The aim of our study was to determine whether specific mechanoreceptors would regenerate in the pseudocapsule that had formed in place of the native capsule after primary total hip replacement (THR).We studied 20 full-thickness samples of pseudocapsule tissue from patients undergoing revision THR surgery. All patients had had a partial capsulectomy during primary THR. The specimens were stained with haematoxylin and eosin and immunohistochemical dyes using a monoclonal antibody against S-100 protein.No mechanoreceptors were detected in the pseudocapsule of any of the specimens.Our study concludes that if a partial capsulectomy is performed during primary THR, the replaced pseudocapsule will not have any active neurophysiological role in the hip. In this context, we recommend the preservation of hip joint capsule and an anatomical repair at the time of primary THR. Preservation of neurophysiologically viable tissue has been shown to reduce dislocation and may lead to better functional recovery.
我們研究的目的是確定在初次全髖關節置換術(THR)後,假關節囊內是否有再生的特定機械感受器。我們研究20個進行了初次THR手術的患者之完整厚度的假關節囊組織樣本。所有患者在初次THR中都 進行了部分關節囊切除術,假關節囊組織樣本以蘇木精、曙紅和S-100蛋白單克隆抗體的免疫組織化學染料染色。在所有假關節囊組織樣本中,沒有發現機械感受器。我們的研究報告結論是進行了初次THR手術後,置換的假關節囊並沒有在髖關節內進行有效的神經電, 生理作用。在這種情況下,我們建議在初次THR手術中保留原髖關節囊並進行解剖學修復。保存原組織的有效神經電生理作用,證明可以減少術後髖關節脫位,從而可能有更好的功能恢復。
