Randomized Controlled Trial Comparative Study Clinical TrialSurgical treatment of resistant tennis elbow. A prospective, randomised study comparing decompression of the posterior interosseous nerve and lengthening of the tendon of the extensor carpi radialis brevis muscle.
We compared decompression of the posterior interosseous nerve (PIN) and lengthening of the distal tendon of the extensor carpi radialis brevis (ECRB) for treatment of tennis elbow in a randomised trial of 28 patients. Fourteen underwent decompression of PIN and 14, lengthening of ERCB. The groups did not differ significantly with regard to age, sex and work activities. ⋯ The outcome after the primary operation was successful in 50% of the PIN group and in 43% of the ECRB group. Four of the 5 patients with a poor outcome were reoperated in the former group and 3 in the latter. The overall outcome after a mean follow-up of 31 months after the primary operation was successful in 60% of the cases.

Case ReportsNon-union of the capitate with associated triangular fibrocartilage tear.
We report a case of a 19-year-old boy who presented with a painful wrist 3 months after a fall. Plain radiographs demonstrated a non-union of a capitate fracture which was unrecognised at the time of injury. Magnetic resonance imaging confirmed the diagnosis and also demonstrated a tear of the triangular fibrocartilage complex. This combination of injuries has not been previously described.

Knee and ankle: human joints with different susceptibility to osteoarthritis reveal different cartilage cellularity and matrix synthesis in vitro.
Clinical experience shows that symptoms and pathological changes of primary osteoarthritis (OA) are more frequent and severer in the knee than in the ankle joint. The different anatomy of both weight-bearing joints implies that biomechanical differences may contribute to their varying susceptibility to OA. This study aims at elucidating other non-biomechanical factors to explain these fundamental differences in secondary OA prevalence. ⋯ In addition, cartilage from the ankle joint is significantly more cellular than cartilage from the knee joint. In general, ankle chondrocytes synthesize more proteoglycans (PGs) and collagens than knee chondrocytes, and deep zone chondrocytes more than superficial zone chondrocytes. The biochemical properties of chondrocytes of the ankle and knee joints differ significantly and might play an important role in the pathogenesis of OA.

Correlation between the Q angle and the patella position: a clinical and axial computed tomography evaluation.
The purpose of this study was to evaluate the significance of the Q angle with respect to the patella position. Fifty-six knee joints of 34 patients (15 bilateral) with chronic patellofemoral pain were prospectively evaluated. All patients were examined by the same orthopaedic surgeon (R. ⋯ Similar results were found in patients with pain only on one side. In conclusion, there is no significance between the Q angle and the position of patella. The diagnostic relevance of the Q angle could not be established.

Functional results after anterior cruciate ligament reconstruction using the patellar ligament bone-tendon-bone technique.
This study evaluates the outcome after surgical repair of the cruciate ligament in 129 patients (physical examination plus questionnaire) and another 49 patients (questionnaire only) after a mean interval of 3.2 years. A modified Lysholm score and the OAK score together with KT 1000 arthrometry were used. ⋯ The overall OAK objective score was good or excellent in 81%. Elongation as measured by KT 1000 arthrometry was 1.0 mm (67 N) and 1.2 mm (90 N) on average compared with the contralateral knee.
