Summary
First metatarsophalangeal implants showed high complication rates but favorable patient satisfaction. Further multicentered studies are recommended to determine the true incidence of complications.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
Background:
- First metatarsophalangeal joint arthroplasty is a common procedure.
- Implant survival and complication rates are critical for long-term outcomes.
Purpose of the Study:
- To evaluate the subjective and objective outcomes of first metatarsophalangeal implants.
- To report the incidence of complications associated with these implants.
Main Methods:
- Retrospective analysis of 19 first metatarsophalangeal implants in 15 patients.
- Follow-up averaged 5.9 years.
- Radiographic and clinical evaluations were performed.
Main Results:
- High incidence of complications including implant deformation, bony erosions, and bony encroachment.
- Postoperative pain, stiffness, and restricted motion were common.
- Despite objective findings, patient satisfaction was very favorable.
Conclusions:
- First metatarsophalangeal implants may have a high complication rate.
- Patient satisfaction can be high despite objective limitations.
- Multicentered studies are needed to establish true complication incidence.
