Tendinopathy

Not true inflammation — histology studies show degenerative angiofibroblastic changes in most chronic cases, not acute inflammation. “Tendinopathy” is the clinically accurate term.

ECRB

Key tendon in padel — the extensor carpi radialis brevis originates at the lateral epicondyle and is the most stressed attachment during backhand vibration loading on a padel racket.

Both types

Lateral and medial occur in padel — lateral epicondylitis from backhand and volley vibration; medial epicondylitis from forehand and smash pronation loads.

In short: epicondylitis means pain and degeneration at the bony elbow attachment of forearm muscles. Lateral (outer elbow, “tennis elbow”) is most common in padel from backhand vibration; medial (inner elbow, “golfer’s elbow”) comes from forehand pronation. Padel’s compact swings create repetitive vibration stress rather than single-swing overload — making it a different injury pattern from classic tennis elbow.

The Anatomy: What Are the Epicondyles?

The word epicondylitis breaks down as: epi (upon) + condyle (rounded bony prominence) + itis (inflammation). In practice, the epicondyles are two bony protrusions on the bottom of the humerus — the upper arm bone — at the elbow joint.
The lateral epicondyle sits on the outer (thumb) side of the elbow. This is where the wrist extensor muscles originate — particularly the extensor carpi radialis brevis (ECRB), which is the main culprit in lateral epicondylitis. When this tendon attachment degenerates under repetitive load, you feel pain on the outside of the elbow.
The medial epicondyle sits on the inner (little finger) side. Here the wrist flexor and forearm pronator muscles originate — the flexor carpi radialis and pronator teres being the key structures. Overload here produces medial epicondylitis.
Why “Tendinopathy” is More Accurate

Despite the “-itis” suffix implying inflammation, biopsy studies consistently show degenerative tissue changes (angiofibroblastic degeneration) rather than classic inflammatory cells at the epicondyle attachment. This matters for treatment: anti-inflammatory strategies alone are insufficient for chronic cases. Tendon loading — not just rest — is required to drive healing.

The tendons at these attachment sites are susceptible to repetitive loading stress that exceeds their recovery capacity. Once the collagen matrix begins to degrade, the tissue loses its normal architecture, becomes hypervascular, and develops the pain-producing changes we label epicondylitis.

Key Anatomical Facts to Know

Lateral epicondyle: outer elbow, extensor muscles, ECRB is the primary structure involved
Medial epicondyle: inner elbow, flexor and pronator muscles
Both attachments are at the distal humerus, not inside the elbow joint itself
Tendons here have relatively poor blood supply, which slows healing
Chronic epicondylitis involves tendinopathy (degeneration), not just inflammation

Lateral Epicondylitis in Padel

“Tennis elbow” — but the padel mechanism is different

Lateral epicondylitis — commonly called tennis elbow — is the most frequent elbow overuse injury in padel. The name is misleading in context: the loading pattern on a padel court is fundamentally different from that of a tennis baseline.
In padel, the compact backhand volley and groundstroke are the primary culprits. Because the padel glass walls shorten rallies and create a faster repetition rate, players execute far more backhand strokes per session than in tennis. Each stroke transmits vibration from the racket frame through the grip into the ECRB tendon at the lateral epicondyle.
Symptoms: Point tenderness directly over the lateral epicondyle (the bony bump on the outer elbow), pain on resisted wrist extension (pressing the back of your hand against resistance), pain when gripping — particularly on the backhand side — and morning stiffness that eases with light movement.
Grip and Racket as Risk Factors

A racket that is too stiff transmits more vibration to the ECRB. An overgrip that is too thin reduces cushioning. A grip size that is too small forces the forearm muscles to work harder to maintain control. All three are modifiable risk factors that are worth addressing before focusing exclusively on rehab exercises.

Medial Epicondylitis in Padel

“Golfer’s elbow” — less common, often underdiagnosed

Medial epicondylitis — golfer’s elbow — affects the inner elbow. In padel, it arises from three primary movement patterns: forehand topspin attempts that require forceful wrist flexion, smash follow-through where the forearm pronates aggressively through contact, and forehand volleys that combine wrist flexion and grip force under time pressure.
Symptoms: Tenderness on the medial epicondyle (inner elbow bump), pain on resisted wrist flexion (curling the palm towards the forearm against resistance), pain on resisted forearm pronation (turning the palm downward against resistance), and occasionally a radiating ache into the forearm during play.
Medial epicondylitis is less common than lateral in padel, but it is frequently underdiagnosed because players — and some clinicians — assume elbow pain is always on the outer side. If your pain is on the inner elbow, particularly worsened by forehand shots and smashes, medial epicondylitis is the more likely diagnosis.
Differentiating the Two Types Quickly

Press on the bony bump on the outer elbow (lateral) and the bony bump on the inner elbow (medial). Whichever is tender identifies the type. If both are tender, you may have a combined overuse pattern — less common but seen in high-volume players. Always confirm with a clinical assessment before starting a loading programme.

Medial Epicondylitis: Key Signs

Pain and tenderness on the inner elbow (medial epicondyle)
Worse with forehand shots, smashes, and grip under load
Pain on resisted wrist flexion and forearm pronation
Sometimes associated with ulnar nerve irritation (tingling in ring and little finger)
Less common than lateral but more often missed
You know the feeling — a nagging ache builds over weeks until one session you can barely grip the racket. Most players don’t realise that epicondylitis in padel follows a different timeline than tennis elbow: the compact repetition adds up quietly. What actually works is catching the load pattern early and adjusting before the tendon degenerates past the point of quick recovery.

Padel vs Tennis: A Different Injury Mechanism

Understanding why padel epicondylitis develops differently from the classic tennis version helps explain both the onset pattern and the best treatment approach.

Tennis Mechanism

High-force single events: the full-swing backhand and powerful serve create large peak loads at the ECRB attachment with each stroke. Fewer strokes per hour, higher force per stroke.

Padel Mechanism

Repetitive low-force vibration: compact swings with more shots per hour at lower peak force. Vibration from the glass-wall rebound and compact stroke pattern creates cumulative microtrauma over many repetitions.

Onset Pattern

Padel epicondylitis typically develops gradually over weeks of increased play volume, without a single “this is when it started” moment. This makes it easy to ignore until the tendon is significantly compromised.

This distinction matters clinically. Because the injury develops through volume overload rather than acute force overload, the most common trigger is a sudden increase in play frequency — returning after a break, starting a club season, or playing tournaments on consecutive days. The tendon does not have enough time between sessions to remodel and recover.
The implication for treatment is that load management is the first intervention — not complete rest, but a reduction in the aggravating repetition rate while maintaining some tendon stimulus to drive healing. This is why modern tendinopathy protocols start with isometric loading rather than weeks of inactivity.
Do Not Play Through Escalating Pain

A mild 2–3/10 ache that resolves within 24 hours of play can be managed with modified training. Pain that exceeds 5/10 during play, or that does not resolve overnight, is a signal the tendon is being overloaded beyond its current capacity. Continuing to play at that level accelerates tissue degeneration and extends recovery timelines significantly.

Treatment Overview

Phased loading — not rest — is the evidence-based approach

Modern epicondylitis management is built around progressive tendon loading, not prolonged rest. The four-phase framework below applies to both lateral and medial types, with exercise selection varying by which attachment is involved.
Four-Phase Rehabilitation Framework
01

Phase 1: Load Reduction (not rest)

Identify and reduce the specific aggravating movements — typically backhand volleys for lateral, smash follow-through for medial. Maintain other aspects of play where possible. Apply ice post-session for comfort (10–15 min). Avoid cortisone at this stage — evidence shows it provides short-term relief but worsens long-term tendon integrity.

02

Phase 2: Isometric Loading

Wrist extension isometrics (for lateral) or wrist flexion isometrics (for medial) at 70% of maximum voluntary contraction, held 30–45 seconds, 5 sets, daily. Isometrics produce immediate analgesic effects and maintain tendon stiffness without provoking the degeneration cycle. This phase typically lasts 2–4 weeks.

03

Phase 3: Eccentric and Slow Isotonic Loading

Transition to Tyler Twist (theraband flexbar exercise) for lateral epicondylitis, or wrist curl eccentric lowering for medial. 3 sets of 15 repetitions, slow tempo (3 seconds down), daily or every other day. This is the phase with the strongest evidence base for tendon remodelling and long-term recovery.

04

Phase 4: Sport-Specific Loading

Graded return to full training volume. Begin with baseline sessions (50% normal volume), monitor soreness rating over 24 hours, and increase by 10–15% per week if the tendon tolerates it. Full return to competition is the endpoint, not just pain resolution — the tendon must handle competitive load demands reliably.

A Note on Cortisone Injections

Cortisone injections provide short-term pain relief (weeks to 2–3 months) but multiple randomised controlled trials show significantly worse outcomes at 6 and 12 months compared with structured rehabilitation alone. If used, a single injection may be justified to enable initial loading — but it should not replace the loading programme.

For the complete rehabilitation protocol with exercise progressions, grip modifications, racket selection guidance, and return-to-play criteria, see the full Padel Elbow Pain treatment guide. If your symptoms involve the inner elbow, also see Padel Golfer’s Elbow for the medial-specific protocol.

Frequently Asked Questions

What is epicondylitis?

Epicondylitis is degeneration and pain at the bony attachment points of forearm muscles to the humerus (upper arm bone) at the elbow. Lateral epicondylitis (tennis elbow) affects the outer elbow where wrist extensor muscles attach; medial epicondylitis (golfer’s elbow) affects the inner elbow where wrist flexor and forearm pronator muscles attach. Despite the “-itis” suffix suggesting inflammation, most chronic cases involve tendon degeneration (tendinopathy) rather than true acute inflammation.

Is padel bad for tennis elbow?

Padel can aggravate existing lateral epicondylitis, particularly through repetitive backhand strokes and volleys that load the ECRB tendon attachment. However, padel does not have to mean stopping play altogether. With modified technique, appropriate racket and grip selection, and a structured loading programme, most players can continue playing at reduced volume while the tendon recovers. Total rest is not recommended in modern tendinopathy management — some tendon load is needed to drive healing.

What is the difference between lateral and medial epicondylitis?

Lateral epicondylitis (tennis elbow) affects the outer elbow and is caused by wrist extensor overload — typically from backhand strokes in padel. Medial epicondylitis (golfer’s elbow) affects the inner elbow and is caused by wrist flexor and pronator overload — from forehand strokes and smash follow-through. You can identify which type you have by pressing on the bony bump on the outer versus inner elbow: the tender side indicates the affected structure.

How long does epicondylitis take to heal in padel?

With a structured rehabilitation programme (isometric loading progressing to eccentric loading), most players see significant symptom improvement within 6–12 weeks. Full tendon remodelling and return to unrestricted play can take 3–6 months for established cases. Cases that are caught early and managed promptly recover faster. Ignoring symptoms and continuing to load the tendon without modification extends recovery timelines considerably.

Can I play padel with epicondylitis?

In most cases, yes — with modifications. The key is monitoring your pain level. A 2–3 out of 10 ache that resolves within 24 hours of play is generally acceptable during the rehabilitation phase. Pain above 5/10 during play, or symptoms that do not settle by the next morning, indicate that you are overloading the tendon and need to reduce volume or intensity. A counterforce elbow brace can help reduce peak tendon load during play. See the full padel elbow guide for a graded return-to-play protocol.

Why do padel players get epicondylitis differently from tennis players?

Tennis epicondylitis is typically caused by high-force, lower-repetition events — the full backhand swing and powerful serve produce large peak loads at the elbow attachment. Padel creates a different pattern: compact swings with higher repetition per hour at lower peak force, plus vibration transmitted through the racket from glass-wall rebounds. This means padel epicondylitis develops through cumulative microtrauma over many sessions rather than acute overload in one session — making it easier to overlook until the tendon is significantly compromised.
