A total of 143 BioPro Modular Thumb Implant joint replacements were reviewed at an average of 72 months (6 years) post-operatively. At the latest follow-up, pain relief occurred in (94%) 135 thumbs, function improved in (96.5%) 138 thumbs, (97%) 139 thumbs were excellent or good in overall assessment, and (99%) 142 thumbs had good or excellent cosmetic appearance. The mean tip pinch improved from 4.9 kg preoperatively to 6.44 kg postoperatively. The authors reported a shorter recovery time compared to the traditional LRTI (12 weeks vs 22 weeks). There were a total 6 thumbs (4%) that required revision surgery. The revisions included four thumbs successfully revised to a longer stem due to loosening, one revised to a larger head due to instability, and one revised to an LRTI. There were no complete dislocations observed.
Hemiarthroplasty Successfully Treats Thumb Basilar Arthritis

Presented at the Academy of Orthopedic Surgeons Annual Meeting 2017
A retrospective review of a total of 63 thumbs was available for follow-up at an average of 43.5 months (range 8 to 106 months). Group strength testing showed a return of strength to the same or greater than the non-operative thumb and the average QuickDASH improved from 49 to 26. The implant survivorship was 92.5%.
The BioPro Thumb Carpometacarpal Hemiarthroplasty: Case Series and Surgical Technique
Techniques in Hand & Upper Extremity Surgery
A study examined the effectiveness of the BioPro prosthesis, a specialized implant for treating thumb joint arthritis. This surgical procedure preserves the trapezium bone and allows for future revision surgeries if needed.
The research analyzed 11 patients who received this thumb implant between 2018-2021 at a U.S. community medical center. The patient group included 6 females, with an average age of 64.8 years. Most patients worked in office settings, with some being healthcare workers, retirees, or homemakers.
Before surgery, patients reported severe pain levels averaging 8 out of 10. After surgery, pain levels decreased significantly to 1 out of 10, with follow-up occurring around 23 months post-operation. The success rate was notable – 8 out of 11 patients would recommend the procedure to others.
Only one patient experienced ongoing pain issues, traced to improper implant placement. This case required additional surgery to remove the implant. Overall, 10 out of 11 patients showed positive outcomes after one year, with good pain relief and functional improvement. The BioPro implant demonstrated both safety and effectiveness, with minimal risk of joint displacement.
