Primary Hip

Primary Hip Replacement

Restore your hip. Reclaim your life.

Hip joint replacement medical imaging

Hip replacement surgery removes damaged bone and cartilage from the hip joint and replaces it with a prosthetic implant. For patients with severe arthritis or hip damage, it is one of the most effective procedures in all of medicine — with the vast majority returning to full, active lives.

When It May Be Needed

  • Persistent hip pain that limits daily activities like walking, climbing stairs, or getting up from a chair
  • Hip pain that continues at rest or wakes you at night
  • Stiffness that makes it hard to move or lift your leg
  • Little or no relief from anti-inflammatory medications, physical therapy, or walking aids

What to Expect

  • Most patients are up and walking the same day as surgery
  • Hospital stay is typically 1–2 days
  • Return to light activity within 6 weeks for most patients
  • Full recovery and return to active lifestyle in 3–6 months

Dr. Fox's Approach

Dr. Fox uses the latest implant technology and surgical techniques to minimize tissue disruption and speed recovery. Each procedure is tailored to the patient's anatomy, activity level, and goals — because no two hips are exactly alike.

Primary Knee

Primary Knee Replacement

Less pain. More movement. Better days.

Knee joint replacement medical imaging

Knee replacement surgery resurfaces the damaged ends of the bones in the knee joint with metal and plastic components, eliminating the bone-on-bone friction that causes pain. It is among the most commonly performed and most successful orthopedic procedures, with outcomes that consistently improve quality of life.

When It May Be Needed

  • Knee pain severe enough to limit walking, climbing stairs, or daily activities
  • Chronic knee swelling that does not improve with rest or medication
  • Knee deformity — bowing in or out of the leg
  • Failure to improve with conservative treatments including injections and physical therapy

What to Expect

  • Most patients begin walking with assistance the day of surgery
  • Hospital stay is typically 1–2 days
  • Driving and light activity typically resume within 4–6 weeks
  • Most patients reach full recovery within 3–6 months

Dr. Fox's Approach

Dr. Fox carefully evaluates each patient to determine the right implant type and surgical approach. He uses precise alignment techniques to ensure the new joint moves naturally and lasts as long as possible — giving patients the best chance at a pain-free, active life.

Revision Surgery

Revision Hip & Knee Replacement

Complex cases. Specialized expertise.

Surgeon reviewing joint replacement imaging with patient

Revision surgery replaces or repairs a previously implanted joint replacement that has worn out, loosened, become infected, or is causing pain. It is significantly more complex than a primary replacement — requiring advanced surgical planning, specialized implants, and a surgeon with dedicated fellowship training in revision procedures.

When It May Be Needed

  • Pain or instability in a previously replaced joint
  • Implant loosening or wear over time
  • Periprosthetic joint infection (PJI)
  • Implant fracture or mechanical failure
  • Stiffness or limited range of motion after a prior replacement

What to Expect

  • Surgery is longer and more complex than primary replacement
  • Recovery is typically longer — 6 to 12 months for full results
  • A thorough pre-operative workup is essential to plan the revision
  • Dr. Fox will walk you through every step of the process before surgery

Dr. Fox's Approach

Revision surgery is where fellowship training matters most. Dr. Fox's advanced training in complex joint reconstruction means he has the experience and technical skill to address even the most challenging revision cases — giving patients the best possible outcome when a prior replacement has failed.

Knee Arthroscopy

Knee Arthroscopy

Minimally invasive. Precisely targeted.

Knee arthroscopy minimally invasive procedure

Knee arthroscopy is a minimally invasive surgical procedure that uses a small camera (arthroscope) inserted through tiny incisions to diagnose and treat problems inside the knee joint. It allows Dr. Fox to address a range of conditions with less tissue disruption, less pain, and faster recovery than open surgery.

When It May Be Needed

  • Torn meniscus causing pain, swelling, or locking of the knee
  • Loose bodies (bone or cartilage fragments) within the joint
  • Mild to moderate cartilage damage or chondral lesions
  • Persistent knee pain or swelling not explained by imaging alone
  • Diagnostic evaluation when the source of knee pain is unclear

What to Expect

  • Procedure is typically performed as outpatient surgery
  • Most patients go home the same day
  • Return to light activity within 1–2 weeks for many patients
  • Full recovery depends on the specific procedure performed

Dr. Fox's Approach

Dr. Fox uses arthroscopy as both a diagnostic and therapeutic tool — addressing the underlying problem directly rather than managing symptoms alone. When arthroscopy reveals more advanced joint disease, he can discuss all available options, including joint replacement, in the same conversation.

Fracture Care

Fracture Care

Restoring stability. Rebuilding function.

Hip and lower extremity fracture imaging

Fractures of the hip, femur, tibia, and other lower extremity bones often require surgical stabilization to restore alignment, protect the joint, and allow early mobilization. Dr. Fox provides comprehensive fracture care with a focus on getting patients moving safely as quickly as possible — particularly important for older adults where prolonged immobility carries its own risks.

When It May Be Needed

  • Hip fractures, including femoral neck and intertrochanteric fractures
  • Periprosthetic fractures (fractures around a joint replacement)
  • Femur or tibial shaft fractures requiring surgical fixation
  • Fractures in patients with osteoporosis or metabolic bone disease

What to Expect

  • Treatment plan depends on fracture type, location, and patient health
  • Many hip fractures are treated with same-admission surgery
  • Early weight-bearing and physical therapy are prioritized when safe
  • Follow-up imaging confirms healing and guides return to activity

Dr. Fox's Approach

Dr. Fox approaches fracture care with the same attention to detail as joint replacement — selecting the right fixation strategy for each patient's anatomy, bone quality, and functional goals. For hip fractures in older adults, he coordinates closely with the medical team to optimize perioperative care and minimize complications.

General Orthopedics

General Orthopedic Care

Comprehensive care for bones, joints, and soft tissue.

Orthopedic physician reviewing musculoskeletal imaging with patient

Beyond joint replacement, Dr. Fox provides general orthopedic evaluation and management for a broad range of musculoskeletal conditions affecting the hip, knee, and lower extremity. Many patients benefit from non-surgical treatment — and when surgery is needed, having a fellowship-trained surgeon involved from the start ensures the right plan from the beginning.

When It May Be Needed

  • Hip or knee pain without a clear diagnosis
  • Bursitis, tendinitis, or soft-tissue injuries around the hip or knee
  • Osteoarthritis managed with injections, bracing, or activity modification
  • Muscle strains, ligament sprains, or overuse injuries of the lower extremity
  • Second opinion on a recommended orthopedic procedure

What to Expect

  • Thorough evaluation including history, physical exam, and imaging review
  • Conservative options discussed before any surgical recommendation
  • Coordinated care with physical therapy and primary care when appropriate
  • Clear explanation of diagnosis, prognosis, and all available treatment paths

Dr. Fox's Approach

Dr. Fox believes the best surgical outcome starts with an accurate diagnosis and a thoughtful non-operative trial when appropriate. He takes time to understand each patient's goals — whether that means returning to competitive sport, walking without pain, or simply getting through the day — and builds a plan accordingly.
