We examined biopsy specimens obtained during surgery on 115 patients with complete rotator cuff rupture. The vascularised connective tissue covering the area of rupture and the proliferating cells in the fragmented tendons reflected more of the features of
Allografts of intact cartilage, isolated chondrocytes and cultured chondrocytes taken from the epiphysial growth-plate and from the articular surface of immature rabbits were inserted into full thickness defects in the tibial articular surface of 160 mature rabbits. In the contralateral knees, which were used as controls, similar defects were made but no grafts were inserted. Grafts were followed up for periods of up to one year after transplantation. Both intact articular and intact growth-plate grafts produced significantly better

We compared two treatments for tears of the rotator cuff of 1 to 4 cm in size. One group of 22 patients had an arthroscopic subacromial decompression and rotator-cuff debridement; the other comparable group of 23 patients had open
Fractures of the atlas constitute 4% to 12% of all bony injuries of the cervical spine; most are treated successfully by a cervical orthosis. Nonunion may be associated with neck or scalp pain on movement and is treated conventionally by some form of craniocervical fusion, which restricts head movement. The authors describe a case in which direct

1. The results of operation in sixty-three patients with rupture of the rotator cuff of the shoulder have been reviewed. 2. In seventeen patients the classical delto-pectoral route was found to give poor access and mediocre results. 3. In forty-six patients a superior approach along the supraspinatus fossa and through the divided acromion process was found to give excellent access and to permit lateral advancement of the supraspinatus muscle in order to enable wide gaps to be closed. With this improved surgical access the proportion of good results has been doubled. 4. It is suggested that when a case of rupture of the cuff, confirmed by arthrography, fails to respond to physiotherapy, operative

The effects of splintage, suture and excision of the tendon sheath on the healing of incompletely transected flexor tendons in the rabbit have been evaluated separately and in various combinations. When all procedures were done together,
Lesions within the articular cartilage layer of synovial joints do not heal spontaneously. Some
Sixty-five knees were subjected to a kinematic analysis using the instant-centre technique in order to determine the effect of deficiency of the anterior cruciate ligament on the biomechanics of active movement in the knee. The instant-centre pathway in acute ruptures of the anterior cruciate ligament was found to have a specific abnormality. This corresponded with a positive pivot-shift sign, but was present even when that sign was not clinically detectable. Primary
The aim was to compare long-term patient-reported outcome measures (PROMs) after operative and nonoperative treatment of acute Achilles tendon rupture in the context of a randomized controlled trial. PROMs including the Short Musculoskeletal Function Assessment (SMFA), Achilles Tendon Total Rupture Score (ATRS), EuroQol five-dimension (EQ-5D), satisfaction, net promoter score and data regarding re-rupture, and venous thromboembolic rates were collected for patients randomized to receive either operative or nonoperative treatment for acute Achilles tendon rupture in a previous study. Of the 80 patients originally randomized, 64 (33 treated surgically, 31 nonoperatively) patients were followed up at a mean of 15.7 years (13.4 to 17.7).Aims
