinical methods to detect the torn ACL.

Assessment of blood-induced cartilage damage in rabbit knees using scanning electron microscopy.

PURPOSE: To investigate the harmful effects of a single episode of intra-articular bleeding on articular cartilage of rabbit knees using scanning electron microscopy. METHODS: Autologous blood was injected into the right knee joints of 18 New Zealand white rabbits. Surface and cellular damages were examined by the scanning electron microscope (n=9) and light microscope (n=34), respectively. The injected right knees were then compared with the corresponding control left knees at one, 3, and 6 weeks after the blood injection. RESULTS: The articular surface of the injected knees turned uniformly rough with multiple pits after one week. Maximal changes with elevations and depressions were observed at 3 weeks. These changes reversed at 6 weeks with the irregularities smoothing out. A similar pattern of transient cartilage damage was noted histologically. CONCLUSION: Both scanning electron microscopic and light microscopic findings suggest that a single episode of intra-articular bleeding leads to articular cartilage damage but this appears to be reversible. Our findings of transient damage to the articular cartilage suggest that there is no need for intra-articular evacuation and washout following an acute episode of haemarthrosis.

Radiotherapy for desmoplastic fibroma of bone: a case report.

Desmoplastic fibroma is a rare benign tumour of bone. Diagnosis is not easy and is often made by excluding other tumours. Histopathological diagnosis of this tumour is also sometimes not easy. The treatment modalities for this tumour are non-uniform and often controversial. In the present case surgical options were left aside because the patient did not consent to surgery, so radiotherapy was used, with success at 3-year follow-up. This case is presented here along with a review of relevant literature.

Blount's disease: a lesser known cause of bowlegs mandating early differentiation from physiological bowing.

We present a 16-month-old child, with progressively increasing bowing of legs, having a normal serum calcium, phosphorus and alkaline phosphatase level; lower limb radiographs revealed bilateral medial tibial metaphyseal beaking. Based on these findings, a diagnosis of Blount's disease (infantile tibia vara) was made and an orthotic management program was instituted for the child.
