Patient Perspectives After Trapeziectomy Versus Carpometacarpal Prosthesis: A Qualitative Thematic Analysis of Ten...

Background: Carpometacarpal (CMC-I) arthritis is a frequent and disabling condition. Standard surgical options include trapeziectomy and prosthetic arthroplasty. While quantitative outcomes have been widely studied, little is known about patient perspectives regarding function, aesthetics, and rehabilitation. Methods: We conducted semi-structured interviews with ten patients who had undergone trapeziectomy on one side and prosthesis implantation on the contralateral side. Interviews were performed ≥6 months postoperatively, audio-recorded, transcribed verbatim, and analyzed thematically following Braun and Clarke's framework. Researcher triangulation and member checking were applied to enhance trustworthiness. Results: Four overarching themes were identified. (1) Strength: Most patients reported greater strength and endurance on the prosthetic side, though both hands were generally adequate for daily activities. (2) Rehabilitation: Recovery after prosthesis implantation was described as markedly faster and less burdensome, with reduced need for therapy compared to trapeziectomy. (3) Aesthetics: Trapeziectomy was often associated with dissatisfaction due to thumb shortening and collapse, while prostheses were perceived as restoring a more natural appearance. (4) Surgical preference: When asked which procedure they would hypothetically choose again, all participants favored prosthesis implantation, citing superior function, faster recovery, and more favorable aesthetics. Conclusions: Patients who experienced both procedures consistently preferred prosthesis implantation. Their narratives highlight dimensions beyond standard clinical scores, including rehabilitation burden, appearance, and psychosocial impact. Incorporating patient-reported outcomes into surgical counseling is essential to align treatment of CMC-I arthritis with patient priorities and to support shared decision-making.
