Hasenclever Index Calculator

The Hasenclever Index Calculator can be used to assess the risk of avulsion of the patellar tendon during anterior cruciate ligament (ACL) reconstruction.

Input Parameters

Calculation Results

Hasenclever Index Calculation

Hasenclever Index = Age / (Weight / Height)

Where:
Age: Age of the patient in years
Weight: Weight of the patient in kilograms
Height: Height of the patient in centimeters

Result

--

A Hasenclever Index greater than 3.0 indicates a higher risk of patellar tendon avulsion.

Hasenclever Index Calculator Calculator Usage Guide

Learn how to use the Hasenclever Index Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the patient's age in years.
  2. Enter the patient's weight in kilograms.
  3. Enter the patient's height in centimeters.
  4. Select the patient's gender.
  5. Click the "Calculate" button to compute the Hasenclever Index.

Interpreting the Results

A Hasenclever Index greater than 3.0 indicates a higher risk of patellar tendon avulsion during anterior cruciate ligament (ACL) reconstruction. This index helps in planning surgical approaches and techniques to minimize the risk of avulsion.

Working Principle

The Hasenclever Index is calculated by dividing the patient's age by the ratio of their weight to height. This ratio helps in assessing the biomechanical stress on the patellar tendon relative to the patient's body composition.
