Clinical outcome after mosaicplasty of knee articular cartilage defects of patellofemoral joint versus tibiofemoral joint.

Background: The purpose was to investigate survival of cartilage repair in the knee joint by osteochondral autograft transfer stratified by location of the lesion; patellofemoral joint (N = 26) versus the medial or lateral femoral condyles (N = 58).

Methods: For survival analyses, "failure" was defined as the event of a patient reporting a poor Lysholm score (below 65 points) or undergoing a knee replacement procedure.

Results: The survival distribution was not significantly different between the patellofemoral joint and the tibiofemoral joint groups.

Long-term results after surgical treatment of subacromial pain syndrome with or without rotator cuff tear.

Purpose: Some studies suggest a common degenerative path might contribute to a range of shoulder diseases involving subacromial pain syndrome and full-thickness rotator cuff tears. One could therefore theorize arthroscopic subacromial decompression and rotator cuff repair as interventions at different stages of a degenerative shoulder disease. Few studies have compared long-term outcomes after these two procedures.

Long-Term Survival after Microfracture and Mosaicplasty for Knee Articular Cartilage Repair: A Comparative Study Between Two Treatments Cohorts.

Objective: To investigate survival of cartilage repair in the knee by microfracture (MFX; = 119) or mosaicplasty osteochondral autograft transfer (OAT; = 84).

Design: For survival analyses, "failure" was defined as the event of a patient reporting a Lysholm score <65 or undergoing an ipsilateral knee replacement. The Kaplan-Meier method was used for construction of a survival functions plot for the event "failure.

Early determinants of long-term clinical outcome after cartilage repair surgery in the knee.

Purpose: To identify early determinants of clinical outcome after knee cartilage repair.

Methods: 205 patients were evaluated before surgery and at median 14-years follow-up.

Results: Baseline factors predicting a good outcome were: single lesion; normal appearing cartilage surrounding the lesion; high baseline Lysholm score; short duration of symptoms; non-involvement of the patella-femoral joint; young age; and small defect.

Randomized Study of Long-term (15-17 Years) Outcome After Microfracture Versus Mosaicplasty in Knee Articular Cartilage Defects.

Background: Few comparative randomized long-term studies on microfracture versus mosaicplasty have been published, and only 2 studies reported a follow-up of 10 years. Hypothesis/Purpose: The purpose was to compare the clinical outcome of microfracture versus mosaicplasty/osteochondral autograft transfer in symptomatic cartilage lesions. The null hypothesis was that the outcome was not statistically different at any point of time.

Long-term clinical follow-up of microfracture versus mosaicplasty in articular cartilage defects of medial femoral condyle.

Background: The purpose of this study was to evaluate the outcome after cartilage repair surgery in focal defects of the knee by microfracture versus mosaicplasty.

Methods: A cohort of 102 patients undergoing microfracture (n=52) or mosaicplasty (n=50) of a single articular cartilage defect in the medial femoral condyle of ≤50mm was evaluated by Lysholm score before surgery, at six months, 12months, five years, 10years, and 15-18years after surgery.

Results: Median age of patients at the time of surgery was 36years (range 16-58) and median follow-up time was 16years (range 14-18).

Arthroscopic Treatment of Lateral Epicondylitis: Tenotomy Versus Debridement.

Purpose: To compare the outcome of 2 arthroscopic techniques for treating recalcitrant lateral epicondylitis.

Methods: The study included patients undergoing arthroscopic treatment of lateral epicondylitis during 2 different time periods: April 2005 to October 2007 (tenotomy) and May 2009 to June 2010 (debridement). By using a patient-administered form, baseline information including QuickDASH (disabilities of the arm, shoulder and hand) score (primary outcome), visual analog scale (VAS) of pain, and VAS of function was recorded prospectively.

Preoperative NSAIDs, non-acute onset and long-standing symptoms predict inferior outcome at long-term follow-up after rotator cuff repair.

Purpose: To evaluate mid- to long-term results after arthroscopic rotator cuff repair and to explore possible predictors of inferior outcome.

Methods: Patients treated for full-thickness supraspinatus and/or infraspinatus tears from 2004 to 2008, using a uniform single-row arthroscopic technique, were included in the study. Pre- and post-operative QuickDASH were used as the primary outcome measure, and VAS of pain, function and satisfaction were also collected.

Long-term outcome after all-inside meniscal repair using the RapidLoc system.

Purpose: The purpose of the present study was to evaluate the outcome at a minimum of 7 years following meniscal repair using the RapidLoc (suture anchor) system. It was hypothesized that most patients would have an intact meniscus, as has been reported in several short- and medium-term studies.

Methods: In the time period from 2002 to 2007, all patients with a vertical longitudinal tear of the meniscus that was judged to be repairable were treated with rasping of the tear area and nearby parameniscal synovium and fixation of the torn part with the use of RapidLoc implants.

Results at 10-14 years after microfracture treatment of articular cartilage defects in the knee.

Purpose: To evaluate the long-term clinical outcome after microfracture treatment of focal chondral defects of the knee and to investigate possible early determinants of the outcome.

Methods: A prospective cohort of 110 patients, treated with microfracture, was evaluated at a median of 12 years (range 10-14) by Lysholm score, VAS of knee function and VAS of knee pain. Pre- and perioperative information was collected, and additional surgery to the same knee during the follow-up period was recorded.

Results at 10 to 14 years after osteochondral autografting (mosaicplasty) in articular cartilage defects in the knee.

Purpose: The aim of this study was to evaluate the medium-term (5-9 years) and long-term (10-14 years) outcomes of mosaicplasty in the knee and identify possible risk factors for poor outcome.

Methods: We included patients 60 years or younger with symptomatic focal full-thickness chondral lesions. Seventy-three patients (87%) with median age of 34 years were available for analyses.

Arthroscopic versus open tennis elbow release: 3- to 6-year results of a case-control series of 305 elbows.

Purpose: The purpose of this study was to compare the outcome of arthroscopic and open tendon release in tennis elbow (TE).

Methods: We compared the outcome of patients treated by an open tendon release in the period from 2002 to 2005 (n = 80) with that of patients treated by an arthroscopic release of the extensor carpi radialis brevis in the period from 2005 to 2008 (n = 225). In both groups the inclusion criteria were symptomatic TE refractory to conservative care for a minimum of 6 months and a clinical follow-up of at least 3 years.

Extensor tendon release in tennis elbow: results and prognostic factors in 80 elbows.

Purpose: The objectives of this study were to evaluate the results in the outpatient treatment of recalcitrant lateral epicondylitis with release of the common extensor origin according to Hohmann and to determine any prognostic factors.

Methods: Eighty tennis elbows in 77 patients with a characteristic history of activity-related pain at the lateral epicondyle interfering with the activities of daily living refractory to conservative care for at least 6 months and a confirmatory physical examination were included. Clinical outcome was evaluated using the QuickDASH score system.

Microfracture treatment of single or multiple articular cartilage defects of the knee: a 5-year median follow-up of 110 patients.

We compared the results of microfracture in single versus multiple symptomatic articular cartilage defects in the knee in 110 patients with a median age of 38 years (range 15-60). Cases of reoperation of the cartilage defect were classified as failures. Clinical outcome in non-failures was evaluated by the Lysholm score and grading of knee pain and function of the knee by the use of patient-administered visual analog scales (VAS; 0-100).

Osteochondral autografting (mosaicplasty) in articular cartilage defects in the knee: results at 5 to 9 years.

We evaluated short- and medium-term results of the treatment of articular cartilage defects of the knee with autogenous cylindrical osteochondral grafts (mosaicplasty) in 69 patients (median age 33 years) with symptomatic articular cartilage defects. Data of Lysholm score and visual analogue scale (VAS) of pain (0=no pain; 100=worst possible pain) were collected before the surgery, at 12 months postoperatively and 5 to 9 (median 7) years after the surgery. At the last follow-up the patients were also asked to state their degree of satisfaction with the outcome on a VAS (0=not at all satisfied; 100=completely satisfied), and to answer if they would have undergone the surgery again if necessary (yes or no).
