Trapeziometacarpal joint replacement with the Arpe prosthesis.

Area of Science:

• Orthopedic surgery
• Biomaterials science
• Rehabilitation medicine

Background:

• Trapeziometacarpal joint osteoarthritis significantly impacts hand function and quality of life.
• Non-cemented total joint replacement is an option for managing advanced trapeziometacarpal joint arthritis.
• The Arpe prosthesis is a specific implant used for this procedure.

Purpose of the Study:

• To evaluate the subjective outcomes of non-cemented total joint replacement using the Arpe prosthesis.
• To determine the five-year survival rate of the Arpe prosthesis in trapeziometacarpal joint arthroplasty.
• To assess patient-reported functional and pain outcomes post-surgery.

Main Methods:

• A cohort of 49 hands underwent non-cemented total joint replacement with the Arpe prosthesis.
• Subjective outcome scores, including DASH and VAS for pain and satisfaction, were collected.
• Follow-up data was analyzed for prosthesis survival and complications.

Main Results:

• Mean follow-up was 6 years for 35 prostheses.
• Excellent patient-reported outcomes: low DASH scores (8), low pain (VAS 1), high satisfaction (9.6), and willingness to repeat (9.8).
• Five-year prosthesis survival was 97% (33 out of 34 hands); 5% dislocations and 4 implant removals were noted.

Conclusions:

• The Arpe prosthesis provides satisfactory mid-term results for trapeziometacarpal joint replacement.
• High patient satisfaction and functional improvement are associated with this implant.
• The Arpe prosthesis exhibits a favorable five-year survival rate in this patient cohort.
