Hip and groin injuries are common in athletes
who take part in high level sports. Adductor muscle tendon injuries represent
a small but important number of these injuries. Avulsion of the
tendons attached to the symphysis pubis has previously been described:
these can be managed both operatively and non-operatively. We describe
an uncommon variant of this injury, namely complete avulsion of
the adductor sleeve complex: this includes adductor longus, pectineus
and rectus abdominis. We go on to describe a surgical technique
which promotes a full return to the pre-injury level of sporting
activity. Over a period of ten years, 15 high-level athletes with an MRI-confirmed
acute adductor complex avulsion injury (six to 34 days old) underwent
surgical repair. The operative procedure consisted of anatomical
re-attachment of the avulsed tissues in each case and mesh reinforcement
of the posterior inguinal wall in seven patients. All underwent a
standardised rehabilitation programme, which was then individualised
to be sport-specific. One patient developed a superficial wound infection, which was
successfully treated with antibiotics. Of the 15 patients, four
complained of transient local numbness which resolved in all cases.
All patients (including seven elite athletes) returned to their
previous level of participation in sport. Cite this article:
The aims of the study were to report for a cohort aged younger than 40 years: 1) indications for HRA; 2) patient-reported outcomes in terms of the modified Harris Hip Score (HHS); 3) dislocation rate; and 4) revision rate. This retrospective analysis identified 267 hips from 224 patients who underwent an hip resurfacing arthroplasty (HRA) from a single fellowship-trained surgeon using the direct lateral approach between 2007 and 2019. Inclusion criteria was minimum two-year follow-up, and age younger than 40 years. Patients were followed using a prospectively maintained institutional database.Aims
Methods
Although the Fitmore Hip Stem has been on the market for almost 15 years, it is still not well documented in randomized controlled trials. This study compares the Fitmore stem with the CementLeSs (CLS) in several different clinical and radiological aspects. The hypothesis is that there will be no difference in outcome between stems. In total, 44 patients with bilateral hip osteoarthritis were recruited from the outpatient clinic at a single tertiary orthopaedic centre. The patients were operated with bilateral one-stage total hip arthroplasty. The most painful hip was randomized to either Fitmore or CLS femoral component; the second hip was operated with the femoral component not used on the first side. Patients were evaluated at three and six months and at one, two, and five years postoperatively with patient-reported outcome measures, radiostereometric analysis, dual-energy X-ray absorptiometry, and conventional radiography. A total of 39 patients attended the follow-up visit at two years (primary outcome) and 35 patients at five years. The primary outcome was which hip the patient considered to have the best function at two years.Aims

Hip resurfacing arthroplasty (HRA) is typically indicated for young and active patients. Due to the longevity of arthroplasty, these patients are likely to undergo revision surgery during their lifetime. There is a paucity of information on the long-term outcome of revision surgeries performed after failed HRA. The aim of our study was to provide survivorship data as well as clinical scores after HRA revisions. A total of 42 patients (43 hips) were revised after HRA at our centre to a variety of devices, including four HRA and 39 total hip arthroplasties (THAs). In addition to perioperative complications, University of California, Los Angeles (UCLA) hip scores and 12-Item Short-Form Health Survey questionnaire (SF-12) quality of life scores were collected at follow-up visits after the primary HRA and after revision surgery.Aims
Methods
This paper aims to review the evidence for patient-related factors associated with less favourable outcomes following hip arthroscopy. Literature reporting on preoperative patient-related risk factors and outcomes following hip arthroscopy were systematically identified from a computer-assisted literature search of Pubmed (Medline), Embase, and Cochrane Library using Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and a scoping review.Aims
Methods
Surface replacement arthroplasty (SRA), compared with traditional total hip arthroplasty (THA), is more expensive and carries unique concern related to metal ions production and hypersensitivity. Additionally, SRA is a more demanding procedure with a decreased margin for error compared with THA. To justify its use, SRA must demonstrate comparable component survival and some clinical advantages. We therefore performed a systematic literature review to investigate the differences in complication rates, patient-reported outcomes, stress shielding, and hip biomechanics between SRA and THA. A systematic review of the literature was completed using MEDLINE and EMBASE search engines. Inclusion criteria were level I to level III articles that reported clinical outcomes following primary SRA compared with THA. An initial search yielded 2503 potential articles for inclusion. Exclusion criteria included review articles, level IV or level V evidence, less than one year’s follow-up, and previously reported data. In total, 27 articles with 4182 patients were available to analyze.Aims
Materials and Methods
This study presents the long-term survivorship, risk factors for prosthesis survival, and an assessment of the long-term effects of changes in surgical technique in a large series of patients treated by metal-on-metal (MoM) hip resurfacing arthroplasty (HRA). Between November 1996 and January 2012, 1074 patients (1321 hips) underwent HRA using the Conserve Plus Hip Resurfacing System. There were 787 men (73%) and 287 women (27%) with a mean age of 51 years (14 to 83). The underlying pathology was osteoarthritis (OA) in 1003 (75.9%), developmental dysplasia of the hip (DDH) in 136 (10.3%), avascular necrosis in 98 (7.4%), and other conditions, including inflammatory arthritis, in 84 (6.4%).Aims
Patients and Methods
The repair of chondral lesions associated with
femoroacetabular impingement requires specific treatment in addition
to that of the impingement. In this single-centre retrospective
analysis of a consecutive series of patients we compared treatment
with microfracture (MFx) with a technique of enhanced microfracture
autologous matrix-induced chondrogenesis (AMIC). Acetabular grade III and IV chondral lesions measuring between
2 cm2 and 8 cm2 in 147 patients were treated
by MFx in 77 and AMIC in 70. The outcome was assessed using the
modified Harris hip score at six months and one, two, three, four
and five years post-operatively. The outcome in both groups was
significantly improved at six months and one year post-operatively.
During the subsequent four years the outcome in the MFx group slowly deteriorated,
whereas that in the AMIC group remained stable. Six patients in
the MFx group subsequently required total hip arthroplasty, compared
with none in the AMIC group We conclude that the short-term clinical outcome improves in
patients with acetabular chondral damage following both MFx and
AMIC. However, the AMIC group had better and more durable improvement,
particularly in patients with large (≥ 4 cm2) lesions. Cite this article:
There is little in the literature on the level
of participation in sports which patients undertake after total
hip replacement (THR). Our aims in this study were to determine
first, the level of sporting activity, second, the predictive factors
for returning to sporting activity, and third, the correlation between
participation in sports and satisfaction after THR. We retrospectively
identified 815 patients who had undergone THR between 1995 and 2005. All
were asked to complete a self-administered questionnaire regarding
their sporting activity. A total of 571 patients (71%) met the inclusion
criteria and completed the evaluation. At a mean follow-up of 9.8
years ( In conclusion, we found that most patients participate in sporting
activity after THR, regardless of the advice of their surgeon, and
that there is a correlation between the level of participation and
pre-operative function, motivation, duration of symptoms and post-operative
satisfaction. Cite this article:
Femoroacetabular impingement (FAI) causes pain
and chondrolabral damage via mechanical overload during movement
of the hip. It is caused by many different types of pathoanatomy,
including the cam ‘bump’, decreased head–neck offset, acetabular
retroversion, global acetabular overcoverage, prominent anterior–inferior
iliac spine, slipped capital femoral epiphysis, and the sequelae
of childhood Perthes’ disease. Both evolutionary and developmental factors may cause FAI. Prevalence
studies show that anatomic variations that cause FAI are common
in the asymptomatic population. Young athletes may be predisposed
to FAI because of the stress on the physis during development. Other
factors, including the soft tissues, may also influence symptoms and
chondrolabral damage. FAI and the resultant chondrolabral pathology are often treated
arthroscopically. Although the results are favourable, morphologies
can be complex, patient expectations are high and the surgery is
challenging. The long-term outcomes of hip arthroscopy are still
forthcoming and it is unknown if treatment of FAI will prevent arthrosis.
The direct anterior approach in total hip replacement anatomically offers the chance to minimise soft-tissue trauma because an intermuscular and internervous plane is explored. This motivated us to abandon our previously used transgluteal approach and to adopt the direct anterior approach for total hip replacement. Using MRI, we performed a retrospective comparative study of the direct anterior approach with the transgluteal approach. There were 25 patients in each group. At one year post-operatively all the patients underwent MRI of their replaced hips. A radiologist graded the changes in the soft-tissue signals in the abductor muscles. The groups were similar in terms of age, gender, body mass index, complexity of the reconstruction and absence of symptoms. Detachment of the abductor insertion, partial tears and tendonitis of gluteus medius and minimus, the presence of peri-trochanteric bursal fluid and fatty atrophy of gluteus medius and minimus were significantly less pronounced and less frequent when the direct anterior approach was used. There was no significant difference in the findings regarding tensor fascia lata between the two approaches. We conclude that use of the direct anterior approach results in a better soft-tissue response as assessed by MRI after total hip replacement. However, the impact on outcome needs to be evaluated further.
