Abstract Background: Subcutaneous, spontaneous, complete ruptures of the Achilles tendon are usually caused indirectly by trauma associated with rapid movement. When minimally invasive Achilles tendon repair is performed, an active rehabilitation protocol can be implemented that allows for fast, measurable progress, reduced tissue atrophy, and an improved range of motion, thereby reducing pain and increasing patients’ overall physical well-being. However, overestimating the effectiveness of rehabilitative interventions can lead to arbitrary advancements in rehabilitation that significantly exceed the permitted levels of daily or professional activity. This issue can lead to various side effects and slow rehabilitation. The aim of the study was to evaluate the influence of adverse effects on objective outcomes after minimally invasive Achilles tendon repair.Methods: The study included 36 individuals with complete Achilles tendon rupture who underwent the percutaneous Ma-Griffith technique. The same rehabilitation protocol was used.Results: Five side effects were identified during rehabilitation: deformation of the repair construct (DRC), irritation of the sural nerve (SNI), morning ankle stiffness (MAS), edema of the soft tissue around the tendon (OST) and suture knots. DRC and MAS were associated with a longer time being required to achieve full ankle range of motion. SNI and OST were associated with a longer time being required to meet the criteria for dynamic training. None of the side effects were related to the isokinetic strength of the ankle plantar and dorsiflexors.Conclusions: The incidence of the assessed side effects in the postoperative period is not related to the type of activity, whether it is professional or amateur. Among the identified side effects, deformation of the regenerated shape of the heel tendon and MAS cause a delay in the recovery of full ankle range of motion. Calf nerve irritation and soft tissue swelling increase the time it takes to meet the criteria for starting dynamic training.Trial registration:The study was approved by the ethics committee of the Academy of Physical Education in Katowice (no. 13/2007)

The pandemic caused by COVID-19 has led to an unprecedented situation, forcing governments to take urgent measures and confine the population. These measures have also affected sports. Soccer competitions and training sessions were interrupted worldwide, causing the need to adapt training sessions to the new situation. The objective of this study is to observe and analyse training habits carried out during the COVID-19 confinement by Spanish professional soccer players of both sexes. An o bservational study was based on an ad-hoc telematic questionnaire during the COVID-19 state of alarm in Spain. The results showed that strength and conditioning training was of great importance in the training habits developed during the COVID-19 confinement, fundamentally that of strength and endurance capacities. Specificity was low as conditional capabilities were affected by contextual limitations. The findings of this study yielded very useful information related to the training habits of professional soccer players of both sexes and offered an unpublished reference database that could be used to address training planning at specific periods of the year (transition, vacations, emergencies, ...), with the aim of resuming competitive activity in the best conditions.

Objectives: The ruptures of the Achilles tendon (AT) are relatively common. Since there is no consensus on the best method of the repair of the AT; the treatment is determined on the preference of the surgeon and the patient. The study evaluating the cadaveric and short term clinical results done by our clinic in 2002, has shown us that arthroscopically Achilles tendon repair can be good choise in achilles tendon ruptures. Methods: Fortyfour patients who underwent arthroscopically assisted achilles tendon repair during 1997-2011 in Osmangazi University Orthopaedics and Traumatology Department were retrospectively observed. The mean follow-up time was 69,7 months. One of patients had bilateral rupture. The diagnosis was based on loss of plantar flexion strength, palpation of the gap in the tendon, and a positive Thompson test. MRI and USG were used when needed. The ruptures were left-sided in nineteen patients and right-sided in twentysix. The cause of the rupture was recreational sports activity in thirtyeight, fall from height in four, missing a step in a staircase in two. Return the regular activity, ankle range of motion as compared with the opposite side, calf circumference, and ability to walk and stand tiptoe were recorded. All patients were operated on within 2-32 days after the rupture. Thirtysix operations were performed under spinal anesthesia and eight operations were performed under general anesthesia. Tourniquet was always used. Before starting the procedure, the rupture site and location of the gap are marked. Using the common videoarthroscopic instruments, a 70 degrees scope was inserted into the AT through the stab incision made previously, and the torn ends of the tendon were visualized with plantar flexion an extension of the ankle. After the visualization of the torn ends of the tendon and repair by the technique of Ma and Griffith care was focused to contact the ends of the tendon anatomically; then the sutures were knotted. A short leg circular cast with the ankle in slight plantar flexion was applied. American Orthopaedics Foot-Ankle Society (AOFAS) score was used to evaluate the long-term results.. Results: All patients had satisfactory results that no reruptures had occurred. No significant difference in range of motion of the ankle and calf circumference between the opposite sides was observed in any patient. All patients could walk and stand on tiptoe. AOFAS mean score was 94.5 (65-100). The interval from injury to return to regular work and activities was 8-10 weeks. All the patients were able to return back to their activity level before surgery. In three patients temporary sural hypoestesia, in one patient permanent sural hipoestesia and in one patient wound enfection appeared. No sensory deficit was detected in the temporary sural hypoestesia patients after postoperative second year controls. Medical care was supported to the patient with the wound enfection and the enfection was under control in the early stages. Conclusion: In summary; arthroscopically-assisted percutaneous repair of AT appears to overcome some certain problems of open, conservative and percutaneous techniques; but the neurovascular structure damage risk especially the sural nerve remains a potent problem. Accurate knowledge of the anatomy appears to be a solution. Novel percutaneous repairs have been promising to minimize the risk of sural nerve damage.

Context: Shoulder injuries are highly prevalent in sports involving the upper extremity. Some risk factors have been identified in the literature, but consensus is still lacking. Objectives: To identify risk factors of overuse shoulder injury in overhead athletes, as described in the literature. Data Sources: A systematic review of the literature from the years 1970 to 2018 was performed using 2 electronic databases: PubMed and Scopus. Study Selection: Prospective studies, written in English, that described at least 1 risk factor associated with overuse shoulder injuries in overhead sports (volleyball, handball, basketball, swimming, water polo, badminton, baseball, and tennis) were considered for analysis. Study Design: Systematic review. Level of Evidence: Level 3. Data Extraction: Data were extracted from 25 studies. Study methodology quality was evaluated using the Modified Coleman Methodology Score. Results: Intrinsic factors, previous injury, range of motion (lack or excess), and rotator cuff weakness (isometric and isokinetic) highly increase the risk of future injuries. Additionally, years of athletic practice, body mass index, sex, age, and level of play seem to have modest influence. As for the effect of scapular dysfunction on shoulder injuries, it is still controversial, though these are typically linked. Extrinsic factors, field position, condition of practice (match/training), time of season, and training load also have influence on the occurrence of shoulder injuries. Conclusion: Range of motion, rotator cuff muscle weakness, and training load are important modifiable factors associated with shoulder injuries. Scapular dysfunction may also have influence. The preventive approach for shoulder injury should focus on these factors.

Motion Measurements

Movement of the foot is essential for human locomotion. The purpose of this paper was to quantify the range of motion of the foot as a function of age and to compare the rage of motion measurements for the foot in a laboratory coordinate system and a coordinate system fixed to the tibia. The measurements were taken in vivo using a range of motion instrument developed by Allinger (University of Calgary, Canada, 1990) from 121 subjects. The results suggest that: (1) the range of motion in general is greater for women than for men in the young adult group; (2) the range of motion in general is in the same order of magnitude for women and men in the oldest age group; and (3) the range of motion is about 8° smaller in dorsiflexion and about 8° higher in plantarflexion for women than for men in the oldest age group. It is speculated that physical activity and common shoe wear are factors influencing the age- and gender-dependent differences in range of motion. Furthermore, it has been shown that the range of motion values measured in a laboratory coordinate system and in a coordinate system fixed in the tibia are different in all directions except inversion. The differences in plantarflexion and dorsiflexion and inversion and eversion are relatively small. However, they are substantial for adduction and abduction. In all cases, the results were bigger for measurements in the laboratory coordinate system compared with the tibia coordinate system, because the movement of the lower leg was included in the measurements in the laboratory coordinate system. The data indicate that foot range of motion is different for women and men. Consequently, it is speculated that these differences may be related to possible overloading of the locomotor system, especially in sporting activities in which the loading of the foot is significant. The differences in the plantarflexion and dorsiflexion direction were assumed to influence the loading of the Achilles tendon, and it is suggested that some of the Achilles tendon problems may be predictable based on range of motion measurements.

Retrospective Comparative Study

Background: Surgeons frequently add an Achilles tendon lengthening or gastrocnemius recession to increase dorsiflexion following total ankle replacement. Previous studies have looked at the effects of these procedures on total tibiopedal motion. However, tibiopedal motion includes motion of the midfoot and hindfoot as well as the ankle replacement. The current study examined the effects of Achilles tendon lengthening and gastrocnemius recession on radiographic tibiotalar motion at the level of the prosthesis only. Methods: Fifty-four patients with an average of 25 months follow-up after total ankle replacement were divided into 3 groups: (1) patients who underwent Achilles tendon lengthening, (2) patients who had a gastrocnemius recession, (3) patients with no lengthening procedure. Tibiotalar range of motion was measured on lateral dorsiflexion-plantarflexion radiographs using reference lines on the surface of the implants. Results: Both Achilles tendon lengthening and gastrocnemius recession significantly increased tibiotalar dorsiflexion when compared to the group without lengthening. However, the total tibiotalar range of motion among the 3 groups was the same. Interestingly, the Achilles tendon lengthening group lost 11.7 degrees of plantarflexion compared to the group without lengthening, which was significant. Conclusion: Both Achilles tendon lengthening and gastrocnemius recession increased radiographic tibiotalar dorsiflexion following arthroplasty. Achilles tendon lengthening had the unexpected effect of significantly decreasing plantarflexion. Gastrocnemius recession may be a better choice when faced with a tight ankle replacement because it increases dorsiflexion without a compensatory loss of plantarflexion. Level of Evidence: Level III, retrospective comparative study.

BACKGROUND: Screening and training of professional dancers is commonly based around beliefs that a large range of turnout is more advantageous in the ballet industry. This belief leads dancers who have limited hip external rotation to compensate by forcing turnout at the knee and ankle, which has been linked to injury. OBJECTIVE: To examine if there is a difference in degree of turnout between three levels of dancers (corps, soloist, principal) in a professional classical ballet company. An additional aim was to establish average values for the range of turnout and hip rotation present in the dancers. METHODS: Forty-five professional dancers from The Australian Ballet (25 female, 20 male) participated in the study. Active and passive hip external rotation (hip ER) was measured in supine using inclinometers, and functional turnout in ballet first position (lower limb external rotation, LLER) was measured using foot traces utilising bony landmarks. Below-hip external rotation (BHER) was also calculated. RESULTS: No relationship was found among level of dancer and passive hip ER, active hip ER, LLER, and BHER. Professional dancers had on average 50.2° of passive hip ER range, 35.2° of active hip ER, and 133.6° of functional turnout position. In addition, no correlation was found between LLER and hip ER, but significant correlations were found between LLER and BHER. CONCLUSIONS: Hip rotation range of motion is similar across all levels of professional dancers. Average values for passive and active hip ER and functional turnout were established.

Extensor Tendon

Tendon xanthomatosis often accompanies familial hypercholesterolaemia, but it can also occur in other pathologic states. Of the musculoskeletal system, the Achilles tendon is the most commonly effected tendon due to xanthomatosis. Although there are previous reports for flexor tendon involvement, to our knowledge there is no report in the English literature about bilateral hand extensor tendon xanthomatosis that causes restriction in the range of motion. The case that will be presented in this report is therefore unique.

The effects of concentric contractions and passive stretching on musculotendinous stiffness and muscle activity were studied in 18 healthy human volunteers. Passive and concentric plantar flexor joint moment data were recorded on an isokinetic dynamometer with simultaneous electromyogram (EMG) monitoring of the triceps surae, real-time motion analysis of the lower leg, and ultrasound imaging of the Achilles-medial gastrocnemius muscle-tendon junction. The subjects then performed six 8-s ramped maximal voluntary concentric contractions before repeating both the passive and concentric trials. Concentric moment was significantly reduced (6.6%; P < 0.01), which was accompanied by, and correlated with ( r = 0.60–0.94; P < 0.05), significant reductions in peak triceps surae EMG amplitude (10.2%; P < 0.01). Achilles tendon stiffness was significantly reduced (11.7%; P < 0.01), but no change in gastrocnemius medialis muscle operating length was detected. The subjects then performed three 60-s static plantar flexor stretches before being retested 2 and 30 min poststretch. A further reduction in concentric joint moment (5.8%; P < 0.01) was detected poststretch at 90% of range of motion, with no decrease in muscle activity or Achilles tendon stiffness, but a significant increase in muscle operating length and decrease in tendon length was apparent at this range of motion ( P < 0.05). Thirty minutes after stretching, muscle activity significantly recovered to pre-maximal voluntary concentric contractions levels, whereas concentric moment and Achilles tendon stiffness remained depressed. These data show that the performance of maximal concentric contractions can substantially reduce neuromuscular activity and muscle force, but this does not prevent a further stretch-induced loss in active plantar flexor joint moment. Importantly, the different temporal changes in EMG and concentric joint moment indicate that a muscle-based mechanism was likely responsible for the force losses poststretch.
