The Knee Exam
Observation:
1. Make sure that both knees are fully exposed. The patient should be in either a gown or shorts. Rolled up pant legs do not provide good exposure!
2. Watch the patient walk. Do they limp or appear to be in pain? When standing, is there evidence of bowing (varus) or knock-kneed (valgus) deformity? There is a predilection for degenerative joint disease to affect the medical aspect of the knee, a common cause of bowing. Varus Knee Deformity, more marked on the left leg. 3. Make note of any scars or asymmetry. Chronic/progressive damage, as in degenerative joint disease, may lead to abnormal contours and appearance. Is there obvious swelling as would occur in an effusion? Redness suggesting inflammation? 4. Is there evidence of atrophy of the quadriceps, hamstring, or calf muscle groups? Knee problems/pain can limit the use of the affected leg, leading to wasting of the muscles.
While both legs have well developed musculature,
the left calf and hamstring are bulkier than the right. 5. Look at the external anatomy, noting structures above and below the knee itself: 1. Patella 2. Patellar tendon 3. Quadriceps/Hamstring/Calf muscles 4. Medial and lateral joint lines. 5. Femur and Tibia 6. Tibial tuberosity
Ballotment (helpful if the effusion is large) 1. Slightly flex the knee which is to be examined.
2. Place one hand on the supra-pateallar pouch, which is above the patella and communicates with the joint space. Gently push down and towards the patella, forcing any fluid to accumulate in the central part of the joint.
3. Gently push down on the patella with your thumb.
4. If there is a sizable effusion, the patella will feel as if it's floating and "bounce" back up when pushed down.
On Tuesday May 29th at 3:00pm EDT, University Hospitals Case Medical Center Cleveland, Ohio, will host a live webcast to demonstrate the removal of brain tumor and epileptic focus from an awake patient using intra-operative MRI and brain mapping. See this on OR-Live.com
The patient was a middle-aged gentleman with new onset seizures. An MRI showed what appeared to be a low grade glioma near the motor strip on the right. Studies have shown that complete removal can cure the seizures, improve quality of life and survival, but this is difficult to do with conventional technology without harming the surrounding normal brain because its difficult to determine where tumor ends and normal brain begins.
Various laparoscopic techniques have been described for the insertion of peritoneal dialysis catheters. However, most use 3 to 4 ports, thus multiplying the potential risk for abdominal wall complications (hemorrhage, hernia, leaking). With the technique presented herein a Tenckhoff catheter is plac...ed laparoscopically, using just 1 port, in 13 consecutive patients with end-stage renal failure. The catheter is fixed in the abdominal cavity with no additional ports for this purpose. The simplicity and the rapidity of the method justifies serious consideration for its use as the standard Tenckhoff catheter placement.

common knowledge. Mitral and tricuspid valve replacement results are on the whole far worse than for example Aortic valve. Mitral valve replacement should be the last resort and patients with very severe valvular and sub valvular mitral disease can nowadays be helped by mitral valve repair. NO MITRAL OR TRICUSPID VALVE SHOULD BE REPLACED IF IT CAN BE REPAIRED

This shows a full Abdominoplasty surgery performed by Dr. Art Foley in Olympia Washington. Abdominoplasty is also commonly referred to as a "Tummy Tuck." Tummy tuck is a surgical procedure also known as abdominoplasty to remove excess skin and fat from the middle and lower abdomen and to tighten the muscles of the abdominal wall. The procedure can dramatically reduce the appearance of a protruding abdomen. But bear in mind, it does produce a permanent scar.
