ABSTRACT
PURPOSE: Recent studies have shown that the incidence of glove lesions during arthroscopy is much lower than that during primary and revision arthroplasty. However, the rate of glove damage after knot tying has not yet been systematically recorded. Therefore, the aim of the study was to determine the impact of surgical knot tying on glove integrity. It was hypothesized that knot tying increases the rate of glove damage, especially in arthroscopic surgery, which could be of special relevance in the treatment of rotator cuff tears. METHODS: Gloves that were changed immediately before suturing and only worn during knot tying were investigated for their integrity by means of water tightening test according to EN455. A total of 234 gloves from 40 total hip arthroplasties (THAs), 42 total knee arthroplasties (TKAs) and 36 rotator cuff repairs (RCRs) were collected. A bacterial pass-through test (BPTT) on glove lesions was performed under simulated sterile surgical conditions for 3 surgeons after a wear duration of 45 min. RESULTS: Glove damage by knot tying occurred in 25% of THA, 36.6% of TKA and 25% of RCR surgeries. In THA, the pulling hand (PH) was affected in 46.2%, and the main area of damage (15.4%) was detected on the tip of the middle finger; in TKAs the PH was damaged in 75%, and in RCRs the PH was affected in 66.7%, with most of the lesions (20% each) occurring on the tip of the index finger and the ring finger. The BPTT showed Staphylococcus hominis and Bacillus cereus. CONCLUSION: Intraoperative knot tying causes damage to gloves, which is of special relevance for arthroscopic surgery. Whereas knot tying is only partly responsible for glove damage in arthroplasty, the general rate of glove damage in arthroscopic surgery is low without knot tying. The surgical knot tying process must be understood as a possible damaging impact on the glove. Therefore, single gloving is not recommended, which is especially important in arthroscopic surgery, where double gloving is not yet standard. LEVEL OF EVIDENCE: IV.

CASE: A 54-year-old patient presented with low-velocity hyperflexion knee trauma while falling at a ski lift with anterior cruciate ligament (ACL) rupture and avulsion fractures of both posterior meniscal attachments. Meniscal avulsions were treated arthroscopically using transtibial sutures; a partial medial collateral ligament tear was treated conservatively. Six weeks later, reconstruction of the ACL was performed, and both meniscal attachments were stable. CONCLUSION: Hyperflexion of the knee puts direct shear and compressive force on the posterior tibia. This can result in ligament injuries combined with avulsion fractures of both posterior meniscal attachments. Arthroscopic treatment is a practicable technique for this type of injury.
