Percutaneous Tendon & Soft-Tissue Procedures
Image-Guided Treatment for Selected Tendon, Fascial, and Entrapment Conditions in Midtown Manhattan
Chronic tendon and soft-tissue pain does not always improve with rest, medication, activity modification, or rehabilitation alone. In selected cases, an ultrasound-guided percutaneous procedure may be considered to address a specific area of abnormal tendon, a symptomatic calcific deposit, restricted fascial tissue, or a peripheral nerve entrapment.
At Network Spine, these procedures begin with a focused evaluation designed to determine the most likely pain generator. The goal is not simply to perform a procedure on an abnormal-looking structure. It is to determine whether the clinical examination, diagnostic ultrasound, prior imaging, and functional limitations identify a target that may meaningfully change treatment.
What Are Percutaneous Tendon and Soft-Tissue Procedures?
“Percutaneous” means that the treatment is performed through a small skin opening rather than through a conventional surgical incision. Ultrasound guidance allows the physician to visualize the targeted tissue, surrounding anatomy, and procedural instrument in real time.
Depending on the condition, a procedure may involve:
Tendon fenestration or needle tenotomy
Percutaneous ultrasonic tenotomy and debridement
Needling or lavage of a calcific tendon deposit
Selected fascial procedures
Ultrasound-guided nerve hydrodissection
These are not interchangeable treatments. The appropriate procedure depends on whether the primary problem arises from the tendon, fascia, calcific material, peripheral nerve, or another nearby structure.
Conditions That May Be Evaluated
Percutaneous procedures may be considered for selected patients with persistent symptoms involving areas such as:
Rotator cuff tendons
Common extensor or flexor tendons of the elbow
Gluteal tendons
Proximal hamstring tendon
Patellar or quadriceps tendon
Achilles tendon
Plantar fascia
Other accessible tendon or fascial structures
Selected peripheral nerve entrapments
The evaluation places the tendon or soft-tissue finding within the broader regional diagnosis. Rotator cuff tendinopathy may be one component of Shoulder Pain, while common extensor or flexor tendinopathy may contribute to symptoms discussed under Wrist, Hand & Elbow Pain. Gluteal, patellar, Achilles, and plantar fascial conditions may similarly contribute to Hip Pain, Knee Pain, or Foot & Ankle Pain.
Procedures That May Be Considered
Ultrasound-Guided Tendon Fenestration
Tendon fenestration—sometimes called dry needling, needle tenotomy, or percutaneous needle tenotomy—involves repeatedly passing a needle through a targeted region of abnormal tendon under ultrasound guidance.
The procedure may be considered when chronic tendinopathy remains symptomatic despite an appropriate rehabilitation program and other nonoperative treatment. The intent is to create a controlled local response within the targeted tendon rather than simply depositing medication around it.
Fenestration is not appropriate for every tendon abnormality. The location and extent of tendon degeneration, partial tearing, surrounding anatomy, mechanical demands, and rehabilitation history must all be considered.
Percutaneous Ultrasonic Tenotomy and Debridement
Percutaneous ultrasonic tenotomy uses a small instrument introduced through the skin under ultrasound guidance to target and remove selected abnormal tendon or fascial tissue.
The procedure may be considered for selected chronic tendon or fascial conditions that have not responded sufficiently to rehabilitation, load modification, and other appropriate treatments.
Ultrasonic tenotomy is not simply a faster substitute for physical therapy. Patient selection, precise targeting, and the post-procedure loading program remain central to the outcome.
Calcific Deposit Needling and Lavage
Calcific tendinopathy occurs when calcium deposits form within a tendon, most commonly within the rotator cuff. Some deposits are incidental and do not require treatment. Others may contribute to substantial pain, restricted motion, inflammation, or mechanical irritation.
For selected symptomatic deposits, ultrasound-guided needling and lavage—also called barbotage—may be considered. The procedure uses ultrasound to localize the deposit and guide needle placement so that calcific material can be disrupted and, when feasible, withdrawn or irrigated.
The presence of calcium on an X-ray or ultrasound does not by itself establish that the deposit is responsible for the patient’s symptoms. Its size, consistency, location, associated bursitis, examination findings, and clinical history should all be considered.
Ultrasound-Guided Nerve Hydrodissection
Hydrodissection is primarily a peripheral nerve procedure rather than a tendon treatment. It is included here because nerve irritation and restricted nerve movement may sometimes resemble or coexist with tendon and soft-tissue pain.
During hydrodissection, fluid is carefully introduced around a peripheral nerve under ultrasound guidance to separate it from adjacent fascia, scar tissue, muscle, or other surrounding structures. The objective is to improve the tissue plane around the nerve rather than to inject directly into the nerve.
Hydrodissection may be considered in selected entrapment or adhesion-related conditions when the symptoms, physical examination, and ultrasound findings support a peripheral nerve as the likely pain generator.
Patients with burning pain, numbness, tingling, sensitivity, or weakness may also benefit from evaluation for Nerve Pain & Entrapment and review of whether Nerve Blocks may be appropriate.
Why Ultrasound Guidance Matters
Musculoskeletal ultrasound provides real-time visualization of tendons, fascia, bursae, peripheral nerves, blood vessels, and other superficial structures. During a procedure, it also allows continuous visualization of the needle or instrument relative to the intended target.
Ultrasound guidance may help the physician:
Confirm the location and appearance of the suspected abnormality
Identify nearby nerves and blood vessels
Select an appropriate procedural approach
Monitor the needle or instrument as it advances
Observe tissue movement or fluid distribution
Reassess the region during follow-up
Ultrasound findings must still be interpreted in the context of the patient’s symptoms and examination. Structural abnormalities are common and are not always painful.
Evaluation and Patient Selection
The decision to perform a percutaneous procedure should follow a diagnosis-driven evaluation. This may include:
The location and pattern of symptoms
Activities that provoke or relieve pain
Functional limitations
Physical examination findings
Prior imaging and treatment
Tendon strength and integrity
The presence of partial or full-thickness tearing
Neurologic symptoms
Rehabilitation quality and duration
Occupational, athletic, and recovery goals
A procedure may be less appropriate when the primary problem is major tendon disruption, instability, infection, an unrecognized nerve disorder, or a condition requiring surgical repair.
The evaluation may also reveal that the tendon is not the primary pain source. In those cases, treatment may be redirected toward the joint, bursa, peripheral nerve, spine, or movement pattern rather than proceeding with tendon intervention.
How These Procedures Fit With Rehabilitation
Percutaneous treatment is usually one part of a broader recovery plan. The procedure addresses a defined tendon, fascial, or soft-tissue target, while rehabilitation helps restore strength, mobility, tissue tolerance, and confidence with activity.
Depending on the condition and procedure, the recovery plan may include:
Temporary activity modification
A staged tendon-loading program
Physical therapy focused on progressive strengthening, movement mechanics, and biomechanical factors
Bracing or footwear modification when appropriate
Gradual return to work, exercise, or sport
For active patients and athletes, Sports Medicine principles may also guide the return-to-activity plan based on the specific tendon involved, the demands of the activity, and the stage of recovery.
Percutaneous Procedures and Advanced Injection Options
Tendon fenestration or tenotomy may sometimes be performed alone. In other situations, a separate injection-based treatment may be discussed based on the diagnosis, tissue involved, prior treatment, and available evidence.
These options should not be automatically combined. Each component should have a specific clinical rationale.
Patients interested in platelet-rich plasma, bone marrow–derived procedures, or other biologic approaches can review Advanced Injection Options for a separate discussion of indications, limitations, and patient selection.
Recovery After a Tendon or Soft-Tissue Procedure
Recovery varies substantially by procedure and anatomical region. A small needle fenestration, ultrasonic tendon debridement, calcific deposit lavage, and peripheral nerve hydrodissection do not share the same recovery protocol.
Depending on the procedure, patients may require:
Brief protection of the treated area
Temporary lifting or activity restrictions
A brace, boot, or supportive device
Early range-of-motion exercises
Delayed or progressive tendon loading
Structured physical therapy
Gradual return to higher-impact activity
Post-procedure soreness does not necessarily indicate a complication, but increasing pain, substantial swelling, drainage, fever, progressive weakness, or new neurologic symptoms should be promptly evaluated.
When Surgery May Be the Better Discussion
Percutaneous treatment is not a substitute for surgery when a tendon requires repair, when structural failure is substantial, or when another surgically correctable problem is the primary cause of symptoms.
Surgical consultation may be appropriate when there is:
A full-thickness or high-grade tendon tear
Significant loss of strength or function
Tendon retraction
Major instability
Progressive neurologic deficit
Failure of appropriately selected nonoperative treatment
A structural condition unlikely to improve with a percutaneous procedure
Even when surgery is ultimately needed, preoperative treatment and rehabilitation may help improve mobility, strength, conditioning, and postoperative readiness when clinically appropriate.
A Diagnosis-Driven Approach
The value of an image-guided procedure depends on selecting the correct tissue, the correct treatment, and the correct stage of recovery.
At Network Spine, percutaneous tendon and soft-tissue procedures are considered within a broader osteopathic, musculoskeletal, and functional evaluation. The purpose is to determine not only what appears abnormal on imaging, but whether that finding explains the patient’s symptoms and whether treating it is likely to improve function.
Frequently Asked Questions
Is tendon fenestration the same as tenotomy?
The terms are sometimes used interchangeably. Tendon fenestration or percutaneous needle tenotomy generally describes repeatedly passing a needle through a targeted region of abnormal tendon. Other forms of percutaneous tenotomy may use a specialized ultrasonic instrument to remove selected tissue.
Is Tenex the same as percutaneous tenotomy?
Tenex® is a commonly recognized system used for percutaneous ultrasonic tenotomy and debridement. It is one method of performing a percutaneous tendon procedure, but it is not synonymous with every form of tendon fenestration or tenotomy.
Is hydrodissection a tendon procedure?
No. Hydrodissection is primarily used around a peripheral nerve. It may appear on the same page because nerve entrapment can coexist with or resemble tendon and soft-tissue pain.
Does an abnormal tendon ultrasound mean I need a procedure?
Not necessarily. Tendon abnormalities may be present without causing symptoms. Imaging findings should match the location of pain, examination findings, functional limitations, and clinical history before a procedure is considered.
Does tenotomy replace physical therapy?
No. A percutaneous procedure may address a selected tissue target, but rehabilitation remains important for restoring strength, tendon capacity, movement control, and tolerance for activity.
How long is recovery?
Recovery depends on the tissue treated, severity of the condition, procedure performed, and physical demands of the patient. A personalized rehabilitation and return-to-activity plan should be established before treatment.
