Muscle atrophy, also known as muscle wasting or muscle loss, is a common consequence of surgical procedures. It refers to the loss of muscle mass and strength, which can occur due to immobility and decreased physical activity during the recovery period. The impact of post-surgical muscle atrophy depends on its severity and duration, with longer periods of immobilization resulting in more significant muscle loss. To address muscle atrophy caused by surgical errors, patients often undergo physical therapy and exercise programs to speed up recovery. These exercises focus on strengthening and stretching the affected muscles, and may include resistance training, aerobic exercises, and balance training. In addition, targeted treatments such as ultrasound therapy and mitochondrial therapy can aid in stimulating muscle recovery. While muscle atrophy can be a challenging complication of surgery, proper rehabilitation and a comprehensive recovery plan can help minimize its effects and promote optimal healing.

Exercise and physical therapy
Muscle atrophy, or muscle wasting, is the loss or thinning of muscle mass. It can be caused by muscle disuse, neurogenic conditions, malnutrition, age, genetics, or certain medical conditions. Surgical procedures that require restricted movement during recovery can lead to muscle atrophy, particularly in muscles closest to the surgical site.
For muscle atrophy caused by surgical errors, the exercises prescribed will depend on the specific muscles affected and the individual's recovery stage. Generally, exercises that promote both muscle strengthening and stretching are beneficial. Examples include resistance training, aerobic exercises, balance training, and flexibility exercises to improve the range of motion. Functional exercises, such as squats, can help target and rebuild strength in areas commonly affected by muscle atrophy, such as the lower body. Leg raises are another effective exercise to strengthen the quadriceps and hip flexors, improving lower body strength and mobility. Push-ups are a great form of resistance exercise to improve upper body strength without the need for equipment.
In addition to these targeted exercises, maintaining an active lifestyle within one's limitations is essential for minimizing muscle atrophy. Ultrasound therapy is another physical therapy technique that utilizes sound waves to stimulate contractions in atrophied muscle tissue and promote healing. Electrical stimulation, a special type of physical therapy, can be used to treat neurogenic atrophy by sending electrical impulses to the nerves and muscles, causing them to contract and maintain muscle mass and strength.

Surgery-induced cortisol release
Surgery is a stressor that induces a systemic stress response, resulting in increased adrenal cortisol production. The cortisol response is influenced by the invasiveness of the surgical procedure, with more invasive surgeries causing a more pronounced cortisol surge. This surge is particularly evident in older patients, women, and those undergoing open surgery or general anaesthesia. The duration of the surgery and the type of anaesthesia used do not seem to impact the cortisol response.
The controlled trauma of surgery activates adaptive changes in the neuro-hormonal system and the inflammation response. Specifically, trauma and subsequent surgery trigger the release of corticotropin-releasing hormone (CRH) and arginine vasopressin (AVP) from the hypothalamus. This, in turn, stimulates the pituitary gland to release adrenocorticotropic hormone (ACTH), which ultimately leads to increased cortisol secretion by the adrenal cortex. Cortisol then acts in a negative feedback loop to decrease CRH and ACTH secretion.
The cortisol stress response after surgery has been shown to have substantial effects on various physiological processes. It can impact metabolism, water and electrolyte balance, and the cardiovascular, nervous, and immune systems. For instance, cortisol helps to alleviate inflammation by reducing the number of inflammatory cells and stabilising membranes. It also elevates blood glucose levels and increases blood pressure.
While surgery can induce a cortisol stress response, the precise impact of this response remains to be fully understood. There is a lack of standardised measurements and heterogeneous study designs, making it challenging to define the response reproducibly. Additionally, the expected cortisol levels during and after musculoskeletal surgery are not well-defined, and corresponding guidelines and treatment concepts are lacking. However, it is important to recognise that surgery-induced cortisol release is a dynamic process influenced by patient-specific factors, surgical techniques, and anaesthetic approaches.

Rehabilitation exercises
Muscle atrophy refers to the loss of muscle mass and strength. It can be caused by a lack of physical activity during the recovery period after surgery. The impact of post-surgery muscle atrophy depends on the severity and duration of muscle disuse. Generally, the longer the period of immobilization, the more significant the muscle loss.
Water-based exercises
Swimming and water exercises are often recommended for patients recovering from muscle atrophy. Water activities can dull muscle pain, quickly tone atrophied muscles, rebuild muscle memory, and relax sore muscles. Start with simple exercises, such as walking in waist-deep water for 10 minutes, and gradually increase the time and water depth as you progress.
Leg raises
Leg raises target the quadriceps and hip flexors, helping to maintain lower body strength and improve mobility. Lie on your back with one leg bent and the other straight. Slowly lift the straight leg to a 45-degree angle, and then lower it back down.
Squats
Squats are an excellent way to target the quadriceps, hamstrings, and glutes. Stand with your feet shoulder-width apart and lower your body by bending your knees and hips as if sitting back into a chair. Keep your chest up and knees aligned with your toes. Squats help rebuild strength and improve balance and stability.
Range of motion exercises
These exercises focus on improving the range of motion of the affected joints. For example, you can try sitting on a chair and sliding your hips off the seat while keeping your knees bent. Lower yourself slightly by bending your elbows and then push yourself back up to the starting position.
Resistance training
Resistance training helps to strengthen the muscles. This can include exercises such as push-ups or using light weights.
Aerobic exercises
Also known as cardiovascular activities, aerobic exercises help to improve your endurance and the health of your heart and lungs. This can include activities such as walking, jogging, swimming, or cycling.
Remember to always consult with your healthcare provider or physical therapist to determine the most appropriate rehabilitation exercises for your specific condition and recovery stage. They can guide you in tailoring an exercise routine that is safe and effective for your recovery journey.

Nutrition and diet
Muscle atrophy, or muscle wasting, refers to the loss of muscle mass and strength. It can be caused by a variety of factors, including immobility, decreased physical activity, malnutrition, age, genetics, and certain medical conditions. Post-surgery muscle atrophy is a common consequence of surgical procedures that require restricted movement or reduced physical activity during the recovery period.
Adequate Protein Intake
Consuming sufficient high-quality protein is essential for maintaining and building muscle mass. The recommended daily allowance (RDA) for protein is 0.8 grams per kilogram of body weight. However, some experts suggest that older individuals may require more protein, ranging from 1 to 1.2 grams per kilogram of body weight. Protein sources such as lean meats, fish, dairy, eggs, beans, and protein powders can help meet these requirements.
Vitamins and Antioxidants
Vitamins, particularly vitamin D, and antioxidants such as zinc, vitamin E, selenium, and Coenzyme Q10, play a vital role in muscle health and can help prevent and treat muscle atrophy. A balanced diet rich in fruits, vegetables, and healthy fats can provide these essential nutrients.
Nutritional Supplements
In some cases, nutritional supplements may be recommended to support muscle health and recovery. Amino acids, such as leucine and creatine, antioxidant supplements, minerals like magnesium, and vitamins can be beneficial. Probiotics and prebiotics may also be considered as part of a comprehensive nutritional strategy.
Healthy Diet Patterns
A typical Western diet, characterized by high consumption of processed foods, refined grains, red and processed meats, and sugary drinks, has been linked to increased muscle loss with age. Adopting a healthier dietary pattern, such as the Mediterranean diet, which emphasizes whole foods, lean proteins, healthy fats, fruits, and vegetables, can promote muscle health and reduce atrophy.
Individualized Nutrition Plans
It is important to recognize that nutritional needs vary among individuals. Working with a registered dietitian or nutritionist can help create a personalized nutrition plan that addresses specific needs and considerations related to muscle atrophy. They can provide guidance on appropriate macro and micronutrient distribution, supplement recommendations, and meal planning to support muscle recovery and overall health.

Hormone replacement
Muscle atrophy, or muscle wasting, refers to the loss of muscle mass and strength. It can be caused by muscle disuse, malnutrition, age, genetics, or certain medical conditions. Following surgery, muscle atrophy can occur due to restricted movement or decreased physical activity during the recovery period.
To address post-surgical muscle atrophy, physical therapy and exercise programs are often recommended. These may include range-of-motion exercises, strength training, and cardiovascular activities tailored to the individual's condition and recovery stage. In addition, proper nutrition is important to support muscle growth and recovery.
In terms of hormone replacement, there is growing evidence to suggest that estrogen and estrogen-based hormone therapy (HT) can play a beneficial role in the maintenance and enhancement of muscle mass, strength, and connective tissue. Estrogen exhibits anabolic properties in skeletal muscles, and HT has been found to enhance muscle recovery, particularly in aging females. This makes it especially relevant for postmenopausal women, who experience a natural decline in estrogen levels, resulting in a loss of skeletal muscle mass and strength.
In certain cases, human growth hormone (HGH) treatment may also be considered to prevent the loss of muscle strength following specific injuries or surgeries. For example, HGH treatment after ACL reconstructive surgery has been found to help athletes maintain muscle strength in the knee. However, it is important to note that HGH supplements are banned in collegiate and professional sports as they are considered performance-enhancing.
