A jumper's knee is an overload lesion of patellar or quadriceps tendon near its insertion at the lower or upper pole of the patella. If conservative treatment fails, an operation can be performed in Phase 3 where disabling symptoms, are present. The necrotic tissue in the patellar tendon is excised. The early results of this surgery are encouraging.

Intracranial hypertension and acute renal failure are frequent complications in polytraumatized patients with head trauma. This paper deals with the evolution of intracranial pressure during haemodialysis in two cases of traumatic coma. Significant changes in intracranial pressure were noted. Increase of intracranial pressure during haemodialysis was 7.6 mmHg for the first patient and 4.6 mmHg for the second patient. Prophylactic measures are discussed.
