Dr. Tenholder studies various aspects of knee replacement surgeries, particularly the effectiveness of minimal-incision techniques. He explores how these methods can improve recovery for patients, especially for those with specific body types. His research also delves into managing blood loss during surgeries to minimize the need for blood transfusions, ensuring safer procedures. Beyond knee surgery, he has explored solutions for children with amputations, looking at ways to reduce complications from abnormal limb growth.
Key findings
In a study of 106 knee replacement surgeries, the size of the incision did not affect the frequency of patellar lateral releases, highlighting the viability of minimal incisions in surgery.
58% of patients who underwent minimal-incision total knee arthroplasty experienced improved outcomes, including reduced need for blood transfusions and enhanced knee mobility.
The use of synthetic PTFE caps in juvenile amputation cases led to only 29% needing further surgery after almost 5 years, compared to 86% using traditional methods.

Publications in plain English
Incidence of lateral release in total knee arthroplasty in standard and mini-incision approaches.
2006
Clinical orthopaedics and related research
Cook JL, Scuderi GR, Tenholder M
Plain English This study looked at the number of times patellar (kneecap) lateral release was performed during knee replacement surgeries using either a standard or a mini incision. Out of 106 surgeries, the researchers found that the size of the incision did not affect how often lateral release was done. Understanding this is important because it helps assess whether minimally invasive techniques can be used without changing outcomes in knee surgery.
Who this helps: This helps surgeons and patients considering knee replacement options.
Minimal-incision total knee arthroplasty: the early clinical experience.
2005
Clinical orthopaedics and related research
Tenholder M, Clarke HD, Scuderi GR
Plain English This study looked at a new method for knee replacement surgery called minimal-incision total knee arthroplasty, focusing on which patients are best suited for this approach. Researchers found that 58% of the patients had smaller incisions and better outcomes, such as less need for blood transfusions and better knee movement after surgery. This matters because it suggests that certain patients, particularly thinner women with narrow femurs, may benefit from a less invasive surgery that leads to quicker recovery.
Who this helps: Patients needing knee replacements, especially those fitting the ideal profile.
Surgical management of juvenile amputation overgrowth with a synthetic cap.
2004
Journal of pediatric orthopedics
Tenholder M, Davids JR, Gruber HE, Blackhurst DW
Plain English This study looked at 17 amputations in 14 children who had problems with leftover limb growth. Researchers used a synthetic material called PTFE to cap the limbs, and found that after almost 5 years, the need for further surgery was much lower with PTFE caps compared to traditional methods: only 29% needed another operation with PTFE caps compared to 86% for the old method. This matters because it shows that PTFE caps can provide better long-term results for children facing these issues.
Who this helps: This helps children with amputations experiencing limb overgrowth.
Intraoperative blood management in joint replacement surgery.
2004
Orthopedics
Tenholder M, Cushner FD
Plain English This study looked at ways to manage blood loss during joint replacement surgery to reduce the need for blood transfusions. It found that techniques like using specialized equipment and medications can significantly decrease the amount of blood lost during the procedure. This is important because it means fewer patients will need blood transfusions, which is safer and better for their recovery.
Who this helps: Patients undergoing joint replacement surgery, especially those with specific medical needs or concerns.
Surgical approaches in mini-incision total knee arthroplasty.
2004
Clinical orthopaedics and related research
Scuderi GR, Tenholder M, Capeci C
Plain English This study looked at different surgical techniques for performing total knee replacement using smaller incisions. It found that the medial parapatellar approach is the most flexible option among these techniques, but the success of the surgery relies on choosing the right patients for this method. This is important because smaller incisions can lead to quicker recovery times and less pain for patients.
Who this helps: Patients needing knee replacement surgery.
Gene expression in older rats with delayed union of femoral fractures.
2003
The Journal of bone and joint surgery. American volume
Meyer RA, Meyer MH, Tenholder M, Wondracek S, Wasserman R +1 more
Plain English This study looked at how older rats heal when they break a bone compared to younger rats. Researchers found that while younger rats' fractures healed in about four weeks, older rats took more than twenty-six weeks to heal. The study noted that older rats had lower levels of certain important genes related to bone healing, which could explain their delayed recovery.
Who this helps: This research benefits doctors treating older patients with fractures, helping them understand the healing challenges faced by this age group.
