Lateral epicondylitis, also known as “tennis elbow,” is a degenerative disorder of the common extensor origin of the lateral humeral epicondyle. The mainstay of treatment is non-operative and includes physiotherapy, activity modification, bracing, nonsteroidal anti-inflammatory drugs, and injections. There is a subgroup of patients however who do not respond to non-operative measures and require operative intervention. We conducted a retrospective review of prospectively collected data to assess whether the introduction of PRP injections for lateral epicondylitis led to a reduction in patients subsequently undergoing surgical release.Introduction
Methods
The indication for rotator cuff repair in elderly patients is controversial. Consecutive patients over the age of 70 years, under the care of a single surgeon, receiving an arthroscopic rotator cuff repair were reviewed. Predominantly, a single row repair was performed using one (34 cases) or two (30) 5mm Fastin, double-loaded anchors. Double-row repair was performed in four cases. Subacromial decompression and treatment of biceps pathology were performed as necessary. Data were collected from medical records, digital radiology archives and during clinic appointments. Pain, motion, strength and function were quantified with the Constant-Murley Shoulder Outcome Score, administered pre operatively and at 1-year post operatively. Ultrasound scans were performed at one year to document integrity of the repair. Sixty-nine arthroscopic cuff repairs were identified in 68 patients. The mean age was 77 years (70–86). The median ASA grade was 2 (79%). The dominant side was operated on in 68% of cases. A range of tear sizes were operated on (5 small, 17 moderate, 29 large and 18 massive). The tendons involved in the tear also varied (supraspinatus 12, supra and infraspinatus 53, supraspinatus and subscapularis 2, supraspinatus infraspinatus and subscapularis 2). Re-rupture occurred in 20 cases (29%). The mean Constant score increased from 23 (95% CI 19–26) to 59 (54–64) (P< 0.001). Where the repair remained sound, Constant score improved 42 points (95%CI 36–48). If the cuff re-ruptured, constant score also increased on average 12 points (95% CI 2–21). Re-rupture rate was highest for massive cuff repairs: ten out of eighteen (56%).Methods
Results
Many procedures have been described for the operative treatment of tennis elbow (lateral epicondylitis). Arthroscopic release is a relatively recent development. The aim of this study was to review our early results of arthroscopic tennis elbow release. This was a prospective study of 28 consecutive patients with tennis elbow refractory to conservative management, who underwent arthroscopic tennis elbow release performed by one surgeon. At surgery, arthroscopic joint assessment was performed followed by capsulectomy and debridement of the Extensor Carpi Radialis Brevis (ECRB) tendon origin using the proximal lateral and medial portals. The ECRB lesions were classified and resected with a shaver but the insertion site was not decorticated. Patients were assessed preoperatively, at 2 weeks and 3 months using the DASH score. Of the 28 elbows 21 were noted to have a Nirschl type I lesion (intact capsule), 6 had a type II lesion (linear capsular tear) and 1 a type III (capsular rent). Degenerative articular changes were noted in 19 elbows. If arthroscopic debridement was required it was undertaken. Three elbows were noted to have eccentric radial heads. Radial plicae which were impinging on the radial head were noted in three patients. 1 patient was lost to follow up. There was a significant improvement in DASH scores (p<
0.002) at 2 weeks post operatively. This improvement was sustained at 3 months. This is a worst case scenario analysis using a paired t test. 1 patient had post operative stiffness and 6 failed to improve of which 2 were revisions. The early results would suggest arthroscopic tennis elbow release is an effective treatment for tennis elbow, which in addition also allows assessment of the elbow joint and the potential to address associated intra-articular pathology. This minimally invasive technique has been demonstrated to be safe and affords early post operative rehabilitation.
Many procedures have been described for the operative treatment of tennis elbow (lateral epicondylitis). Arthroscopic tennis elbow release is a relatively recent development. The aim of this study was to review our early results of arthroscopic tennis elbow release. This was a prospective study of 29 consecutive patients (30 elbows) with tennis elbow refractory to conservative management, who underwent arthroscopic tennis elbow release performed by one surgeon. At surgery, arthroscopic assessment of the elbow joint was performed followed by capsulectomy and debridement of the Extensor Carpi Radialis Brevis (ECRB) tendon origin using the proximal lateral, anteromedial and anterolateral portals. Associated intra-articular pathology was noted. The ECRB lesions were classified according to their gross morphology and resected with a shaver but the insertion site was not decorticated. Patients were assessed preoperatively, at 2 weeks and at 3 months using the DASH score. 29 patients with tennis elbow were treated with arthroscopic release of the ECRB origin on the lateral epicondyle. Of the 30 elbows undergoing surgery, 22 were noted to have a Nirschl type I lesion (intact capsule), 7 had a type II lesion (linear capsular tear) and 1 had a type 3 lesion (capsular rent). Degenerative articular changes were noted in 18 elbows. Arthroscopic debridement was undertaken if appropriate. Three elbows had eccentric radial heads. Radial plicae which were impinging on the radial head were present in three patients. Mean follow up is 9 months (1–23). 1 patient was lost to follow up. There was a significant improvement in DASH scores (p<
0.05) at 2 weeks post operatively. This improvement became more significant at 3 months post operatively. This is a worst case scenario analysis using a paired t test. 6 patients failed to improve, 1 partially improved and 1 was revised and improved. There were no surgical complications; however, one patient has post operative stiffness which required an arthroscopic release. The early results of this study would suggest arthroscopic tennis elbow release is an effective treatment for tennis elbow, which in addition also allows assessment of the elbow joint and the potential to address associated intra-articular pathology if required. This minimally invasive technique has been demonstrated to be safe and affords early post operative rehabilitation and return to normal activities.
We aimed to test the biomechanically predicted hypothesis that in massive rotator cuff tears irreparable by conventional methods the newly developed Nottingham Augmentation Device (NAD) would provide greater functional improvement than that gained from the gold standard of arthroscopic subacromial decompression. Thirty patients treated between 2001 and 2004 were assessed by pre- and six month post-operative Constant scoring. Fifteen underwent open acromioplasty and cuff reconstruction using the NAD (mean age 67.3), while 15 underwent a standard arthroscopic decompression (mean age 67.4). The two groups were matched retrospectively based on size of cuff tear, age and sex. Data was analysed using the student’s t-test at the 95% confidence interval. Both groups displayed a statistically significant increase in Constant score after surgery. The mean increase for NAD patients was 18.7 points compared with 17.6 points for those undergoing arthroscopic decompression. However there was no significant difference between the two groups’ improvement and this was even so in the power sub-category, where increased benefit was predicted with the NAD. The NAD requires greater surgical access, operating time and peri-operative analgesia, and no active mobilisation for six weeks. The arthroscopic technique is minimal access, rapid, involves no prosthesis or foreign body insertion and allows immediate mobilisation. However, with clear biomechanical benefits of the NAD seen in vitro, our results may simply reflect cuff tears in an older population group with irreversible tissue changes and less rehabilitative potential. A randomised prospective trial in a younger patient group with more acute tears and less tissue atrophy would appear the next step in determining the NAD’s place in the management of massive rotator cuff tears.
We report the results of a method of reconstructing massive rotator cuff (RC) tears and reinforcing the repaired RC tendons with re-tensioning of the cuff to effect reconstruction of tears which were previously considered non-repairable.
