Ninety-six percent of minimally invasive knee replacement patients leave same day, no complication

20.12.2005


’Pre-surgical’ team approach gets patients ready to leave same day



Orthopedic surgeons at Rush University Medical Center found that 96 percent of patients who had minimally invasive total knee replacement surgery were able to go home the same day, without complications-many walking out unassisted or with a cane. These results were published in the October issue of the Journal of Arthroplasty.

Lead author surgeon Richard A. Berger says it’s not just the surgeon’s skills and techniques that help patients avoid a hospital stay.


"It’s a comprehensive management pathway helps the patient avoid an overnight stay. It’s optimal sequencing and timing of interventions by the nursing, physical therapy, anesthesia surgical team; it’s a team approach of equally weighted preoperative, intraoperative, and postoperative care."

Patients meet with the physical therapist and nurse prior to surgery. "The nurse time is invaluable to patient before going into surgery," says Berger. "They attend a class led by with a nurse where potential surgical complications and postoperative care are discussed.

Patients spend an hour learning about the surgery, asking questions about pain, recovery and surgery. We reassure patients that their pain will be controlled, that they will be carefully monitored for the occurrence of complications or delayed recovery due to early discharge, and explain how will be able to move around independently after surgery.

After class with the nurse, patients have a physical therapy session for instruction in gait training with crutches and a cane. An internist also evaluates patients as part of our hospital’s policy. Lastly, the hospital discharge planner calls the patient at home before surgery to make sure all someone can take him or her home after surgery."

The 50 study patients (20 female, 30 males) had surgery between August 2003 and August 2004. The average age was 68 years old, average weight of 203 lbs. with a body mass index of 29.2. Forty-eight of the patients had osteoarthritis. Each patient was the first surgical case of the day.

Berger, who pioneered and perfected minimally invasive outpatient surgery, explains his technique for total knee arthroscopy (TKA) does not cut the quadriceps muscle and quadriceps tendon.

"The only incision is from the joint line to the superior pole of the patella. The quadriceps tendon is not cut or split. The knee is not dislocated; instead, in situ cuts are made. The patient is out of surgery in less than two hours."

After surgery, patients see an occupational and physical therapist. To be released, patients must be able to independently get in and out of bed, rise from a chair, walk 100 feet, and walk up and down a full flight of stairs. Patients are then asked if they feel comfortable and would like to go home and are released with pain medication.

Patients receive home physical therapy until they can drive; then, outpatient physical therapy is started. Patients were evaluated clinically and radiographically in the office at one week, two weeks, six weeks, and three months.

Berger says this study demonstrates that, in these selected patients, "outpatient TKA was safe with no short-term readmission or complications related to early discharge. New clinical pathways, including improvements in anesthetic techniques, postoperative pain management, and rehabilitation protocols, will make performing outpatient TKA a realistic goal. This comprehensive pathway may make it possible for this minimally invasive knee surgery to be done as an outpatient in specialized surgicenters in the future."

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
