The purpose of this study was to evaluate the mid-term outcomes of autologous matrix-induced chondrogenesis (AMIC) for the treatment of larger cartilage lesions and deformity correction in hips suffering from symptomatic femoroacetabular impingement (FAI). This single-centre study focused on a cohort of 24 patients with cam- or pincer-type FAI, full-thickness femoral or acetabular chondral lesions, or osteochondral lesions ≥ 2 cm2, who underwent surgical hip dislocation for FAI correction in combination with AMIC between March 2009 and February 2016. Baseline data were retrospectively obtained from patient files. Mid-term outcomes were prospectively collected at a follow-up in 2020: cartilage repair tissue quality was evaluated by MRI using the Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score. Patient-reported outcome measures (PROMs) included the Oxford Hip Score (OHS) and Core Outcome Measure Index (COMI). Clinical examination included range of motion, impingement tests, and pain.Aims
Methods
We aimed to determine hip-related quality of life and clinical findings following treatment for neonatal hip instability (NHI) compared with age- and sex-matched controls. We hypothesized that NHI would predispose to hip discomfort in long-term follow-up. We invited those born between 1995 and 2001 who were treated for NHI at our hospital to participate in this population-based study. We included those that had Von Rosen-like splinting treatment started before one month of age. A total of 96 patients treated for NHI (75.6 %) were enrolled. A further 94 age- and sex-matched controls were also recruited. The Copenhagen Hip and Groin Outcome Score (HAGOS) questionnaire was completed separately for both hips, and a physical examination was performed.Aims
Methods
Periacetabular osteotomy is an effective way of treating symptomatic
hip dysplasia. We describe a new minimally invasive technique using
a modification of the Smith-Peterson approach. We performed a prospective, longitudinal cohort study to assess
for any compromise in acetabular correction when using this approach,
and to see if the procedure would have a higher complication rate
than that quoted in the literature for other approaches. We also
assessed for any improvement in functional outcome. From 168 consecutive patients (189 hips) who underwent acetabular
correction between March 2010 and March 2013 we excluded those who
had undergone previous pelvic surgery for DDH and those being treated
for acetabular retroversion. The remaining 151 patients (15 men,
136 women) (166 hips) had a mean age of 32 years (15 to 56) and the
mean duration of follow-up was 2.8 years (1.2 to 4.5). In all 90%
of cases were Tönnis grade 0 or 1. Functional outcomes were assessed
using the Non Arthritic Hip Score (NAHS), University of California,
Los Angeles (UCLA) and Tegner activity scores.Aims
Patients and Methods
This study aimed to evaluate the relationship between hip shape and mid-term function in Perthes’ disease. It also explored whether the modified three-group Stulberg classification can offer similar prognostic information to the five-group system. A total of 136 individuals aged 12 years or older who had Perthes’ disease in childhood completed the Patient-Reported Outcomes Measurement Information System (PROMIS) Mobility score (function), Nonarthritic Hip Score (NAHS) (function), EuroQol five-dimension five-level questionnaire (EQ-5D-5L) score (quality of life), and the numeric rating scale for pain (NRS). The Stulberg class of the participants’ hip radiographs were evaluated by three fellowship-trained paediatric orthopaedic surgeons. Hip shape and Stulberg class were compared to PROM scores.Aims
Methods
The mucopolysaccharidoses (MPS) are a group of
inherited lysosomal storage disorders with clinical manifestations relevant
to the orthopaedic surgeon. Our aim was to review the recent advances
in their management and the implications for surgical practice. The current literature about MPSs is summarised, emphasising
orthopaedic complications and their management. Recent advances in the diagnosis and management of MPSs include
the recognition of slowly progressive, late presenting subtypes,
developments in life-prolonging systemic treatment and potentially
new indications for surgical treatment. The outcomes of surgery
in these patients are not yet validated and some procedures have
a high rate of complications which differ from those in patients
who do not have a MPS. The diagnosis of a MPS should be considered in adolescents or
young adults with a previously unrecognised dysplasia of the hip.
Surgeons treating patients with a MPS should report their experience
and studies should include the assessment of function and quality
of life to guide treatment. Cite this article:
Slipped capital femoral epiphysis (SCFE) may
lead to symptomatic femoroacetabular impingement (FAI). We report our
experience of arthroscopic treatment, including osteochondroplasty,
for the sequelae of SCFE. Data were prospectively collected on patients undergoing arthroscopy
of the hip for the sequelae of SCFE between March 2007 and February
2013, including demographic data, radiological assessment of the
deformity and other factors that may influence outcome, such as
the presence of established avascular necrosis. Patients completed
the modified Harris hip score (mHHS) and the non-arthritic hip score
(NAHS) before and after surgery. In total, 18 patients with a mean age of 19 years (13 to 42),
were included in the study. All patients presented with pain in
the hip and mechanical symptoms, and had evidence of FAI (cam or
mixed impingement) on plain radiographs. The patients underwent arthroscopic osteoplasty of the femoral
neck. The mean follow-up was 29 months (23 to 56). The mean mHHS and NAHS scores improved from 56.2 (27.5 to 100.1)
and 52.1 (12.5 to 97.5) pre-operatively to 75.1 (33.8 to 96.8, p
= 0.01) and 73.6 (18.8 to 100, p = 0.02) at final follow-up, respectively.
Linear regression analysis demonstrated a significant association
between poorer outcome scores and increased time to surgery following SCFE
(p <
0.05 for all parameters except baseline MHHS). Symptomatic FAI following (SCFE) may be addressed using arthroscopic
techniques, and should be treated promptly to minimise progressive
functional impairment and chondrolabral degeneration. Take home message: Arthroscopy of the hip can be used to treat
femoroacetabular impingement successfully following SCFE. However,
this should be performed promptly after presentation in order to
prevent irreversible progression and poorer clinical outcomes. Cite this article:
We report patient-reported outcomes and complications
associated with contemporary periacetabular osteotomy (PAO) surgery
in treating symptomatic acetabular dysplasia and compare these outcomes
with total hip arthroplasty (THA) in patients with similar demographic
details. Two consecutive cohorts included patients between aged
18 to 40 years who had undergone either PAO (100 hips; 24 male,
76 female) or THA (55 hips; 18 male, 37 female). At a mean follow-up
of 5.9 years (2 to 13), there was significant improvement in the
modified Harris hip pain (p <
0.001, PAO and p <
0.001, THA),
function (p <
0.001, PAO and p = 0.001, THA), and total scores
(p <
0.001, PAO and p <
0.001, THA) within each cohort. There
were no significant differences in the clinical outcome scores between
the groups. Complication rates were low and similar in each cohort
(p = 0.68). Similar to THA, contemporary PAO surgery is a clinically
effective procedure that improves function and activity levels,
provides pain relief and is associated with an acceptable complication
rate. Cite this article:
