Common Knee Injuries And How to Prevent Them

The knee is an important joint in the human body that comprises bones, ligaments, cartilage, muscles, and tendons. It bears the significant weight of our body and acts as a supporting structure. That is why it is prone to common injuries due to wear and tear, age, overuse, and other illnesses. This article discusses the different types of common knee injuries, knee pain symptoms, causes of knee injuries, how to treat knee injuries and ways on how to prevent them. 

Types of Common Knee Injuries

Knee injuries are generally common among active people and older individuals. The most common knee injuries include:

Meniscus Tears

When the cushions in the knee joint tear due to some accident, trauma, or overuse, it can result in a meniscus tear. Read more about meniscus tear treatment here.

ACL Tears

An ACL tear injury occurs when the anterior cruciate ligament in the knee joint gets injured or torn. Read more about ACL tear treatment. 

Patellar Tendinitis

Patellar tendinitis is an injury to the patellar tendon where the tendon becomes inflamed. This tendon acts along with the thigh muscles to help you kick, run, and jump. Patellar tendinitis might occur as a result of constant jumping.

Patellar Tendon Rupture

When the patellar tendon becomes torn as a result of severe trauma, it can cause a disabling injury, which may require immediate surgery.

Bursitis

Our knee joint comprises small fluid-filled sacs near the joint. Knee bursitis is an injury of the knee when these fluid-filled sacs become inflamed, causing pain and swelling.

Knee Dislocation

When the knee cap, also known as the patella, moves out of place, it is called knee dislocation. Its common symptoms include pain and instability in the knee. 

Sprains and Strains

When the tendons, ligaments, and muscles in the knee get overstretched or torn, it can be referred to as a sprain or strain. 

Patellofemoral pain syndrome

Patellofemoral pain syndrome refers to the condition when the nerves sense pain in the bone, joint, or soft tissues around the kneecap. Also called runner’s knee, it is characterised by knee pain, especially after sitting down with a bent knee for a long time, climbing or descending stairs, or after excessive knee usage.

Arthritis

Knee pain may also be a result of the different types of arthritis. For example, osteoarthritis is a degenerative disease that causes the knee cartilage to wear away, resulting in pain and inflammation. Similarly, rheumatoid arthritis is an autoimmune disease where the body’s immune system attacks the healthy tissues, causing knee pain and swelling. 

Causes of Knee Injuries

The causes of knee injuries fall broadly into the following categories:

• Tearing or swelling of the tendons, ligaments, or connective tissues of the knee joint.
• Mechanical problems where the knee structures move out of place.
• Medical conditions such as rheumatoid arthritis, gout, and other diseases.
• Accidents, falls, or trauma may cause fractures or torn tendons and ligaments.
• High-activity sports.

Symptoms of Knee Injuries

Depending on the type of knee injury that you have, your symptoms may vary. However, a knee injury can manifest in the form of one or more of the following symptoms:

• Knee pain
• Swelling in the knee joint or surrounding area
• Instability while standing or walking.
• Bruising
• Difficulty walking
• Red or warm knee.
• Difficulty in putting weight on the affected knee.
• Weakness in the knee.
• Numbness of tingling in the knee.
• Popping or clicking sound in the knee, especially when accompanied by swelling.
• Knee buckling.

Knee Injury Treatment Options In Singapore

There are several knee injury treatment Singapore options available, which are discussed below:

Medications

Depending on the underlying condition that is causing your knee pain, your doctor may prescribe medicines to relieve the pain or swelling. Moreover, if the knee pain is being caused by a disease such as gout or rheumatoid arthritis, the doctor may prescribe its relevant prescription medicine. 

Physical Therapy

Physical therapy is an effective way to strengthen the muscles around your knee and provide it more stability. Your doctor may prescribe physical therapy or other strengthening exercises to improve your flexibility, knee strength, and balance. 

Injections

Sometimes, your doctor may prescribe certain injections that are administered directly into the knee joint to reduce pain and inflammation. These injections could include corticosteroids, hyaluronic acid, and platelet-rich plasma injections.

Knee Surgery

In case of a severe injury to the knee, the only resort might be to have knee surgery. A knee surgery in Singapore may involve any of the following surgical procedures:

Arthroscopic Surgery

In some types of knee injuries, your doctor may be able to operate on the knee joint through an arthroscopic procedure. In such a surgery, the doctor inserts a tiny fibre-optic camera through a small incision and uses thin surgical instruments to operate on the knee through tiny incisions. Through such an arthroscopic knee surgery, the surgeon may be able to remove loose structures from the knee joint or repair and reconstruct damaged tendons and cartilage.

Partial Knee Replacement

In a partial knee replacement surgery in Singapore, the surgeon replaces part of the damaged portions of the knee with replacements made from metal or plastic. Since only part of the damaged bodies are replaced, the surgery is usually performed by making small incisions, reducing recovery time.

Total Knee Replacement

In total knee replacement surgery, the surgeon replaces the damaged part of the bone and cartilage by cutting it away from the thigh bone, shin bone, and knee cap. The cut-away portion is then replaced by an artificial joint made of metal, plastic, and polymers. This is a major surgery that requires a longer recovery time and is more painful.

Osteotomy

Osteotomy is the surgical procedure that involves the removal of bone from the thigh bone or shin bone in order to align the knee joint properly. This procedure is usually performed to delay or avoid total knee replacement surgery. 

Home Remedies for Knee Injuries

Although seeking effective knee pain treatment from a specialist orthopaedic doctor in Singapore is crucial to ensure that you start your knee pain treatment properly, there are specific home remedies that may help to provide some knee pain relief. These include:

• Taking rest from your daily activities and not putting much strain on the knee joint may help with the pain and inflammation. 
• Applying ice on the affected knee joint may help reduce swelling, whereas applying heat on the affected knee after the initial swelling has subsided may help with the pain.
• Wrapping the affected knee in a lightweight and breathable compression bandage can help prevent fluid buildup in the joint and maintain stability in the knee.
• Taking over-the-counter pain and anti-inflammatory medicines as advised by the doctor.

Alternative Medicine

Sometimes, alternative medicine such as acupuncture and chiropractic adjustments may help with reducing pain in the knee joint. 

How To Prevent Knee Injuries

Below are some tips to prevent knee injuries:

• Maintain a healthy weight to reduce the risk of knee injuries and osteoarthritis.
• Always wear supportive shoes to maintain proper balance.
• Strengthen your knees by doing muscle-strengthening exercises and stretches.
• Always warm up before exercising or playing any sport by doing stretches and light exercises.
• Similarly, cool down by doing light stretches after engaging in a sports activity or exercise.
• Avoid sudden turning or twisting movements of the knees, especially while running, jumping, or playing sports.
• Consider physical therapy and exercise to manage your pain and not worsen the condition.

How Do I Know If My Knee Injury Is Serious?

Consider visiting your doctor if you experience the following symptoms associated with knee injuries:

• Redness
• Highly visible swelling
• Warmth
• Pain that affects your daily routine and/or your sleep
• Fever

If your knee pain and other symptoms persist for more than two months, it is time to seek medical attention.

How Long Do Knee Injuries Take to Heal?

The knee injury recovery time comes down to both the severity and your dedication to aftercare. In case of minor pain, simply spending a day or two off your feet may be all that is necessary. If the pain remains after two days, it is time to check with a specialist.

If you have a minor soft tissue injury, you might be looking at a couple of months of rehabilitation while severe injuries can take up to a full year to heal.

In case of knee surgery, most knee surgeries require one to two months for full rehabilitation. While you will be back on your feet fairly quickly, bear in mind that full recovery takes six months to one year.  In most cases, full maturation after cartilage and ligament procedures can take over a year. It is normal to feel knee joint stiffness after surgery, which should last 6 to 8 weeks. This is due to tight soft tissues and weak muscles around the knee. Regularly attending physio sessions can help prevent prolonged stiffness.

The key factor in successful and speedy recovery is closely following the post-op protocol. Always sticking to your knee injury doctor’s recommendations ensures that you regain strength and mobility safely and that you are working toward the unique requirements based on your specific health history and lifestyle.

What Are Some Exercises to Strengthen Your Knee?

Strength and flexibility create the foundation of healthy knees. To prevent injuries, it’s important to stay active.

Start by focusing on strength. A simple warm-up will go a long way in preventing injuries and muscle cramps. When your muscles are tight, your joint is constricted and more likely to get hurt. Likewise, cooling down after exercise is a smart way to prevent soreness and keep your muscles elastic. Getting into the habit of regular daily stretching is one of the best things you can do for your long-term health.

Once you’re stretched and ready, it’s time to focus on building muscles. The quadriceps, hamstrings, and calves create the support and they’ll be there to prevent injury. Do take care to follow the exercise steps correctly to prevent ankle injuries or rotator cuff tears. Your gluteal muscles, quadriceps, and hamstring are also important in keeping your knees agile and injury-free. Every part of your body is connected to another so full-body fitness is the long-term key. That said, there are three key workouts that you’ll want to make part of your routine. Alternatively, running is also a good option to improve bone density in your knees.

Frequently Asked Questions Regarding Knee Injuries

What Lifestyle Changes May Help Avoid Chances of Re-injury In the Future?

Changing lifestyle and some of its ways can significantly impact the healing time of a knee injury and consecutively pain caused by it. We have mentioned some of these for your idea.

• Weight Management: Knees can deform and lose mobility due to excess body weight. Shedding off the excess pounds can improve the range of motion. Maintaining a regular exercise routine and eating a balanced diet and well-proportioned meals can help reduce weight.
• Strength Exercises: If your physical activity is next to zero, then your knee joints will be weak. By practising strength-training, you can work on your core muscles, quads and hamstrings. These in turn provide extra support around the knee joint. This reduces the chances of knee meniscus injury, knee tendon injury and knee injury after a fall. Exercises such as deadlifts with squats and maintaining planned positions can strengthen body muscles.
• Improve flexibility and mobility:10 minutes of stretching every day enhances the range of motion of knees. For strength and balance, light yoga should be practised regularly. Tai-chi is also a good option for improving knee joint coordination and is adopted by many. 
• Use proper form when exercising: Whether you’re walking, running, weightlifting or doing knee-intensive sports, using proper form minimises stress on your knees. Consider working with a trainer or physical therapist to ensure good form.
• Wear supportive shoes: Shoes with good cushioning and arch support help reduce impact on your knees when you’re active. Replace shoes regularly.
• Listen to your body: If certain activities cause pain, avoid doing them. Rest your knees when they feel painful or overworked.
• Use knee pads or braces: These can help stabilise and support your knees during activities that put extra pressure on them.
• Don’t ignore pain: See a specialist if you have chronic or worsening pain. Early treatment can prevent further damage.

When Should I Consider Knee Replacement Surgery?

Knee replacement surgery may be an option for severe, debilitating pain that doesn’t respond to more conservative treatments. While it is an invasive treatment, total knee replacements reliably improve the quality of life. If you are slowed down by severe pain even after following routine medication, injections, therapy, braces, and lifestyle modifications, you may be a good candidate for surgery.

Should You Exercise with a Knee Injury?

While working out is probably the last thing you feel like doing with a knee injury, it is also the most useful thing you can do. However, always follow your doctor’s or physical therapist’s advice before doing any exercise after a knee injury. According to research from Harvard Medical School, exercising is an effective measure that you can do for both the short-term and long-term health of your knee.

There are exceptions to the rules though. It’s crucial to avoid workouts if you are experiencing any of the following:

• Fever
• Pain that is not improving with time
• Pain that gets worse with activity
• Pain that wakes you up at night

How Long Does It Take To Recover From A Knee Injury?
