Background and Purpose. Despite a successful surgical procedure, deficits in muscle strength and physical function are documented 1-2 years after total hip replacement (THR). There is a lack of evidence concerning which rehabilitation strategy is the most effective after THR. The purpose of this pilot study was to investigate the feasibility of an earlyinitiated intensified, home-based training regime and to form the basis of future studies with regard to exercises, outcome measures and power calculations. Methods. The trial is a single-blinded, cluster-randomized controlled trial performed at an orthopaedic physiotherapy department in a public hospital in Denmark. A consecutive sample of 46 patients undergoing primary THR surgery for osteoarthritis between September 2008 and January 2009 was included. Forty-four patients completed the trial (96% follow-up). Participants were randomly assigned to an intervention group (IG, n = 23) receiving 12 weeks of intensified exercises (e.g. rubber band resistance) or a control group (CG, n = 21) receiving standard rehabilitation exercises without external resistance. The outcome measurements were maximal gait speed, isometric hip abductor muscle strength, one-legged stance, health-related quality of life (EuroQol-5 Dimensions), patient satisfaction, and patient-evaluated function, stiffness and pain (Western and Ontario McMasters University Osteoarthritis Index). Results. There were significant increases in both groups in all the measurements during the 12 weeks of exercises. All participants in the IG were satisfied or very satisfied with the exercises compared with 85% in the CG (P = 0.095). In the IG, four participants (17.4%) had difficulties when performing the intensified exercises at home. Hip abduction strength was significantly weaker in the leg operated compared with the leg not operated on after the intervention in both groups (P < 0.01). Conclusion. This pilot study indicates that the majority of THR patients tolerated early-initiated intensified exercises without additional pain and with high patient satisfaction. It seems that some of the patients need supervision to perform intensified exercises.
We report the feasibility of day-case THA. Safety, complications and overall patient acceptance were satisfactory. Light spinal anaesthesia facilitated quick transit through postanaesthesia care unit to early mobilisation. Support persons and patient education may play a part in high patient acceptance of day-case surgery.
Although histology data favour the view of a degenerative nature of tendinopathy, indirect support for inflammatory reactions to loading in affected tendons exists. The purpose of the present study was to elucidate whether inflammatory signalling responses after acute mechanical loading were more pronounced in tendinopathic versus healthy regions of human tendon and if treatment with non-steroidal anti-inflammatory medications (NSAID's) reduces this response. Twenty-seven tendinopathy patients (>6 months) were randomly assigned to a placebo (n = 14) or NSAID (Ibumetin NYCOMED GmbH Plant Oranienburg Germany (600 mg) × 3/day/1 week) group (n = 13) in a double-blinded-fashion. Tendon biopsies were taken from the painful and a healthy region of the same tendon 2 h after 1 h running. Gene-expression of several targets was analysed in the sampled Achilles tendon biopsies. The mRNA for TGF-β, collagen-I and collagen-III were significantly higher expressed, and decorin, CTGF, IL-6 and IL-10 were significantly lower expressed in the tendinopathic versus healthy tendon area. Only IL-10 was lower in expression in experiments with NSAID administration, while all other determined parameters were unaffected by NSAID. All ultrasonographic outcomes were unchanged in response to acute exercise and not influenced by NSAID. The signalling for collagen and TGF-beta was upregulated after acute loading in tendinopathic tendon. In contrast to the hypothesis, inflammatory signalling was not exaggerated in tendinopathic tendon 2 h after acute mechanical loading.
