Arthroscopy

Knee Arthroscopy

Knee arthroscopy is a minimally invasive surgical procedure used to diagnose and treat problems within the knee joint. During the procedure, the surgeon inserts a small camera (arthroscope) into the knee, allowing a clear view of the structures inside the joint. This enables the surgeon to examine, diagnose, and treat a variety of knee issues such as:

  • Torn meniscus
  • Damaged articular cartilage
  • Ligament injuries (e.g., ACL, PCL)
  • Loose bone or cartilage fragments
  • Inflammation of the knee joint lining (synovitis)
  • Patella (kneecap) problems
  • Removal of cysts or scar tissue

Arthroscopy can also be referred to as keyhole surgery

Arthroscopy is performed by making a small incision in the skin through which the surgeon inserts an arthroscope — a slender, pencil-sized instrument equipped with a light source and a small lens that transmits real-time images to a TV monitor. This advanced visualization enables the surgeon to clearly assess and diagnose problems within the knee joint. Additionally, specialized surgical instruments can be passed through the arthroscope to repair damage, remove or trim torn tissues or ligaments, and even take small biopsies if necessary.

Arthroscopy is most commonly performed for knee-related problems and is often the preferred diagnostic and treatment method because it provides a more accurate assessment than other techniques such as X-rays, magnetic resonance imaging (MRI) scans, computed tomography (CT) scans, or physical examinations alone.

Physiotherapy before a knee arthroscopy

Prior to your arthroscopic knee surgery, acephysiosports.com will provide you with a tailored exercise programme designed to strengthen the muscles in and around your knee. This preparation helps improve surgical outcomes and supports smoother rehabilitation afterward. The exercises will primarily focus on strengthening your quadriceps and hamstrings to enhance knee stability and function.

Symptoms post arthroscopy

Immediately after the surgery, you will need to rest until the anaesthetic wears off. Due to the effects of the anaesthesia, you may experience numbness, and it may take several hours before full sensation returns to your knee. As the anaesthesia wears off, you may begin to feel mild pain and discomfort around the knee, for which pain relief will be provided. Some stiffness and slight swelling are also common following arthroscopy.

Arthroscopy is typically performed as a day case procedure, meaning you can usually return home the same day if no complications occur. Most patients experience minimal pain and a relatively quick recovery. Walking aids are generally not required unless significant pain or complications arise. Driving should be avoided immediately after the procedure, but you may safely return to driving within 2 to 5 days, provided there are no complications and your knee is pain free.

Physiotherapy treatment post arthroscopy

Immediately after your arthroscopy, physiotherapy treatment from acephysiosports.com will focus on reducing pain and swelling in your knee. Rest, ice, compression, and elevation (RICE) are advised in the initial phase after surgery to help minimise discomfort and inflammation. Physiotherapy treatment during this stage will also aim to help you begin weight bearing and regaining mobility as soon as possible. Early exercises such as quadriceps strengthening and gentle stretching will be prescribed to support knee recovery and rebuild strength.

Although pain is usually minimal after surgery, it may take several weeks for your knee to fully recover. When you have been discharged from the hospital, acephysiosports.com will provide you with a tailored physiotherapy rehabilitation programme focused on helping you recover quickly and return to your normal daily activities or sports. In most cases, you may be able to resume everyday tasks and work within a week of surgery, depending on the physical demands of your job. Returning to sports may take between 1 to 4 weeks, depending on your individual healing and progress.

Physiotherapy following knee arthroscopy includes:

  • Pain management techniques such as ice therapy and gentle massage
  • Swelling reduction through compression, elevation, and controlled movement
  • Range of motion exercises to restore knee flexibility
  • Strengthening exercises for the quadriceps, hamstrings, and surrounding muscles
  • Balance and proprioception training to improve joint stability
  • Gait re-education to ensure proper walking patterns
  • Gradual progression to functional and sport-specific exercises as recovery advances

In the later stages of your rehabilitation activities may include:

  • Advanced strengthening exercises using resistance bands or weights
  • Balance and coordination drills to enhance knee stability
  • Low-impact cardiovascular exercises such as cycling or swimming
  • Functional movement training, including squats, lunges, and step-ups
  • Sport-specific drills to prepare for a safe return to activity
  • Agility and plyometric exercises to restore power and confidence
  • Stretching routines to maintain flexibility and prevent stiffness

The success of your recovery and rehabilitation programme largely depends on the severity of your initial knee problem and your commitment to following the prescribed physiotherapy plan. Consistent participation in exercises, attending scheduled sessions, and adhering to your physiotherapist’s advice will greatly enhance your recovery, helping you regain full function and return to your normal activities more effectively.
