No Difference Between Surgery and Placebo Surgery For Tennis Elbow
elbow-pain-tennis-elbow-treatment

Tennis elbow or lateral epicondylalgia is a painful condition affecting the wrist and finger extensor tendons as they attach into the arm.  Breakdown of the tendon at its' insertion and weakness in the forearm muscles lead to pain and reduced tolerance for gripping and hand movements.  Physical Therapy treatments including manual therapy to the spine and extremity joints has been shown to accelerate recovery and lead to reduced healthcare utilization over the long term.  Importantly, manual therapy improves a patient's tolerance for strength training exercises which allow for long term relief.  Patient's who do not improve with conservative treatments may opt for surgical debridement of the injured tendon and muscle.  

A recent double blinded, randomized controlled trial compared the effectiveness of surgery to a sham or placebo surgery in patients with chronic tennis elbow pain (Krosiak et al. Am J Sports Med. 2018).  Patients were randomized to either a sham/placebo group (skin excision and exposure of the tendon) or a surgical debridement and excision of the affected tissue.  Interestingly, both groups improved pain and function at 6 month follow up but there were no significant differences between groups.  Authors stopped the study early due to the lack of differences between the surgical and placebo groups.  The authors reported no additional benefit of surgery over placebo for patients with chronic elbow pain.

Lateral Elbow Pain and Physical Therapy Solutions

Elbow pain on the outside of the elbow is most common in individuals’ aged 30-50 y.o. and effects 1-3% of the general population (Shiri et al. 2006).  Risk factors for this condition include blue collar workers utilizing repetitive gripping and manipulation in the work place, smokers, and tennis athletes.  This condition has previously been described as tennis elbow or tendonitis.  The first term is a non specific umbrella term and the second has been proven to be incorrect based on our current understanding of the pathophysiology behind this condition.  Tissue sampling of the wrist and finger tendons running along the outside of the tendon has failed to show any inflammatory cells making the term lateral epicondylosis, epicondylalgia, or lateral elbow tendinopathy more appropriate. 

These terms suggest a more degenerative condition consistent with increased cellular and collagen formation (Cook et al. 2009).  Our previous blog post detailed the ineffectiveness of anti-inflammatory treatments, including NSAIDs and corticosteroid injections, for the long term management of lateral elbow pain.  In fact, corticosteroid and platelet rich plasma (PRP) injections have been shown to have poor long-term outcomes and the highest rates of recurrence among conservative treatments (Coombes et al. 2013).  Recent evidence advocates for early diagnosis and management based on an individual’s unique presentation (Coombes et al. 2015).  Differences in the clinical presentation of this condition are normal and our examination and treatment must be based on the patient’s presentation.

Clinical examination involving pain at a patient’s lateral elbow, and pain with gripping or finger and wrist extension is consistent with lateral elbow pain.  Caution is advised to rule out competing diagnoses including referral from the neck, nerve entrapment, ligament tears, and elbow instability.  Clinicians should examine surrounding areas of the body to determine their impact on pain processing and/or   

Patients with higher levels of baseline pain and disability require early interventions due to the poor long-term prognosis associated with this presentation (Smidt et al. 2006).   This patient population may also present with greater symptoms at rest including night pain interfering with sleep patterns.  Another factor often associated in patients with lateral elbow pain includes concomitant musculoskeletal complaints in the neck and shoulder.   A treatment plan aimed at treating impairments in the upper quarter, in addition to the elbow, may accelerate recovery and reduce future recurrence (Cleland et al. 2005).

Conservative treatment remains a hallmark of lateral elbow tendinopathy.  The vast majorities of patients treated conservatively with either a wait and see approach or with Physical Therapy demonstrate improvements in pain and function at one year (Bisset et al. 2006).  The difference among treatment groups is secondary to the speed of recovery and economic impact seen in groups assigned to Physical Therapy.  Physical Therapy groups undergo a rapid improvement in the short term while the wait and see group takes up to 26 weeks to reach the same level of improvement.  This rapid improvement in symptoms leads to decreased costs due to decreased utilization of health care resources in the coming year.   The key question in the literature is what treatment should patients be provided with once they enter Physical Therapy. 

Manual therapy including spinal and extremity joint mobilization and manipulation has been shown to reduce pain processing and improve pain and function.  Pain free grip strength has immediately increased in response to these elbow interventions.  These techniques are designed to reduce pain and allow a faster transition to an exercise program. 

Exercise is one of the most important components of a treatment programs.  Upper quarter exercises have been shown to reduce time off work and future medical costs, as well as, improve work and ADL tolerance (Pienimaki et al. 1998).  Programs should gradually load the wrist extensors to restore coordination and strength to the tendon.  A more irritable patient will benefit from isometric exercise whereas a more chronic, less irritable condition will benefit from eccentric exercises.  Progression of the exercises should involve multi joint and functional movements to restore function in the upper quarter.

A recent review article suggests sub grouping patients based on their presenting signs and symptoms to best determine how to allocate these PT interventions (Coombes et al. 2015).  These authors suggest advice, NSAIDs, and a wait and see approach for patients without risk factors for long term disabiilty, low pain severity and disability.   Conversely, moderate and high risk patients with risk factors for long term disability, high pain and disability scores are most appropriate for pain medication and physical therapy interventions.

In conclusion, lateral elbow pain is not a homogenous condition and should be examined and treated based on an individual’s presentation for optimal outcomes.

Lateral Elbow Pain and Lateral Epicondylalgia

Lateral epicondylalgia, also known as tennis elbow, is an overuse injury involving the common origin tendon of the wrist and finger extensors. Patients with this condition often report pain in the lateral elbow exacerbated by gripping, lifting, or manipu- lating objects with their hands.

Previously thought to be a condition of inflammation (lateral epicondylitis), new research shows a lack of inflammatory cells in this condition. Instead, lateral epicondylalgia is considered a degenerative condition and one of dysfunctional, immature healing of the tendon(5,6). Tendons have been shown to remodel and heal along the lines of stress from exercise and appropriate loading(7).

4-7 cases per 1000 patients experience the condition and lateral epicondylalgia has a 1-3% incidence within the general population(1,2).

The condition primarily effects the dominant arm of individuals between 35-54 years old1. Amateur tennis players, patients with poor posture, frequent computer use, and manual tasks involv- ing force and repetition are at greater risk for the condition(2).

The majority of patients reports resolution of their symptoms by 1 year but may range up to 24 months(1).

Physical Therapy interventions have been shown to accelerate this recovery process and have been shown to be more cost effective than a wait and see approach or a corticosteroid injection(9). 

Elbow Pain and Physical Therapy Treatments

Review articles do not support the use of Physical Therapy modalities including ultrasound and iontophoresis in the treatment of lateral epicondylalgia(4).

Corticosteroid injections have been advocated for short term relief by many studies. While experiencing early relief, patients undergoing corticosteroid injections have a higher recurrence rate (72%) compared to a wait and see (10%) or Physical Therapy treatments (4%). (3)

Recent systematic report strong evidence against the utilization of platelet rich plasma (PRP) injections in patients with lateral elbow tendinopathy(12).

Evidence reviews on the topic of lateral elbow pain advocate for a multimodal Physical Therapy treatment model including spinal and extremity joint manipulation/ mobilization, soft tissue treatments, and strengthening exercises(4,13).

Physical Therapy Evidence

A manual physical therapy approach combined with exercise has been shown to accelerate a patient’s recovery by reducing pain and disability in the short term. Medical evidence has also shown patients receiving this treatment approach have the lowest recur- rence rate of pain and medication use(10,11).

Conversely, poorer long term outcomes and higher recurrence rates have been documented in patients receiving corticosteroid injections(10).

Bisset et al. reported the utilization of manual therapy and exercise is superior to wait and see and corticosteroid injection at short-term follow up11. It appears PT helps accelerate recovery and is superior to a wait and see approach.

Evidence suggests treatment of the upper quarter including the cervical, thoracic, elbow, and wrist regions may provide positive effects on patient’s pain and function(14).

When to Seek Physical Therapy Care

Patient’s with lateral elbow pain exacerbated by gripping or manipulation of the hand and wrist should be treated with a multimodal Physical Therapy treatment plan to reduce pain and disability.
