This prospective study compares the outcome of
157 hydroxyapatite (HA)-coated tibial components with 164 cemented
components in the ROCC Rotating Platform total knee replacement
in 291 patients. The mean follow-up was 7.6 years (5.2 to 11). There
were two revisions for loosening: one for an HA-coated and one for
a cemented tibial component. Radiological evaluation demonstrated
no radiolucent lines with the HA-coated femoral components. A total
of three HA-coated tibial components exhibited radiolucent lines
at three months post-operatively and these disappeared after three
further months of protected weight-bearing. With HA-coated components
the operating time was shorter (p <
0.006) and the radiological
assessment of the tibial interface was more stable (p <
0.01).
Using revision for aseptic loosening of the tibial component as
the end point, the survival rates at nine years was identical for
both groups at 99.1%. Our results suggest that HA-coated components perform at least
as well as the same design with cemented components and compare
favourably with those of series describing cemented or porous-coated
knee replacements, suggesting that fixation of both components with
hydroxyapatite is a reliable option in primary total knee replacement.

Ceramic-on-metal (CoM) is a relatively new bearing
combination for total hip arthroplasty (THA) with few reported outcomes.
A total of 287 CoM THAs were carried out in 271 patients (mean age
55.6 years (20 to 77), 150 THAs in female patients, 137 in male)
under the care of a single surgeon between October 2007 and October
2009. With the issues surrounding metal-on-metal bearings the decision
was taken to review these patients between March and November 2011,
at a mean follow-up of 34 months (23 to 45) and to record pain,
outcome scores, radiological analysis and blood ion levels. The
mean Oxford Hip Score was 19.2 (12 to 53), 254 patients with 268
hips (95%) had mild/very mild/no pain, the mean angle of inclination
of the acetabular component was 44.8o (28o to
63o), 82 stems (29%) had evidence of radiolucent lines
of >
1 mm in at least one Gruen zone and the median levels of cobalt
and chromium ions in the blood were 0.83 μg/L (0.24 μg/L to 27.56 μg/L)
and 0.78 μg/L (0.21 μg/L to 8.84 μg/L), respectively. The five-year
survival rate is 96.9% (95% confidence interval 94.7% to 99%). Due to the presence of radiolucent lines and the higher than
expected levels of metal ions in the blood, we would not recommend
the use of CoM THA without further long-term follow-up. We plan
to monitor all these patients regularly. Cite this article:
Unlinked, linked and convertible total elbow
arthroplasties (TEAs) are currently available. This study is the
first to report the clinical results of the convertible Latitude
TEA. This was a retrospective study of a consecutive cohort of 63
patients (69 primary TEAs) with a mean age of 60 years (23 to 87).
Between 2006 and 2008 a total of 19 men and 50 women underwent surgery.
The mean follow-up was 43 months (8 to 84). The range of movement,
function and pain all improved six months post-operatively and either
continued to improve slightly or reached a plateau thereafter. The
complication rate is similar to that reported for other TEA systems.
No loosening was seen. Remarkable is the disengagement of the radial
head component in 13 TEAs (31%) with a radial head component implanted. Implantation of both the linked and the unlinked versions of
the Latitude TEA results in improvement of function and decreased
pain, and shows high patient satisfaction at mid-term follow-up. Cite this article:
The intra-articular injection of local anaesthetic is frequently used for pain relief after arthroscopy. There is, however, no published evidence of the analgesic effect of bupivacaine in the ankle. In a randomised, double-blind study, 35 patients undergoing arthroscopy of the ankle were allocated to receive intra-articular saline or bupivacaine. Pain was assessed using pain scores and additional analgesic requirements. Intra-articular bupivacaine had a significant analgesic effect in the immediate post-operative period, reducing pain scores and the need for additional analgesics. We recommend the use of intra-articular bupivacaine for post-operative analgesia in ankle surgery.
The outcome of surgery for recurrent lumbar disc
herniation is debatable. Some studies show results that are comparable
with those of primary discectomy, whereas others report worse outcomes.
The purpose of this study was to compare the outcome of revision
lumbar discectomy with that of primary discectomy in the same cohort
of patients who had both the primary and the recurrent herniation
at the same level and side. A retrospective analysis of prospectively gathered data was undertaken
in 30 patients who had undergone both primary and revision surgery
for late recurrent lumbar disc herniation. The outcome measures
used were visual analogue scales for lower limb (VAL) and back (VAB)
pain and the Oswestry Disability Index (ODI). There was a significant improvement in the mean VAL and ODI scores
(both p <
0.001) after primary discectomy. Revision surgery also
resulted in improvements in the mean VAL (p <
0.001), VAB (p
= 0.030) and ODI scores (p <
0.001). The changes were similar
in the two groups (all p >
0.05). Revision discectomy can give results that are as good as those
seen after primary surgery. Cite this article:
We report the clinical and radiographic outcomes
of 208 consecutive femoral revision arthroplasties performed in 202
patients (119 women, 83 men) between March 1991 and December 2007
using the X-change Femoral Revision System, fresh-frozen morcellised
allograft and a cemented polished Exeter stem. All patients were
followed prospectively. The mean age of the patients at revision
was 65 years (30 to 86). At final review in December 2013 a total
of 130 patients with 135 reconstructions (64.9%) were alive and
had a non re-revised femoral component after a mean follow-up of
10.6 years (4.7 to 20.9). One patient was lost to follow-up at six
years, and their data were included up to this point.
Re-operation for any reason was performed in 33 hips (15.9%), in
13 of which the femoral component was re-revised (6.3%). The mean
pre-operative Harris hip score was 52 (19 to 95) (n = 73) and improved
to 80 (22 to 100) (n = 161) by the last follow-up. Kaplan–Meier
survival with femoral re-revision for any reason as the endpoint
was 94.9% (95% confidence intervals (CI) 90.2 to 97.4) at ten years;
with femoral re-revision for aseptic loosening as the endpoint it was
99.4% (95% CI 95.7 to 99.9); with femoral re-operation for any reason
as the endpoint it was 84.5% (95% CI 78.3 to 89.1); and with subsidence ≥ 5
mm it was 87.3% (95% CI 80.5 to 91.8). Femoral revision with the
use of impaction allograft bone grafting and a cemented polished
stem results in a satisfying survival rate at a mean of ten years’ follow-up. Cite this article:
The October 2014 Shoulder &
Elbow Roundup360 looks at: PRP is not effective in tennis elbow; eccentric physiotherapy effective in subacromial pain; dexamethasone in shoulder surgery; arthroscopic remplissage for engaging Hill-Sach’s lesions; a consistent approach to subacromial impingement; delay in fixation of proximal humeral fractures detrimental to outcomes.
Effective analgesia after total knee arthroplasty (TKA) improves
patient satisfaction, mobility and expedites discharge. This study
assessed whether continuous femoral nerve infusion (CFNI) was superior
to a single-shot femoral nerve block in primary TKA surgery completed
under subarachnoid blockade including morphine. We performed an adequately powered, prospective, randomised,
placebo-controlled trial comparing CFNI of 0.125% bupivacaine Objectives

The optimal timing of total knee replacement
(TKR) in patients with osteoarthritis, in relation to the severity
of disease, remains controversial. This prospective study was performed
to investigate the effect of the severity of osteoarthritis and
other commonly available pre- and post-operative clinical parameters
on the clinical outcome in a consecutive series of cemented TKRs.
A total of 176 patients who underwent unilateral TKR were included
in the study. Their mean age was 68 years (39 to 91), 63 (36%) were
male and 131 knees (74%) were classified as grade 4 on the Kellgren–Lawrence
osteoarthritis scale. A total of 154 patients (87.5%) returned for
clinical review 12 months post-operatively, at which time the outcome
was assessed using the Knee Society score. A low radiological severity of osteoarthritis was not associated
with pain 12 months post-operatively. However, it was significantly
associated with an inferior level of function (p = 0.007), implying
the need for increased focus on all possible reasons for pain in
the knee and the forms of conservative treatment which are available
for patients with lower radiological severity of osteoarthritis. Cite this article:
This review examines the future of total hip arthroplasty, aiming to avoid past mistakes
Resurfacing of the humeral head is commonly used
within the UK to treat osteoarthritis (OA) of the shoulder. We present
the results of a small prospective randomised study of this procedure
using the Global CAP prosthesis with two different coatings, Porocoat
and DuoFix hydroxyapatite (HA). We followed two groups of ten patients
with OA of the shoulder for two years after insertion of the prosthesis
with tantalum marker beads, recording pain, Constant–Murley and
American Shoulder and Elbow Surgeons (ASES) outcome scores, and
using radiostereometric analysis to assess migration. The outcomes
were similar to those of other series, with significant reductions
in pain (p = 0.003) and an improvement in the Constant (p = 0.001)
and ASES scores (p = 0.006). The mean migration of the prosthesis
three months post-operatively was 0.78 mm (0.51 to 1.69) and 0.72
mm (0.33 to 1.45) for the Porocoat and DuoFix groups, respectively.
Analysis of variance indicated that the rate of migration reached
a plateau after three months post-operatively in both groups. At
follow-up of two years the mean migration was 1 mm ( The addition of a coating of HA to the sintered surface does
not improve fixation of this prosthesis. Cite this article:
Local corticosteroid infiltration is a common practice of treatment
for lateral epicondylitis. In recent studies no statistically significant
or clinically relevant results in favour of corticosteroid injections
were found. The injection of autologous blood has been reported
to be effective for both intermediate and long-term outcomes. It
is hypothesised that blood contains growth factors, which induce
the healing cascade. A total of 60 patients were included in this prospective randomised
study: 30 patients received 2 ml autologous blood drawn from contralateral
upper limb vein + 1 ml 0.5% bupivacaine, and 30 patients received
2 ml local corticosteroid + 1 ml 0.5% bupivacaine at the lateral
epicondyle. Outcome was measured using a pain score and Nirschl
staging of lateral epicondylitis. Follow-up was continued for total
of six months, with assessment at one week, four weeks, 12 weeks
and six months.Objectives

The Essex-Lopresti injury (ELI) of the forearm
is a rare and serious condition which is often overlooked, leading
to a poor outcome. The purpose of this retrospective case study was to establish
whether early surgery can give good medium-term results. From a group of 295 patients with a fracture of the radial head,
12 patients were diagnosed with ELI on MRI which confirmed injury
to the interosseous membrane (IOM) and ligament (IOL). They were
treated by reduction and temporary Kirschner (K)-wire stabilisation
of the distal radioulnar joint (DRUJ). In addition, eight patients
had a radial head replacement, and two a radial head reconstruction. All patients were examined clinically and radiologically 59 months
(25 to 90) after surgery when the mean Mayo Modified Wrist Score
(MMWS) was 88.4 (78 to 94), the mean Mayo Elbow Performance Scores
(MEPS) 86.7 (77 to 95) and the mean disabilities of arm, shoulder
and hand (DASH) score 20.5 (16 to 31): all of these indicate a good outcome. In case of a high index of suspicion for ELI in patients with
a radial head fracture, we recommend the following: confirmation
of IOM and IOL injury with an early MRI scan; early surgery with
reduction and temporary K-wire stabilisation of the DRUJ; preservation
of the radial head if at all possible or replacement if not, and
functional bracing in supination. This will increase the prospect
of a good result, and avoid the complications of a missed diagnosis
and the difficulties of late treatment. Cite this article:
The June 2014 Knee Roundup360 looks at: acute repair preferable in hamstring ruptures; osteoarthritis a given in ACL injury, even with reconstruction?; chicken and egg: patellofemoral dysfunction and hip weakness; meniscal root tears as bad as we thought; outcomes in the meniscus; topical NSAIDs have a measurable effect on synovitis; nailing for tibial peri-prosthetic fracture.
The aim of this study was to examine the functional
outcome at ten years following lateral closing wedge high tibial osteotomy
for medial compartment osteoarthritis of the knee and to define
pre-operative predictors of survival and determinants of functional
outcome. 164 consecutive patients underwent high tibial osteotomy between
2000 and 2002. A total of 100 patients (100 knees) met the inclusion
criteria and 95 were available for review at ten years. Data were
collected prospectively and included patient demographics, surgical
details, long leg alignment radiographs, Western Ontario and McMaster Universities
osteoarthritis index (WOMAC) and Knee Society scores (KSS) pre-operatively
and at five and ten years follow-up. At ten years, 21 patients had been revised at a mean of five
years. Overall Kaplan–Meier survival was 87% (95% confidence interval
(CI) 81 to 94) and 79% (95% CI 71 to 87) at five and ten years,
respectively. When compared with unrevised patients, those who had
been revised had significantly lower mean pre-operative WOMAC Scores
(47 (21 to 85) This study has shown that improved survival is associated with
age <
55 years, pre-operative WOMAC scores >
45 and, a BMI <
30. In patients over 55 years of age with adequate pre-operative
functional scores, survival can be good and functional outcomes
can be significantly better than their younger counterparts. We
recommend the routine use of pre-operative functional outcome scores
to guide decision-making when considering suitability for high tibial osteotomy. Cite this article:
The October 2014 Trauma Roundup360 looks at: proximal humeral fractures in children; quadrilateral surface plates in transverse acetabular fractures; sleep deprivation and poor outcomes in trauma; bipolar hemiarthroplasty; skeletal traction; forefoot fractures; telemedicine in trauma; ketamine infusion for orthopaedic injuries; and improved functional outcomes seen with trauma networks.
We identified a group of patients from the Swedish
Arthroplasty Register who reported no relief of pain or worse pain
one year after a total knee replacement (TKR). A total of two different
patient-reported pain scores were used during this process. We then
evaluated how the instruments used to measure pain affected the
number of patients who reported no relief of pain or worse pain,
and the relative effect of potential risk factors. Between 2008 and 2010, 2883 TKRs were performed for osteoarthritis
in two Swedish arthroplasty units. After applying exclusion criteria,
2123 primary TKRs (2123 patients) were included in the study. The
Knee injury and Osteoarthritis Outcome Score (KOOS) and a Visual
Analogue Scale (VAS) for knee pain were used to assess patients pre-operatively
and one year post-operatively. Only 50 of the 220 patients (23%) who reported no pain relief
on either the KOOS pain subscale or the VAS for knee pain did so
with both of these instruments. Patients who reported no pain relief
on either measure tended to have less pain pre-operatively but a
higher degree of anxiety. Charnley category C was a predictor for
not gaining pain relief as measured on a VAS for knee pain. The number of patients who are not relieved of pain after a TKR
differs considerably depending on the instrument used to measure
pain. Cite this article:
