Comparison of Surgical Blade No. 11 and Ophthalmic Knife in Idiopathic Clubfoot Patients

July 15, 2026 updated by: Muhammad Aamir Latif

Comparison of Effectiveness of Surgical Blade No. 11 and Ophthalmic Knife for Percutaneous Achilles Tendon Tenotomy in Idiopathic Clubfoot Patients

There is limited local data available on the comparison between surgical blade no.11 and ophthalmic knife among patients with neglected clubfoot going through tenotomy. The study has been planned with the objective of comparing the effectiveness of surgical blade no. 11 and ophthalmic knife for percutaneous Achilles tendon tenotomy in Idiopathic clubfoot patients

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Percutaneous Achilles tendon tenotomy is performed using surgical blade no. 11. However, concerns regarding incision size, bleeding, and scarring have led to exploration of alternative instruments. Previously, comparative studies have been conducted on a 22-gauge needle vs. a surgical blade. However, an ophthalmic knife, designed for microsurgical precision, offers a fine tip and elongated handle, allowing improved control during tendon release with a small incision and precision. Previous studies have compared blade and needle techniques and ophthalmic knives for percutaneous tenotomy of the Achilles tendon done on animals. The study findings would be helpful in opting for a better instrument for the procedure that should be effective and have a better safety profile.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Improvement in ankle dorsiflexion
Time Frame: 3 months after surgery
Frequency of patients who had improved Pirani score was noted.
3 months after surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Bleeding
Time Frame: 1 hour after surgery
Frequencies of patients who had bleeding severity as none, mild, moderate, or excessive, were noted.
1 hour after surgery
Infection
Time Frame: 3 months after surgery
The frequency of patients who had infected wound was noted.
3 months after surgery
Incomplete Tenotomy
Time Frame: 3 months after surgery
Frequency of patients who had incomplete release or residual deformity was assessed.
3 months after surgery
