Tendinitis in golf.

The term tendinitis has been used in a universal fashion to describe a variety of pathologic conditions. This article examines the pathology of tendon failure. The anatomy of the tendon and the spectrum of tendon injuries are discussed. Histologic evaluation of injured tendons usually reveals areas of tendinosis, or tendon degeneration, with an occasional inflammatory infiltration the paratenon, the outer connective tissue lining layer. A variety of treatment options are presented.

Alabama sports medicine experience with isolated and combined posterior cruciate ligament injuries.

Injuries to the posterior cruciate ligament (PCL) are an uncommon but significant instability pattern that eventually deteriorates the articular surface of the PLC-deficient knee. Although controversy persists regarding the appropriate treatment for the isolated PCL tear, patients with combined ligament injuries are best served by reconstruction of the PCL and surgical correction of the other injured tissues. The authors outline their experience with these complex ligamentous derangements.

Posterior cruciate ligament reconstruction with patellar tendon autograft.

Although the management of the PCL-injured knee remains controversial, there is a group of patients who will develop accelerated traumatic arthritis in whom surgical intervention is warranted. PCL reconstruction with a patellar tendon graft can reliably restore objective stability in over 90% of patients. Strict attention to detail, however, especially with respect to tunnel placement, is necessary to insure success.

Combined posterior cruciate ligament injuries.

Management of posterior cruciate ligament injuries combined with other ligamentous knee injuries must begin with an understanding of the normal anatomy and biomechanics of the knee. Careful physical examinations and judicious use of ancillary tests allow delineation of the extent of knee injury. Each combined injury can then be approached with an organized and specific plan for reconstruction, optimizing knee stability and function.

Quadriceps muscular strength after removal of the central third patellar tendon for contralateral anterior cruciate ligament reconstruction surgery: a case study.

Surgical reconstruction of the anterior cruciate ligament (ACL) using a patellar tendon autograft is a common orthopaedic procedure. Complications such as arthrofibrosis, patellar fracture, significant donor site pain, and quadriceps muscle weakness can occur from this procedure. Previous studies have not documented the effects of isolated graft procurement without concomitant ligamentous reconstruction on the donor extremity. This case study documents the clinical outcome results of an individual who underwent a central one-third graft harvest from his contralateral uninjured knee for an ACL graft of his injured ACL-deficient knee. The results indicate that at 4 months following graft procurement, the knee extensors were equal to the preoperative isokinetic test results of that leg. In addition, the patient exhibited full range of motion and no patellofemoral complaints of dysfunction. At 12 months postsurgery, the graft donor leg was 5-9% stronger than the preoperative test results. The results of this case study suggest that isolated harvesting of a 10-mm central patellar tendon free graft may not result in significant quadriceps muscle weakness or contribute to donor site pain.

Back injuries in college athletes.

Frequency and types of back injuries sustained by intercollegiate athletes were determined by examining medical records of 4,790 athletes that competed in 17 varsity sports over a 10-year period. These athletes sustained 333 back injuries, an injury rate of 7 per 100 participants. Injury rates were significantly higher in football and gymnastics, and 80% of the injuries occurred in practice, 6% in competition, and 14% during preseason conditioning. Muscle strains occurred with much greater frequency than other types of injuries, and acute back injuries were much more prevalent (59%) than overuse injuries (12%) or injuries associated with pre-existing conditions (29%).

Diagnosis of acute and chronic anterior cruciate ligament tears.

The diagnosis of acute and chronic injuries of the ACL has been reviewed. Attention has been given to the history, physical examination, and other diagnostic tools available for evaluation of the ligamentous injury. Clinical correlations have been highlighted. Finally, our recommendations for surgical intervention have been presented.

Acute tears of the anterior cruciate ligament. Surgical versus conservative treatment.

In a prospective eight-year study comparing surgical and conservative treatment of acute tears of the anterior cruciate ligament, ninety-two patients in whom a tear had been confirmed either by arthroscopy or by arthrotomy were treated and could be followed. The choice of treatment was determined entirely by whether the result of a pivot-shift test was graded as absent, trace, or mild (non-operative treatment) or as moderate or severe (surgical treatment). Surgical treatment consisted of primary repair of the torn ligament and augmentation with a patellar tendon graft. Twenty-two patients were treated non-operatively, and the results were evaluated after twenty-four to eighty-two months (average, forty-eight months). Seventy patients were treated surgically, and fifty-two of them (approximately 70 per cent) returned for follow-up after twenty-four to 100 months (average, forty-eight months); an additional eighteen patients answered a questionnaire. In the non-operative group, about half of the results were graded as excellent or good and half, as fair or a failure. In the surgical group, all but two of the patients had an excellent or a good result; two patients had a fair result. No result was graded as a failure. The results of this study suggest that when the pivot-shift test is not strongly positive, half of the patients will do reasonably well after treatment with a non-operative program of functional rehabilitation. The patients in this study who had a more unstable knee had far better results after a repair and augmentation procedure than have been previously reported after primary repair alone.

Expanding applications for the Herbert scaphoid screw.

A distinctive new bone screw developed for the management of scaphoid fractures and nonunions promises to have expanding applicability. Its utilization for osteochondral fractures, small joint arthrodeses, osteochondritic lesions, and fractures involving small bones is described. Its unique design affords significant advantages over more conventional management techniques of these problems.

Intra-articular reconstruction of the anterior cruciate ligament.

In this article, the author provides criteria for the recommendation of surgical intervention in acute and chronic anterior cruciate ligament insufficiency and describes various intra-articular procedures for both conditions. Intra-articular reconstruction of the anterior cruciate ligament with a vascularized patellar tendon graft is described in detail, as are the excellent results achieved with this procedure over the past 8 years.

Treatment of knee joint instability secondary to rupture of the posterior cruciate ligament. Report of a new procedure.

For the past five years we have attempted to correct knee instability due to rupture of the posterior cruciate ligament with a procedure that employs a free graft of one-third of the patellar tendon with its tibial and patellar attachments. This procedure was done for chronic instability in thirty-three patients and was combined with primary repair of an acute mid-substance tear of the posterior cruciate ligament in fifteen patients. Moderate to severe articular injury of the medial femoral condyle was found at operation in 48 per cent of the patients with chronic injury. Seventy-one per cent of the patients for whom the interval between injury and ligament reconstruction was two to four years, and 90 per cent of those for whom the interval was more than four years, showed articular injury of the medial femoral condyle. Only 31 per cent of the patients, however, had preoperative radiographic findings that indicated femoral articular damage. Twenty-three of the twenty-five patients with a minimum follow-up of two years returned for evaluation. All of the ten patients who had had a repair and reconstruction of an acute ligament injury (whose average follow-up was forty-one months) had a static and functional result that was graded as good or excellent. Of the thirteen patients for whom surgery was done for chronic instability (whose average follow-up was thirty-one months), the over-all static and functional result was graded as good or excellent in eleven. These results indicate that the use of one-third of the patellar tendon for reconstruction in patients with acute mid-substance tears as well as in patients with symptomatic chronic instability of the posterior cruciate ligament is an effective procedure for achieving static and functional stability of the knee.
