The article will also delve into surgical interventions for severe cases, providing a well-rounded understanding of this challenging condition to help individuals manage and overcome medial epicondylitis effectively.
Pathophysiology of Golfer’s Elbow
Golfer’s elbow, medically known as medial epicondylitis, is a condition that arises from the overuse or repetitive stress of the flexor-pronator muscles attaching to the medial epicondyle of the humerus. The pathophysiology of this condition involves a complex interplay of tendon degeneration, inflammatory responses, and healing mechanisms.
Tendon Degeneration Process
The primary cause of golfer’s elbow is the repetitive microtrauma to the common flexor tendon, particularly the pronator teres and flexor carpi radialis tendons. Over time, this repetitive stress leads to microscopic tears within the tendon fibers, resulting in a degenerative process known as angiofibroblastic hyperplasia or tendinosis. As the tendon undergoes this degenerative process, there is a disorganization of collagen fibers, increased mucoid ground substance, and focal necrosis or calcification. The accumulation of these changes weakens the tendon structure, making it more susceptible to further injury and impairing its ability to heal effectively.

Inflammatory Response
Although the term “epicondylitis” suggests an inflammatory process, studies have shown that chronic cases of golfer’s elbow exhibit minimal evidence of inflammation. Instead, the condition is characterized by angiofibroblastic changes and the formation of immature fibroblasts and vascular structures. However, in the early stages of golfer’s elbow, an inflammatory response may be present. This acute inflammation is a natural reaction to the initial microtrauma and is mediated by various inflammatory cells and cytokines. The inflammatory phase is crucial for initiating the healing process, but if it persists, it can contribute to the development of chronic tendinosis.
Healing Mechanisms
The healing process of the damaged tendon in golfer’s elbow is often impaired due to the poor vascular supply and the continuous strain placed on the affected area. The body attempts to repair the microscopic tears by forming scar tissue, which is less elastic and more prone to further injury compared to healthy tendon tissue. Moreover, the healing process in golfer’s elbow can be disrupted by the presence of degenerative changes within the tendon. The accumulation of immature fibroblasts and disorganized collagen fibers hinders the formation of a strong, resilient tendon structure, leading to a chronic cycle of injury and inadequate healing. Understanding the complex pathophysiology of golfer’s elbow is essential for developing targeted treatment strategies that address the underlying tendon degeneration, manage inflammation, and promote effective healing. By addressing these key aspects, healthcare professionals can help patients with medial epicondylitis recover from this challenging condition and prevent future recurrences.
Clinical Evaluation
A thorough patient history and physical examination are essential for diagnosing golfer’s elbow (medial epicondylitis). Patients typically report an insidious onset of aching pain that radiates from the medial epicondyle down to the forearm and wrist. The pain is often exacerbated by activities involving wrist flexion, forearm pronation, or gripping. In some cases, patients may also experience elbow stiffness, weakness, numbness, or tingling, particularly in the ulnar nerve distribution.
Patient History
When taking a patient’s history, it is crucial to inquire about any repetitive elbow use, gripping, or valgus stress that may have contributed to the development of medial epicondylitis. This includes activities such as golf, tennis, swimming, pitching, and javelin throwing, as well as occupational tasks like lifting and passing heavy objects. The onset of symptoms, whether acute or insidious, should also be noted, along with any history of trauma or previous elbow injuries.

Physical Examination Techniques
During the physical examination, the clinician should inspect the medial aspect of the elbow for any swelling, erythema, or warmth. Palpation of the medial epicondyle, approximately five to ten millimeters distal and anterior, may reveal tenderness, especially near the conjoined tendon or muscles like the pronator teres and flexor carpi radialis. Range of motion is usually normal, but resisted pronation or flexion of the wrist can elicit pain in patients with golfer’s elbow.
Special Tests for Golfer’s Elbow
The golfer’s elbow test, also known as the medial epicondylitis test, is a specific maneuver used to diagnose this condition. The test has both an active and a passive component. In the active component, the patient resists wrist flexion with the arm in extension and supination. The passive component involves wrist extension with the elbow in extension. A positive test is indicated by the patient experiencing pain during these maneuvers. Additionally, Tinel’s test should be performed to evaluate for ulnar neuropathy, and the ulnar collateral ligament should be stressed, particularly in throwing athletes.
Advanced Treatment Modalities
Platelet-Rich Plasma (PRP) Therapy
PRP therapy has emerged as a promising treatment option for golfer’s elbow (medial epicondylitis). PRP is an autologous blood product containing a high concentration of platelets and growth factors that promote tissue healing and regeneration. In a study by Varshney et al., PRP injection demonstrated a 91% improvement in pain scores at 6 months compared to 42.2% with corticosteroid injection in patients with elbow epicondylitis. Although more research is needed, PRP therapy shows potential as an effective treatment for this condition.
Extracorporeal Shock Wave Therapy
Extracorporeal shock wave therapy (ESWT) has been investigated as a non-invasive treatment for medial epicondylitis. ESWT involves the application of high-energy acoustic waves to the affected area, which is thought to stimulate healing and reduce pain. A study by Suresh et al. found that ESWT combined with autologous blood injection led to significant improvements in pain and function scores at 10 months follow-up in patients with chronic medial epicondylitis. However, the optimal treatment protocol and long-term efficacy of ESWT for golfer’s elbow require further investigation.
Ultrasound-Guided Procedures
Ultrasound guidance has been increasingly used to enhance the accuracy and efficacy of interventional procedures for golfer’s elbow. Ultrasound allows real-time visualization of the affected tendons, enabling precise needle placement for injections or tenotomy. In a study by Suresh et al., ultrasound-guided autologous blood injection combined with needle fenestration resulted in significant improvements in pain and function scores at 10 months follow-up. The use of ultrasound guidance may optimize treatment outcomes and minimize complications associated with blind injections in the management of medial epicondylitis.
Surgical Interventions
Indications for Surgery
Surgery for golfer’s elbow (medial epicondylitis) is typically considered when conservative treatment options have failed to provide relief after 6-12 months. The goal of surgery is to remove the diseased tissue around the medial epicondyle, improve blood supply to the area to promote healing, and alleviate symptoms. Patients with severe functional impairment or those who have received multiple steroid injections may also be candidates for surgical intervention.

Surgical Techniques
The most common surgical technique for treating medial epicondylitis is an open procedure involving a small incision over the medial epicondyle. The diseased tendon, usually the flexor carpi radialis or pronator teres, is identified and removed. The bony attachment is then scraped to promote healing, and the healthy tendon is sutured back together. Other techniques, such as the mini-open muscle resection and fascial elevation and tendon origin resection (FETOR), have also been described in the literature.
Post-Operative Care and Rehabilitation
Following surgery, the elbow is immobilized in a splint or brace for approximately 6 weeks to allow the involved tendon to heal. During this time, patients can perform light activities. Physical therapy is initiated once the splint is removed, focusing on restoring range of motion and gradually increasing strength. Most patients can expect to resume normal activities within 12 weeks post-surgery, depending on their progress and the extent of their injury. Adherence to a comprehensive rehabilitation program is crucial for optimal recovery and prevention of recurrence.
