About the Study

Septic arthritis is a severe and potentially life-threatening condition characterized by the invasion of joint spaces by infectious agents, leading to inflammation and destruction of articular structures. It requires prompt diagnosis and aggressive treatment to prevent irreversible joint damage and systemic complications. Surgical intervention plays a crucial role in managing septic arthritis, especially when adjacent tissues are involved.

Pathophysiology of septic arthritis

Septic arthritis typically results from hematogenous spread of bacteria, most commonly Staphylococcus aureus, into the joint space. Other pathogens such as Streptococcus species, gramnegative bacteria, and Mycobacterium tuberculosis can also cause septic arthritis, albeit less frequently. Infection may also occur secondary to direct inoculation of pathogens into the joint, such as in cases of trauma, surgery, or contiguous spread from adjacent infected tissues.

Once bacteria enter the joint space, they trigger an inflammatory response, leading to synovial membrane hypertrophy and increased production of inflammatory cytokines. Neutrophils infiltrate the joint, causing synovial fluid to become purulent. The inflammatory process leads to cartilage destruction, bone erosion, and ultimately joint destruction if not promptly treated.

Surgical considerations in septic arthritis

Joint aspiration and culture: Aspiration of the affected joint for synovial fluid analysis and culture is a crucial initial step in the management of septic arthritis. It helps confirm the diagnosis and identify the causative organism, guiding antibiotic therapy. Ultrasound or fluoroscopy guidance may be necessary for deepseated joints or obese patients to ensure accurate needle placement.

Debridement and lavage: Surgical debridement and irrigation of the infected joint are essential for removing purulent material, inflammatory mediators, and necrotic tissue. Arthroscopic or open surgical techniques may be employed depending on the joint involved and the extent of infection. Multiple debridements may be required, especially in cases of persistent infection or extensive tissue involvement.

Synovectomy: It involves the removal of the synovial membrane, which is often inflamed and serves as a reservoir for bacteria. Partial or total synovectomy may be performed depending on the extent of synovial involvement and the patient's clinical condition.

Joint stabilization: In cases where joint stability is compromised due to ligamentous or capsular involvement, surgical repair or reconstruction may be necessary to restore stability and function. This is particularly important in weight-bearing joints such as the hip and knee to prevent long-term disability.

Implant removal: If a prosthetic joint is infected, implant removal is usually necessary to eradicate the infection. This may involve one-stage or two-stage revision arthroplasty, depending on the severity of infection and the patient's overall health status.

Complications of septic arthritis and adjacent tissue involvement

Joint destruction: Delayed diagnosis or inadequate treatment can lead to irreversible joint damage, including cartilage destruction, bone erosion, and fibrosis. Joint destruction may result in chronic pain, stiffness, deformity, and functional impairment, necessitating joint replacement surgery in severe cases.

Osteomyelitis: Infection can spread from the joint into adjacent bone, resulting in osteomyelitis. Osteomyelitis may require surgical debridement, bone grafting, and long-term antibiotic therapy for resolution.

Soft tissue necrosis: Severe infection and inflammation can cause necrosis of surrounding soft tissues, leading to abscess formation and tissue breakdown. Surgical drainage of abscesses and debridement of necrotic tissue are necessary to prevent further tissue damage and systemic spread of infection.

Sepsis and systemic complications: Septic arthritis can progress to sepsis, a life-threatening condition characterized by systemic inflammation and organ dysfunction. Prompt surgical intervention and appropriate antibiotic therapy are essential to prevent the spread of infection and systemic complications such as septic shock, multi-organ failure, and death.

Chronic pain and disability: Even with successful treatment, some patients may experience chronic pain, stiffness, and functional limitations secondary to joint damage and postinflammatory changes. Physical therapy and rehabilitation may be necessary to optimize functional outcomes and improve quality of life.

Septic arthritis is a serious condition that requires prompt diagnosis and aggressive treatment to prevent irreversible joint damage and systemic complications. Surgical intervention plays a crucial role in managing septic arthritis, especially when adjacent tissues are involved. Joint aspiration, debridement, synovectomy, and joint stabilization are essential surgical procedures aimed at eradicating infection, preserving joint function, and preventing long-term disability. However, surgical management of septic arthritis is not without risks, and complications such as joint destruction, osteomyelitis, soft tissue necrosis, sepsis, and chronic pain can occur, emphasizing the importance of early recognition and intervention.
