Management Guidelines for Infection After ACL Reconstruction: Expert Opinion Statement Based on the Modified Delphi Survey of Indian Arthroscopy Surgeons

AIM

Infection after anterior cruciate ligament (ACL) reconstruction, though rare, is a potentially devastating complication and the evidence-based recommendation on the various topics in its management is limited. The purpose of this study was to develop recommendations for the prevention and management of infections in ACL reconstruction surgery by performing a structured expert consensus survey using Delphi methodology.

MATERIALS AND METHODS

22 topics of relevance in the prevention and management of infection following ACL reconstruction were chosen from an extensive literature review. 30 panelists were requested to respond to a three-round survey, with feedback, to develop a consensus statement on the topics.

RESULTS

Consensus statements could be prepared in eleven out of twenty-two topics including: the graft is retained at the first arthroscopic debridement, the graft is removed when repeated debridement are needed, and revision ACL reconstruction is needed only if the patient develops instability. Concurrence could be obtained in the topics including: longer duration of antibiotics is needed in immunocompromised patients, soaking graft in antibiotic solution reduces infection risk, and knee swelling without warmth does not suggest infection.

CONCLUSIONS

A proper skin preparation, a longer course of antibiotics in immunocompromised patients, and soaking the graft in antibiotics reduces the risk of infection. In case of infection, a healthy-looking graft must be retained at the first debridement and if the graft must be removed, revision ACL reconstruction is advised only if the patient develops instability.

Tourniquet Use in Arthroscopic ACL Reconstruction: A Blinded Randomized Trial

INTRODUCTION

Despite knowing, that tourniquet induces ischemia and soft tissue damage surgeons still use it. The purpose of this study is to compare post operative pain and quadriceps function in patients undergoing arthroscopy assisted ACL reconstruction with tourniquet and without tourniquet.

METHODS

A blinded randomized prospective trial conducted at Orthopaedic department of a tertiary institute in India from Feb 2019 to June 2019. 45 patients undergoing Arthroscopic ACL reconstruction aged between 18 and 60 years were recruited in the study according to selection criteria. Patients were distributed in 2 groups randomly, namely, tourniquet and non-tourniquet. Preoperatively serum CPK measurement and thigh girth measurement was done. Following standard arthroscopic procedure VAS score monitoring for pain was done for 5 days. Serum CPK levels were performed on postoperative day 1. Thigh girth was measured on postoperative day 21.

RESULT

Pain was significantly high in patients in whom tourniquet was used. VAS scores were significantly high in tourniquet group. Tourniquet group patients required more amount of additional analgesics in postoperative period (p < 0.001). Serum CPK levels were comparable preoperatively while significantly high postoperatively in tourniquet group (p < 0.001). Difference in mean of thigh girth was significant between the groups (p < 0.001) and there is difficulty experienced by patients in performing straight leg raise test after tourniquet use (p = 0.002).

CONCLUSION

Tourniquet use is associated with increased pain, analgesic requirement, damage to muscles and compromises muscle function in early postoperative period. This can not only lead to increased patient discomfort but also difficult initial rehabilitation. Arthroscopic procedures can be uneventfully performed without the use of a tourniquet, and alternative methods should be looked upon and emphasized.

External fixation of intertrochanteric fractures of the femur

External fixation was used in the treatment of 154 intertrochanteric fractures of the femur over a period of eight years. Good fixation and early ambulation was achieved in all cases. Blood loss was slight. There were 12 deaths due to medical causes unrelated to the surgical procedure. Deep pin-track infection occurred in six cases and late displacement of the fracture fragments in nine. The average time for union was 16 weeks. The technique is simple, quick and inexpensive, and causes minimal surgical trauma. All these features are particularly relevant where resources are limited.

Shoulder rheumatoid arthritis associated with chondromatosis, treated by arthroscopy

We present a case of rheumatoid arthritis that affected the right shoulder and was associated with chondromatosis and multiple loose body formation. The arthritis was treated arthroscopically with satisfactory results after a follow-up period of 15 months. In our case, arthroscopic debridement and partial synovectomy not only relieved the pain but also improved the range of motion the night after surgery. The multiple loose bodies irritating the synovium and causing effusion, crepitus, and locking were also removed. One may need to change portals of the scope and suction cannula to remove loose bodies in different joint spaces. The subacromial space must be searched for loose bodies. Thorough cleaning, lavage, and synovectomy are important parts of this surgery. The continuous passive motion (CPM) machine in the immediate postoperative period was helpful.
