Graft hypertrophy is the most common complication of periosteal autologous chondrocyte implantation (p-ACI). ⋯ The mb-ACI technique does not lead to graft hypertrophy requiring treatment as opposed to classic p-ACI. The frequency of occurrence of graft hypertrophy after p-ACI and mb-ACI is comparable. Graft hypertrophy can be considered as a temporary excessive growth of regenerative cartilage tissue rather than a true graft hypertrophy. It is therefore usually not a persistent or systematic complication in the treatment of circumscribed cartilage defects with mb-ACI.

Randomized Controlled Trial Comparative Study
Traumatic patellar dislocation: nonoperative treatment compared with MPFL reconstruction using patellar tendon.
Over the long term, acute patellar dislocations can result in patellar instability, with high recurrence rates after nonoperative treatment. ⋯ Treatment with MPFL reconstruction using the patellar tendon produced better results, based on the analyses of posttreatment recurrences and the better final results of the Kujala questionnaire after a minimum follow-up period of 2 years.

Most people have not returned to their preinjury level of sports participation at 12 months after anterior cruciate ligament (ACL) reconstruction surgery. Twelve months' follow-up may be too early to assess return-to-sport outcomes accurately. ⋯ Less than 50% of the study sample had returned to playing sport at their preinjury level or returned to participating in competitive sport when surveyed at 2 to 7 years after ACL reconstruction surgery. Return to the preinjury level of sport at 12 months after surgery was not predictive of participation at the preinjury level in the medium term, which suggests that people who return to sport within 12 months may not maintain their sports participation.

Comparative Study
Initial fixation strength of transosseous-equivalent suture bridge rotator cuff repair is comparable with transosseous repair.
The outcome of rotator cuff repair correlates with tendon healing. Early studies of arthroscopic rotator cuff repair demonstrate lower healing rates than traditional open techniques. Transosseous-equivalent repair techniques (suture bridge) were developed to improve the initial fixation strength. ⋯ Arthroscopic techniques can achieve initial fixation strength comparable with traditional TO techniques performed without suture anchors.

Massive irreparable rotator cuff tears in patients without advanced glenohumeral arthritis can pose a challenge to surgeons. Numerous management strategies have been utilized, and studies have shown varied results with regard to shoulder pain, range of motion, strength, and overall function. ⋯ In our series of carefully selected candidates, all patients demonstrated a significant improvement in pain, range of motion, and strength. Subjective outcome measures, including mean ASES and SF-12 scores, also demonstrated significant improvement at an average 3-year follow-up.
