Knee Joint Replacement – Carrollton, TX

by Craig W. Goodhart, MD 24. April 2017 10:33

With aging or due to certain medical conditions like Osteoarthritis, the cartilages in the knee joint degrade and cause the bones to rub against each other. This friction leads to excruciating pain and limits the functionality of the joint. Knee joint replacement or knee arthroplasty is a surgical procedure of replacing the damaged structures with artificial metal implants.

Types Of Knee Replacement

  • Partial Knee Replacement - In this procedure, the surgeon may remove only the damaged portion of the knee. The process requires less time and only a small incision has to be made at the affected area. The recovery period for partial knee replacement is less and patient may be able to walk again with a fully functional joint really soon.
  • Total Knee Replacement – The procedure involves complete removal of the damaged cartilage. The orthopedic surgeon may encase the ends of the damaged bones in metal or plastic coverings. In some cases even the undersurface of the kneecap is replaced by a plastic surface. After the procedure the doctors may suggest certain rehabilitation exercises that will help to regain the lost functionality of knee joint.

Who is a candidate for Knee Replacement?

A surgery may be recommended to the patients who -

  • Have constant knee pain
  • Suffer from Rheumatoid Arthritis
  • Have deformed legs
  • Suffered from a severe knee injury
  • Benefits Of Knee Replacement Surgery –
  • Pain alleviation
  • Enhanced mobility
  • Improved quality of life

Recovery Period After Knee Replacement Surgery –

It may take around 3 months to become weight bearing and in 6 months the patients can regain full mobility of the joint. During the recovery period, the patients must remain careful and take certain precautions. The legs must not be pivoted or twisted and while lying on bed they must be kept as straight as possible. Even if the patient experience reduction in pain, he/she must not start a strenuous exercise like squatting, running or any other form that requires excessive kneeling.

Orthopedic Treatment For Kneecap Instability

by Craig W. Goodhart, MD 26. October 2016 08:23

Kneecap or Patella, is one of the three bones that constitute the knee joint. When the knee bends and straightens, the kneecap smoothly slides up and down within a v-shaped groove at the end of the thigh bone. Sometimes, due to a fall or a blow, the patella can dislocate, either completely or partially.

When the patella slides out of place, it causes pain and loss of activity. It is necessary to seek medical attention, even if the patella slides back into position on its own.


There are several causes that result in Kneecap Instability. People having an abnormality in the knee, are more prone to the condition. Some of the common causes of instability are:

  • The femur (thighbone) may be shallow or uneven, increasing the chances of dislocation.
  • Loose ligaments make the joints extremely flexible, thus increasing the chances of patellar dislocation. Girls are more prone to this type of kneecap instability in caparison to boys.
  • Children with cerebral palsy and Down syndrome have weak muscles. This may cause their kneecaps to dislocate frequently due to imbalance.
  • In some rare cases, children can be born with unstable kneecaps that cause their kneecaps to dislocate at a very young age. This is usually painless.


  • Shifting or sliding of the kneecap out of the grove
  • Sitting and simple activities cause pain
  • Patella usually dislocates with a popping sound
  • Swelling and/or stiffness
  • Deformity of the knee
  • Cracking sound on movement or while changing direction


Non-surgical treatment

  • The first step in treating an unstable knee requires taking the child to the Emergency Room. The doctor may perform the ‘reduction’ treatment. This involves giving pain medication to the patient which helps relax the knee muscles. Then the doctor applies a gentle pressure to move the kneecap back into place. In some cases, reduction may occur naturally.
  • Wearing a brace. The doctor may recommend wearing a brace for about a month to help stabilize the knee, while it slowly heals.
  • Crutches. Putting weight on the knees can slow down the healing process and increase the pain in the knee. Thus, the doctor may suggest using crutches for a couple of weeks following the injury.
  • Once dislocated, the possibility of recurring instability of the kneecap increases. Regular exercises may help straighten the thigh muscles and reduces the risk.

Surgical treatment

In chronic cases, the patella may not stabilize with the help of non-surgical treatment. The doctor may recommend surgery to line up the kneecap into place and to tighten the loose tendons and knee muscles. The type of surgery depends on the extent of damage occurred.

Shoulder Instability: Orthopedic Carrollton

by Craig W. Goodhart, MD 23. April 2016 10:37

The shoulder is one of the most mobile joints in the human body as it enables the movement of the arm in many directions. This extensive range of motion also makes it prone to dislocations and injuries. The shoulder joint comprises of the humerus (upper arm bone), scapula (shoulder blade) and the clavicle (collar bone). The humerus is rounded at the top and rests in a socket shaped cavity within the scapula.

Shoulder Instability or loose shoulder is a condition that occurs when the upper part of the humerus slips out of the socket in the shoulder joint. It is termed as partial dislocation or subluxation if the humerus is partially displaced and total displacement if it slips out completely. Patients with Shoulder Instability, are more likely to suffer from repeated injuries and joint dislocation.


  • Shallow or flattened socket
  • Muscle weakness
  • Stretching and consequent loosening of ligaments
  • Prolonged immobilization of the joint
  • Sudden trauma or injury to the shoulder or arm
  • Bankart Lesion- tearing of the cartilage that lines the socket
  • Repeated overhead movements such as in swimming or tennis
  • Inherent anatomical disorders
  • Impaired neuromuscular control
  • Lifting a heavy weight or an awkward position while moving the arm


  • Pain
  • Weakness and instability in the arm and shoulder
  • Numbness
  • Swelling
  • Repeated instances of the shoulder giving away
  • Tenderness in the shoulder when touched
  • Inability to lift things or move the arm away from the body
  • Discomfort while sleeping on the affected shoulder


  • Evaluation of the patient’s medical history and daily activities
  • Physical examination of the Dislocated Shoulder
  • X-ray imaging
  • MRI scan may be done to evaluate the condition of muscles, ligaments, tendons and nerves


  • Activities that may aggravate pain or discomfort should be avoided
  • Heat or ice packs may be used to reduce swelling and pain
  • Prescription of anti-inflammatory drugs and painkillers to provide relief from the symptoms
  • Torn or loose ligaments may be surgically stitched back to enhance stability
  • The shoulder and arm may be immobilized for a specific period of time post-surgery to aid healing
  • Range of motion exercises may be recommended by a physical therapist to regain strength and restore movement in the joint.

Rotator Cuff Injury: Orthopedic Treatment In Carrollton

by Craig W. Goodhart, MD 26. October 2015 15:05

The rotator cuff comprises of four muscles: supraspinatus, infraspinatus, subscapularis and teres minor that surround the shoulder joint. These muscles help in stabilizing the shoulder joint. Damage to any or all of these muscles and the ligaments can limit the movement of the joint and can lead to rotator cuff injury. There may be a partial or a complete ligament tear depending on the severity of the condition.


  • Major injury to the shoulder
  • Degeneration of the tendon tissue
  • Heavy lifting over a long period of time
  • Development of bone spurs in the bones around the shoulder
  • Playing sports that require repetitive arm movements such as baseball and tennis
  • Occupations such as house painting and carpentry
  • Genetic factors


  • Dull ache that penetrates the shoulder
  • Limited shoulder movement
  • Inability to reach behind your back
  • Difficulty in combing hair
  • Pain when lying on the side of the affected shoulder


Physical examination is done to locate the exact areas of swelling and pain. X-Rays are conducted to see if there are any broken bones or if you suffer from Arthritis within the shoulder joint. Advanced imaging tests such as MRI scan, arthrography or ultrasonography may also be conducted depending on the severity of the condition.


Persistent pain in the shoulder cuff needs to be immediately examined by a shoulder specialist. Following treatment options could be utilized:

  • Application of ice packs may help in reducing swelling. Rest is recommended along with administration of anti-inflammatory medications as it may help in eliminating pain.
  • Physical therapy: Gradual rehabilitation is enhanced by exercises that help in strengthening the rotator cuff. These may also help in providing flexibility to the shoulder joint.
  • Injection: Cortisone injections are given in case a patient suffers constant pain and extremely limited shoulder motion.
  • Surgery: Surgical intervention is required in case of severe injuries. Open surgery and arthroscopy are two available options.

For diagnosis and treatment of rotator cuff injuries, consult Dr. Goodhart. To schedule an appointment with the orthopedic sports surgeon in Carrollton, TX, you can call at (972) 899-4679 or visit 4780 North Josey Lane, Carrollton, Texas 75010.

Carrollton Orthopedic Treatment For ACL Injuries

by Craig W. Goodhart, MD 21. April 2014 09:01

The ACL or Anterior Cruciate Ligament is one of the four important ligaments which are attached to the human knee joint. The ACL has a big part to play when it comes to imparting strength and stability to the knee joint. Any injury to the ACL can be a serious problem as it can cause massive loss of balance and stability, and considerable pain. Depending on the gravity of the situation orthopedic surgeon in Flower Mound can choose to implement several healing measures to alleviate this condition. These might include non-surgical or surgical lines of treatment.


An injured or torn ACL is usually viewed as a sports-related condition. However, they can also occur in people who do not indulge in sports or related activities. Common causes are situations where the leg faces impact and damage resulting from falls, major collisions and specific injuries. The ACL can also tear partially or completely during pivoting on a knee or due to a bad landing from a height. Most commonly ACL injuries occur to sportsmen who indulge in sports involving a lot of physical contact.


One of the surest signs of an ACL tear is that fact that with a torn ACL, a person’s knees give way causing the person to collapse. This instability of the knee persists and people become completely unable to pursue any activity where pressure might be on the knee like walking or standing. There can also be a considerable amount of inflammation and pain when you sustain any kind of ACL injury.


The extent of ACL injuries can be diagnosed by a knee injury doctor with the help of special medical examination where diagnostic tests like MRIs and x-rays can help assess the situation. Also orthopedic doctors use a special test called a Lachman test which involves working the leg and knee joint in a specific way so as to put pressure on the ACL to correctly diagnose the extent of the damage.


For partial tears and with people who do not require heavy usage of the ACL, non-surgical avenues of treatment can be considered. In these cases, complete rest along with regular application of ice to the affected areas can be advised. Some oral medication for bringing down the swelling and reducing pain can also be prescribed. In more serious cases, the only option is ACL reconstruction surgery. The surgery is followed by suitable post-operative rehabilitation and pain management.
