Concealed cosmetic closure in total knee replacement surgery - A prospective audit assessing appearance and patient satisfaction.

Objective: With the trend towards accelerated rehabilitation, the method of skin closure has become increasingly important in orthopedic surgery. It is imperative to evaluate a technique that provides superior clinical and cosmetic results specifically for TKA, due to relatively thin skin anterior to the knee making poor wound healing an issue of concern. We conducted a prospective, single-arm audit evaluating the patient assessments of incision cosmesis for a novel technique in TKA wound closure called Concealed Cosmetic Closure (CCC).

Methods: 570 knees were included in the study whose wound was closed with concealed cosmetic subcuticular interrupted sutures (CCCIS) between January 2014 and May 2016. A validated, ordinal questionnaire, Stony Brooks Scar Evaluation Scale (SBSES) designed to elicit a score evaluating scar satisfaction was interviewed by the investigators to patients 6 months to 3 years postoperatively.

Results: CCC is a simple and relatively rapid single-operator technique that takes about 7-10 min to close 11-17 cm knee incision. In our study, the mean score for Stony Brook Scar Evaluation Scale (SBSES) was 4.4 (SD of 0.73) (range 3-5). The scar was rated highly in terms of cosmesis, patient satisfaction and appearance of the wound.

Conclusion: CCC is an effective modality for skin closure in total knee arthroplasty providing superior cosmetic healing with minimal complications leading to improved long term patient satisfaction.
