Ahmedabad –
AP View & Lateral View
Digital X-Ray Knee for knee pain, arthritis grading, fractures, sports injuries & pre-operative planning. AP and Lateral views available — MD Radiologist reports in 30 minutes. 15 branches open 24/7.
Four Knee X-Ray Views Available
Each view reveals different structures of the knee joint. Your orthopaedic surgeon or physician will specify the view required — click each card to understand what it shows and when it is used.
AP View
Lateral View
AP + Lateral (Both)
Weight-Bearing / Stress
The AP (Antero-Posterior) knee X-ray is the most commonly requested view — the beam passes from front to back with the patient standing or lying supine. It provides a frontal image of the knee showing the medial and lateral compartments of the tibiofemoral joint, both femoral condyles, both tibial plateaus, and the fibular head. The joint space width on the AP view is the primary measurement for osteoarthritis grading (Kellgren-Lawrence classification) and is the standard for comparing serial X-rays over time.
- ✅Joint space measurement: Medial and lateral compartment joint space width — the key parameter for osteoarthritis severity (K-L grading)
- ✅Osteophytes: Marginal osteophyte formation at femoral condyles and tibial plateaus — standard K-L grading feature
- ✅Tibial plateau fractures: Medial or lateral split/depression fractures — AP is the primary view for tibial plateau fracture assessment
- ✅Varus / valgus alignment: Medial or lateral compartment narrowing indicating knee malalignment — guides surgical correction decisions
- ✅Subchondral sclerosis: Bone density increase under cartilage — a K-L grading criterion for moderate to severe osteoarthritis
The lateral knee X-ray is taken with the patient lying on their side, providing a profile view of the knee. It is the essential companion to the AP view — showing structures invisible on the front view: the patella and its relation to the femur (patellofemoral joint), the popliteal soft tissues, the suprapatellar pouch for effusion, the posterior femoral condyles, and the tibial slope. Most significantly, joint effusion (water on the knee) is visible on the lateral view as a suprapatellar soft-tissue shadow — and cannot be reliably seen on AP view.
- ✅Knee effusion: Suprapatellar pouch fluid (fat pad sign, sail sign) — joint swelling/water on the knee is best seen on lateral
- ✅Patella position: Patella alta (high-riding patella) or patella baja (low patella) — assessed using Insall-Salvati ratio on lateral view
- ✅Posterior condyle fractures: Posterior cortex of femoral condyles, distal femur fracture extension — invisible on AP, clearly seen on lateral
- ✅Patellofemoral arthritis: Joint space between the patella and femoral trochlea — a separate compartment assessed only on the lateral view
- ✅Hoffa's fat pad: Infrapatellar fat pad inflammation and calcification — a common cause of anterior knee pain visible only on lateral
The combined AP + Lateral knee X-ray is the standard complete knee study prescribed for most orthopaedic evaluations. Together, the two views provide full 360-degree assessment of the knee joint — the AP view for joint space and tibiofemoral alignment, and the lateral for patellofemoral assessment, effusion, and posterior structures. Most orthopaedic surgeons require both views before any knee surgery, and both are needed for complete arthritis staging and trauma evaluation.
- ✅Complete joint assessment: All three knee compartments — medial TF, lateral TF, and patellofemoral — evaluated across both views
- ✅Pre-operative standard: Orthopaedic surgeons require AP + Lateral before TKR, arthroscopy, ACL reconstruction, or tibial osteotomy
- ✅Trauma evaluation: AP identifies fracture type; lateral confirms posterior extension and displacement — both needed for fracture management
- ✅Best value: Combined AP + Lateral from ₹350 — cheaper than two separate bookings and processed as one study with one joint report
- ✅Complete documentation: For medicolegal, insurance, and disability assessment, AP + Lateral together constitute a complete knee radiographic study
A weight-bearing (standing) knee X-ray is taken with the patient standing on both feet — applying the full body weight across the knee joint. This is the most accurate method of assessing true functional joint space narrowing for osteoarthritis grading. When lying down, the cartilage decompresses and the joint space appears wider than in real life — often masking significant cartilage loss. Weight-bearing AP is the recommended standard before total knee replacement (TKR) surgery for accurate K-L grading and tibial implant size planning.
- ✅True joint space measurement: Standing load compresses thinned cartilage — reveals actual functional joint space that supine AP underestimates
- ✅Pre-TKR mandatory: Most orthopaedic surgeons require standing AP before total knee replacement for accurate compartment assessment and implant planning
- ✅Bilateral comparison: Both knees can be imaged in the same standing X-ray — allows direct left vs right comparison and assessment of overall limb alignment
- ✅Mechanical axis planning: Full-length weight-bearing leg alignment X-ray (hip to ankle) can be added when varus/valgus deformity correction is planned
- ✅Most clinically accurate K-L grading: Kellgren-Lawrence grade is significantly more accurate on standing vs supine AP — particularly for K-L Grade 2 and 3 differentiation

What is an X-Ray Knee?
A rapid, low-cost investigation using controlled X-ray beams to produce shadow images of the knee joint — revealing bones, joint spaces, and indirectly the cartilage and soft tissues.
What Knee X-Ray Shows
A knee X-ray evaluates the distal femur (lower femur, including medial and lateral condyles), the proximal tibia (tibial plateaus and intercondylar eminences), the fibular head, and the patella. The joint space between femur and tibia reflects cartilage thickness — narrowing indicates cartilage loss from arthritis. The patellofemoral joint is seen on lateral view. Soft tissue structures like the quadriceps tendon and fat pads provide indirect information about effusion and inflammation.
Digital X-Ray vs Film X-Ray
Our Digital Radiography (DR) knee X-ray systems produce sharper, higher-resolution images than older film or computed radiography (CR) systems — with 40–60% less radiation. The digital image is instantly available on a high-resolution monitor for radiologist review, with adjustable brightness and contrast to separately optimise bone and soft-tissue detail. The result: better arthritis grading, more reliable fracture detection, and faster report turnaround.
X-Ray vs MRI for Knee
Knee X-ray is the first-line investigation and shows bony pathology clearly — arthritis severity, fractures, alignment, and indirect soft-tissue changes. MRI Knee provides far greater detail for soft-tissue pathology — ACL/PCL tears, meniscal tears, chondral defects, bone marrow oedema, and Baker's cyst. The standard sequence is: X-ray first to assess joint space and rule out fracture, then MRI if ligament/meniscal injury or unexplained persistent pain is suspected.
Radiation Safety
A knee X-ray involves approximately 0.01 mSv — one of the lowest radiation doses in all of medical imaging. Equivalent to about 1 day of natural background radiation. Completely safe for adults and appropriate-age children. The knee is distant from the gonads and sensitive organs — radiation risk is minimal even for serial follow-up studies. Lead aprons are provided as standard precaution. Generally safe in all trimesters of pregnancy with abdominal shielding.
Every Knee Structure X-Ray Reads
Systematic evaluation of every bony and joint structure around the knee — as assessed by our MD Radiologists on every study.
Femoral Condyles
The distal femur — the most important bone for knee arthritis and fracture assessment.
- Medial condyle osteophytes (K-L grading)
- Lateral condyle osteophytes
- Distal femur fractures
- Avascular necrosis of medial condyle
- Bone tumours (giant cell tumour)
- Subchondral sclerosis & cysts
Tibial Plateaus
The flat tops of the tibia — site of the most common knee fractures after falls.
- Tibial plateau fractures (split/depression)
- Medial compartment narrowing (OA)
- Lateral compartment narrowing (OA)
- Tibial osteophytes — marginal spurs
- Tibial plateau slope assessment
- Intercondylar eminence (spine) fractures
Joint Space
The radiographic joint space — reflecting cartilage thickness, the cornerstone of arthritis grading.
- Medial JSW (Joint Space Width) measurement
- Lateral JSW measurement
- Asymmetric narrowing (varus/valgus)
- Complete joint space loss (bone-on-bone)
- Kellgren-Lawrence grade (0–4)
- Chondrocalcinosis (calcium in cartilage)
Patella
The kneecap — assessed for position, fracture, and patellofemoral arthritis on lateral view.
- Patellar fracture (bipartite vs fracture)
- Patella alta / baja (Insall-Salvati ratio)
- Patellofemoral joint space (lateral view)
- Patellar osteophytes — patellofemoral OA
- Patellar skyline view (axial) — for subluxation
- Dorsal patellar defect
Soft Tissues & Fat Pads
Indirect soft-tissue signs visible on X-ray — effusion, tendon calcification, and fat pad displacement.
- Suprapatellar effusion (lateral view sail sign)
- Hoffa's fat pad impingement / calcification
- Pre-patellar bursitis
- Loose bodies (calcified) in joint
- Soft tissue calcification (myositis ossificans)
- Popliteal soft tissue mass (Baker's cyst)
Post-Surgical & Implants
For operated knees — assessing implant position, loosening, and complications after TKR or other surgery.
- TKR component alignment and position
- Implant loosening (periprosthetic lucency)
- Polyethylene wear assessment
- Periprosthetic fracture
- Hardware position (screws, plates)
- Patella resurfacing component assessment
Kellgren-Lawrence Arthritis Grading — Explained
Every knee X-ray report from Usmanpura Imaging includes a Kellgren-Lawrence (K-L) grade — the international standard for osteoarthritis severity. Here's what each grade means for your knee.
Common Knee X-Ray Findings Explained
Your radiologist evaluates all these features systematically on every knee X-ray report at Usmanpura Imaging Centre.
Osteophytes
Bony spurs at joint margins — the most visible sign of osteoarthritis. "Lipping" seen at femoral condyles and tibial plateaus on AP view.
Joint Space Narrowing
Reduced space between femur and tibia — indicates cartilage loss. Medial narrowing causes varus (bow-leg), lateral causes valgus (knock-knee).
Subchondral Sclerosis
Increased bone density under the cartilage — appears as a white line on X-ray. Indicates bone remodelling from abnormal load distribution.
Subchondral Cysts
Small round lucent areas (holes) in the bone near the joint — formed by synovial fluid forced into bone. Indicate advanced cartilage loss.
Joint Effusion
Fluid in the suprapatellar pouch on lateral view — "sail sign" or "fat pad sign". Indicates active inflammation, injury, or infection.
Fractures
Tibial plateau fractures (split or depression after fall), distal femur fractures, patellar fractures — require urgent orthopaedic attention.
Loose Bodies
Calcified fragments floating in the joint — from osteochondritis dissecans or fragmented osteophytes. Cause locking/catching symptoms.
Chondrocalcinosis
Calcium deposits in the meniscal cartilage — seen as a white line parallel to the joint surface. Indicates pseudogout (CPPD disease).
AVN / Osteonecrosis
Crescent sign and subchondral collapse in medial femoral condyle — avascular necrosis from steroid use, alcohol, or idiopathic causes.
Varus / Valgus Deformity
Tibiofemoral angle deviation — varus (bow-leg) from medial OA, valgus (knock-knee) from lateral compartment disease. Measured on AP view.
Patella Alta / Baja
High-riding (alta) or low-riding (baja) patella on lateral view — assessed by Insall-Salvati ratio. Associated with instability and patellar tendon abnormalities.
Post-TKR Assessment
Component alignment, cement mantle, and periprosthetic lucency after total knee replacement — serial X-rays detect early loosening before clinical symptoms.

Benefits of Digital X-Ray Knee
Why the X-ray knee remains the essential first-line investigation for all knee conditions — fast, affordable, and informative for most clinical decisions.
Fastest Knee Imaging
Digital knee X-ray takes seconds and delivers a specialist report in 30 minutes — far faster than MRI. Walk in, walk out, same-day decision-making.
Most Affordable
Knee X-ray is 10–20 times cheaper than MRI while answering the most common clinical question: is this knee arthritis and how severe? Guides 80% of orthopaedic consultations.
Standardised K-L Grading
Kellgren-Lawrence grade on your X-ray report is the internationally accepted standard for osteoarthritis staging — used for treatment decisions, insurance approvals, disability assessment, and TKR indication.
Essential Before MRI
Knee X-ray must be done before MRI to rule out fractures, assess alignment, and give the MRI radiologist context. Many significant bony findings are better seen on X-ray than MRI.
How to Prepare for X-Ray Knee
X-Ray Knee is the simplest investigation — almost zero preparation needed. Just follow these quick guidelines.
Do's – Before Your Knee X-Ray
- ✓Walk in at any time — no appointment or fasting required for knee X-ray
- ✓Bring your doctor's prescription or referral if available (not mandatory for emergency cases)
- ✓Inform staff if you have knee implants, screws, plates, or any previous knee surgery
- ✓Wear loose-fitting trousers that can be rolled up above the knee, or change into a gown
- ✓Tell us if you are pregnant — lead shielding will be provided as a standard precaution
- ✓For weight-bearing X-ray: wear comfortable footwear you can stand in steadily for 30 seconds
- ✓Bring previous knee X-rays or MRI reports if available — comparison helps the radiologist identify changes over time
- ✓If the knee is very painful, inform staff — positioning will be adjusted for your comfort
Don'ts – What to Avoid
- ✗Do NOT wear jeans, tight trousers, or clothing with metal rivets or zips over the knee — creates X-ray artefacts
- ✗Avoid keeping keys, coins, or mobile phones in your trouser pockets near the knee during the X-ray
- ✗Do not wear thick bandages or plaster of Paris over the knee without telling staff
- ✗Do NOT move during the 1-second X-ray exposure — movement blurs the image and may require a repeat
- ✗Avoid applying pain relief patches or creams with metallic elements over the knee before X-ray
- ✗Do not delay an emergency knee X-ray after trauma — come in immediately for suspected fracture
- ✗Avoid unnecessary bilateral knee X-rays when only one knee has symptoms
- ✗Do not request an MRI before getting a knee X-ray — X-ray is always done first in standard orthopaedic practice
What Happens During
Your X-Ray Knee?
The entire knee X-ray process — from registration to report — takes under 40 minutes.
Registration (2 minutes)
Present your prescription at the counter. Staff prepares your X-ray form specifying the view and side. No queue — knee X-rays are processed with direct priority at all branches.
Change & Position Preparation (3 minutes)
Roll up trouser leg above the knee, or change into a gown if needed. Remove any bandages or knee supports as instructed. Lead apron is placed over the reproductive area as a standard radiation precaution.
AP View Positioning (2 minutes)
For AP view: lie on the X-ray table with your knee fully extended, toes pointing straight upward, and the knee placed flat against the detector. For weight-bearing: you stand in front of the wall-mounted detector.
The X-Ray (1 second each)
AP and Lateral views each take 0.5–1 second. Hold still while the exposure is taken. The image appears on the digital screen instantly. Both views are checked for quality before you leave the room.
Report in 30 Minutes
Our MD Radiologist systematically reviews the joint space, osteophytes, subchondral changes, bones, and soft tissues — assigns a K-L grade and issues a structured report. Delivered via WhatsApp and email within 30 minutes.
Why Standing X-Ray Gives a More Accurate K-L Grade
When you lie down for a knee X-ray, the cartilage decompresses under reduced load — the joint space appears wider than it really is during daily activities. In moderate osteoarthritis (K-L Grade 2–3), a lying-down AP can appear nearly normal while a standing AP reveals significant narrowing. This is critical before total knee replacement — the surgeon needs the true, weight-bearing joint space to choose the correct implant and decide on bilateral vs unilateral surgery. We recommend weight-bearing AP for all patients being considered for TKR or osteotomy.
When X-Ray Is Normal but Knee Hurts — What Next?
A normal knee X-ray does not rule out all knee pathology. The most common causes of knee pain with a normal X-ray: ACL/PCL tears, meniscal tears, chondral defects, and bone marrow oedema — all of which require MRI for diagnosis. If your knee X-ray is normal but you have significant pain, swelling, locking, or giving-way episodes after a sports injury or trauma, your orthopaedic surgeon will request an MRI Knee. Our centre offers MRI Knee studies — ask our team at any branch.

What Our Patients Say
Trusted by orthopaedic surgeons, sports doctors, and patients across Ahmedabad for accurate digital knee X-ray reporting.
I had bilateral knee pain and my orthopaedic surgeon needed weight-bearing AP knee X-rays before discussing TKR. The Satellite branch did both knees in the standing position — the report clearly showed Grade 4 OA in the left knee and Grade 3 in the right, with specific joint space measurements. My surgeon said it was the best quality knee X-ray report he had seen from a diagnostic centre. Excellent!
I twisted my knee during cricket and walked in at the Naroda branch at 10pm. The AP + Lateral knee X-ray took just 5 minutes and the report was on WhatsApp in 25 minutes — confirming no fracture, but showing a joint effusion on the lateral view. My doctor could rule out fracture immediately and proceed to MRI the next day. The 24/7 service at ₹350 for both views is incredible value!
Annual knee X-ray monitoring for my rheumatoid arthritis — the Bapunagar branch staff always positions me correctly and the radiologist report clearly notes changes in joint space from my previous year's X-ray. The most affordable and comprehensive orthopaedic X-ray service in Ahmedabad!
