About Daniel Allison

Daniel C. Allison MD, FACS, and his team base their treatment philosophy on caring for patients like family. If you have an advanced orthopedic condition, ranging from a bone or soft tissue tumor to a complex degenerative joint disorder to extensive skeletal trauma to a severe orthopedic complication, an experienced surgical team with training and expertise in advanced musculoskeletal reconstruction can make all the difference.Because of the relative rarity of these conditions, there are a limited number of surgeons like Dr. Allison in the country.

We provide advanced orthopedic procedures for musculoskeletal tumors, including Soft Tissue and Bone Sarcomas and Metaststatic Bone Disease, as well as benign bone and soft tissue growths. Some of the cancers that we treat most often are osteosarcoma, Ewing’s sarcoma, chondrosarcoma, and soft tissue sarcomas, which require comprehensive, multidisciplinary care, including surgical treatment from an expert with specialized oncologic training, like Dr. Allison.

We provide specialized procedures to remove tumors and reconstruct bones, joints, and soft tissues to help eliminate disease and restore function, using minimally invasive and advanced surgical techniques. These techniques can also readily reconstruct bone and joint structures damaged by non-tumor conditions like arthritis, fractures, trauma, avascular necrosis, infection, and other severe destructive and degenerative disorders.

Multi-disciplinary Expertise

Dr. Allison’s training and experience as an orthopedic oncology and advanced reconstruction specialist gives him extensive knowledge of complex pelvic and extremity disorders of bone and soft tissue, including tumors, degenerative joint disease, and complex trauma, orthopedic complications, and more, which is critical when treating extensive orthopedic conditions.

With with expertise in and access to some of the most medically advanced procedures and technology, Dr. Allison and his orthopedic team treat a range of orthopedic conditions,


  • 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)
  • Limbs at risk for loss or amputation
  • Orthopedic complications

Oncology Surgery: Orthopedic Oncology Treatment Solutions in Los Angeles

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 comprehensive, multi-disciplinary solutions for the best possible outcome.

Benign or malignant tumors treated by Dr. Allison include:

Bone Cancers – from primary bone sarcomas (osteosarcoma, chondrosarcoma, Ewing’s sarcoma) to metastatic bone disease (from breast cancer, prostate cancer, lung cancer, and other carcinomas)
Soft Tissue Cancers – soft tissue sarcomas (pleomorphic sarcoma, liposarcoma, synovial sarcoma)
Invasive Skin Cancers – melanoma, squamous cell carcinoma, and Merkel cell carcinoma

Oncology Surgery: 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 severe pain and disability.

Hip, knee, and shoulder 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 wear or fatigue. Dr. Allison has extensive training and expertise in the reconstruction of complex primary joint conditions and revision joint replacement that allows him to handle any joint replacement scenario.

Oncology Surgery: Experienced Skeletal Trauma Surgeon

More Information

Acute 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 and pelvic 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 tissues 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 long bone fractures, pelvic and acetabular fractures, and hip fractures requiring joint replacement.
