“…This mechanism seems to be one of the main factors, maybe even the leading factor, in the avoidance of THA dislocation [13, 35, 37–39]. This phenomenon has been described in detail by Prietzel et al [35, 38]. A shorter postoperative hospitalization period demonstrates that the application of the modified, less-invasive, capsule preserving R-THA technique is accompanied by further medical and economic benefits.…”

“…Some authors supported this theory by pointing out that the highest risk for dislocation occurs immediately after surgery before any pseudo-capsule has reformed in patients with previous capsular resection [38]. Beyond that, another study demonstrated that a repaired posterior capsule remained intact in 90% of patients at 3-months follow-up [19].…”

“…Preservation and repair of the capsule, supported by the use of larger prosthetic heads if possible, helps to re-establish more of the pre-existing protection against dislocation, which is physiologically provided by the permanent hip stabilising effect of atmospheric pressure [38]. This mechanism seems to be one of the main factors, maybe even the leading factor, in the avoidance of THA dislocation [13, 35, 37–39].…”

BackgroundDislocation following total hip arthroplasty has to date not been resolved satisfactorily. Previous work has shown that using a less-invasive adaption of Bauer’s lateral transgluteal approach with capsular repair significantly reduces dislocation rates in primary total hip arthroplasty. The aim of this retrospective cohort study was to assess whether this approach also helps to reduce the dislocation rate in revision total hip arthroplasty.MethodsWe analyzed revision total hip arthroplasty cases performed between 10/2005 and 12/2013 in our department, classifying capsular repair cases as study group and capsular resection cases as control group. The WOMAC score, the dislocations and the revisions were observed.ResultsA total of 259 cases were included, 100 in the study group and 159 in the control group. In the 12-month follow-up, dislocation rates were significantly lower in the study group (3%, n = 3) compared to the control group (21.4%, n = 34; p = 0.001). Overall follow-up periods were 49 and 79 months, revision frequencies were 10 and 29%, pain improvements were 5.5 compared to 4.4 and the WOMAC global scores averaged 2.0 ± 2.1 and 2.9 ± 2.6 for the study group and the control group, respectively.ConclusionThe modified, less-invasive, lateral transgluteal approach with capsular repair was accompanied by an 86% reduction in dislocation rates when compared to the conventional technique with capsular resection via the anterolateral Watson-Jones-approach. Capsular repair is possible in about 60% of the revision total hip arthroplasty cases, may be considered as beneficial to avoid dislocation and can therefore be recommended.

“…Gegen die ROM als Hauptursache der geringeren Luxationsneigung spricht deren asymptotische Zunahme mit dem Kopfdurchmesser, die einen erheblichen Zuwachs im Bereich geringer Kopfdurchmesser zeigt, während die ROM-Zunahme bei größer werdenden Köpfen gegen null geht [46]. Dieses Verhalten steht im Widerspruch zur geringen Abnahme der Luxationsrate von 32mm-Köpfen im Vergleich zu 28-mm-Köpfen [13] und zur massiven Abnahme bei Einsatz von 36-mm-Köpfen in Relation zu 28mm-Köpfen [6,7].…”

In total hip arthroplasty (THA), femoral head diameter has not been regarded as a key parameter which should be restored when reconstructing joint biomechanics and geometry. Apart from the controversial discussion on the advantages and disadvantages of using larger diameter heads, their higher cost is another important reason that they have only been used to a limited extent. The goal of this study was to analyse the price structure of prosthetic heads in comparison to other components used in THA. A large group of patients with hip endoprostheses were evaluated with respect to the implanted socket diameter and thus the theoretically attainable head diameter. The relative prices of various THA components (cups, inserts, stems and ball heads) distributed by two leading German manufacturers were determined and analysed. Special attention was paid to different sizes and varieties in a series of components. A large patient population treated with THA was evaluated with respect to the implanted cup diameter and therefore the theoretically attainable head diameter. The pricing analysis of the THA components of two manufacturers showed identical prices for cups, inserts and stems in a series. In contrast to this, the prices for prosthetic heads with a diameter of 36-44 mm were 11-50 % higher than for 28 mm heads. Identical prices for larger heads were the exception. The distribution of the head diameter in 2719 THA cases showed significant differences between the actually implanted and the theoretically attainable heads. There are proven advantages in using larger diameter ball heads in THA and the remaining problems can be solved. It is therefore desirable to correct the current pricing practice of charging higher prices for larger components. Instead, identical prices should be charged for all head diameters in a series, as is currently established practice for all other THA components. Thus when reconstructing biomechanics and joint geometry in THA, it should be possible to recover not only leg length, femoral offset and antetorsion of the femoral neck, but also to approximately restore the diameter of the femoral head and thereby optimise the functional outcome.

“…Emerging research investigates the biomechanical role and properties of the capsule [19][20][21][22][23]. This indicates that the contribution of the capsule to the mechanics of the joint may be more extensive than passive stabilization alone, particularly as no significant difference has been noted between the biomechanical properties of the capsular ligaments [22].…”

Innervation of the hip joint capsular complex: A systematic review of histological and immunohistochemical studies and their clinical implications for contemporary treatment strategies in total hip arthroplasty

The hip joint capsule contributes to the stability of the hip joint and lower extremity, yet this structure is incised and often removed during total hip arthroplasty (THA). Increasing incidence of osteoarthritis is accompanied by a dramatic rise in THAs over the last few decades. Consequently, to improve this treatment, THA with capsular repair has evolved. This partial restoration of physiological hip stability has resulted in a substantial reduction in post-operative dislocation rates compared to conventional THA without capsular repair. A further reason for the success of this procedure is thought to be the preservation of the innervation of the capsule. A systematic review of studies investigating the innervation of the hip joint capsular complex and pseudocapsule with histological techniques was performed, as this is not well established. The literature was sought from databases Amed, Embase and Medline via OVID, PubMed, ScienceDirect, Scopus and Web of Science; excluding articles without a histological component and those involving animals. A total of 21 articles on the topic were identified. The literature indicates two primary outcomes and potential clinical implications of
