Body Mass Index and Joint Replacement Surgery

Calculate Your BMI

What Is Body Mass Index [BMI]

Your BMI is a measurement of your body weight based on your height and weight. Although your BMI does not actually “measure” your percentage of body fat, it is a useful tool to estimate a healthy body weight based on your height. Due to its ease of measurement and calculation, it is the most widely used diagnostic indicator to identify a person’s optimal weight depending on his height. Your BMI “number” will inform you if you are underweight, of normal weight, overweight, or obese. However, due to the wide variety of body types, the distribution of muscle and bone mass, etc., it is not appropriate to use this as the only or final indication for diagnosis.

The formulas to calculate BMI based on two of the most commonly used unit systems:

BMI = weight(kg) / height(m) (Metric Units)
BMI = 703·weight(lb) / height(in) (U.S. Units)

BMI Table for Adults

This is the World Health Organization’s (WHO) recommended body weight based on BMI values for adults. It is used for both men and women, age 18 or older. The Body mass chart for adults and the body mass chart for children is different. This is because body mass index is accounted differently based on age and growth spurts. Here is the Body Mass Index Chart for women and for men that are 18 and older:

Anesthesia for Hip and Knee Surgery

Pain control is a major concern for many joint replacement surgery candidates. Surgeons and anesthesiologists utilize a combination of advanced anesthesia techniques to optimize pain control and improve hip and knee replacement outcomes. Advanced anesthesia procedures at the Bone and Joint Institute means improved pain control and shorter hospital stays for most joint replacement patients.

Relief for Stiff Joints

Do your hips and knees feel stiff when you wake up in the morning or after sitting for a period of time? There are several reasons why prolonged inactivity may cause joint stiffness and pain. From home treatments to surgical intervention, Dr. Cory Calendine discusses 13 ways to find relief from stiff joints.

How Is Direct Anterior Approach Hip Replacement Done?

Direct Anterior Approach (DAA) hip replacement is a revolutionary minimally invasive surgical technique that accesses the hip joint through a precise 3-4 inch incision extending from the Anterior Superior Iliac Spine toward the lateral epicondyle. Unlike traditional hip replacement methods, DAA utilizes the natural intermuscular interval between the tensor fasciae latae and sartorius muscles, preserving muscle integrity without cutting through major muscle groups. The procedure involves positioning the patient supine on a specialized fracture table, carefully dissecting through anatomical layers, and using specialized retractors to access the hip joint while maintaining tissue preservation. This muscle-sparing approach enables same-day discharge, immediate weight-bearing, and significantly faster recovery times, with patients achieving independent mobility up to six days earlier than traditional hip replacement surgery. The technique combines intraoperative fluoroscopy for optimal implant placement with reduced post-operative pain, lower dislocation rates, and improved patient satisfaction, making it the preferred choice for modern total hip arthroplasty procedures.
