About

Dr Allison Orthopedic Oncologist LADaniel C. Allison, MD, FACS, is an internationally recognized orthopedic oncologic and advanced reconstruction surgeon and Assistant Professor and Assistant Director of Orthopedic Oncology at Cedars-Sinai Medical Center, Associate Clinical Professor at University of Southern California, and Co-Director of Orthopedic Oncology at Children’s Hospital of Los Angeles (CHLA). Partnering with Dr. Allison is a multidisciplinary team of practitioners specializing in musculoskeletal tumors and cancers, severe degenerative bone and joint disease, and complex orthopedic trauma.

Orthopedic oncology is a unique field with very few specialists making Dr. Allison one of the most sought after experts in various musculoskeletal conditions and cancers affecting these systems. His training in the treatment of complex oncologic conditions makes his exceptionally adept at handling complex non-oncologic bone and joint conditions for severe degenerative disease, trauma, or prior surgery, especially as it pertains to joint replacement. With a treatment philosophy based on caring for patients like family, Dr. Allison is dedicated to providing comprehensive, world-class care.

Multi-Disciplinary Expertise

Dr. Allison’s training and experience as an orthopedic oncologist gives him extensive knowledge of pelvic and extremity tumors of bone and soft tissue, degenerative joint disease, limb preservation, and complex trauma essential to treating extensive orthopedic conditions.


With access to some of the most medically advanced technology, Dr. Allison and his orthopedic team treat a range of orthopedic conditions, including:

  • Malignant tumors (cancers) of bone and soft tissue
  • Benign tumors of bone and soft tissue
  • Severe hip and knee joint degeneration requiring reconstruction and replacement
  • Failure or need for revision of hip and knee replacement
  • Complex pelvic and extremity trauma and fracture care
  • Complications from trauma, including malunions and non-unions
  • Peri-prosthetic (joint replacement) infection and osteomyelitis (bone infection)

Orthopedic Oncology Treatment Solutions

As with other malignancies, musculoskeletal cancers require consistent, standardized care that is also individualized to match the specific patient. Numerous factors affect the course of treatment and outcomes for these tumors, such as stage, location, subtype, grade, and size, in addition to a patient’s age and general health. In addition to following the evidence and highest standards, Los Angeles’s Dr. Allison develops a treatment plan unique to each patient recommending solutions for the best possible outcome.

Benign or malignant tumors treated by Dr. Allison include:

  • Bone Cancers – from primary bone sarcomas to metastatic bone disease
  • Soft Tissue Cancers – soft tissue sarcomas
  • Invasive Skin Cancers – melanoma, squamous cell carcinoma, and Merkel cell carcinoma

Often surgery is a recommended treatment and in these cases, Dr. Allison’s goal is to minimize the affect of surgical trauma on the body while also completely removing these life and limb threatening entities.

Complex Joint Reconstruction

Degeneration (“wear and tear”), inflammatory rheumatologic conditions (like rheumatoid arthritis, psoriatic arthritis, or lupus), fractures around the joint (acutely or chronically), avascular necrosis (bone death), congenital deformities, infection, bleeding disorders, neuropathic conditions, and metabolic disorders can all cause joint destruction with associated pain and disability. Hip and knee replacement can offer an excellent solution to these difficult problems, but these procedures require an expert with extensive reconstruction experience, especially in complex cases with extensive bone loss and deformity. Prior joint replacements can fail from loosening (loss of fixation in the bone), fracture around the implant (periprosthetic fracture), scarring of the soft tissues (arthrofibrosis), malalignment, infection, and implant failure. Dr. Allison has extensive training and expertise in the reconstruction of complex primary joint conditions and revision joint replacement surgery.

Experienced Skeletal Trauma Surgeon

Experienced Orthopedic Oncology Specialist LAAcute skeletal trauma requires immediate evaluation and treatment in order to optimize healing and recovery. Coordinating efforts with a team of trauma specialists, Dr. Allison determines the best treatment for complex and multiple extremity injuries.

Los Angeles’ Dr. Allison’s background in the treatment of destructive orthopedic tumors and extensive training at Los Angeles County General Hospital aptly qualifies him to fix bones and preserve soft tissue damaged by traumatic injuries, applying sophisticated bone and soft tissue preservation techniques. He and his surgical team efficiently treat a scope of complex orthopedic trauma, including upper and lower extremity fractures, pelvic and acetabular fractures, and hip fractures requiring joint replacement.
