Use of RegJoint™ -implant in foot surgery (2022)
Dr. Kathryn Hassel and colleagues published a review on the use of the bioabsorbable RegJoint™ implant in foot surgery. Made of poly-L/D-lactide (PLDLA), the implant serves as a temporary scaffold that is gradually replaced by the body’s own connective tissue within 2–3 years.
Applications and Results:
- Hallux rigidus (MTP I osteoarthritis):
RegJoint™ improved pain and function compared to traditional resection arthroplasty. Long-term follow-up (14 years) showed good preservation of joint space. - Köhler’s disease type II (osteonecrosis of the second metatarsal):
The implant was used when bone wedge surgery was not feasible. Patients reported pain relief and improved function (AOFAS score increased from 47 to 82). - Calcaneonavicular coalition (osseous or fibrous fusion in the foot):
RegJoint™ replaced muscle or fat grafts, avoiding secondary wounds, prolonged immobilization, and permanent muscle changes.
In a series of 8 patients, no complications or recurrence were observed.
Conclusion:
RegJoint™ offers a complication-free and anatomically preserving alternative in foot surgery. It may reduce wound issues, accelerate recovery, and maintain functional anatomy. The only notable drawback mentioned was the implant’s cost.
