Dr Adel Tavakkolizadeh, Consultant Orthopaedic & Upper Limb Surgeon at The Blackheath Hospital, explains that the most common causes of joint pain and injuries related to sports and physical activity that make people see a GP are:
- Back pain and injuries
- Knee pain and injuries
- Shoulder-related pain and injuries
Back injuries
Most of the time, these occur due to poor lifting technique or suddenly lifting heavy weights despite not being in good overall physical shape. Sometimes, back injuries can result from a traumatic incident like a motorbike accident.
“Most [cases of] back pain are generally soft tissue related and just need application of good technique, good regular exercise, and gradual buildup to ease it off,” explains Dr Tavakkolizadeh.
Knee injuries
“Knee soft tissue injuries are incredibly common,” explains Dr Tavakkolizadeh, “and at the top of the list is anterior cruciate ligament (ACL) injury.”
What is the ACL?
The ACL is a ligament that runs diagonally inside the knee joint. The two bones that make up the knee joint are the tibia, or the lower leg bone, and the femur or the thigh bone. The ACL stops the tibia from slipping in front of the femur and enables the knee to rotate safely and with stability.
In other words, this ligament controls rotation and the forward movement of the shinbone.
What is an ACL injury?
“ACL injuries generally happen with pivoting-type sports — sports where you are suddenly changing direction — and that’s why it’s very common in basketball, football, racquet sports, and it’s very common in younger age groups,” explains Dr Tavakkolizadeh.
Symptoms of an ACL injury include:
- A popping sound or sensation when the injury happens
- Swelling
- Pain
- Inability to bear weight on the leg or move the leg/knee fully
- Knee instability
The pain and swelling may go away on their own in the first 24 hours to a few weeks, explains Dr Tavakkolizadeh. However, if you return to sports, your knee will likely continue to be unstable, and you may cause further damage. This happens because “unfortunately when a ligament is torn, it remains torn.”
Surgical intervention may ultimately be necessary. “Surgery can make the knee more stable, [...] improve symptoms and function, and get people back to a normal level of sporting activity,” he says.
Injuries to other ligaments
In addition to the ACL, there are three other ligaments in the knee that can sustain a sports-related injury:
- The posterior cruciate ligament (PCL) is in the centre of the knee. It controls the backward movement of the shin bone. The PCL tends to get injured in sudden direct blows, such as in a car accident or during a soccer tackle.
- The medial collateral ligament (MCL) stabilises the inner knee.
- The lateral collateral ligament (LCL) stabilises the outer knee. Injuries here tend to occur due to sudden direct impact on the outer side of the knee, like, for example, in hockey or soccer.
Meniscus injuries
The meniscus is a small piece of cartilage between the tibia (shinbone) and the thigh bone. It is shaped like a crescent moon, or like the letter ‘C’, and it acts as a shock absorber — protecting the lower leg from the shock of your body weight.
Meniscal tears tend to occur when an athlete twists or turns their leg. Common symptoms of a meniscus tear include:
- Pain inside the knee joint, outside of it, or at the back of the knee
- Swelling
- A catching or locking sensation in the knee
- Inability to fully extend or fully bend the knee
- Limping
“Many meniscus injuries can settle by themselves and don’t require intervention,” explains Dr Tavakkolizadeh. But if the pain persists and does not get better with time, physiotherapy, and rehabilitation, you may need further intervention.
“A general advice is that if a knee has had a significant injury where there is a clear, traumatic episode, which is immediately followed by significant swelling and pain, and if it really causes restriction of movement and mobility — they should be reviewed by someone in the early stages: by a physio or a GP.”
Other lower limb injuries
Other common lower limb injuries that can require surgery may occur in the hip, ankles, or spine. They include:
- Hip impingement
- Achilles tendinopathy
- Lateral ankle ligament sprains
- Ankle osteochondral lesions
- Disc herniation and disc degeneration disease
Injuries around the foot and ankle are very common, Dr Tavakkolizadeh explains. The main issue here tends to do with overuse. “During a lot of running, you can get issues around plantar fasciitis, which is a pain in the sole of the foot, and you can get issues with pain in the tendons around the ankle such as the Achilles tendon, which is common in runners.”
Ligament sprains around the ankle are also frequent, the doctor adds, particularly in the case of people who were not active for an extended period and started overdoing the exercise. This increases the risk of sustained stress fractures in the lower limbs.
Ankle sprains make up 40% of all athletic injuries in professional athletes.
Shoulder injuries
“In the younger age group,” Dr Tavakkolizadeh says, “the classic injuries we see are shoulder instability or dislocations, which are pretty common after contact sports, such as rugby.”
These injuries “disrupt some of the important internal structures within the joints, very similar to the cruciate ligament problems in the knee. And unfortunately, once those structures are damaged, they don't tend to repair themselves naturally.”
“That's why, statistically, once you dislocate your shoulder once, you are more likely to continue having further dislocations in the future,” Dr Tavakkolizadeh adds. “And that partly depends on the sport you do and how old you are when this happens.”
Rotator cuff injury
Most commonly, a group of tendons around the shoulder — called rotator cuff tendons — can get injured due to a traumatic episode. Normally, your rotator cuff enables you to lift your arms all the way up. But accidents such as falling suddenly on your outstretched hand may injure these tendons.
Common symptoms of rotator cuff injury include:
- Persistent pain
- Pain at night
- Crackling sounds when moving your arm
- Limited mobility in the arm
- Weakness in the shoulder
Other upper limb injuries
Other common injuries of the upper limbs, explains Dr Tavakkolizadeh, include wrist and hand injuries that also tend to occur when you fall on your outstretched hand.
“You can sustain a fracture around the wrist or one of the little bones around the wrist such as the scaphoid bone, typically in sports that involve a lot of falling — rollerblading, skateboarding, skiing, snowboarding.”
If there is immediate pain and discomfort, Dr Tavakkolizadeh cautions, you may need an x-ray.
