Septic arthritis is an acute purulent inflammation of the joints caused by infective agents like staphylococcus or streptococcus. Infection can reach joints through wounds, blood vessels, or lymph channels. Symptoms include high fever, rapid pulse, and severe pain; physical signs show marked swelling, redness, and edema around the joint.
Treatment involves immediate surgical intervention to open the joint by free incision and counter-incision for adequate drainage. The limb must be carefully cleansed with ether and bichloride solution before surgery. Instruments used are simple: a scalpel, artery forceps, rubber drains, and an irrigator. The goal is ample drainage and subsequent antisepsis.
For knee arthrotomy under general anesthesia, two incisions are made—one external and one internal—to ensure thorough drainage. Drainage tubes are placed to prevent pus retention. Postoperative care includes twice-daily irrigation and dressing changes until the joint heals.

In cases of voluminous hemarthrosis or serous exudation, knee puncture may be performed with careful aseptic technique. The same principles apply for ankle, elbow, wrist, shoulder, and hip joint surgeries.

Key Takeaways
- Septic arthritis requires immediate surgical intervention.
- Proper antisepsis is crucial during joint surgeries to prevent further infection.
- Drainage and irrigation are essential steps in the treatment of septic arthritis.
Practical Tips
- Use sterile instruments and solutions for all procedures involving open joints.
- Ensure thorough drainage by making counter-incisions when necessary.
- Monitor patient temperature closely post-surgery to detect any signs of infection.
Warnings & Risks
- Improper surgical technique can lead to severe complications such as permanent joint damage or loss of function.
- Failure to maintain aseptic conditions during surgery increases the risk of further infection and sepsis.
Modern Application
While modern medicine has advanced significantly since 1915, the principles of emergency joint surgery for septic arthritis remain largely unchanged. The importance of proper antisepsis, thorough drainage, and immediate surgical intervention to prevent permanent damage or loss of function is still critical today.
