Seromas are collections of serous fluid that can develop following surgical procedures and may persist as fibrous-lined pseudocysts if not adequately treated. In orthopedic surgery, particularly after arthroplasty, seromas can impair wound healing, increase pain, and limit postoperative rehabilitation, potentially compromising patient recovery. Current treatment strategies including compression, percutaneous aspiration, and repeat surgical intervention have variable success, and aspiration carries the risk of introducing bacteria into an otherwise sterile fluid collection. Sclerotherapy has been proposed as an alternative strategy to induce fibrosis within the cavity and eliminate the potential space. Doxycycline, a tetracycline antibiotic commonly used for pleurodesis, has demonstrated sclerosing properties through mechanisms including mesothelial cell destruction, inhibition of fibrinolysis, and stimulation of fibroblast activity. While doxycycline sclerotherapy has shown success in treating conditions such as Morel-Lavallée lesions and has been described in isolated orthopedic case reports, its role in managing postoperative seromas after arthroplasty remains poorly studied. Further investigation is needed to determine whether doxycycline injection may serve as a safe and effective treatment to reduce persistent seromas and the need for additional interventions in orthopedic patients.

| Hip Disability and Osteoarthritis Outcome Score Junior (HOOS JR ) | Patient-reported questionnaire administered during routine postoperative clinic visits using the Hip Disability and Osteoarthritis Outcome Score Junior (HOOS JR) questionnaire, which evaluates joint-specific pain, stiffness, and functional ability following orthopedic surgery. Score range is from 0 to 100, with higher scores indicating better hip health and function. | 6 months postoperatively |
| Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health-10 | The PROMIS Global Health-10 is a validated patient-reported outcome questionnaire assessing overall physical, mental, and social health. It includes items that generate two standardized summary scores: Global Physical Health (GPH) and Global Mental Health (GMH). Raw scores are converted to T-scores, each scaled with a mean of 50 and a standard deviation of 10, where higher scores indicate better overall health status. | 6 months postoperatively |
| UCLA Activity Score | The University of California, Los Angeles (UCLA) Activity Score is a validated patient-reported measure assessing physical activity level and functional mobility. Scores range from 1 to 10, where higher scores indicate higher activity levels (1 = completely inactive, dependent; 10 = regular participation in impact sports). The score reflects the patient's usual activity level during daily life and recreational activities. | 6 months postoperatively |
| EQ-5D Health-Related Quality of Life Score | Patient-reported questionnaire administered during routine postoperative clinic visits. Participants will complete the standard EQ-5D instrument, and responses will be converted to numerical index scores according to scoring guidelines. Scores range from values below 0 (indicating health states worse than death) to 1.0 (indicating full health), with higher scores reflecting better health-related quality of life. | 6 months postoperatively |
