Knee Pain in Birmingham
Causes, symptoms, and when to see a knee specialist.
Mr Shakir Hussain, Consultant Knee Surgeon at the Royal Orthopaedic Hospital Birmingham, provides expert assessment and treatment for adults with persistent knee pain across Birmingham and the West Midlands.
What is causing my knee pain?
Knee pain in adults has five common explanations: knee osteoarthritis, patellofemoral (kneecap) pain or arthritis, meniscal (cartilage) tears, ligament injuries such as the ACL or MCL, and inflammatory or referred pain from the hip or lower back. The location of the pain, the activities that provoke it, and whether mechanical symptoms (clicking, locking, giving way) are present help identify which structure is involved.
The knee is the largest weight-bearing joint in the body. It is formed where the femur (thigh bone), tibia (shin bone), and patella (kneecap) meet, cushioned by two C-shaped menisci and stabilised by four main ligaments. Because so many structures share a small space, knee pain can arise from the joint surface itself, the cartilage, the ligaments, the kneecap, or be referred from the hip or spine.
Identifying the right cause matters because the treatments differ. Knee osteoarthritis eventually requires joint replacement; meniscal and ligament problems sometimes settle with rehabilitation and sometimes need surgical attention; patellofemoral pain usually responds to targeted physiotherapy; and referred pain is treated at its source rather than the knee. A careful clinical assessment combined with a weight-bearing knee X-ray identifies the cause in the majority of cases.
Where the pain sits, and what brings it on, is the single most useful clue. Pain on the inner side of the knee that is worse on walking and stairs usually reflects osteoarthritis. Pain at the front of the knee, worse on stairs and after sitting, usually comes from the kneecap. Pain along the joint line with catching or locking suggests a meniscal tear, and a knee that gives way after an injury suggests a ligament problem.
What does your knee pain feel like?
The pattern of knee pain points strongly to the cause. Pain on the inner side of the knee that worsens on walking and stairs suggests arthritis. Pain at the front of the knee, worse on stairs and after sitting, suggests a kneecap problem. Catching, locking, or pain along the joint line suggests a meniscal tear. A knee that gives way or swells after an injury suggests a ligament problem. Pain that wakes you at night signals significant joint damage and warrants specialist assessment.
The patterns below are the ones that come up most often in clinic. They are not diagnostic on their own, but they help direct examination and imaging.
Inner-knee pain on walking and stairs
The most reliable indicator of joint surface wear. Worse on getting up from a chair, walking on uneven ground, and climbing stairs, often with swelling after activity. The most common cause in adults over 50 is knee arthritis.
Pain at the front of the knee
Aching behind or around the kneecap, worse going up and down stairs, kneeling, squatting, and after sitting for long periods (the "cinema sign"). Typical of patellofemoral pain and arthritis.
Catching, locking, or giving way
A sensation of the knee catching, locking, or briefly giving way, often with pain along the joint line. Usually points to a meniscal or cartilage tear, or a loose fragment within the joint.
Knee pain that wakes you at night
One of the strongest indicators of significant joint damage. Inflammation accumulates at rest, and even the weight of the duvet can be enough to wake you. Common in advanced knee arthritis, inflammatory arthritis, and avascular necrosis of the knee.
Stiffness in the morning
Morning stiffness lasting less than 30 minutes is typical of osteoarthritis. Stiffness lasting more than an hour, particularly with several joints affected, raises suspicion of inflammatory arthritis such as rheumatoid arthritis.
Instability or swelling after an injury
A knee that swells quickly after a twist or impact, then feels unstable or gives way, suggests a ligament injury. The pattern is typical of an ACL injury or other knee ligament injury, and warrants assessment.
When should I see a specialist about knee pain?
Knee pain that disturbs your sleep, causes a limp, limits how far you can walk, makes stairs difficult, or has not improved after six weeks of rest, physiotherapy, and anti-inflammatory medication should be assessed by a knee specialist. A hot, swollen knee with fever, the inability to bear weight after an injury, or a knee that locks and cannot be straightened needs urgent assessment in A&E, not a routine outpatient consultation.
Urgent (A&E) red flags
- A hot, red, swollen knee with fever or feeling generally unwell may indicate joint infection (septic arthritis), which is a surgical emergency.
- Severe knee pain and inability to bear weight after a fall or injury may indicate a fracture or major ligament rupture and requires urgent X-ray.
- A knee that is locked and cannot be fully straightened suggests a displaced meniscal tear or a loose fragment trapped in the joint.
- Sudden swelling with bruising immediately after a twisting injury can indicate an ACL rupture or fracture and should be assessed promptly.
- Calf pain, swelling, warmth, or breathlessness alongside knee symptoms can signal a blood clot (DVT) and needs urgent medical review.
Outside of these urgent situations, knee pain can usually be assessed in an unhurried outpatient consultation. The right time to book a specialist appointment is when the pain is changing your daily life, your sleep, or your ability to do the things you value, and conservative measures have not helped over a reasonable period.
Reasons to book a specialist knee consultation include: pain that has been present for more than six weeks; pain that wakes you at night; recurrent swelling after activity; a developing limp; difficulty with stairs, kneeling, or getting in and out of a car; pain that is reducing the distance you can walk; or a previous diagnosis of arthritis, a cartilage tear, or a ligament injury that is now getting worse.
Common causes of knee pain in adults
The conditions below account for the great majority of persistent knee pain in adults. Each is covered in more detail on its own page, with symptoms, diagnosis, conservative treatment, and the point at which knee replacement surgery in Birmingham, including robotic-assisted and partial knee replacement, becomes the right step.
Knee osteoarthritis
The most common cause of persistent knee pain over 50. Cartilage wears down over years, most often in the inner (medial) compartment, causing pain on walking and stairs, swelling, stiffness, and a gradual loss of movement. End-stage arthritis is treated with knee replacement.
Knee arthritis: symptoms, causes, and treatmentPatellofemoral pain & arthritis
Pain arising from the kneecap joint, felt at the front of the knee and worse on stairs, kneeling, squatting, and after prolonged sitting. Ranges from soft-tissue overload in younger adults to established patellofemoral arthritis in later life.
Patellofemoral arthritis: symptoms and treatmentMeniscal & cartilage tears
A tear of the C-shaped meniscus or the joint cartilage causes pain along the joint line, swelling, and mechanical symptoms such as catching or locking. Degenerate tears in older knees often coexist with early arthritis.
Knee cartilage damage: assessment and treatmentLigament injuries (ACL, MCL)
A twist or impact can sprain or rupture the knee ligaments, causing rapid swelling, instability, and a knee that gives way. The anterior cruciate ligament (ACL) and medial collateral ligament (MCL) are most commonly affected.
ACL injury: symptoms, diagnosis, and treatmentAvascular necrosis (AVN)
The blood supply to a region of bone within the knee is interrupted, leading to bone death and sudden, often severe pain, frequently worse at night. Linked to steroid use, alcohol, and some medical conditions, and can progress to joint collapse.
Knee avascular necrosis: diagnosis and treatmentInflammatory arthritis
Rheumatoid arthritis and related conditions cause knee pain with prolonged morning stiffness, warmth, and swelling, often affecting several joints. Suggested by stiffness lasting over an hour, multi-joint involvement, or unexplained tiredness and weight loss.
Rheumatoid arthritis of the knee: treatment optionsPost-traumatic arthritis
Knee pain following an old fracture, ligament injury, or meniscal surgery. The damaged joint surface wears prematurely, often becoming symptomatic years or decades after the original injury.
Post-traumatic knee arthritis: assessment and treatmentPain from a previous knee replacement
Pain, stiffness, swelling, or instability in a knee that has already been replaced can indicate loosening, wear, or infection. These problems are assessed carefully and may require revision knee surgery.
Failed knee replacement: causes and revision optionsWhat to expect at your knee consultation
A first knee consultation usually takes 30 to 45 minutes. It combines a focused history (pain pattern, activities affected, prior treatment), a clinical examination (gait, alignment, swelling, range of motion, and specific tests for the ligaments, meniscus, and kneecap), and same-visit imaging where required. Most patients leave the consultation with a clear diagnosis and a written treatment plan.
History. Mr Hussain will ask about the character and location of the pain, what makes it better or worse, how it affects walking distance, stairs, kneeling, and sleep. Previous physiotherapy, injections, scans, injuries, and any family history of joint problems are all relevant.
Examination. Standing alignment and gait are observed, and the knee is checked for swelling and range of motion. Specific tests are used for the ligaments (such as the Lachman and anterior drawer tests for the ACL), the meniscus (such as McMurray's test), and the kneecap. The hip is examined briefly when referred pain is suspected.
Imaging. A weight-bearing knee X-ray is the single most useful investigation for knee pain in adults. It shows joint space loss in arthritis, alignment, and bony changes. MRI is reserved for cases where soft-tissue pathology is suspected, such as meniscal tears, ligament injuries, or early avascular necrosis. Mr Hussain organises imaging at the time of consultation where required, with reports available within 24 to 48 hours.
Treatment plan. The vast majority of patients seen for knee pain do not require surgery. A typical plan covers activity modification, physiotherapy referral, weight management where relevant, anti-inflammatory medication, and, where appropriate, a guided joint injection. Surgical options are discussed openly when joint damage has reached the point where conservative measures are no longer sufficient.
How is knee pain treated?
First-line treatment for almost all causes of knee pain is non-surgical: weight optimisation, physiotherapy, low-impact exercise, and short courses of anti-inflammatory medication. Surgery is reserved for end-stage joint damage that no longer responds to these measures. The two definitive surgical options for the worn knee are total knee replacement, increasingly performed with robotic assistance, and, in carefully selected patients, partial (unicompartmental) knee replacement.
Conservative measures are the right starting point for almost everyone. They include physiotherapy focused on the quadriceps and hip muscles, weight loss where relevant (every kilogram lost reduces knee joint loading by roughly four kilograms during walking), low-impact aerobic exercise such as swimming or cycling, short courses of paracetamol and anti-inflammatory medication where safe, and occasionally a guided steroid injection into the joint. Many patients with early-to-moderate knee pain improve significantly with structured conservative treatment.
Surgery becomes the right step when joint damage is structural and no longer responds to conservative measures. The two definitive surgical treatments for the worn or damaged knee are described below.
Robotic Total Knee Replacement
The worn joint surfaces are replaced with a precisely aligned metal and polyethylene implant. Mr Hussain uses robotic assistance (MAKO, ROSA, and CORI) to plan and position the implant accurately, which can improve alignment and soft-tissue balance.
- Suitable for most adults with end-stage knee arthritis
- Robotic planning for accurate alignment and balance
- Most patients walk with support within 24 hours
- Return to driving at around six weeks
Partial Knee Replacement
When arthritis affects only one compartment of the knee, just the damaged part is resurfaced and the healthy ligaments and cartilage are preserved. A bone-conserving option that often allows a faster recovery and a more natural-feeling knee.
- Suitable when wear is limited to one compartment
- Preserves healthy bone, cartilage, and ligaments
- Often a quicker recovery than total replacement
- Frequently performed with robotic assistance
