Patellar-tendon transfer by the slot-block method for recurrent subluxation and dislocation of the patella.
In sixty-five knees followed for an average of 4.5 years after treatment of subluxation or dislocation of the patella by the slot-block method of medial patellar-tendon transfer, the results were satisfactory in fifty-four (83%) and unsatisfactory in eleven (17%). Recurrent subluxation or dislocation occurred in three (5%) of the knees and was attributed to insufficient displacement. ⋯ Two knees (3%) required patellectomy because of patellofemoral symptoms and there were nineteen complications in seventeen knees, including loss of motion in six, wound infection in six, displacement of the bone block in three, recurrent dislocation in three, and rupture of the patellar ligament in one. The method is believed to give superior results but it is technically demanding.

Maintenance of aseptic barriers in the conventional operating room: general principles.
Contamination of operative wounds during surgery occurs primarily through contact and secondarily through the airborne route. Inspection and maintenance of air-handling equipment is essential, with special reference to air intakes, filters, humidifiers, and exhaust systems. ⋯ Intensive interim cleaning of all horizontal sufaces between operations is essential. The infection rate is proportional to the duration of the operation and the number of personnel in the room, and inversely proportional to the air changes per hour.
