Objective: According to current recommendations, large cartilage defects of the hip over 2 cm2 are suggested to undergo autologous chondrocyte transplantation (ACT), while small defects should be treated with microfracture. We investigated if patients with small chondral defects of the hip joint (≤100 mm2) actually benefit from microfracture. Design: In this retrospective multicenter cohort study 40 patients with focal acetabular cartilage defects smaller than 100 mm2 and of ICRS grade ≥2 caused by femoroacetabular impingement were included. Twenty-six unrandomized patients underwent microfracture besides treatment of the underlying pathology; in 14 patients cartilage lesions were left untreated during arthroscopy. Over a mean follow-up of 28.8 months patient-reported outcome was determined using the iHOT33 (international hip outcome tool) and the VAS (visual analog scale) for pain. Results: The untreated group showed a statistically significant improvement of the iHOT33 after 12 (p = 0.005), 24 (p = 0.019), and 36 months (p = 0.002) compared to the preoperative score, whereas iHOT33 in the microfracture group did not reveal statistically significant changes over time. There was no significant difference between both groups on any time point. Regarding pain both groups did not show a significant improvement over time in the VAS. Conclusion: The subjective outcome of patients with small cartilage defects of the hip (≤100 mm2) improves 12 months after arthroscopic FAIS surgery without any cartilage treatment. However, no improvement could be seen after microfracture. Therefore, a reserved surgical treatment for small cartilage defects of the hip under preservation of the subchondral bone is recommended especially if a simultaneous impingement correction is performed.

Studienziel: Bei Frühmobilisation unter Vollbelastung sollte die Primärstabilität von zwei verschiedenen zementfreien Titan-Hüftprothesenschäften mittels Röntgen-Stereometrie-Analyse (RSA) untersucht werden. Methode: 26 Patienten (∅ 60,8 ± 7,5 J., 16 m, 10 w, BMI 27,7 ± 3,9 kg/m2) wurden mit dem anatomisch geformten Image-Schaft (IS) (Image, Fa. Smith & Nephew, Schenefeld, Deutschland) und 20 Patienten (∅ 60,0 ± 10,9 J., 12 m, 8 w, BMI 27,5 ± 3,7 kg/m2) mit dem Bicontact-Geradschaft (BS) (Bicontact, Fa Aesculap, Tuttlingen, Deutschland) versorgt. RSA-Röntgenuntersuchungen erfolgten vor Mobilisation, 3 und 6 Wochen, 3, 6, 12 und 24 Monate postoperativ. Zusätzlich wurde der Harris-Hip-Score (HHS), der Western Ontario And McMasters Universities Osteoarthritis Index (WOMAC) sowie die Schmerzintensität mittels visueller Analogskala (VAS) erhoben. Ergebnisse: Innerhalb der ersten 3 Monate fand sich in den beiden Gruppen die stärkste Migration (Einsinken) (IS 0,647 mm, BS 0,54 mm). Ab dem 6. Monat post-OP zeigten sich nur noch Migrationen im Bereich der RSA-Messgenauigkeit. Nach 2 Jahren betrug die Migration 1,07 mm ± 0,07 mm (IS), bzw. 0,97 mm ± 0,18 mm (BS). Es konnten zu keinem Untersuchungszeitraum signifikante Unterschiede festgestellt werden. Die klinische Untersuchung zeigte eine deutliche Verbesserung des HHS, des WOMAC-Index und der VAS im Verlauf von 2 Jahren. Schlussfolgerung: Beide Prothesenschäfte zeigten eine gute Primärstabilität und eine gute Folgestabilität im untersuchten Zeitraum bei sehr guten klinischen Ergebnissen. Die Migrationswerte der beiden Schäfte lagen im Bereich publizierter RSA-Daten für zementverankerte Implantate. Aim: Under early mobilisation and full weightbearing the primary stability of two different cementless hip stems should be examined by using Roentgen Stereometric Analysis (RSA). Method: 26 patients (∅ 60.8 ± 7.5 J., 16 m, 10 w, BMI 27.7 ± 3.9 kg/m2) received a total hip arthroplasty with an anatomical designed image-stem (IS) (Smith & Nephew, Schenefeld, Germany), 20 patients (∅ 60.0 ± 10.9 J., 12 m, 8 w, BMI 27.5 ± 3.7 kg/m2) the Bicontact-stem (BS) (Aesculap, Tuttllingen, Germany). RSA measurements were done before mobilizing, 3 and 6 weeks, 3, 6, 12 and 24 months postoperatively. Furthermore the patients had to estimate their pain on a visually scale (VAS). We registrated the Harris-Hip-Score (HHS) and the Western Ontario and McMasters Universities Osteoarthritis Index (WOMAC). Results: Both stems showed the maximum of subsidence in the first 3 months (IS 0.647 mm, BS 0.54 mm). 6 months postoperative the measured migrations were in the range of the accuracy. After 2 years the subsidence was 1.07 mm ± 0.07 mm for the IS-group, 0.97 mm ± 0.18 mm for the BS-group. There were no significant differences in the examined parameters between the both groups. An excellent prostheses function and high activity grade with a high WOMAC score, a high HHS and a low VAS was founded for both groups. Conclusion: Both cementless implanted titanium hip stems showed a sufficient primary and midterm stability with excellent clinical results. The measured migrations do not differ from those given in literature for cemented stems.

Die Ätiologie der Labrumläsionen des Hüftgelenks ist vielgestaltig. Eine alleinige Labrumerkrankung ohne zugrunde liegende Pathologie ist sehr unwahrscheinlich. Labrumläsionen des Hüftgelenks treten häufig auf, und bei frustraner konservativer Therapie kommen operativ offene und arthroskopische Verfahren zum Einsatz. Die Ergebnisse nach operativer Therapie sind abhängig vom Vorhandensein einer Begleitpathologie des Hüftgelenkes.
