A Physiotherapist’s Guide to Osteoarthritis
“Arthritis” is a term used to describe inflammation of the joints. Osteoarthritis (OA) is the most common form of arthritis and usually is caused by the deterioration of a joint. Typically, the weight-bearing joints are affected, with the knee and the hip being the most common.
An estimated 27 million Americans have some form of OA. According to the Centers for Disease Control and Prevention, 1 in 2 people in the United States may develop knee OA by age 85, and 1 in 4 may develop hip OA in their lifetime. Until age 50, men and women are equally affected by OA; after age 50, women are affected more than men. Over their lifetimes, 21% of overweight and 31% of obese adults are diagnosed with arthritis.
OA affects daily activity and is the most common cause of disability in the US adult population. Although OA does not always require surgery, such as a joint replacement, it has been estimated that the use of total joint replacement in the United States will increase 174% for hips and 673% for knees by 2030.
Physical therapists can help patients understand OA and its complications, and provide treatments to lessen pain and improve movement. Additionally, physical therapists can provide information about healthy lifestyle choices and obesity education. This is important because some research shows that weight loss can reduce the chance of getting OA. One study showed that an 11-pound weight loss reduced the risk of OA in women.
What is Osteoarthritis?
Your bones are connected at joints such as the hip and knee. A rubbery substance called cartilage coats the bones at these joints and helps reduce friction when you move. A protective oily substance called synovial fluid is also contained within the joint, helping to ease movement. When these protective coverings break down, the bones begin to rub together during movement. This can cause pain, and the process itself can lead to more damage in the remaining cartilage and the bones themselves.
The cause of OA is unknown. Current research points to aging as the main cause. Factors that may increase your risk for OA include:
•Age. Growing older increases your risk for developing OA because of the amount of time you’ve used your joints.
•Genetics. Research indicates that some people’s bodies have difficulty forming cartilage. Individuals can pass this problem on to their children.
•Past Injury. Individuals with prior injury to a specific joint, especially a weight-bearing joint (such as the hip or knee), are at increased risk for developing OA.
•Occupation. Jobs that require repetitive squatting, bending, and twisting are risk factors for OA. People who perform jobs that require prolonged kneeling (miners, flooring specialists) are at high risk for developing OA.
•Sports. Athletes who repeatedly use a specific joint in extreme ways (pitchers, football linemen, ballet dancers) may increase their risk for developing OA later in life.
•Obesity. Being overweight causes increased stress to the weight-bearing joints (such as knees), increasing the risk for development of OA.
How Does it Feel?
Typically, OA causes pain and stiffness in the joint. Common symptoms include:
•Stiffness in the joint, especially in the morning, which eases in less than 30 minutes
•Stiffness in the joint after sitting or lying down for long periods
•Pain during activity that is relieved by rest
•Cracking, creaking, crunching, or other types of joint noise
•Pain when you press on the joint
•Increased bone growth around the joint that you may be able to feel
Caution: Swelling and warmth around the joint is not usually seen with OA and may indicate a different condition or signs of an inflammation. Please consult with your doctor if you have swelling, redness, and warmth in the joint.
How Is It Diagnosed?
Osteoarthritis is typically diagnosed by your doctor using an x-ray, but there are signs that may lead your physical therapist to suspect you have OA. Joint stiffness, difficulty moving, joint creaking or cracking, and pain that is relieved with rest are typical symptoms.
How Can a Physical Therapist Help?
Your physical therapist can effectively treat OA. Depending on how severe the OA is, physical therapy may help you avoid surgery. Although the symptoms and progression of OA are different for each person, starting an individualized exercise program and addressing risk factors can help relieve your symptoms and slow the condition’s advance. Here are a few ways your physical therapist can help:
•Your therapist will do a thorough examination to determine your symptoms and what activities are difficult for you. He or she will design an exercise program to address those activities and improve your movement.
•Your therapist may use manual (hands-on) therapy to improve movement of the affected joint.
•Your physical therapist may offer suggestions for adjusting your work area to lessen the strain on your joints.
•Your physical therapist can teach you an aerobic exercise program to improve your movement and overall health, and offer instructions for continuing the program at home.
•If you are overweight, your physical therapist can teach you an exercise program for safe weight loss, and recommend simple lifestyle changes that will help keep the weight off.
In cases of severe OA that are not helped by physical therapy alone, surgery, such as a knee or hip replacement, may be necessary. Your physical therapist will refer you to an orthopedic surgeon to discuss the possibility of surgery.
Can this Injury or Condition be Prevented?
The best way to prevent or slow the onset of OA is to choose a healthy lifestyle, avoid obesity, and participate in regular exercise.
The American Physical Therapy Association (APTA) believes that consumers should have access to information that could help them make health care decisions and also prepare them for their visit with their health care provider.

Sports Injury Prevention for Baby Boomers
While there may be no single fountain of youth, you can slow down the aging process by staying physically active. Regular exercise enhances muscle and joint function, keeps bones strong, and decreases your risk of heart attack and stroke.
Here are some tips developed by the American Orthopaedic Society for Sports Medicine and American Academy of Orthopaedic Surgeons that can help you exercise safely.
Always take time to warm up and stretch before physical activity. Research studies have shown that cold muscles are more prone to injury. Warm up with jumping jacks, stationary cycling or running or walking in place for 3 to 5 minutes. Then slowly and gently stretch, holding each stretch for 30 seconds. Do not stretch cold muscles.
Just like warming up, it is important to cool down. Gentle stretching after physical activity is very important to prepare your body for the next time you exercise. It will make recovery from exercise easier.
Consistent Exercise Program
Avoid the “weekend warrior” syndrome. Compressing your exercise into 2 days sets you up for trouble and does not increase your fitness level. Try to get at least 30 minutes of moderate physical activity every day. If you are truly pressed for time, you can break it up into 10-minute chunks. Remember that moderate physical activity can include walking the dog, working in the garden, playing with the kids and taking the stairs instead of an elevator. Parking on the far end of a parking lot will increase the distance you have to walk between your car and your destination.
Take sports lessons. Whether you are a beginner or have been playing a sport for a long time, lessons are a worthwhile investment. Proper form and instruction reduce the chance of developing an “overuse” injury like tendinitis or a stress fracture.
Lessons at varying levels of play for many sports are offered by local park districts and athletic clubs.
Invest in good equipment. Select the proper shoes for your sport and use them only for that sport. When the treads start to look worn or the shoes are no longer as supportive, it is time to replace them.
Listen to Your Body
As you age, you may find that you are not as flexible as you once were or that you cannot tolerate the same types of activities that you did years ago. While no one is happy about getting older, you will be able to prevent injury by modifying your activity to accommodate your body’s needs.
Use the Ten Percent Rule
When changing your activity level, increase it in increments of no more than 10% per week. If you normally walk 2 miles a day and want to increase your fitness level, do not try to suddenly walk 4 miles. Slowly build up to more miles each week until you reach your higher goal. When strength training, use the 10% rule as your guide and increase your weights gradually.
Develop a balanced fitness program that incorporates cardiovascular exercise, strength training, and flexibility. In addition to providing a total body workout, a balanced program will keep you from getting bored and lessen your chances of injury.
Add activities and new exercises cautiously. Whether you have been sedentary or are in good physical shape, do not try to take on too many activities at one time. It is best to add no more than one or two new activities per workout.
If you have or have had a sports or orthopaedic injury like tendinitis, arthritis, a stress fracture, or low back pain, consult your Physiotherapist who can help design a fitness routine to promote wellness and minimize the chance of injury.
Ok so your shoulder has been hurting for a while and your Physio has diagnosed you with a Rotator Cuff injury. What the hell is a rotator cuff? How do I get rid of this pain!?
Firstly, the rotator cuff is a group of four muscles which help to stabilise the shoulder. The shoulder is a ball and socket joint, similar to the hip, however the shoulder has a shallow socket in comparison. What the shoulder lacks in stability it makes up for in mobility, generally speaking, a healthy shoulder has almost 360 degrees of movement so it needs help from the surrounding muscles to maintain stability through movement. There is also another structure inside the shoulder joint called the labrum, which helps to deepen the joint and provide stability.
How does my Rotator Cuff get injured?
Rotator cuff injuries usually occur either acutely (immediate sharp pain) or over time (gradual increasing dull ache). Acute rotator cuff injuries can often involve a tearing of the rotator cuff tendons and leads to pain and weakness of the shoulder. Gradual onset of shoulder pain can be associated with repetitive overhead movements, which can lead to smaller tears in the tendon and inflammation around this area.
One of the main factors which can influence shoulder pain is the position of the shoulder. The further forward the humeral head (the ball) sits in the socket, the more compression of the tendon occurs and leads to injury.
How can I fix it?
Having your shoulder properly assessed by a qualified Physiotherapist is the first step in diagnosing a Rotator Cuff injury. Investigations such as Ultrasound or MRI may be relevant if the Physiotherapist feels there is significant injury. For acute rotator cuff tears, a small period of immobilisation in a sling or in some cases, just with some tape, will help settle the pain. Once pain and inflammation are under control then you need to get the shoulder moving and gradually strengthen the rotator cuff tendons and surrounding muscles.
For the gradual onset type shoulder pain there is usually a biomechanical cause for the loading of the tendons. Thorough assessment by a qualified Physiotherapist is a must to get to the bottom of your shoulder pain. Initially settling down the pain and inflammation around the tendons and encouraging gentle pain free movement is the first step. Then gradually increasing the load in the shoulder until the strength is back to normal
How can I prevent this from happening in the future?
Continuation of the strength and flexibility exercises prescribed by your Physiotherapist will help decrease the likelihood of re-occurrence. Identifying aggravating positions i.e. overhead movements or reaching in awkward positions will also decrease the likelihood of re-injury. If your job is a relatively sedentary and requires hours of sitting at a time, trying to break up your day with standing/walking will help, also an ergonomic assessment to ensure your workspace is properly set up to suit you will help ease the stress on your shoulders/neck.
Frozen shoulder, correctly known as Adhesive Capsulitis, presents as a combination of shoulder pain and stiffness causing sleep disturbance and marked disability.
In a frozen shoulder the capsule surrounding the shoulder joint is more thickened than normal and it shrinks, adhering to the humerus (arm bone) and itself – hence the name adhesive capsulitis. It is associated with inflammation, causing pain followed by scarring, causing stiffness.
Clinical features of frozen shoulder
Gradual onset of arm pain.
Unable to lie on affected side.
Restriction of movements, usually into elevation and outward rotation.
Diagnosed by a thorough shoulder examination.
X-rays may rule out other causes of shoulder pain but are unable to diagnose a frozen shoulder.
Runs a distinct course which can be broken into 4 phases or simply “pain-predominant” and “stiffness-predominant”.
Phases of frozen shoulder
Phase 1: Usually pain.
Phase 2: Increasing pain and increasing stiffness but still predominantly pain.
Phase 3: Pain abates, leaving stiffness.
Phase 4: Resolution, usually by 2 years.
Who gets frozen shoulder?
Mostly occurs between ages 40 and 60 years.
More common in women and diabetics.
Often appears for no apparent reason but can stem from an injury to the shoulder or following shoulder surgery.
20% of patients will develop it in the other shoulder in the future but almost never occurs again in the same shoulder.
Common shoulder problems
Unable to: Reach above shoulder height
Throw a ball
Quickly reach for something
Reach behind your back e.g. doing up bra, tucking in shirt
Reach out to the side and behind e.g. reaching for seat belt
Sleep on your side
How can physiotherapy help?
Although a frozen shoulder is generally self-limiting, the aim of physiotherapy is to keep the shoulder joint as pain free and mobile as possible. Physiotherapy may also help reduce the time taken to move through each phase.
Phase 1 & 2- pain relieving techniques such as gentle mobilisation, muscle releases, dry needling, taping.
Phase 3- shoulder joint mobilisation and stretches, muscle release techniques, dry needling and exercises to regain range and strength. Treatment should not be too aggressive.
Phase 4- shoulder mobilisation and stretches followed by strength exercises to control and maintain the returning range of movement.
