Our Research

Key Finding: Ankle ArtCart is an effective treatment for ankle injury and OA based on at least 2 years of follow-up for five patients.

Key Finding: Meniscus transplantation produced lasting improvements in pain and knee function, and about 74% of patients were able to return to sports. The transplanted meniscus was estimated to remain successful for an average of 12.6 years, despite these patients already having substantial cartilage damage.

Key Finding: Articular cartilage paste grafting offers a feasible method of lesion repair and meaningful short-term improvements in patient pain, function, and activity.

Key Finding: The arthroscopic three tunnel technique for meniscal allografting enables accurate placement and stable fixation of medial and lateral allografts to the tibia at 3 sites.

Key Finding: Meniscus allograft transplantation can reliably survive and improve symptoms in knees with advanced unicompartmental arthritis.

Key Finding: ArtCart resulted in significant improvements in patient pain, function, and activity with approximately 63.6% of patients experiencing restoration of the articular surface and 27.3% of patients regrowing normal hyaline cartilage.

Key Finding: Height, weight, and gender are practical and easily obtained variables that correlate with tibial plateau width and meniscal size.

Key Finding: Meniscus allograft transplants can reliably survive and provide meaningful symptom improvement, even in arthritic joints.

Key Finding: Collagen meniscus implantation is a means of biologic reconstruction of complex tears in the meniscus, demonstrating a method of functional joint preservation in patients with complex meniscus tears.

Key Finding: 79.9% of procedures were intact at a mean follow-up time of 5.8 years. Kaplan-Meier estimated mean survival time was 9.9 years in patients undergoing meniscal allograft transplantation with concomitant articular cartilage repair.

Key Finding: Patients with OCD treated with osteochondral graft were able to successfully regain knee function and experienced a reduction in pain.

Key Finding: 50% of hip/knee OA guideline reccommendations were based on low-quality evidence; 46% don't disclose conflicts of interest.

Key Finding: Median benefit time of 19.1 years; 90% reported good-excellent pain relief; delayed arthroplasty to mean age 60.2 years.

Key Finding: Morselization increases chondrocyte proliferation 34-80%; contradicting long-held beliefs that impaction trauma leads to cell death.

Key Finding: First demonstration that "humanized" porcine ligament can remodel into functional autologous ACL over 20 years.

Key Finding: The 3-incision allograft quadriceps tendon technique provides a reproducible approach for ACL reconstruction while avoiding tissue harvest from the patient's own patellar tendon or hamstrings.

Key Finding: Meniscus allograft transplantation with biologic knee restoration improved pain and function in patients over 50 years old. Patients who progressed to knee replacement delayed the need for one by a mean time of 8.64 years.
