Keller arthroplasty: a prospective review.

Area of Science:

• Orthopedic Surgery
• Podiatry
• Biomechanical Engineering

Background:

• Hallux valgus, commonly known as a bunion, is a prevalent foot deformity.
• Surgical interventions are often considered for symptomatic hallux valgus when conservative treatments fail.
• The Keller procedure is one surgical option for addressing hallux valgus, particularly in older populations.

Purpose of the Study:

• To prospectively evaluate the efficacy of the Keller procedure for treating hallux valgus.
• To assess the impact of the surgery on patient symptoms, function, cosmesis, and deformity.
• To determine the overall patient satisfaction rate following the Keller procedure.

Main Methods:

• A prospective study involving 44 female patients (75 feet) with hallux valgus.
• Average patient age was 66 years.
• Follow-up duration averaged 31 months (range: 12-64 months).

Main Results:

• The Keller procedure significantly improved symptoms like joint pain and bunion tenderness.
• Functional outcomes, including footwear and activity levels, showed improvement.
• A decrease in the hallux valgus deformity was observed.
• Metatarsal calluses were not influenced by the procedure.
• Postoperative cock-up deformity was common but did not negatively impact results.
• Overall patient satisfaction was 77%.

Conclusions:

• The Keller procedure is an effective surgical option for hallux valgus in older female patients.
• The surgery leads to significant improvements in pain, function, and cosmetic appearance.
• Despite common postoperative deformities, patient satisfaction is generally high, indicating a favorable risk-benefit profile.
