What is an arthroscopy?

‍

Arthroscopy is a minimally invasive surgical procedure that allows doctors to visualize, diagnose, and treat problems within a joint. It is commonly performed on joints such as the knee, shoulder, hip, ankle, and wrist. During an arthroscopic procedure, a small, pencil-sized instrument called an arthroscope is inserted through small incisions in the skin, muscle, and joint capsule to visualize the interior of the joint by means of a camera, allowing the surgeon to examine the joint and perform necessary treatments.

‍

The arthroscope contains a light source and a small camera that transmits images of the joint to a video monitor. This provides a clear view of the joint structures, including the cartilage, ligaments, tendons, and synovium (the lining of the joint). The surgeon can assess the condition of these structures and identify any abnormalities or injuries.

‍

Arthroscopy can be both diagnostic and therapeutic. In a diagnostic arthroscopy, the surgeon examines the joint to identify the cause of symptoms such as pain, swelling, or instability. Based on the findings, further treatment options can be determined. In a therapeutic arthroscopy, the surgeon can perform various procedures to treat specific joint conditions, such as repairing damaged cartilage, removing loose fragments or inflamed tissue, or reconstructing ligaments.

‍

Who can benefit from an arthroscopy?

‍

Arthroscopy can benefit a wide range of individuals who have joint problems or injuries. Some common conditions that can benefit from arthroscopic surgery include:

‍

1. Knee problems: Arthroscopy is commonly performed on the knee joint and can be used to diagnose and treat various knee conditions, including meniscus tears, ligament injuries (such as ACL tears), cartilage damage, patellar (kneecap) problems, and synovitis (inflammation of the joint lining).
2. Shoulder problems: Arthroscopy is often used for shoulder issues such as rotator cuff tears, labral tears (such as Bankart or SLAP tears), shoulder impingement syndrome, recurrent shoulder dislocations, and inflammation or damage to the joint lining (synovitis).
3. Hip problems: Arthroscopy can be beneficial for certain hip conditions, including labral tears, hip impingement (femoroacetabular impingement), removal of loose bodies or fragments, and synovitis.
4. Ankle problems: Arthroscopy can be used to diagnose and treat various ankle conditions, such as cartilage damage, loose bodies, impingement syndromes, and ankle instability.
5. Wrist problems: Arthroscopy can help evaluate and treat wrist conditions, including ligament tears (such as TFCC tears), cartilage injuries, ganglion cysts, and chronic wrist pain.
6. Elbow problems: Arthroscopy can be used to assess and address conditions like tennis elbow (lateral epicondylitis), golfer's elbow (medial epicondylitis), loose bodies, and elbow stiffness.
7. Other joints: Arthroscopy can also be performed on other joints, although less commonly, such as the hip, ankle, and temporomandibular joint (TMJ).

‍

The suitability of arthroscopy for an individual will depend on several factors, including the specific joint involved, the nature and severity of the condition or injury, the individual's overall health, and the recommendation of the healthcare provider. It is important to consult with an orthopedic surgeon or a specialist experienced in arthroscopic procedures to determine if arthroscopy is the appropriate treatment option for your specific joint problem. They will assess your condition, consider alternative treatments, and discuss the potential benefits, risks, and expected outcomes of arthroscopic surgery.

After arthroscopy: What to expect

‍

After undergoing arthroscopy, there are certain expectations for the recovery process. While experiences may vary depending on the specific procedure and individual factors, here are some general aspects you can expect after arthroscopy:

‍

1. Post-operative pain: It is common to experience pain, swelling, and discomfort in the joint following arthroscopy. Your surgeon will prescribe pain medications to help manage the pain during the initial recovery period. Using ice packs and elevating the affected limb can also help reduce swelling and discomfort.
2. Incision care: You will have small incisions where the arthroscope and surgical instruments were inserted. It is important to keep the incision sites clean and dry as per your surgeon's instructions to prevent infection. You may need to change dressings or use sterile strips to support the incisions as they heal.
3. Restricted activities: Your surgeon will provide specific instructions regarding weight-bearing, joint movement, and activity limitations after the arthroscopy. Depending on the procedure, size, severity and location of the joint involved, you may need to use crutches, wear a brace, or immobilize the joint in a splint or cast for a period of time. It is important to follow these instructions carefully to facilitate proper healing.
4. Physical therapy: Physical therapy may be recommended to help restore joint function, strength, and range of motion. The timing and extent of physical therapy will depend on the specific procedure and the recommendations of your healthcare provider. Physical therapists will guide you through exercises and activities aimed at restoring function and optimizing recovery.
5. Recovery timeline: The recovery timeline varies depending on the procedure, the joint involved, and individual factors. In general, you can expect to gradually resume normal activities over a period of weeks to months. Your surgeon will provide guidance on when you can return to work, exercise, and other daily activities.
6. Follow-Up appointments: You will have follow-up appointments with your surgeon to monitor your progress, remove stitches or sutures, and evaluate the healing process. These appointments are an opportunity to address any concerns or complications and ensure that your recovery is progressing as expected.

‍

It is important to note that individual experiences may vary, and your surgeon will provide personalized instructions and advice based on your specific situation. It is essential to communicate any concerns or unexpected symptoms to your healthcare provider during the recovery period. By following their guidance, attending follow-up appointments, and actively participating in rehabilitation, you can optimize your recovery after arthroscopy and promote the best possible outcome for your joint health.

How can physical therapy help? 

‍

Physical therapy plays a crucial role in the recovery process after arthroscopy. Here's how physical therapy can help:

‍

1. Pain management: Physical therapists can use various modalities such as ice, heat, ultrasound, or electrical stimulation to help manage post-operative pain and reduce swelling around the joint.
2. Range of motion exercises: Physical therapists will guide you through a series of exercises aimed at restoring and improving the range of motion in the joint. These exercises may initially include passive or active range of motion exercises, with or without assistance, to prevent muscle stiffness and maintain joint mobility. As the patient improves, treatment will progress to gentle stretching exercises such as; manual or self-stretching as tolerated, and joint mobilizations, to increase muscle flexibility and restore normal joint function.
3. Strengthening exercises: Physical therapists will prescribe strengthening exercises to target the muscles around the affected joint. Initially, low intensity resistance exercises are given and as the joint tolerates, more challenging resistance exercises are prescribed. Strengthening these muscles helps support the joint, improve stability, muscular endurance and performance.  The exercises may involve using resistance bands, weights, or bodyweight exercises, depending on the joint and the specific goals of rehabilitation.
4. Proprioception and balance training: Arthroscopy can temporarily disrupt the normal sensory feedback from the joint. Physical therapists will incorporate exercises to enhance proprioception (awareness of joint position) as well as static and dynamic balance to help you regain confidence and stability in the joint, especially if the lower limbs are affected.
5. Functional training: A final component of an individualized rehabilitation program involves practicing activities that simulate the physical demands of a patient’s work or desired recreational or sport activity. Physical therapists will incorporate functional training. It involves simulation of activities and drills which enable a patient to practice under supervised conditions to receive feedback on correct mechanics. 
6. Gait training: If the arthroscopy procedure involves the lower extremities, physical therapists will prescribe gait training. It can help improve your walking pattern and normalize your gait. They may provide guidance on proper weight-bearing, foot placement, and balance to optimize walking function and reduce any compensatory movements.
7. Education and home exercise program: Physical therapists educate the patients about arthroscopy, its indications, benefits, and the importance of rehabilitation programs in post-operative care. They also teach joint protection strategies, proper body mechanics, and activity modifications to prevent re-injury and promote long-term joint health. They will also create a personalized home exercise program and teach the patients how to incorporate it into their daily routine to reinforce the interventions and for optimal recovery. 
8. Monitoring and progression: Throughout your rehabilitation, physical therapists will closely monitor your progress, adjust your treatment plan as needed, and provide ongoing guidance. They will work in collaboration with your surgeon and healthcare team to ensure a coordinated approach and to address any complications or concerns that may arise.

‍

Physical therapy after arthroscopy is typically started soon after the procedure and continues for several weeks or months, depending on the individual and the specific procedure. The frequency and duration of therapy sessions will depend on the recommendations of your healthcare provider. It is important to actively participate in your therapy sessions, follow the guidance of your physical therapist, and adhere to your home exercise program to optimize your recovery, regain function, and achieve the best possible outcome after arthroscopy.
