Common Tennis Injuries: Beyond Tennis Elbow

When most people hear the phrase "tennis injury," their minds immediately go to tennis elbow. While lateral epicondylitis is certainly one of the most well-known conditions associated with the sport, it represents just one piece of a much larger injury landscape. Tennis is a demanding full-body sport that involves explosive sprinting, rapid directional changes, overhead serving, and repetitive ground strokes, all of which place significant stress on multiple joints and muscle groups. Here in Malaysia, where tennis continues to grow in popularity across the Klang Valley and beyond, understanding the full spectrum of tennis-related injuries is essential for players who want to stay on the court long-term.

At Kinesio Rehab in Putra Heights, Subang Jaya, we regularly treat recreational and competitive tennis players who present with injuries that extend far beyond the elbow. In this guide, we will explore the most common tennis injuries that players often overlook, discuss how court surfaces influence injury risk, and provide evidence-based prevention and recovery strategies.

Shoulder Impingement and Rotator Cuff Injuries

The shoulder is arguably the most vulnerable joint in tennis. The serve alone generates forces equivalent to throwing a baseball, and competitive players may serve hundreds of times during a single match or training session. Over time, the repetitive overhead motion compresses the rotator cuff tendons against the acromion, a bony projection at the top of the shoulder blade. This compression, known as subacromial impingement, is the most common shoulder complaint among tennis players.

The four muscles of the rotator cuff, specifically the supraspinatus, infraspinatus, teres minor, and subscapularis, work together to stabilise the humeral head within its shallow socket during the extreme ranges of motion demanded by serving and overhead smashes. When these muscles become fatigued or weak relative to the larger deltoid and pectoral muscles, the humeral head migrates upward, narrowing the subacromial space and irritating the tendons and bursa.

Early symptoms include a dull ache in the front or side of the shoulder during or after play, pain when reaching overhead, and difficulty sleeping on the affected side. If left untreated, impingement can progress to partial or full-thickness rotator cuff tears, which may require surgical intervention.

• Scapular stabilisation exercises: Strengthening the serratus anterior and lower trapezius helps maintain proper shoulder blade positioning during strokes, reducing impingement risk.
• External rotation strengthening: Using resistance bands to strengthen the infraspinatus and teres minor creates a muscular balance that protects the rotator cuff during high-velocity movements.
• Thoracic spine mobility: A stiff upper back forces the shoulder to compensate with excessive movement. Regular thoracic extension and rotation exercises help distribute the workload more evenly.

Wrist Sprains and TFCC Injuries

The wrist absorbs tremendous force with every forehand, backhand, and serve. Wrist sprains occur when the ligaments supporting the joint are stretched beyond their capacity, typically during off-centre ball contact or an awkward racquet grip at the moment of impact. The triangular fibrocartilage complex (TFCC), a cartilage structure on the pinky side of the wrist, is particularly vulnerable in tennis players who use heavy topspin on their forehands or who frequently hit one-handed backhands.

TFCC injuries present as pain on the outer edge of the wrist, especially during gripping, twisting motions, or pushing off the ground after a fall. Many players in the Subang Jaya and Petaling Jaya tennis clubs we work with initially dismiss wrist pain as minor, continuing to play through symptoms until the injury becomes chronic. Early assessment and a structured rehabilitation programme that includes progressive grip strengthening, proprioceptive training, and technique modification can prevent a minor sprain from becoming a long-term problem.

Knee Meniscus and Ligament Issues

Tennis requires constant starting, stopping, lunging, and pivoting, movements that place enormous shear and rotational forces on the knee joint. The menisci, two C-shaped pieces of cartilage that cushion and stabilise the knee, are particularly susceptible to injury during sudden changes of direction. A player who plants their foot and twists to reach a wide ball can tear the meniscus, experiencing sharp pain, swelling, and sometimes a catching or locking sensation in the joint.

The anterior cruciate ligament (ACL) and medial collateral ligament (MCL) are also at risk, especially during deceleration and lateral movements. While complete ACL tears are less common in tennis than in sports like football or futsal, partial tears and sprains do occur and can significantly impact a player's ability to move confidently on the court.

Knee injuries in tennis are closely linked to lower limb biomechanics. Weakness in the hip abductors and external rotators can cause the knee to collapse inward during lunging movements, increasing stress on the ligaments and menisci. A physiotherapy programme that addresses hip strength, quadriceps and hamstring balance, and movement patterns can substantially reduce injury risk.

Lower Back Pain in Tennis Players

The lumbar spine undergoes significant loading during tennis, particularly during the serve. The combination of hyperextension, lateral flexion, and rotation that occurs during the trophy position and ball toss creates compressive and shear forces on the lumbar discs and facet joints. Studies estimate that the serve generates forces on the lower back equivalent to approximately eight times body weight.

Spondylolysis, a stress fracture of a vertebral bone, is particularly common in young competitive players who serve frequently. Muscle strains of the paraspinal muscles and quadratus lumborum are also prevalent. Malaysian players who train outdoors in the heat may be at additional risk, as dehydration can contribute to muscle cramping and reduced spinal stability.

Core stability training, focusing on deep stabilisers like the transversus abdominis and multifidus rather than superficial muscles, is the cornerstone of back pain prevention in tennis. Adequate recovery time between training sessions and proper hydration in Malaysia's tropical climate are equally important.

Calf Strains: The "Tennis Leg"

Calf strains are so common in tennis that the injury has earned its own colloquial name: "tennis leg." This typically involves a partial tear of the medial gastrocnemius muscle, the larger of the two calf muscles, at its junction with the Achilles tendon. The injury usually occurs during a sudden push-off or sprint to the net, producing a sharp, tearing sensation in the back of the lower leg.

Players over the age of 35 are at higher risk due to age-related decreases in muscle elasticity and blood supply. The condition is often misdiagnosed as an Achilles tendon rupture, but the location of pain and a thorough clinical examination can distinguish between the two. Recovery from a moderate calf strain typically takes four to six weeks, with physiotherapy focusing on progressive loading, eccentric strengthening, and gradual return to sport-specific movements.

How Court Surface Affects Injury Risk

In Malaysia, most tennis is played on hard courts, which are the predominant surface at clubs and public facilities throughout the Klang Valley, from the National Tennis Centre in Kuala Lumpur to community courts in Subang Jaya and Petaling Jaya. Hard courts offer consistent bounce and are relatively low-maintenance for our tropical climate, but they also generate higher impact forces compared to clay or grass surfaces.

Research shows that hard court players experience higher rates of lower limb injuries, including ankle sprains, knee problems, and stress fractures, because the surface provides less shock absorption. The court's grip characteristics also affect injury patterns: surfaces that are too grippy can increase knee and ankle injuries during pivoting, while slippery surfaces raise the risk of falls and wrist sprains.

Players can mitigate surface-related injury risk by wearing court-specific shoes with adequate cushioning and lateral support, replacing shoes every 45 to 60 hours of play, and incorporating regular lower limb strengthening and flexibility work into their training schedules.
