BACKGROUND: Tendon disorders are common problems in sports and are known to be difficult to treat. Only limited information is available concerning treatment of proximal hamstring tendinopathy. To the authors' knowledge, no histopathologic findings of proximal hamstring tendinosis have been published. HYPOTHESIS: Surgery (semimembranosus tenotomy and exploration of the sciatic nerve) is an effective treatment for proximal hamstring tendinopathy. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A total of 103 cases of proximal hamstring tendinopathy in athletes (58 men, 32 women; 13 bilateral operations) with surgical treatment were included. The cases were retrospectively analyzed, and a 4-category rating system was used to evaluate the overall result. At the follow-up, the patients were asked about possible symptoms and their return to sports. Biopsy samples from 15 of the operated tendons were taken and analyzed by a pathologist. RESULTS: The average follow-up was 49 months (range, 12-156 months). The result was evaluated to be excellent in 62 cases, good in 30, fair in 5, and poor in 6. After surgery, 80 of the 90 patients were able to return to the same level of sporting activity as before the onset of the symptoms. This took a mean of 5 months (range, 2-12 months). Typical morphologic findings of tendinosis were found in all biopsy specimens. CONCLUSION: Given the good functional outcome and low complication rate, the authors present surgical treatment as a valuable option in proximal hamstring tendinopathy if conservative treatment fails.

BACKGROUND: Complete proximal hamstring avulsions can cause considerable morbidity and are often associated with significant functional loss. HYPOTHESIS: Early surgical treatment leads to better results than does surgery in the chronic phase. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Forty-one patients (21 men and 20 women) with a complete proximal hamstring avulsion were included. The cases were retrospectively analyzed, and a 4-category rating system was used to evaluate the overall result of the surgical treatment. RESULTS: The mean follow-up was 37 months (range, 12-72 months). Nineteen patients were rated as having an excellent result and 10 patients a good result. In 5 patients, the result was classified as moderate and in 7 patients poor. In the patients with an excellent or good result, the delay from the injury to surgery averaged 2.4 months, whereas in patients with a moderate or poor result, the delay averaged 11.7 months. The difference was statistically significant (P < .001). CONCLUSION: Excellent or good results can often be expected with surgery, and considerable improvement of symptoms may be achieved even in chronic cases. According to the results, early operative treatment in complete proximal avulsions of the hamstring muscles gives better results than does late surgery and is therefore recommended.

BACKGROUND: Total or near-total rupture of the pectoralis major muscle is a rare injury. Fewer than 200 cases have been reported in literature, many of them in single case reports. There is discrepancy regarding whether this kind of injury should be treated operatively. HYPOTHESIS: Early surgical treatment is necessary to obtain optimal functional recovery following total or near-total ruptures of the pectoralis major muscle. STUDY DESIGN: A case series of 33 operatively treated pectoralis major ruptures combined with a meta-analysis of the previously published cases in the English literature. METHODS: The authors have retrospectively analyzed 33 operatively treated cases of total or near-total ruptures of the pectoralis major muscle. They have also analyzed the previously published cases and the final outcomes of their treatment. The difference in outcome between groups of acute operation, delayed operation, and conservative treatment in both their own material and meta-analysis was statistically analyzed. RESULTS: Both the case series and the analysis of the cases from the literature showed that early operative treatment is associated with better outcome than delayed treatment. The delayed operation was associated with better outcome than the conservative treatment. CONCLUSION: Early surgical treatment by anatomic repair gives the best results in the treatment of total and near-total ruptures of the pectoralis major muscle.

BACKGROUND: The cause, pathogenesis, and appropriate treatment of meniscal cysts remain controversial. PURPOSE: We wanted to evaluate the results of treatment of meniscal cysts with two different operative procedures. STUDY DESIGN: Prospective cohort study. METHODS: Two different operative procedures were compared. Sixteen patients (group 1) had an open excision of the cyst performed in addition to arthroscopic examination of the knee. Nineteen patients (group 2) were treated entirely arthroscopically. The postoperative treatment course was the same for both groups. The mean length of follow-up was 33 months. RESULTS: The results were excellent or good in 86% of the patients (30 of 35) and were equally good for both procedures. Patients with degenerative changes of the knee joint seemed to have a less favorable outcome. CONCLUSIONS: Good or excellent results can be expected from either open or arthroscopic treatment of meniscal cysts. [ABSTRACT FROM AUTHOR]

We analyzed the complications after surgical treatment of Achilles tendon overuse injuries in 432 consecutive patients. The patients underwent a clinical examination 2 weeks, and 1, 2, and 5 months after the surgery. If a complication appeared, the patient was followed up clinically for at least 1 year. There were 46 (11%) complications in the 432 patients: 14 skin edge necroses, 11 superficial wound infections, 5 seroma formations, 5 hematomas, 5 fibrotic reactions or scar formations, 4 sural nerve irritations, 1 new partial rupture, and 1 deep vein thrombosis. Fourteen patients with a complication had reoperations: four patients for skin edge necrosis, two for superficial wound infection, two for seroma formation, one for hematoma formation, two for fibrotic reaction or scar formation, two for sural nerve irritation, and one for a new partial rupture. About every 10th patient treated surgically for chronic Achilles tendon overuse injury suffered from a postoperative complication that clearly delayed recovery. However, the majority of patients with a complication healed and returned to their preinjury levels of activity. To reduce this morbidity, it is essential that the surgeon be continuously aware of the possibility of postoperative complications and use proper surgical techniques. [ABSTRACT FROM AUTHOR]

We investigated the prognosis of low-back pain and the association of clinical symptoms and anatomic findings among young athletes. Consecutive patients, aged between 12 and 18 years, who had low-back pain that had interfered with their training for at least 4 weeks were included in the case series. All the patients participated in a standardized interview and clinical examination, and plain radiographs and magnetic resonance images were also obtained. Most patients also participated in technetium bone scan examination. In 15 out of 19 subjects there were anatomic abnormalities that corresponded with the location and type of clinical symptoms. Twelve subjects had changes in the disk-vertebral end plate complex and eight had a positive bone scan indicative of posterior vertebral arch stress reaction. Six out of eight boys and two out of 11 girls had stress reaction (P = 0.043). Restriction of painful activities was recommended to all subjects, restriction of activities and the use of a dynamic low-back brace for the first 3 months was recommended to patients with posterior vertebral arch stress reaction. The self-reported intensity of low-back pain (scale 0-100) among all the patients was 69 +/- 16 (mean +/- SD) at baseline and 18 +/- 21 at the 1-year follow-up (P < 0.0001). In conclusion, the reasons for prolonged back pain among young athletes are usually established by imaging studies. A knowledge of anatomic abnormalities may help in tailoring training programmes and avoiding the progression of changes during growth. Simple restriction of painful activities usually leads to good recovery. [ABSTRACT FROM AUTHOR]

We present a series of 19 avulsions of the distal tendon of the biceps brachii muscle after a follow-up of 2 to 11 years. Ten patients with delayed diagnosis and treatment (3 weeks to 5 months) were compared with nine patients treated early (within 8 days after injury). Excellent or good results at follow-up were obtained in 9 of 10 patients in the delayed-treatment group and in all 9 patients in the early-treatment group. Nine of 10 patients in the delayed-treatment group and all patients in the early-treatment group had been able to return to their preinjury levels of activity. For reference, a meta-analysis of 147 cases reported previously was performed. Ninety percent of the patients treated with an anatomic reinsertion had excellent or good results after an average follow-up of 3 years, while similar results after 3 years were seen in 60% of the patients who had nonanatomic tendon reinsertion and in 14% of the patients who were treated nonoperatively. The delay of up to 3 years between injury and anatomic reinsertion had not compromised the result. From these data we concluded that anatomic reinsertion of the avulsed distal biceps tendon to the radius is the preferred treatment in acute as well as chronic injuries. [ABSTRACT FROM AUTHOR]

There are only a few epidemiological studies on the incidence of Achilles tendon (AT) ruptures. These show an increase in incidence in the West during the past few decades. The main reason is probably the increased popularity of recreational sports among middle-aged people. Ball games constitute the cause of over 60% of AT ruptures in many series. The 2 most frequently discussed pathophysiological theories involve chronic degeneration of the tendon and failure of the inhibitory mechanism of the musculotendinous unit. There are reports of AT ruptures related to the use of corticosteroids, either systemically or locally, but the role of corticosteroids in large patient series is marginal. In addition, recent studies do not confirm earlier findings of blood group O dominance in patients with AT rupture. Comparable series have been published with surgical versus nonsurgical treatment and postoperative cast immobilisation versus early functional treatment. Although conservative treatment has its own supporters, surgical treatment seems to have been the method of choice in the late 1980s and the 1990s in athletes and young people and in cases of delayed ruptures. Early ruptures in non-athletes can also be treated conservatively. In small series of compliant, well motivated patients, functional postoperative treatment has been reported to be well tolerated, safe and effective. The lack of a universal, consistent protocol for subjective and objective evaluation of AT ruptures has prevented any direct comparison of the results. The results have been often assessed according to the criteria of Lindholm or Percy and Conochie, but no scoring is available for the analysis. We assessed a new scoring method and analysed the prognostic factors related to the results. There is also no single, uniformly accepted surgical technique. Although early ruptures have been treated successfully with simple end-to-end suture, many authors have combined simple tendon suture with plastic procedures of various types. No randomised study comparing simple suture technique and repair with augmentation could be found in the literature. The major complaint against surgical treatment has been the high rate of complications. Most are minor wound complications, which delay improvement but do not influence the final outcome. Major complications are rare, but often difficult to treat with minor procedures. For instance, large postoperative skin and soft tissue defects in the Achilles region can be treated successfully with a microvascular free flap reconstruction. The complications of conservative treatment include mostly reruptures and residual lengthening of the tendon, which may result in significant calf muscle weakness. It has been postulated that a physically inactive lifestyle leads to a decrease in tendon vascularisation, while maintenance of a continuous level of activity counteracts the structural changes within the musculotendinous unit induced by inactivity and aging. Proper warm-up and stretching are essential for preventing musculotendinous injuries, but improper or excessive stretching or warming-up can predispose to these injuries. [ABSTRACT FROM AUTHOR]
