Midterm-clinical Outcomes after Hip Arthroscopy in Middle-aged Patients with Early Osteoarthritis / 대한고관절학회지

PURPOSE: Although the number of hip arthroscopies is rapidly increasing in non-elderly patients, outcomes of this procedure in middle-aged patients are not well documented or clearly understood. The purpose of this study was to evaluate the clinical and radiological outcomes after hip arthroscopy in middle-aged patients with early osteoarthritis.MATERIALS AND METHODS: This retrospective study analyzed 189 patients with early osteoarthritis of various diagnoses aged 40 years or older who underwent hip arthroscopy between January 2010 and December 2015. Clinical (e.g., modified Harris hip score [mHHS], hip outcome score-activities of daily living [HOS-ADL], visual analogue scale [VAS] for pain, range of motion) and radiological (change of Tönnis grade) outcomes were assessed at a minimum of 3-year follow-up.RESULTS: The mean preoperative and final mHHS and HOS-ADL improved from 61.2 and 60.6 to 79.5 and 81.8, respectively, while the VAS pain score decreased from 6.3 to 3.2 (P<0.001). Although the mean range of internal rotation and flexion increased from 14.2 and 100.7° preoperatively to 30.4 and 110.6° at 1-year postoperatively, they decreased slightly to 27.4 and 105.4° at the final follow-up, respectively. Eight cases (4.2%) underwent revision arthroscopic surgery and three cases (1.6%) were converted to total hip arthroplasty.CONCLUSION: Patients with early-stage osteoarthritis of various diagnoses achieved improved clinical outcomes. Therefore, using hip arthroscopy in middle-aged patients with early osteoarthritis, it is possible to achieve good surgical options.

Tratamiento artroscópico del pellizcamiento femoroacetabular combinado: técnica quirúrgica / Arthroscopic treatment of combined femoroacetabular impingement: surgical technique

The hip can be a source of pain and physical impairment. Femoroacetabular impingement is one of many diagnoses. Femoroacetabular impingement has been associated to labral tears and early osteoarthritis. Treatment for this pathology may include surgery. The procedure will vary depending on the kind of impingement and concomitant lesions. The different surgical procedures have been described by non-arthroscopic approaches. As in other joints, the arthroscopic approach implies certain advantages, making it an attractive choice considering its lower frequency of complications. One of the limitations of arthroscopic procedures isthe technical difficulty it implies. Our group has performed 43 hip arthroscopic procedures for the treatment of femoroacetabular impingement with the technique described in this paper. Good to excellent results have been obtained in 91percent of the cases (39/43), in a short term follow up. In spite of the technical difficulties and complications proper of the procedure, the arthroscopic approach presents itself as a good alternative for the treatment of femoroacetabular impingement, allowing us to perform.

La articulación de la cadera puede ser origen de dolor y limitación funcional. Entre otros diagnósticos se encuentra el pellizcamiento femoroacetabular. El diagnóstico de pellizcamiento de cadera se ha visto asociado a rotura del labrum y artrosis precoz. El tratamiento de esta patología puede incluir cirugía. El procedimiento a realizar depende del tipo de pellizcamiento y lesiones asociadas. Los distintos procedimientos quirúrgicos han sido reportados por vía abierta. Al igual que en otras articulaciones, la vía artroscópica presenta ventajas relativas haciéndola una opción atractiva por su menor índice de complicaciones. Una de las limitantes de la artroscopía es la dificultad técnica que ésta plantea. Nuestro grupo ha realizado 43 artroscopías de cadera para el tratamiento del pellizcamiento femoroacetabular con la técnica aquí descrita. Se han obtenido buenos a excelentes resultados en 91por ciento de los casos (39/43), en un seguimiento a corto plazo. A pesar de las dificultades técnicas y complicaciones inherentes al procedimiento, la vía artroscópica se presenta como una buena alternativa de tratamiento de los pellizcamientos femoroacetabulares pudiendo hacerse desinserción del labrum, acetabuloplastia, re-inserción y bumpectomía.
