Arthroscopic Treatment of Osteochondritis Dissecans (OCD) of the Shoulder is a specialized technique that uses instruments of Dr. Chudik’s own design to evaluate and treat OCD lesions of the humeral head through small arthroscopic incisions. The procedure addresses focal disruption of the subchondral bone and overlying cartilage, preserving the joint surface in stable lesions and replacing it in displaced cases. Dr. Chudik’s specialized instruments support the precise small-incision approach this uncommon shoulder condition requires.
What Is Arthroscopic Shoulder OCD Treatment?
Osteochondritis dissecans (OCD) is a localized injury or condition affecting the bone just below the cartilage surface of a joint. OCD is often associated with repetitive trauma and sports. In OCD, the bone just below the joint surface fails and fractures from repetitive stress or from interruption of its local blood supply. The overlying cartilage, no longer properly supported by the affected bone, can separate and an OCD fragment of bone and cartilage can break loose.
If the OCD is stable (not loose) and the patient is still growing, conservative treatment with rest can sometimes allow it to heal. When the OCD lesion is more mature and has separated from the rest of the bone (with the overlying cartilage either intact, partially separated, or completely separated as a loose body), surgery is often needed to stimulate, graft, stabilize, or remove the OCD fragment.
If neglected, an OCD fragment may come loose, catch in the joint (causing pain, locking, clicking), and leave a hole in the joint surface that accelerates wear and arthritis of the shoulder joint.
Dr. Chudik developed specialized instruments that allow OCD lesions to be evaluated and treated through small arthroscopic incisions.
Development Rationale
OCD lesions can vary widely in size, location, stability, and stage. Treatment selection depends on these factors and may involve drilling, fixation, grafting, or fragment removal. Conventional open approaches to OCD lesions require larger incisions and more soft-tissue disruption, which is particularly limiting for the joint preservation approach OCD treatment requires.
Dr. Chudik developed specialized instruments to:
- Access OCD lesions through small arthroscopic portals
- Evaluate lesion stability and size with precision
- Treat lesions with the appropriate technique (drilling, fixation, grafting, or removal) without converting to open surgery
- Smooth or stabilize unstable cartilage flaps
- Stimulate biologic healing in the bone bed
The specialized instruments support a joint-preserving approach to a condition where preserving as much native cartilage as possible matters for long-term outcomes.
Who Is a Candidate?
Candidates typically have:
- Symptomatic OCD of the humeral head documented on MRI
- Mature lesions that have separated from the surrounding bone
- Mechanical symptoms (catching, locking) suggesting an unstable or loose fragment
- Failure of non-surgical treatment in skeletally immature patients with stable lesions
- Functional limitation in active patients
Stable lesions in skeletally immature patients are typically treated non-surgically with rest for six to 12 months before surgery is considered.
Contraindications include shoulder infection, inability or unwillingness to complete the postoperative program of activity limitation and rehabilitation.
How the Procedure Is Performed
The procedure is performed as outpatient surgery under general anesthesia with an interscalene nerve block. Dr. Chudik uses arthroscopic visualization through small portals plus the specialized instruments he designed for OCD treatment.
After diagnostic arthroscopy identifies the OCD lesion, the lesion is probed and evaluated for stability, depth, size, and condition of the overlying cartilage. Treatment is selected based on these factors:
- Stable lesions: drilling through the subchondral bone to stimulate revascularization and healing
- Unstable but in-situ fragments: fixation with bioabsorbable implants or metal fixation that compresses the fragment back to its native bed
- Displaced fragments that are salvageable: reattachment to the prepared bone bed
- Displaced fragments that are not salvageable: removal of the loose body, smoothing of any rough edges or unstable cartilage flaps in the bone bed, and stimulation to fill in with reparative tissue
The specialized instruments support precise lesion evaluation and the appropriate treatment selection. Dr. Chudik discusses options with each patient and helps determine the best treatment for the specific lesion characteristics.
Recovery and Rehabilitation
Recovery follows a protected protocol:
- Sling for up to six weeks
- Return to school or sedentary work in less than one week
- Physical therapy to restore motion and strength for up to four to six months
After the shoulder is fully rehabilitated, Dr. Chudik’s Shoulder Functional Capacity Evaluation confirms rehabilitation is complete and the patient can safely return to activities.
Return to gentle daily activities is typical at six to eight weeks after surgery. Return to sport is typically four to six months after surgery, depending on the specific procedure performed and the demands of the sport and position.
Risks and Outcomes
Specific surgical risks include:
- Wound infection
- Bleeding or injury to blood vessels
- Injury to nerves (numbness, weakness)
- Non-union or non-healing of the OCD fragment in repair situations
- Shoulder stiffness
- Arthritis
Outcomes for the arthroscopic technique are best when the lesion is identified and treated early, before significant cartilage damage develops. Stable lesions in skeletally immature patients have the highest healing potential. Adult OCD and chronic displaced lesions have less predictable outcomes.
Why Dr. Chudik for Arthroscopic Shoulder OCD Treatment
Dr. Chudik developed specialized instruments for the arthroscopic evaluation and treatment of OCD lesions of the shoulder. The condition is uncommon, and most orthopaedic surgeons see relatively few cases. Dr. Chudik’s instrument design and clinical experience across the spectrum of OCD presentations support the appropriate treatment selection (drilling, fixation, grafting, or fragment removal) for each individual lesion.
