What does JOHN HERMANSDORFER research?

Dr. Hermansdorfer studies injuries, particularly those common in athletes, and how they can be treated without surgery. One key area of his research involves the medial collateral ligament (MCL) injuries in football players, aiming to find effective rehabilitation techniques. Additionally, he explores the antibiotic resistance of bacteria found in medicinal leeches, aiming to ensure patients receive the right treatment to prevent infections, especially after surgeries that involve these leeches.

Key findings

  • In a study of 28 college football players with complete MCL tears, 20 out of 21 players achieved good to excellent recovery results after non-surgical treatment, allowing most to return to full contact practice in about 9 weeks.
  • The research on Aeromonas hydrophila highlighted that this bacteria was resistant to penicillin and some earlier antibiotics, but responded well to gentamicin, tetracycline, and modern antibiotics like cefamandol and cefoxitin.
  • Dr. Hermansdorfer's findings suggest that nonoperative management can effectively treat MCL injuries, helping athletes avoid surgery and recover efficiently.

Frequently asked questions

Does Dr. Hermansdorfer study knee injuries?
Yes, he focuses on nonoperative treatments for knee injuries, particularly complete tears of the medial collateral ligament.
What treatments has Dr. Hermansdorfer researched?
He has researched physical therapy and rehabilitation techniques for sports injuries, specifically for knee ligament injuries.
Is Dr. Hermansdorfer's work relevant to patients using medicinal leeches?
Yes, he studies antibiotic effectiveness related to the bacteria found in medicinal leeches, which is important for preventing infections during leech-related surgeries.
What are the outcomes of non-surgical treatment for MCL tears?
His research shows that many athletes can have good to excellent results without surgery, with most returning to practice in about 9 weeks.
Is there a risk of infection when using leeches in treatment?
Yes, but Dr. Hermansdorfer's research helps identify effective antibiotics to manage and prevent infections related to leech therapy.

Publications in plain English

Nonoperative management of complete tears of the medial collateral ligament of the knee in intercollegiate football players.

1990

Clinical orthopaedics and related research

Indelicato PA, Hermansdorfer J, Huegel M

Plain English
This study looked at 28 college football players who suffered complete tears of a knee ligament called the medial collateral ligament (MCL). After treating all of them without surgery through physical therapy and limited movement, the researchers found that 20 out of 21 players had good to excellent results after an average of 46 months, with most returning to full contact practice in about 9 weeks. The study highlights that avoiding surgery can be effective for MCL tears as long as there isn't additional damage to other ligaments. Who this helps: This helps athletes and their medical teams make informed decisions about treating MCL injuries without surgery.

PubMed

Antibiotic sensitivities of Aeromonas hydrophila cultured from medicinal leeches.

1988

British journal of plastic surgery

Hermansdorfer J, Lineaweaver W, Follansbee S, Valauri FA, Buncke HJ

Plain English
This study looked at how a bacteria called Aeromonas hydrophila, found in medicinal leeches, responds to different antibiotics. Researchers tested 20 leeches and found that the bacteria are resistant to penicillin and some early antibiotics but respond well to gentamicin, tetracycline, and certain modern antibiotics like cefamandol and cefoxitin. This is important because it helps doctors choose the right antibiotics to prevent infections in patients who have undergone surgeries involving leeches. Who this helps: Patients undergoing surgeries that use medicinal leeches for treatment.
