Understanding the Knee: A Brief Anatomy Overview

The knee is the largest joint in the human body and one of the most mechanically complex. It is a modified hinge joint — capable of bending and straightening (flexion and extension) but also able to rotate slightly when flexed. This complexity is both its functional strength and its vulnerability.

The bones of the knee:

Femur (thigh bone) — the distal end forms the top of the knee joint
Tibia (shin bone) — the proximal end forms the bottom of the joint
Patella (kneecap) — a sesamoid bone embedded in the quadriceps tendon, sits in front of the joint and improves the mechanical leverage of the quad muscle

Cartilage: The articular cartilage is the smooth, glassy tissue that covers the ends of the femur and tibia at their joint surfaces. It allows the bones to glide against each other with minimal friction and distributes compressive forces. Articular cartilage is avascular (no blood supply) and has very limited capacity to repair itself once damaged — which is why articular cartilage loss (osteoarthritis) is often progressive.

The menisci: The medial and lateral menisci are C-shaped wedges of fibrocartilage sitting between the femur and tibia. They act as shock absorbers, distribute load, improve joint stability, and help lubricate the joint. Meniscal tears are among the most common knee injuries in both athletes and sedentary adults over 40.

Ligaments: Four primary ligaments stabilize the knee:

ACL (anterior cruciate ligament) — resists forward tibial translation and rotational forces
PCL (posterior cruciate ligament) — resists backward tibial translation
MCL (medial collateral ligament) — resists valgus (inward) stress
LCL (lateral collateral ligament) — resists varus (outward) stress

Tendons and bursae: The quadriceps tendon (above the patella) and patellar tendon (below the patella) transmit force from the quad muscle to the tibia. Multiple bursae (fluid-filled sacs) cushion the joint structures. Inflammation of these bursae (bursitis) is a common source of knee pain.

The joint capsule and synovium: The entire knee joint is enclosed in a fibrous capsule lined with synovial membrane. The synovium produces synovial fluid — the joint's lubricant and the primary source of nutrition for the avascular cartilage.

Understanding this anatomy matters because the treatment options for knee pain depend entirely on which structure is damaged and to what degree.

The Most Common Causes of Knee Pain

Knee Osteoarthritis

Osteoarthritis (OA) is the most common cause of chronic knee pain in adults over 50 — though it increasingly affects younger people due to prior injury, excess body weight, or genetic predisposition. OA is a degenerative joint disease characterized by:

Progressive erosion of articular cartilage
Reactive bone changes (bone spurs / osteophytes)
Synovial inflammation (secondary to cartilage debris)
Gradual joint space narrowing visible on X-ray

Symptoms: aching pain worsened by activity, morning stiffness that improves with movement, crepitus (grinding or clicking), swelling, and reduced range of motion.

Knee OA is graded on a 0–4 scale (Kellgren-Lawrence):

Grade 0: Normal
Grade 1: Possible narrowing, questionable osteophytes
Grade 2: Definite osteophytes, possible narrowing
Grade 3: Multiple moderate osteophytes, definite narrowing, mild bone deformity
Grade 4: Large osteophytes, severe narrowing, severe bone deformity

Conservative non-surgical treatment is most appropriate for grades 1–3. Grade 4 represents "bone on bone" arthritis where surgical options are more commonly considered, though some patients even at Grade 4 achieve meaningful improvement with aggressive non-surgical programs.

Meniscal Tears

The menisci are commonly injured in two distinct populations and two distinct injury patterns:

Traumatic tears occur in younger, active individuals through twisting injuries — a plant-and-pivot movement in sports, a fall, a sudden change of direction. The tear is acute, often accompanied by pain, swelling, and mechanical symptoms (locking, catching).

Degenerative tears occur in middle-aged and older adults without a specific trauma event. The meniscal tissue simply degenerates over time and tears under normal loading. These are often discovered incidentally on MRI obtained for other reasons.

The clinical significance of a meniscal tear depends on its type, location, and the patient's symptoms. Many degenerative meniscal tears are asymptomatic. For those that are symptomatic, the treatment landscape has shifted significantly in the past decade.

Patellofemoral Pain Syndrome (PFPS)

PFPS — informally called "runner's knee" — is anterior knee pain originating from the patellofemoral joint. It results from abnormal patellar tracking: the patella moves laterally out of its groove in the femur (the trochlear groove) during knee flexion, creating abnormal pressure on the lateral facet of the patella and the lateral femoral condyle.

Causes include quadriceps weakness (particularly VMO weakness), tight IT band, hip weakness, and biomechanical factors in the foot and ankle. PFPS is extremely common in runners, cyclists, and people who do a lot of stair climbing.

Patellar Tendinopathy (Jumper's Knee)

Chronic degeneration of the patellar tendon — the tendon running from the patella to the tibial tuberosity — produces anterior knee pain worsened by jumping, squatting, and stair descent. Common in basketball players, volleyball players, and people who do a lot of squatting. Shockwave therapy has strong evidence for patellar tendinopathy.

Iliotibial (IT) Band Syndrome

The IT band is a thick fascial band running from the hip to the lateral knee. When it becomes tight or inflamed, it creates lateral knee pain that worsens with repetitive knee flexion and extension — classically in runners and cyclists. Also common in pickleball players who do a lot of lateral movement.

Bursitis

Prepatellar bursitis (in front of the kneecap) and pes anserine bursitis (at the medial tibial flare) are common sources of knee pain, particularly in people who kneel frequently or have knee OA.

Ligament Sprains

MCL sprains from valgus stress, LCL sprains from varus stress, and ACL tears from pivot-landing injuries are common athletic knee injuries. Complete ACL tears typically require surgical reconstruction in active patients; partial tears and MCL/LCL sprains usually respond to conservative care.

How Knee Pain Is Diagnosed

Accurate diagnosis is the essential first step. The treatment plan depends entirely on identifying which structure is damaged.

Clinical history: When did the pain start? What were you doing? Has it improved, worsened, or plateaued? Where exactly is the pain (anterior, medial, lateral, posterior)? What makes it better or worse?

Physical examination:

Range of motion testing
Patellar tracking assessment
Ligament stability tests (Lachman, anterior/posterior drawer, varus/valgus stress)
Meniscal provocation tests (McMurray, Apley)
Palpation of specific structures
Gait analysis

Imaging:

X-ray: Best for assessing bone structure, joint space, osteophytes, fractures. The primary tool for staging OA.
MRI: Gold standard for soft tissue — menisci, ligaments, cartilage, tendons. Ordered when soft tissue injury is suspected.
Ultrasound: Useful for dynamic assessment of tendons and bursae.

At McNamara Chiropractic Center, Dr. McNamara reviews all existing imaging and provides referrals for additional studies when the diagnosis is unclear.

The Conservative Treatment Spectrum

Conservative treatment for knee pain spans a wide range of interventions. Understanding what each can and cannot accomplish helps patients make informed decisions.

RICE Protocol (Acute Phase)

For acute injuries and flare-ups: Rest, Ice, Compression, Elevation. Reduces acute inflammation in the first 24–72 hours after injury. Not a long-term treatment strategy.

Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)

Over-the-counter NSAIDs (ibuprofen, naproxen) and prescription NSAIDs reduce pain and inflammation. Useful for acute pain management. Long-term use carries GI, cardiovascular, and renal risks. NSAIDs do not halt OA progression or repair damaged tissue.

Physical Therapy and Exercise

Structured exercise therapy is one of the most evidence-supported interventions for knee OA. Strengthening the quadriceps, hamstrings, hip abductors, and hip extensors reduces the mechanical load on the knee joint and can meaningfully reduce pain. The challenge is that painful knees often inhibit the very exercise that would help — a cycle that requires guided therapeutic progression to break.

Corticosteroid Injections

Intra-articular cortisone injections reduce pain and inflammation, often providing weeks to months of relief. They do not address the underlying degeneration and repeated injections may accelerate cartilage loss. Useful for acute flare-ups and as a bridge during conservative treatment programs.

Hyaluronic Acid (Viscosupplementation) Injections

Injections of hyaluronic acid (e.g., Synvisc, Euflexxa) into the joint are intended to supplement the joint's natural synovial fluid. Evidence is mixed — some patients experience significant benefit, others minimal. Generally considered before surgical options.

Platelet-Rich Plasma (PRP) Injections

PRP uses growth factors from the patient's own blood to stimulate tissue repair. Evidence for knee OA is growing but not yet definitive. Some patients with early to moderate OA experience meaningful improvement.

Knee Bracing

Unloader braces for medial compartment OA shift mechanical load from the worn compartment to the healthier lateral compartment. Patellar bracing and taping can improve patellar tracking in PFPS. Not curative but can reduce pain and improve function.

When Surgery Is and Is Not the Answer

Surgery is not the automatic answer for knee pain, even severe pain. Understanding the indications for surgery — and the evidence around surgical outcomes — helps patients make truly informed decisions.

Knee Replacement (Total and Partial Knee Arthroplasty)

Total knee replacement (TKR) replaces all three compartments of the knee with metal and plastic components. Partial (unicompartmental) knee replacement replaces only the most damaged compartment.

When TKR is appropriate:

Severe Grade 4 OA with significant functional limitation
Failed conservative treatment after a reasonable trial (typically 3–6 months)
Pain that prevents sleep or basic daily activities
Radiographic findings consistent with the severity of reported symptoms

What TKR does not guarantee:

TKR is major surgery with a recovery of 3–6 months minimum
10–20% of patients report persistent pain after knee replacement
Implants have a lifespan of 15–20 years — younger patients face potential revision surgery
Complications include infection, blood clots, implant loosening, and nerve damage

The evidence on conservative alternatives: Multiple studies published in journals including JAMA and NEJM have found that structured conservative programs — exercise therapy, weight management, and appropriate non-surgical interventions — produce comparable pain reduction and functional improvement to surgery in patients with moderate knee OA, without surgical risks.

Meniscal Surgery (Arthroscopic Partial Meniscectomy)

One of the most common orthopedic surgeries in the US — but also one of the most studied. A landmark 2013 NEJM study (Sihvonen et al.) compared arthroscopic meniscal repair to sham surgery in patients with degenerative meniscal tears and found no statistically significant difference in outcomes at 12 months. Subsequent studies have reinforced this finding.

Current evidence suggests: For degenerative meniscal tears in the absence of mechanical symptoms (locking, catching), a structured conservative program produces equivalent outcomes to arthroscopic partial meniscectomy, with less risk.

For traumatic, complex, or root tears with mechanical symptoms in younger patients, surgical consultation remains appropriate.

ACL Reconstruction

For complete ACL tears in active patients who want to return to pivoting sports, ACL reconstruction remains the standard of care. In sedentary patients or those with low-demand activity levels, some studies suggest conservative rehabilitation produces acceptable outcomes. This is a nuanced decision made in consultation with an orthopedic surgeon.

Non-Surgical Knee Decompression: The Knee-on-Trac

The Knee-on-Trac represents a significant advance in non-surgical knee care — one that many patients with knee pain have never been offered because it is not yet standard in most clinical settings.

The device applies precisely controlled, computer-managed traction to the knee joint. The patient's leg is comfortably secured in the apparatus, and the controlled distraction separates the femoral and tibial joint surfaces — creating a negative pressure environment within the joint capsule.

What this achieves:

Mechanical decompression: Reducing intra-articular pressure provides immediate pain relief for compressed joints. The joint surfaces are briefly separated from each other, removing the bone-on-bone pressure that drives the aching pain of OA.

Improved synovial fluid dynamics: The cyclic distraction and release promotes circulation of synovial fluid throughout the joint space. Cartilage — avascular tissue with no direct blood supply — depends on synovial fluid for oxygen and nutrients. When this fluid is stagnant, cartilage dehydrates and degenerates faster. Improved fluid circulation slows this process and can support cartilage maintenance.

Reduction in joint inflammation: Decompression reduces the mechanical stimulation of inflammatory processes within the joint capsule. Combined with laser therapy, the anti-inflammatory effect is compounded.

Nerve decompression: Compressed joint structures irritate local nerve endings. Reducing intra-articular pressure also reduces this mechanical nerve irritation.

Clinical results: Many patients who undergo the Knee Restoration Program at McNamara Chiropractic Center — combining Knee-on-Trac, Class IV Laser, and Shockwave — report significant reduction in pain and improved daily function within the program course. Some patients who were scheduled for knee replacement have been able to delay or avoid surgery.

It is important to be transparent: Knee-on-Trac does not regenerate cartilage or repair complete structural tears. Patients with Grade 4 "bone on bone" OA may experience less benefit than those with Grade 2 or 3 OA. Dr. McNamara evaluates each patient individually and provides an honest prognosis before beginning treatment.

Class IV Laser Therapy for Knee Pain

Class IV laser therapy (photobiomodulation) is a core component of the Knee Restoration Program because of its well-documented anti-inflammatory and tissue-healing effects.

At power levels exceeding 500 milliwatts in the 800–1000nm near-infrared spectrum, the laser penetrates to the depth of the knee joint — reaching cartilage, synovial tissue, and periarticular structures that surface treatments cannot access.

For knee osteoarthritis: Clinical trials have demonstrated that photobiomodulation reduces pain and stiffness in knee OA patients, with some studies showing benefits maintained at 1–3 month follow-up. The mechanism includes reduced prostaglandin E2 (a key inflammatory mediator), reduced interleukin-1β, and improved mitochondrial function in chondrocytes (cartilage cells).

For patellar tendinopathy and soft tissue conditions: Laser accelerates tendon healing by stimulating fibroblast activity and collagen synthesis. Combined with shockwave therapy, it significantly shortens recovery time for chronic tendinopathies.

For post-treatment recovery: After Knee-on-Trac decompression, laser therapy to the joint reduces the residual inflammatory response and supports the healing that decompression initiates. The two modalities work synergistically rather than sequentially.

Sessions are painless — most patients feel a gentle warmth. Protective eyewear is worn during treatment. Sessions run 5–15 minutes per area.

Shockwave Therapy for Knee Conditions

Extracorporeal Shockwave Therapy (ESWT) is particularly valuable for the soft tissue components of knee pain:

Patellar tendinopathy: Multiple systematic reviews and randomized controlled trials support shockwave as an effective treatment for patellar tendinopathy, particularly chronic cases that have failed physical therapy. The angiogenic effect of ESWT is especially important here — poorly vascularized tendon tissue requires new blood vessel formation to mount a genuine healing response.

IT band syndrome: Shockwave applied to the lateral knee and distal IT band reduces chronic inflammation and trigger point activity.

Pes anserine bursitis: ESWT reduces chronic bursitis that has failed to respond to other conservative measures.

Calcific deposits: In the rare cases where calcium has deposited in periarticular knee structures, shockwave mechanically disrupts and breaks down the deposits.

In the context of the Knee Restoration Program: Shockwave is used to address the soft tissue dysfunction around the knee (tendon and bursa issues) while Knee-on-Trac addresses the joint itself and laser addresses both. The combined program treats multiple pain generators simultaneously.

The Knee Restoration Program at McNamara Chiropractic Center

The Knee Restoration Program is the clinical centerpiece of what makes McNamara Chiropractic Center different from a standard chiropractic office for knee patients.

The three-modality combination:

Knee-on-Trac — Non-surgical joint decompression
Class IV Laser Therapy — Deep tissue photobiomodulation for anti-inflammatory and regenerative effects
Shockwave Therapy (ESWT) — Acoustic wave therapy for soft tissue healing and angiogenesis

Each modality addresses a different aspect of knee pathology. Treating all three simultaneously — joint compression, tissue inflammation, and periarticular soft tissue degeneration — produces compound results that no single therapy achieves alone.

Program structure:

Initial evaluation by Dr. McNamara (history, physical exam, imaging review)
Written treatment plan with realistic goals and timeline
Sessions 2–3 times per week, typically 12–20 visits depending on presentation
Formal reassessment at visit 8–12 to evaluate progress
Discharge planning with home exercise program

Who benefits most:

Knee OA Grade 2–3 (moderate)
Chronic patellar tendinopathy
Meniscal degeneration with chronic pain
Knee pain that has failed standard chiropractic, PT, or injection therapy
Patients who want to avoid or delay knee replacement
Active adults who need to return to sport or exercise

Who may not be appropriate:

Grade 4 OA with severe bone deformity (surgery may be unavoidable)
Recent knee surgery (within 6 months) without surgical clearance
Knee infection or tumor
Severe vascular disease affecting the lower extremity

The initial evaluation is the determining factor. Dr. McNamara provides an honest assessment of candidacy and prognosis before any treatment begins.

South Florida and the Active Knee: Golf, Pickleball, and Tennis

South Florida's year-round outdoor lifestyle puts unique demands on knees. Understanding the sport-specific injury patterns helps contextualize treatment and prevention.

Golf

The golf swing is a complex multi-joint movement that loads the knee in specific ways. During the backswing, the lead knee is pushed into internal rotation and valgus loading. During the downswing and follow-through, rotational forces are transmitted through the knee. The impact phase loads the lead knee significantly.

Common golf-related knee conditions:

Medial compartment OA — from years of repetitive valgus loading at the lead knee
MCL strain
IT band syndrome (trail knee during follow-through)
Meniscal tears from the combination of loading and rotation

The Lighthouse Point area has several excellent golf courses, and our patient population includes many avid golfers who have been told to choose between golf and their knees. The Knee Restoration Program has helped many of them stay on the course.

Pickleball

Pickleball has exploded in South Florida's retirement and active adult communities. The sport's combination of lateral movement, frequent stopping and starting, and low-to-the-ground volleying is hard on knees — particularly for players who took up the sport later in life when some baseline degeneration was already present.

Common pickleball knee injuries:

Meniscal tears from lateral pivoting
Patellar tendinopathy from the "pickleball crouch" position
Knee OA flare-ups from the high-frequency activity demands
IT band syndrome from lateral movement patterns

Learn more in our article on pickleball knee injuries.

Tennis

Tennis players experience medial and lateral knee loading from the side-to-side court coverage, plus significant quadriceps and patellar tendon stress from the explosive starting and stopping of competitive play.

Common tennis knee injuries:

Patellar tendinopathy
Meniscal tears
Knee OA in long-term players
IT band syndrome

What to Expect During Treatment

Understanding the realistic arc of treatment helps patients commit to the full program and interpret their progress accurately.

Weeks 1–2: Many patients feel some improvement in the first 2–4 sessions, though this varies. The initial sessions focus on establishing baseline parameters and beginning the therapeutic cascade. Some patients experience temporary soreness after shockwave sessions — this is normal and indicates the regenerative process is active.

Weeks 3–5: The mid-program period is typically where the most consistent improvement is seen. The cumulative laser and decompression effect begins to clearly reduce baseline pain. Range of motion often improves.

Weeks 6–8: Plateau assessment. Dr. McNamara formally reassesses at this stage. Most patients who are going to respond significantly have done so by this point. Ongoing maintenance or modified programs are planned.

What good progress looks like:

Baseline pain (1–10 scale) reduced by 50% or more
Improved walking distance and stair tolerance
Return to activities (golf, pickleball, gardening) that were previously limited
Reduced reliance on pain medication
Improved sleep quality

What progress does not look like:

Complete elimination of all pain in all circumstances — this is not a realistic short-term expectation for moderate-to-severe OA
Pain relief on the first session only (acute effects are often followed by mild soreness before sustained improvement)
