Tenolysis Surgery (Tendon Release): Procedure, Benefits, and Recovery

Tenolysis surgery is a professional tendon release procedure performed to eliminate the problem of tendon adhesion that develops after hand injuries or surgical repairs. This intervention, which requires plastic and aesthetic surgery expertise, ensures the meticulous cleaning of hardened scar tissues that restrict the natural gliding movement of the fingers. When these obstacles that disrupt the biomechanical function of the hand are surgically released, the patient’s muscle strength is transmitted to the bones again and restricted hand functions are anatomically restored. This procedure, which comes into play when physical therapy can no longer progress, is a technical touch that directly improves the hand’s gripping ability and mobility by resolving the mechanical blockage in finger movements.

What Is Tenolysis Surgery (Tendon Release)?

Our hands are one of the most flawless and complex mechanisms in the human body. The most important structures that allow this mechanism to work smoothly are tendons. You can think of tendons as extremely strong pulling ropes inside the hand that transmit the power produced by the muscles to the bones. These ropes must glide with millimetric precision through special sheaths and pulley systems within the narrow and complex anatomical structure of the hand. In a healthy hand, this gliding movement is smooth and occurs without catching anywhere. However, when tendons are injured, crushed, or ruptured by any cutting tool, a natural healing process begins. The body produces scar tissue, its own biological adhesive, to repair the damaged area.

This scar tissue, which is a natural part of the healing process, unfortunately does not always remain within its own boundaries. Sometimes the body reacts excessively and creates more scar tissue than necessary. This causes the tendon to adhere firmly to the tunnel it should glide through, the surrounding bones, and the skin. Imagine the brake cable of a bicycle rusting and sticking to the plastic sheath around it; no matter how much you squeeze the brake, the brake will not work because the cable cannot move. Tendon adhesion is also such a mechanical locking. Tenolysis surgery is a rescuing procedure that enables these biological adhesions to be cleaned at a microscopic level and restores the tendon’s free gliding distance within its anatomical sheath.

Why Does Tendon Adhesion Occur Before Tenolysis?

Tendon healing is a very fascinating but equally risky biological process. When a tendon is surgically sutured, healing basically progresses through two routes. First, the cells within the tendon’s own structure work to unite the ruptured ends. This is called intrinsic healing. Second, healing cells from the surrounding tissues, blood vessels, and sheaths outside the tendon almost flood into the damaged area. This extrinsic healing mechanism allows the ruptured tendon to fuse much faster and reduces the risk of rupture. This process, which is extremely beneficial at the beginning, can turn into the biggest obstacle over time.

When these reparative cells coming from the surroundings finish their work, instead of leaving the area, they may leave thick, hard, and very stubborn fibrotic bands between the tendon and the surrounding tissues. In anatomical regions such as the hand, where everything works within millimetric spaces, even a tiny adhesion on the surface of the tendon is enough to lock the movement of the entire finger. These adhesions do not occur because the surgeon performed the operation poorly; they occur due to many different reasons such as the patient’s genetic tendency for wound healing, the severity of the injury, the extent of tissue crushing, and insufficient movements performed in the early period.

What Are the Symptoms of Tendon Adhesion Indicating the Need for Tenolysis?

There is a very clear and surprising clinical indicator for understanding whether there is tendon adhesion in a finger. This indicator is the huge difference between active movement and passive range of motion. Passive movement is the bending of the finger with the help of an external force. For example, if you can close the finger by holding and bending your problematic finger with your other healthy hand, this proves that there is no arthritis or permanent stiffness in your joints. The joints are healthy, the doors are open, but the rope that will pull the door is not working.

Active movement, on the other hand, is trying to bend your finger only with your own muscle strength, by giving a command from your mind, without any external help. If that finger, which can be bent easily with external intervention, remains in place like a stone or moves very little when you try to close it yourself, this is the clearest proof that the tendon inside is firmly adhered to the surrounding tissues. Since the finger cannot bend, even the simplest actions in daily life, such as holding a glass, buttoning a shirt, or turning a door lock, become impossible.

The main symptoms indicating tendon adhesion are as follows:

  • Restricted active movement
  • Normal passive movement
  • Weak grip strength
  • Loss of fine motor skills
  • Feeling of tension in the hand

At What Stage Is the Decision for Tenolysis Surgery Made?

The decision for tenolysis surgery is never a hasty decision that can be made just a few weeks after the initial tendon repair surgery. According to medical principles, it is absolutely necessary to wait for a period of at least 3 to 6 months after the first surgery or injury. This long waiting period is not a randomly chosen period of time, but a necessity completely related to the natural rhythm of human biology and wound healing. Interventions performed in the early period cause the body to react even more severely and create adhesions worse than before.

During these months, the edema in the surgical area is expected to completely subside, the tissues to mature, and the hard scar tissue produced to stretch and soften. At the same time, during this period, the patient is required to continue a very intensive and disciplined physical therapy program. If no millimetric progress can be achieved anymore in the patient’s active range of motion despite months of difficult exercises, stretching movements, and massages accompanied by a physiotherapist, it means that the process has entered the plateau phase. At this point, when all non-surgical options have been exhausted and it is understood that the tissue can no longer open on its own, the decision for tenolysis surgery is made.

How Is Tenolysis Surgery Performed?

Tenolysis surgery is one of the most elegant, patience-requiring, and meticulous operations of hand surgery, almost like walking through a microscopic minefield. The main goal is to clean the cement-like hardened adherent tissues surrounding the delicate tendon, which has already been damaged once, ruptured, and sutured again, without causing even the slightest new damage to it. Therefore, the operation is performed not with standard glasses, but under special surgical magnifiers that enlarge the tissues many times, using very fine instruments.

The surgical procedure is usually started by following the old surgical scars on the patient’s hand. However, depending on the size of the adhesions, the surgeon may need to make new zigzag-shaped incisions or incisions progressing from the sides of the finger in order to widen the field of view. After the skin is passed, the tendon sheath is opened very carefully. Each point where the tendon is adhered is identified millimeter by millimeter and separated from the surrounding bands with the help of special micro scissors. During this procedure, it is vital to preserve the capillary networks that attach the tendon to the bone and provide its blood supply. In addition, the pulley systems that prevent the tendon from moving away from the bone should not be damaged by this cleaning, and if they are damaged, they must be reconstructed.

What Is the WALANT Technique Used During Tenolysis?

The greatest revolution achieved in tenolysis surgeries in modern hand surgery is the WALANT technique. This abbreviation, formed from the initials of English words, refers to a special local anesthesia method in which the patient is fully awake and the tourniquet device that squeezes like a blood pressure cuff to stop blood flow in the arm is not used. This technique both increases patient comfort and dramatically raises the success rate of the surgery.

About half an hour before the surgery, a special solution is injected only into the area to be treated. This mixture contains a local anesthetic substance that completely eliminates pain, epinephrine that stops bleeding and allows the surgeon to clearly see the surgical field, and sodium bicarbonate that eliminates the burning sensation during the injection. The most critical point occurs right in the middle of the surgery. When the surgeon thinks that the adhesions have been cleaned, he asks the fully awake patient to bend the finger on the table. When the patient bends the finger with their own muscle strength, the surgeon watches the tendon’s glide inside like a live video. If even a small catching point remains, he sees it instantly and releases it. Thus, the patient’s leaving the operating room with definite success is guaranteed while still on the table.

Recovery Process After Tenolysis Surgery

After tenolysis surgery, the recovery process begins the moment the patient first moves the finger on the operating table. Unlike many surgeries, after tenolysis, placing the operated area in a cast and resting it is the biggest and most destructive mistake that can be made. Resting means giving the body the opportunity for the cleaned tissues to adhere to each other again in a much harder way. The recovery process is a very active, effort-requiring, and long marathon divided into weeks according to the stages of tissue healing.

The first weeks are entirely based on edema control and early movement. To prevent swelling in the fingers, the hand should be kept continuously above heart level. In the following weeks, as the resistance of the tissues increases, the intensity and frequency of the movements are also increased. From the second month onward, a new and smooth gliding tunnel begins to form around the tendon. During this period, pain decreases and finger functions return. By the third month, the patient reaches a level at which they can do almost all of their daily tasks without difficulty. However, preserving and making this gained range of motion permanent depends entirely on the patient’s unwavering will during this process.

Which Exercises Are Performed During the Physical Therapy Stage After Tenolysis?

The physical therapy stage is undoubtedly the most important complement of tenolysis surgery. There are special “tendon gliding exercises” taught to the patient by physiotherapists and required to be repeated perhaps hundreds of times a day. The purpose of these exercises is to train the different tendon groups inside the hand to move along independent paths without rubbing against each other. The exercises may be quite painful and challenging at first, but this pain is part of healing.

In the movement called hook fist, only the tip and middle joints of the fingers are bent to form a hook shape. This works the deep tendons over the maximum distance. In the straight fist movement, the base parts of the fingers are kept straight and bending is provided only from the middle joints. In the full fist movement, the hand is completely clenched normally and the entire tendon system is aimed to work together. Performing these movements in a disciplined way throughout the day prevents the clean tunnel opened by the surgeon during the operation from closing again by creating a physical barrier.

The main exercise and movement types applied are as follows:

  • Hook fist
  • Straight fist
  • Full fist
  • Passive stretching
  • Resisted gripping
  • Isolated joint bending

Things Those Who Have Had Tenolysis Surgery Should Pay Attention To

The permanent success of a tenolysis operation depends as much on the surgeon’s skillful touches on the table as on the self-care discipline the patient will show in daily life after the surgery. How the patient treats their own body and the surgical area is the main factor that determines whether the result will be excellent or return to its former state. Therefore, there is a series of very strict but logical rules that patients must follow.

In the first stage, wound care and hygiene must be flawless. In order to prevent the surgical incisions from becoming infected, it is essential that the operated area does not come into contact with water at all and is kept clean and dry during the approximately two-week period until the stitches are removed. Dressings should be renewed as often as the doctor recommends and should be changed without delay when they become dirty. In addition, although exercising is mandatory, movements that will suddenly place excessive load on the tendon should be avoided. Carrying grocery bags in the operated hand, trying to force open a stuck jar lid, or squeezing a wet cloth with all one’s strength may cause damage to the not-yet-fully-healed and sensitized tendon. The balance between exercise and daily life activities must be established very well.

Which Foods Accelerate Recovery After Tenolysis?

Tendon healing is a process that requires high energy and correct building blocks at the cellular level. Nutritional support taken from outside is of great importance for the body to perform healthy repair in the surgical area and to produce flexible and durable connective tissues. In a body that is poorly and insufficiently nourished, the repair rate of cells slows down, the immune system weakens, and the recovery of the surgical area may be delayed for weeks.

In particular, consuming protein-rich foods is essential to support collagen production, which is the main building block of tissues. Vitamin C, which accelerates cell renewal, zinc, which supports wound closure, and Omega-3 fatty acids, which reduce inflammation, that is, tissue inflammation, are the patient’s greatest helpers during this period. A balanced and rich table is a healer as effective as medicines.

The main foods that support the recovery process are as follows:

  • Bone broth
  • Egg
  • Salmon
  • Orange
  • Kiwi
  • Spinach
  • Almond
  • Walnut
  • Kefir

Which Habits Should Be Avoided During the Tenolysis Recovery Process?

Just as there are factors that support the recovery process, there are also very dangerous habits that completely sabotage this process and carry the risk of wasting all the gains of the surgery. For tissue repair to progress healthily, cells need a constant and abundant amount of oxygen. Any factor that prevents oxygen from reaching the tissues is the number one enemy of wound healing.

At this point, smoking is indisputably the greatest danger. Nicotine in cigarettes severely narrows all capillaries in the body and reduces blood flow to the surgical area almost like turning down a tap. Since tendons naturally have very poor blood supply, when the constricting effect of smoking is added on top of this, it becomes impossible for the tendon to heal and produce lubricating fluids. In patients who smoke, the likelihood of tendon rupture and the formation of new adhesions is much higher.

Things that must absolutely be avoided during this sensitive period are as follows:

  • Smoking
  • Electronic cigarette
  • Alcohol
  • Excessively sugary foods
  • Processed packaged products
  • Heavy lifting
  • Sudden hand movements

What Situations Require Emergency Intervention After Tenolysis?

As with every surgical intervention, some warning signals that the body may give after tenolysis should be monitored closely. The recovery period generally progresses in a predictable order, but sometimes situations may occur inside that are not going well. Although pain and swelling are natural results of the surgery, symptoms that change character and gradually become more severe should never be ignored.

Especially if a finger that could be bent very comfortably the day before cannot be moved in any way the next day, this may be the greatest indicator that the tendon has ruptured because it could not withstand the strain. In addition, whitening, bruising, or persistent numbness at the fingertips despite keeping the hand constantly elevated indicates impaired blood circulation in the area. Severe redness, increased warmth, and throbbing pain beginning at the wound site signal that infection is approaching.

The main warning signs requiring emergency medical evaluation are as follows:

  • Severe bleeding
  • Foul-smelling discharge
  • Sudden loss of movement
  • Persistent high fever
  • Bruising at the tips
  • Unexpected numbness
  • Throbbing pain

How Should Long-Term Expectations Be After Tenolysis Operations?

After tenolysis surgery, the biggest question in patients’ minds is whether their hands will become completely flawless as before. In scenarios where it is performed at the right time, the surgical technique works perfectly, and the patient fully complies with physical therapy, the vast majority of patients return to their daily lives without feeling any restriction. Range of motion increases enormously and the hand largely regains its functionality.

However, as with every procedure in medicine, tenolysis also has realistic limits. If the initial damage in the patient’s hand was not a simple knife cut but, for example, a very severe crush injury caused by being caught under a press machine, expectations must be managed correctly. In very complicated cases where nerves are severed, vessels are torn apart, and joint cartilage is damaged, expecting a one hundred percent perfect hand after tenolysis as if no accident had ever happened is contrary to biology. In such severe cases, the main goal of surgery is not the aesthetic perfection of the hand, but reaching a functional level at which the patient can tie their shoelaces, hold their glass themselves, and perform personal care without being dependent on anyone.

What Factors Affect the Success of Tenolysis Surgery?

As a result, tenolysis surgery is the success not of a single person but of a team working in harmony. This team includes the surgeon who plans the operation, the physiotherapist who selects the correct exercises, and most importantly, the patient themselves, who endures all difficulties. When one link of the chain breaks, the efforts of the others will also be wasted. The patient’s motivation, the sweat shed after surgery, and the patience shown are a treatment tool as sharp and effective as the scalpel on the table.

The main building blocks that create this picture of success are as follows:

  • Correct surgical technique
  • High patient motivation
  • Early and safe movement
  • Regular physical therapy
  • Healthy wound care
  • Avoiding bad habits
