What is elbow arthroscopy?

Elbow arthroscopy is a minimally invasive procedure that uses a small camera inserted through tiny incisions around the elbow to diagnose and treat conditions including loose bodies, osteochondritis dissecans, elbow stiffness, and synovitis. General anesthesia is used because the elbow's confined anatomy and proximity to critical nerves require precise positioning and complete muscle relaxation.

Why this approach — at MOS

Elbow arthroscopy is among the most technically demanding arthroscopic procedures because of the nerve proximity and limited working space within the joint. At Maryland Orthopedic Specialists, Dr. Fitzgibbons approaches every elbow arthroscopy with careful pre-operative planning, including elbow CT scan when loose bodies are present — to count, locate, and characterize all fragments before the procedure. A missed loose body that is not retrieved leaves the patient with ongoing mechanical symptoms.

For young athletes with OCD of the capitellum — a condition particularly common in young baseball players, gymnasts, and racquet sport athletes — the treatment decision (drilling vs. fragment removal vs. fixation) depends on the stability of the OCD lesion on MRI. Stable lesions with an intact cartilage cap are managed with activity restriction; unstable lesions require surgical intervention to prevent the fragment from separating into the joint as a loose body. Serving the Montgomery County youth athlete population means Dr. Fitzgibbons sees a regular volume of these cases.

Concurrent ulnar nerve management is planned when elbow arthroscopy is performed alongside UCL reconstruction. The nerve is not universally transposed at the time of arthroscopy alone, but its course is confirmed and documented.

Who is a candidate?

Indications

Elbow loose bodies causing locking, catching, or limited range of motion
Osteochondritis dissecans (OCD) of the capitellum in young athletes — loose fragment removal, drilling, or fixation
Elbow contracture (stiffness limiting extension or flexion) unresponsive to therapy
Synovitis or intra-articular inflammation causing pain and swelling despite conservative treatment
Evaluation of intra-articular pathology concurrent with UCL reconstruction or other elbow surgery
Posterior elbow impingement in throwing athletes (olecranon osteophytes causing terminal extension pain)
Plica resection (removal of inflamed synovial folds)

Contraindications

Severe post-traumatic elbow arthritis with extensive bone loss — arthroscopy offers limited benefit in this setting
Significant prior elbow surgery or trauma causing distorted anatomy that increases portal placement risk
Active elbow infection
Patients with anatomic variations placing major nerves at unusual risk — require careful pre-operative planning

Conservative Treatment First

Most elbow conditions that are ultimately treated with arthroscopy begin with conservative management. Elbow stiffness is addressed with a supervised stretching and splinting program using static progressive or dynamic splinting. Synovitis and inflammatory conditions are managed with NSAIDs, corticosteroid injection, and activity modification. OCD lesions in young patients with stable cartilage caps are managed with activity restriction and observation, with surgery reserved for unstable lesions or those that fail to heal.

Loose bodies are the most common purely mechanical indication for elbow arthroscopy, and conservative treatment is generally not effective for symptomatic loose bodies that are causing intermittent locking — these are best addressed surgically. For all other indications, an adequate trial of 3–6 months of conservative management before arthroscopy is appropriate.

The procedure

What Is Elbow Arthroscopy?

The elbow is a complex hinge joint formed by three bones — the humerus (upper arm), radius (forearm, thumb side), and ulna (forearm, small finger side). It allows both flexion-extension and the forearm rotation (pronation and supination) that occurs at the radiocapitellar and radioulnar joints. Several major neurovascular structures pass directly around the elbow: the ulnar nerve at the medial (inner) side, the radial nerve at the anterior (front), and the brachial artery in the antecubital fossa. This anatomic density makes elbow arthroscopy technically demanding compared to shoulder or knee arthroscopy — portal placement must be precise to avoid nerve injury.

Common indications for elbow arthroscopy include loose bodies (fragments of cartilage or bone floating in the joint that cause locking and catching), osteochondritis dissecans (OCD) of the capitellum (common in young throwers and gymnasts), contracture release for elbow stiffness, synovitis debridement, and radial head pathology. It is also used to evaluate the elbow joint in UCL reconstruction candidates and to address intra-articular pathology at the time of UCL surgery.

What Happens During Elbow Arthroscopy?

Setting and anesthesia: Performed at an ambulatory surgery center under general anesthesia. General anesthesia — rather than regional block alone — is used because complete muscle relaxation is important for safe distraction of the elbow joint and precise portal placement in proximity to major nerves. The procedure takes 30–60 minutes.

Positioning: The patient is positioned prone (face down) with the arm suspended, or lateral decubitus with the arm over a bolster, allowing gravity to distract the elbow and providing access to both anterior and posterior compartments. Each surgeon has a preferred position — Dr. Fitzgibbons uses the approach that provides the most consistent access to all compartments in his hands.

Portal placement: Portals are established in a systematic sequence, starting with the posterolateral portal for initial joint distension with saline. The standard portals include: anterolateral (for viewing the anterior compartment, capitellum, radial head), anteromedial (for working instruments in the anterior compartment), and posterior portals for the posterior compartment and olecranon. Each portal is created with meticulous care given the proximity of the ulnar nerve (immediately behind the medial epicondyle) and the radial nerve (in the anterior compartment lateral to the brachialis).

Surgical procedures: Loose bodies are identified and removed with arthroscopic graspers. OCD lesions are drilled (to stimulate healing for stable lesions) or the unstable fragment is removed and the crater is drilled or treated with microfracture. Contracture release involves releasing the anterior capsule (for flexion deficit) or posterior capsule and olecranon fossa débridement (for extension deficit). Synovial tissue is resected with a motorized shaver. Olecranon osteophytes are removed with an arthroscopic burr.

A soft dressing is applied and the arm placed in a padded posterior splint.

Recovery timeline

Days 1–5

Soft dressing and splint. Gentle elbow motion encouraged. Ice and elevation control swelling.

Week 1–2

Dressing reduced, sutures removed. Light elbow range-of-motion exercises. Sling discontinued as comfort allows.

Weeks 2–6

Return to light activities. Progressive strengthening. Office and desk work typically possible by week 3–4.

Months 2–3

Full recovery for most procedures. Contracture release cases may continue PT through 4–6 months to maintain motion gains.

Recovery from elbow arthroscopy is generally faster than from open elbow surgery. Portal sites heal quickly, and the joint recovers motion faster without the scar tissue of a larger incision. Elbow stiffness is the most common post-operative challenge and responds to active assisted range-of-motion exercises begun early.

For contracture release patients, early motion is critical — the motion gained during surgery must be maintained by aggressive therapy and splinting, otherwise the released capsule scars down and the contracture recurs. Physical therapy beginning by day 3–5 post-operatively is essential for contracture release patients. MOS coordinates therapy for all elbow arthroscopy patients.

Frequently Asked Questions

Why does elbow arthroscopy require general anesthesia when other joint arthroscopies can be done under regional block?

The elbow's confined anatomy places the ulnar nerve, radial nerve, and brachial artery in very close proximity to the arthroscopic portals. Complete muscle relaxation from general anesthesia allows the joint to be distended and the portals placed with maximum precision. A regional nerve block alone may not produce the muscle relaxation needed for safe portal placement, and a partially sedated patient who moves during a critical moment in the procedure creates unnecessary risk.

What are elbow loose bodies and where do they come from?

Loose bodies are fragments of cartilage or bone that break off from the joint surface and float freely within the elbow joint. They cause intermittent locking, catching, and pain. They can come from osteochondritis dissecans, elbow arthritis, direct trauma (osteochondral fracture), or primary synovial osteochondromatosis (a condition where the joint lining produces multiple bony fragments). Arthroscopic removal eliminates the locking and typically resolves the mechanical symptoms promptly.

Can elbow arthroscopy cure elbow stiffness permanently?

Arthroscopic contracture release can significantly improve elbow range of motion — particularly for loss of extension (inability to straighten the arm). However, the results depend on aggressive post-operative physical therapy and splinting. Without diligent rehabilitation, the released capsule can scar down and the stiffness recurs. When therapy is followed properly, motion improvements are typically durable. Complete restoration of normal range is not always achievable in chronic or post-traumatic stiffness.

What is osteochondritis dissecans (OCD) of the elbow?

OCD is a condition in which a segment of cartilage and the bone beneath it loses its blood supply and separates from the underlying bone. In the elbow, it most commonly affects the capitellum (the rounded end of the humerus). It is particularly common in young overhead athletes — baseball pitchers, gymnasts — and is related to compressive forces at the radiocapitellar joint. Stable OCD lesions with an intact cartilage cap are managed with rest. Unstable lesions or loose fragments require arthroscopic removal or fixation.

How long until an athlete can return to throwing after elbow arthroscopy?

For simple loose body removal or OCD drilling, athletes typically return to throwing activities at 6–8 weeks and competitive throwing at 3–4 months. Contracture release cases require longer therapy before sport return. For young athletes undergoing OCD treatment, return to sport depends on healing confirmation by MRI or CT scan, which may take 3–6 months.
