Knee Arthroscopy & Sports Injury

Knee pain after a sports injury can affect your daily life, fitness routine, and overall mobility. Whether you're a professional athlete, a fitness enthusiast, or someone who enjoys recreational sports, timely diagnosis and treatment are essential for a quick recovery. Knee arthroscopy is one of the most advanced, minimally invasive procedures used to diagnose and treat various knee conditions and sports injuries.

What is Knee Arthroscopy?

Knee arthroscopy is a minimally invasive surgical procedure in which an orthopedic surgeon inserts a small camera (arthroscope) through tiny incisions around the knee. The camera displays high-definition images on a monitor, allowing the surgeon to diagnose and treat knee problems with precision. Compared to traditional open surgery, arthroscopy involves smaller incisions, less pain, reduced blood loss, faster recovery, a lower risk of infection, and a quicker return to sports and daily activities.

Common Knee Sports Injuries

• ACL (Anterior Cruciate Ligament) Tear — common in football, basketball and cricket; signs include a sudden popping sound, severe pain, knee instability and swelling within hours.
• Meniscus Tear — the meniscus acts as a shock absorber; symptoms include locking of the knee, a clicking sensation, pain while twisting and swelling.
• PCL Injury — often after road accidents or direct impact; causes knee pain, swelling and a feeling that the knee may give way.
• Cartilage Damage — from trauma or repeated stress; causes persistent pain, stiffness, a grinding sensation and swelling.
• Patellar Dislocation — the kneecap moves out of position, common in young athletes.
• Loose Bodies Inside the Knee — fragments of cartilage or bone causing locking, pain and reduced mobility, often removed using arthroscopy.

Symptoms That Need Medical Evaluation

Consult an orthopedic specialist if you experience persistent knee pain, swelling after injury, knee instability, locking of the knee, difficulty walking, reduced range of motion, an inability to continue sports, or recurrent knee injuries. Early diagnosis prevents long-term joint damage.

Conditions Treated with Knee Arthroscopy

ACL reconstruction, meniscus repair, meniscus trimming, cartilage repair, loose body removal, synovectomy, PCL injuries, patellar instability, cartilage defects, and early arthritis-related mechanical symptoms.

How is Knee Arthroscopy Performed?

1. Anaesthesia — regional or general anaesthesia is administered.
2. Small incisions — two or three tiny incisions are made around the knee.
3. Arthroscope insertion — a miniature camera is inserted into the joint.
4. Diagnosis — the surgeon examines all structures inside the knee.
5. Treatment — specialized instruments repair or remove damaged tissue.
6. Closure — the incisions are closed with small stitches or adhesive strips.

The surgery usually lasts between 30 and 90 minutes, depending on complexity.

Recovery After Knee Arthroscopy

• First week — pain control, ice therapy, leg elevation, and walking with support if advised.
• 2–6 weeks — physiotherapy begins with range-of-motion and strengthening exercises.
• 6 weeks–6 months — progressive strengthening, sport-specific rehabilitation, and a gradual return to activity.

ACL reconstruction typically requires a longer rehabilitation period than a simple meniscus repair. Physiotherapy is crucial to reduce pain, restore movement, build strength, prevent stiffness and reduce the risk of re-injury.

Can Sports Injuries Be Prevented?

Warm up before exercise, stretch regularly, strengthen leg muscles, maintain proper technique, wear appropriate footwear, avoid overtraining, increase training intensity gradually, stay hydrated, and allow adequate recovery between workouts.
