Knee Injuries & Knee Pain Treatments

Pauline Ong

REVIEW:
I had medial meniscus tear with osteoarthritis 4 months ago. The doctor suggested surgery but I wanted to try the non-surgical methods first. I was thus introduced to PhysioActive. I have undergone treatment with ultrasound and shockwave therapy, as well as incorporated exercises to strengthen my core muscles, quadriceps and hamstring and not forgetting functional exercises. I am now almost 100% pain-free. Thank u so much!

Knee injuries are among the most common causes of pain and mobility problems seen in physiotherapy clinics across Singapore. Whether caused by sports, overuse, or everyday strain, the knee is a complex joint that bears a heavy load in every step we take. At PhysioActive, our goal is to help patients regain movement, reduce pain, and restore confidence through targeted, evidence-based rehabilitation.


Understanding the Knee Joint

The knee functions as a hinge joint connecting the thigh bone (femur), shin bone (tibia), and kneecap (patella). It depends on four key ligaments — the ACL, PCL, MCL and LCL — along with cartilage, tendons, and surrounding muscles for stability and smooth motion.

Common Knee Injuries

ACL Tear

A tear in the anterior cruciate ligament (ACL) often occurs during sudden stops, twists or pivots common in sports such as football or basketball. Patients may feel a “pop” followed by swelling and instability. Physiotherapy focuses on strengthening and neuromuscular control to restore knee stability and confidence, both before and after surgery [1].

MCL and LCL Injuries

The medial (MCL) and lateral (LCL) collateral ligaments support the sides of the knee. Injuries usually happen with sideways impact or awkward landings. Rehabilitation typically involves pain management, bracing when needed, and progressive strengthening to return to full mobility [2].

Meniscus Tears

The meniscus acts as a shock absorber between the thigh and shin bones. Twisting injuries or age-related wear can lead to tears, causing pain, clicking, or knee locking. Physiotherapy combines joint mobilisation, manual therapy, and strengthening to improve joint motion and stability.

Patellar Tendonitis (Jumper’s Knee)

Repetitive stress on the patellar tendon — often from running, jumping or hiking — can lead to inflammation and pain below the kneecap. Treatment includes load management, shockwave therapy, and eccentric strengthening exercises to promote healing [3].

Degenerative or Overuse Conditions

Chronic conditions such as osteoarthritis, patellofemoral pain, and iliotibial band friction syndrome are increasingly common among active adults.
Our physiotherapists use exercise therapy, mobility work, and lifestyle strategies to relieve pain and delay progression of joint wear.

Causes and Risk Factors

Knee injuries can occur in anyone, but some situations make them more likely:

  • Sports with sudden direction changes or jumping
  • Repetitive overuse in running or cycling
  • Muscle imbalance between quadriceps and hamstrings
  • Age-related cartilage degeneration
  • Incomplete recovery from previous injuries

In Singapore’s humid conditions, slippery sports courts and improper footwear are frequent contributors to knee sprains and strains, especially among recreational athletes.


Diagnosis and Assessment

Our physiotherapists conduct a detailed evaluation to determine the source of your pain and the structures affected. Assessment may include:

  • Posture and gait analysis
  • Range of motion and muscle strength testing
  • Ligament and stability tests
  • Functional movement screening

If structural damage such as a ligament or meniscus tear is suspected, imaging such as an MRI or X-ray may be recommended for confirmation.


Treatment and Rehabilitation

At PhysioActive, every treatment plan is tailored to the patient’s specific diagnosis, activity level, and recovery goals. Our approach prioritises non-surgical rehabilitation whenever possible.

Physiotherapy and Manual Therapy

Manual therapy and joint mobilisation help reduce stiffness and restore movement. Techniques may include soft tissue release and trigger point therapy to relieve tension and improve circulation.

Exercise Therapy

Progressive strengthening of the quadriceps, hamstrings, glutes and core supports long-term stability. Programmes are adapted to each phase of recovery — from pain management to sport readiness.

Shockwave and Ultrasound Therapy

For tendon and soft tissue injuries such as patellar tendonitis or chronic ligament pain, adjunct therapies like shockwave therapy and ultrasound may be used to stimulate tissue healing [4].

Functional and Neuromuscular Training

Once pain and swelling subside, functional retraining helps re-educate balance, coordination, and movement control to prevent re-injury.

Post-Surgical Rehabilitation

When surgery is required (such as ACL or meniscus repair), rehabilitation via physiotherapy plays an essential role in restoring strength, mobility, and function.


Rehabilitation Timeline

Recovery depends on the severity and type of injury:

  • Mild sprains or strains: 2–6 weeks
  • Moderate tendon or meniscus injuries: 6–12 weeks
  • Post-ACL reconstruction: 6–9 months before full return to sport

Your physiotherapist will adjust your programme according to progress, ensuring safe recovery and long-term results [5].


Prevention and Long-Term Knee Health

Prevention is the most effective way to maintain strong, pain-free knees:

  • Warm up and cool down before and after activity
  • Strengthen key muscle groups regularly
  • Maintain flexibility through stretching and mobility work
  • Avoid sudden increases in training load
  • Replace worn footwear
  • Address early pain before it worsens

Patient Success Story

Overcoming Meniscus Tear Without Surgery

When Pauline Ong was diagnosed with a medial meniscus tear and osteoarthritis, she wanted to avoid surgery and explore non-surgical options.

“I had medial meniscus tear with osteoarthritis 4 months ago. The doctor suggested surgery but I wanted to try the non-surgical methods first. I was thus introduced to PhysioActive.”

Her treatment combined ultrasound therapy, shockwave therapy, and a series of strengthening and functional exercises for her core, quadriceps, and hamstrings. With consistent sessions and guided rehabilitation, she achieved remarkable improvement.

“I have undergone treatment with ultrasound and shockwave therapy, as well as incorporated exercises to strengthen my core muscles, quadriceps and hamstring and not forgetting functional exercises. I am now almost 100% pain-free. Thank u so much!”Pauline now moves comfortably in her daily life, demonstrating the effectiveness of targeted physiotherapy and patient commitment.

Frequently Asked Questions

Can knee injuries heal without surgery?

Many mild to moderate ligament sprains, tendon issues, and meniscus injuries respond well to physiotherapy. Our treatment approach focuses on restoring joint stability, strength, and mobility to support recovery without surgical intervention whenever possible.

What can I expect during my first physiotherapy session?

Your first session involves a detailed assessment of knee movement, strength, and alignment. The physiotherapist will explain the diagnosis, design a tailored treatment plan, and begin pain relief techniques or gentle exercises if appropriate.

How long does rehabilitation take?

Recovery depends on injury type and severity. Mild sprains may improve within a few weeks, while more complex injuries like ACL or meniscus tears can take several months. Consistency with exercises and guided therapy is key to lasting recovery.

When should I seek help for knee pain?

You should seek help if your knee pain causes swelling, instability, locking, or limits daily activities. Early intervention prevents further injury and improves long-term outcomes. Our physiotherapists at PhysioActive can assess your condition and guide your recovery.

What can I do to prevent knee injuries in the future?

Regular strength training for the quadriceps, hamstrings, and glutes helps protect the knee. Combine this with mobility exercises, proper warm-ups, and gradual progression in activity levels to reduce your risk.
